THE following brief essay on the Patent System of the United States contains information which the writers believe has not heretofore been collected in a treatise of reasonable compass. To obtain such information inventors have been compelled to resort for some items to the Patent Laws, for others to the Kules and Regulations of the Patent Office ; while others of great importance have been, to all practical intents, locked up in elaborate volumes to which none but a professional man could be ex- pected to give the requisite time and attention. The aim in the following pages has been, in part, to collect and con- dense information concerning the general features of the law, illustrating it, where necessary, by reference to general principles. In doing this it has been pertinent to enter at some length into those questions of public justice and policy upon which property in invention is founded, and to explain the true position of inventors in relation to the public. Official examination, previous to the grant of patents, has been treated at some length, and necessarily in a controversial way, the en- deavor being to meet, in a fair and scrutinizing spirit, the usual objec- tions to the system, to point out wherein it may be really deficient, and how capable of remedy these deficiencies are. We believe that the question is fairly stated, and candidly considered, and we trust that our readers will conclude with us that whatever may have been the defects in the examining system, they are suscep- tible of remedy, and that all defects admitted, the system may yet be regarded as one of the most efficient of those causes which have given patent property, here, a certainty and commercial value, such as it pos- sesses in no other patent-granting country. It is proper to state that our remarks upon the main defect, want of uniformity, in the examining system, and our suggestions as to the (3) PREFACE. remedy are for the most part based upon observations made by the Hon. M. D. Leggett, the present able Commissioner of Patents, who, while keenly alive to the defect alluded to, is not in the least doubtful of the feasibility of measures by which it may be remedied. To the facts and arguments adduced in support of the examining system additional point is given, by reference to foreign testimony as to the evils arising from the grant of patents without previous examina- tion. It was considered pertinent to do this, because, recently, it has been hinted in sundry quarters that the abandonment of previous exam- inations would be a desirable improvement in our law. That such a change would be anything but desirable we think our readers can hardly fail to conclude, when they peruse the weighty evidence collected in these pages against a haphazard, undiscriminating grant of patents. The concluding chapters of the treatise touch upon other leading fea- tures in our patent law. Disclaimers, reissues, caveats, interferences, suits for infringement, &c., are treated of, necessarily, with great brevity, but not too briefly, it is hoped, to convey that rudimentary knowledge of the subject which every person interested in patent property should acquire. Anything like the thoroughness of a legal text-book is, of course, not to be expected within so brief a compass, and in fact anything beyond generalization has been carefully avoided, the object being simply to map out those common principles and incidents which are of everyday application in dealing with property in original invention. In the book is incorporated the text of the law concerning patents, trade-marks, and copyrights ; those sections of the law bearing upon questions treated in the body of the book being there referred to by number. It is hoped that inventors and patentees will find the treatise a ser- viceable manual of information touching matters greatly concerning their interests. H. & C. HOWSON. THE AMERICAN PATENT SYSTEM. CHAPTEK I. HISTORY OF PROPERTY IN INVENTIONS. AN inquiry as to the principles and object of the American Patent System, may perhaps be made more clear if introduced by a brief his- torical retrospect. The English "Statute of Mo- nopolies," James I, 21st, is the earliest legislative recognition of the public policy of allowing temporary exclusive rights in the exercise of new manufactures. This statute declared utterly illegal and void, those royal grants for the sole buying, selling, working or using of different things within the realm, which, under the name of patents, had become odious from their mischievous and oppres- sive results. But from the general condemnation of monopolies, the act excepted, under certain qualifica- tions, patents for the sole working or making, during a limited period, of any manner of NEW manufac- ture, which others, at the time of 'inakinij such letters-patent should not we. To the Anglo-Saxon mind jeal- ous of anything tending to re- strain free action, and jealous, es- pecially, of any extraordinary in- struments of taxation monopolies in trade or art, or in the making or vending of necessary or useful articles, were utterly abhorrent. But the declaratory character of this statute shows that previously, at common law, it was recognized as a lawful prerogative of the Crown to grant to the inventors of new manufactures the sole right, for lim- ited periods, of working such manu- factures within the kingdom, and records of such grants are to be found, dating so far back as the time of Ed- ward III. As explained by Lord Eldon, this was a prerogative vested in the Crown as the depositary of the su- preme executive power of the state, to be exercised in behalf of and for the benefit of the public. But, as may be well understood, a royal prerogative of granting Pat- ents of Monopolies, so long as its true object remained undefined and its exercise unregulated by express legislation, was exceedingly likely to be diverted from its legitimate uses and employed for the private advan- tage of the monarch, or of royal favor- ites, to the grievous disadvantage of the public. And so events proved, for (5) History of Property in Inventions during the reign of Elizabeth especi- ally the prerogative was so stretched and perverted as to produce general mischief and complaint, which finally led to the passage of this Statute of Monopolies, the effect of which is to define the real extent and object of the royal prerogative with reference to the grant of patents affecting the exercise of trades. It is not our purpose to pursue this historical inquiry further than to point out that the common law of England early recognized the public policy of granting exclusive privileges in the exercise of new trades, and that the public advantage arising from the introduction or dis- covery of a new art or trade was re- garded as being that which alone warranted such grants. The words "true and first in- ventor," as used to this day in Eng- lish Patent law, include not only him who may first devise or discover something new, but him also who may first make known within the kingdom something which has been invented abroad. The reason of this is readily un- derstood when we consider the char- acter of the times in which the Eng- lish law on this subject may first be traced. The insular position of England and the imperfect, not to say dangerous character of travel, isolated her from the rest of the civilized world. Communication was limited and infrequent, and in every country patriotism took the shape of extreme jealousy of for- eigners. It is not hard to believe, then, that to import knowledge of an art from abroad was no small achievement, but might be regarded as rare merit. Thus in the Clothmakers of Ips- wich case, adjudged in the reign of James I, it is said, "If a man hath brought in a new invention and a new trade within the king- dom, in peril of his life and consump- tion of his estate or stock, &c., or if a man hath made a new discovery of anything, in such cases the King, of his grace and favor, in recom- pense of his cost and travail, may grant by charter unto him that he, only, shall use such a trade or traf- fique for a certain time, &c." To the development of invention in the sense of originating and de- vising, neither the intellectual nor the social condition of these early times was favorable. The mass of laborers and artisans were little more than human ma- chines, running in one rut, and as a rule lacking the desire or the intel- ligence to seek to better their modes and means of working, while the in- tellectual efforts of those of higher rank and educated intelligence were not as yet fairly diverted from the unprofitable channels and myste- rious lore of a false and unprofit- able philosophy. Bacon's works were but now startling the edu- cated few, and the leaven of that practical and humane philosophy of which he was the first great exponent had yet to commence its work on History of Property in Inventions. men's minds. The science of the times was perfectly barren. The artisans were not thinkers, and the thinkers had no acquaintance with the practical arts. There was yet a gulf, partly of social and political and partly of educational creation, sepa- rating cultured intelligence and practical industry, which must be allied before there can be fruitful invention. Kor were the political troubles of the time, succeeded as they shortly were by internal war, favorable to the development of the industrial arts. Moreover the science of phys- ics was yet to be reduced to rational principles, and new modes of thought to be developed, and this was the slow work of years. The applica- tion of science to the practical arts must come later. It is not to be wondered at then, that, as is observed in the excellent treatise of Hindmarch, " for many years after the passing of the statute of monopolies the arts and manu- factures continued in a low state in England ; few of the inventions for which letters-patent were ob- tained were of any value, and the demand for novelties being very limited, no one was tempted to in- fringe the rights of patentees." It is not until the reign of George III that we find the subject of prop- erty in inventions attracting public attention. Then the troubles of Arkwright and of Watt, brought the subject of patents into court , and led to the earliest of that series of judicial reasonings upon the English law of patents, which gives that law what it has of system. We need not wonder that the early treatment of patents in the English courts was anything but liberal. The subject was a strange one, coming before them at a time when a very clear and high concep- tion of the importance and merit of inventors could hardly exist. In later years, as the exercise of the inventive faculties became more general and active, and had pro- duced results which forced a per- ception of the importance and value of original invention upon the public mind, a more liberal treatment of patents crept into the judicial prac- tice ; and the English patent law as it stands to-day is for the most part judge-made law, whose doctrines are founded upon reasoning as just and liberal, perhaps, as the bounds of the old legislation forming the text for the judicial commentaries will permit. The apparent public policy of en- couraging improvements in the use- ful arts, has led to the adoption by most civilized countries of patent systems more or less analogous to that of England. The earliest to adopt such systems were France and the United States. Our own patent system, first es- tablished by Act of Congress, in 1790, and gradually developed and improved by subsequent legisla- tion, is based upon reasoning which History of Property in Inventions. seeing, on the whole, peculiarly cor- rect, just, and liberal. It originated at a time and under circumstances favorable to the de- velopment of inventive activity, and which allowed a clear perception of the importance of invention to the domestic progress of the useful arts and its consequent utility, to society. This led to a recognition of the principle ofprhxtterigkt which really underlies a patent system, and of the broad difference between patent privileges and monopolies, so called. A monopoly in its legal and odious ' sense, implies the taking away of [ some right from the many, for the benefit of particular individuals. Manifestly, then, the term is not applicable to letters-patent for new inventions ; that cannot be taken from the public, which the public has not ; a new invention or discov- ery can become public property, only by communication from the inventor or discoverer ; until so com- municated voluntarily, it * remains the secret property of the latter. This view of the case shows that into the public policy of patents enter important considerations of public justice, an idea upon which we shall have occasion to dwell more fully in the course of this treatise. Looking to the question how far our patent system may be adjudged from experience to have proved con- sistent with the principles of justice and policy upon which it is based, we find, to begin with, that the number of patents issued in this country, is very largely in excess of that in any other patent-granting country ; that there is here a more general and widely-spread inventive activity than elsewhere ; that Amer- ican labor-saving machinery and devices are in demand the world over ; and that inventors enjoy in this community, a power and con- sideration without parallel abroad. The vast amount of work to be done in developing the resources and industries of this new coun- try, by a comparatively small and scattered population, with moderate pecuniary resources, has made labor- saving mechanism a peculiarly ser- viceable instrument of power, sup- plying the place of manual lalxr with greater accuracy and economy, and so increasing the productive power of capital. Thus, it is because of its pecu- liarly manifest utility to the public, that invention has here attained such dignity. How far has this been brought about by our patent system ? or in other words, how far has that sys- tem tended to incite and foster the exercise of ingenuity . Our Patent Laws are, undoubted- ly, the most truly liberal of any. They more clearly than any other recognize the truths that productive industry is the basis of national wealth and power ; that such indus- try will nourish in proportion as it is made a secure source of indi- vidual profit ; that true invention is intellectual production of the most General Principles Governing Property in Inventions. 9 beneficial kind, and that, therefore, true policy, which is always just, demands that it shall be made, as far as posssible, a secure source of individual profit. The benefit of the patent laws has been sought with avidity, and there can be no doubt that the advantages which they hold out have led to a multitude of inventions and novel disclosures, which otherwise had not been made. But many Complaints and criui- cisms have been directed against the patent laws and their adminis- tration (some of them more or less just, no doubt, since an absolutely perfect system of human designing is hardly to be looked for), but for the most part we think fallacious and arising from a misapprehension of the true principles of the law. This misapprehension, it is be- lieved, is to be traced in great de- gree to the just favor and consider- ation with which inventors have been regarded, leading gradually to a somewhat one-sided and partial understanding of the laws affecting them. CHAPTER II. GENERAL PRINCIPLES GOVERN- ING PROPERTY IN INVENTIONS. IT is our purpose in this chapter to inquire first into the true nature and purpose of patent laws, for it is necessary to- ascertain this, before we can look with intelligence into the question of the justice and effi- ciency of our own law. The patent laws, as viewed in reference to inventors only, are the means of securing temporary exclu- sive rights to the use of new and useful inventions, and it is not un- natural that inventors themselves should regard the laws in that light only. So viewing them, regarding themselves as the only parties inter- ested, they will look with impa- tience and disfavor upon those fea- tures in the laws, or the administra- tion of them, which may seem mere embarrassments or impediments in the way of obtaining patents. Yet this is not a true, because only a partial, view of the subject. It would be an unprofitable and unnecessary task to touch upon the question of man's natural property in his own original ideas. It is suffi- cient to recognize the fact that as long as they are locked up in his own breast, they are likely to be of little benefit to himself or any one else ; to be of use they must, as a rule, be disclosed ; and when once disclosed, they cannot be stamped with the character of individual property, and be identified and protected as such, except through the medium of positive legislation. But society can be looked to for such legislation only if, and so far as it may be, consistent with the general welfare. Consequently it is in iitility to society that we must seek the rea- son and justification of positive laws recognizing individual rights in con- nection with invention. 10 General Principles Governing Property in Inventions. The progress of the useful arts is a most important branch of the general welfare, and inventors are the chief instruments for the ad- vancement of the useful arts. An inventor is not bound to disclose his invention ; he may, if he so elect, keep the knowledge of it to himself, but generally he cannot himself profit by its use, without, in the very act, disclosing it to others, and when thus disclosed, there is nothing in the absence of positive law on the subject to prevent other members of the public from avail- ing themselves of an idea, which has then in a certain sense become public property. Evidently, in a state of society where for an inventor to disclose his invention is altogether to lose, with- out return, the special benefit of it, and of the labor and expense he may have bestowed upon it, there is little or no encouragement for the exercise of ingenuity, and the ex- penditure of thought, time, labor, and money in the bringing to light of new inventions. Men Avill not wil- lingly sow merely for others to reap. It may be said that the inventor derives a profit from his original thought, in the advantage which it gives him over competitors, by way of increased facilities or economy in the prosecution of his business. But if he cannot hope to maintain this power longer than he can keep it secret, but must upon accidental disclosure share his advantage with all his competitors, so that he will then occupy no better position rel- atively than before, plainly the in- ducement to invention is small in- deed. It is to be considered, moreover, that in an active condition of the inventive mind, a vast number of original ideas must be produced, which have no relation to the par- ticular employment of the inven- tors, and for the encouragement of such a general active condition, therefore, some special inducement must exist. Some few inventions there are which may be practiced in secret, and no doubt valuable and import- ant discoveries have in this way died with their originators, and so been lost to the world. Of such conceal- ment it is desirable that there should be as little as possible, not only be- cause it tends to deprive the public of useful knowledge, but because it tends to destroy confidence, and arouse doubt and suspicion, hamper- ing business, and interfering with peace and good order. The conceal- ment of inventions, where it may appear practicable, will, perhaps, always be to some extent indulged in, but it is evidently impolicy on the part of the public to encourayc such concealment, by totally ignoring the interests of inventors. The mischiefs, public and private, likely to proceed from compelling inventors to secrecy, have been thus forcibly represented by an accom- plished writer : " A manufacture conducted in se- General Principles Governing Property in Inventions. 11 cret, is at an enormous disadvantage. Processes must be separated, that the workman may not apprehend the mystery ; immense wages must be paid to retain them from desert- ing to competitors ; simplicity must be avoided, and expense introduced, for no purpose but to complicate and confuse the methods used. Ex- periments for further improvement must be avoided, for they would not only tend to disclosure, but to the loss of the outlay incurred in estab- lishing the existing expensive meth- ods. After all, if the attempt to maintain the secret were successful, the public would be no gainers, for it would constitute a strict mo- nopoly, and, unlike a patent, a mo- nopoly that would be lasting either till the secret was discovered, or till it died with its first employers." To this it need only b*e added that in such a state of affairs, many im- portant improvements would be for- ever lost, from the inability of the in- ventors to undertake the burden of practicing them secretly, and their natural unwillingness to run the risks of disclosing them to persons who might assume that burden. The relative positions then, of the public and inventors, and the conse- quences proceeding therefrom, may be thus summarized : I. The public is vitally interested in the progress of the useful arts, and to this progress the production and disclosure of original invention are essential : it is the clearest public policy to encourage such production and disclosure by any proper means. II. Inventors, in producing and disclosing improvements in the use- ful arts, add materially to the pub- lic stock of wealth and power, and are therefore producers of the high- est order ; and as payment is the rightful consequence of physical or mental labor, time, and capital ex- pended in production, it would seem the clearest public justice that some mode should be provided of remune- rating inventors in proportion to the value of their productions and dis- closures. III. From the preceding proposi- tions it follows that the public object of promoting the progress of the useful arts is that which allies the interests of the public and those of inventors. The consideration which passes from the inventor to the pub- lic, entitling him to some return, is his contribution to that progress. We come then to the conclusions that, practically speaking, the rights of inventors, as such, are those cre- ated by positive legislation ; and that the object of legislation, in creating such rights, is to promote the progress of the useful arts by pro- viding some mode by which inven- tors may be remunerated for their instrumentality in promoting that progress. Thus we find the true object of our own patent system in the title of the original act of 1790, and of the succeeding acts: "An Act to pro- mote the progress of the useful arts. " 12 Of Patents as a Mode of Remunerating Inventors. CHAPTER III. OF PATENTS AS A MODE OF RE- MUNERATING INVENTORS. THE propositions admitted, that it is both politic and just having regard to the progress of the useful arts to provide some mode in which inventors may derive personal profit from their contributions to that progress, the next point to be as- certained is the best mode. That which is the most obvious, is the payment by the state of a stated price or premium, but there are many and obvious objections to this mode. It could not be practi- cally carried out with even justice to the public and to inventors, and it would entail a cumbrous and ar- bitrary system peculiarly open to abuse. It would be necessary either that the law itself should ascertain and fix valuations for inventions generally manifestly an absurd and impractical thing, and one which, if attempted, would work injustice, sometimes to the public, and sometimes to inventors, or the fixing of values must be left to tribunals, whose decisions would, of necessity, be arbitrary and un- satisfactory, since they could not apply to the determination of the question the only reasonable and just test, that of experience. These, and other objections equally obvious, but to which it is not to our purpose here to allude, make it plain that a system of this kind would not well answer the end of promoting the progress of the useful arts. The objections which we have cited, going to show what is not a good and efficient mode, point to the principles necessarily governing a mode which is so It is just and proper that a new and useful invention should be paid for by the public, in proportion to its proven value to the public, and that the mode of valuation should be the same as in the case of other products of individual skill and labor. The public verdict, as evidenced in demand, is the best general test of the value of an article, and the profit derived from manufacture and sale, if these be carried on with proper enterprise and discretion, will be in proportion to the value. This is the philosophy of that mode of paying inventors which is known as the patent system ; a mode the most just and reasonable that could be devised. Letters-patent grant to the in- ventor of a new and useful improve- ment the exclusive right, for a stated period, of making, using, and selling such improvement If an invention thus secured for a time by patent be really valuable and important, it is of course desi- rable that it should be brought into public use as speedily and widely as possible, and here the interests of the public, and those of the in- ventor are alike, for the advantage which the latter can derive from Of Patents as a Mode of Remunerating Inventors. 13 his patent, must altogether depend upon his diligence and discretion in availing himself of the exclusive right which it gives him. If, on the other hand, the invention be of no value and importance, the exclusive right of the inventor is altogether harmless ; it will be practically no restraint upon the public, and will bring the inventor no more than he is entitled to. Patents in so far as they operate as a restraint upon the public are yet decidedly beneficial restraints, for during the term of the inventor's exclusive right, the public are bene- fited in the open practice by the in- ventor himself, or those acquiring the right from him, of an invention, which, but for the prospect of that right, might not have been made, or having been made, might not have been disclosed. So far as the exclu- sive right operates as a tax upon the public, it is a tax justly proportion- ate to the ascertained value of the consideration given by the inventor ; and after the exclusive right has expired, the public freely use the invention themselves, being enabled to do so by the knowledge which the inventor has imparted to them. These then are the principle and the object of a patent system : to pro- mote the progress of the useful arts by extending to inventors that en- couragement to exert their inge- nuity, and disclose their inventions, which can be given with most ad- vantage, both to the inventor and the community, in the shape of a 1 temporary exclusive right to the former to make, use, and vend his invention. Thus viewed, the patent laws as- sume the aspect of a compact be- tween inventors and the public, by which the public in consideration of the disclosure by the inventor of an original thought which it is not compulsory upon him to disclose, yet of which, without such disclo- sure, neither he nor they can have the use and enjoyment, undertake to secure to him for a limited period, by positive grant, that exclusive right in his invention, which with- out such positive grant, it would be impossible for him to maintain. The policy of patents as a means of promoting the progress of the useful arts, has been disputed, never seriously, however, in this country. In England the proposition has been made, and urged more loudly than forcibly, to abolish patents ; but there the would-be abolitionists are a very small minority, and their views have been vigorously and suc- cessfully combated by some of the ; leading intellects of the country. Holland stands alone as the coun- I try which has abolished patents. : The abolition occurred in 1869, the royal proclamation stating that " the grants of exclusive rights for inven- tions and improvements or importa- tions of objects of art and industry promote neither industry nor public interest." In its experience on this subject, Holland seems to be as exceptional 14 Of Patents as a Mode of Remunerating Inventors. a country as it is in everything else. "Such a land as Holland," says a recent American writer, "exists nowhere else. It is not merely the .most singular of kingdoms, it is the only one of its kind. You may travel the world over and yet be unable to form any conception of the Nether- lands. You may live there your life long, and form no adequate idea of the remainder of the globe." It is not at all unlikely that among a people so conservative and self- satisfied as the Hollanders, patent laws did not promote industry. The people, though robust, brave, and industrious, appear to have a horror of innovation, as is attested by their obstinate adherence to sleighs in place of wheeled vehicles, for draw- ing heavy loads over rough pave- ments. Little progress in the useful arts is to be expected in a country where men and horses continue to be shod with wood, and where men, women, and children are still to be found yoked to the same tow ropes with dogs and donkeys on the banks of the interminable canals. It may be very true that the Dutch patent law did not promote the pro- gress of the useful arts in Holland ; great progress would scarcely be ex- pected among a people so obstinately conservative, no matter what in- centives were offered ; but the Dutch law was so intensely selfish in its character that it would scarcely l>e expected to promote any public ad- vancement in the arts, one of its prominent clauses being to the effect that a native forfeited his patent if he secured his invention in any other country.* The patent abolitionists were un- fortunate in pointing to the example of Holland, a country where the limited manufacturing interests are at a standstill, if not retrograding, and where the prominent products are gin, tulips, and cheese. Switzerland, a country which never possessed any patent laws, is also pointed to by the advocates for the abolishment of patents. In re- spect to Switzerland, Mr. Day, in his able papers read before the Philo- sophical Society of Glasgow, papers from which we shall have to quote hereafter, says : " When do we hear of an important invention coming to maturity in this country ? There is plenty of inventive talent in Switzerland, but Swiss inventors lack the stimulus of a patent law, and, therefore, have to come here or go elsewhere where an invention can be patented, and is recognized by the state as bond fide property." To again quote from Mr. Day's book: "The patent system is the only one by which a nation can secure the maximum advantage from the invention, the only one by which in- vention is properly encouraged, the only one by which the real value of * A Dutch legislator, in advocating the aboli- tion of patents, declared that it was useless to point to the United States and England in sup- port of Patent laws, because those countries were in a degenerate condition, not better than that of Holland at the close of the sixteenth century. Essential Features of a Good Patent System. 15 an invention can be ascertained, and, therefore, the only one which can secure not merely reward, but a due reward, precisely its exact worth to the inventor." CHAPTEE IV. ESSENTIAL, FEATURES OF A GOOD PATENT SYSTEM. ASSUMING it to be politic and just to provide some mode in which the public shall pay inventors for their contributions to the progress of the useful arts, and that the best mode is by a properly devised patent system, we come next to consider what should be the characteristics of such a system. Undoubtedly the soundest patent law is that which treats inventors with the most liberality, on the plain grounds that the more liberal the law, the more it is likely to answer its pub- lic purpose of promoting the prog- ress of the useful arts, by induc- ing the production and disclosure of new inventions. But this idea of liberality to in- ventors is not to be carried so far, as to lose sight of the public object of the law, and of the fact, that having a reference to that object, inventors are simply the instru- ments and means. In other words, it is not to be forgotten that the utility of inventors to society is the consideration upon which the legal rights peculiar to them as inventors are based ; that they occupy pre- cisely the same footing as other pro- ducers to the public stock, and that society, in contracting to pay them, has the right to establish such pro- visions and conditions, as are neces- sary to assure that in each case the effect of the contract shall accord with its object and with the general welfare. If these principles were continu- ally and clearly borne in mind, we should have less of that criticism of the patent laws, based upon the false assumption, often expressed, that their one object is to " pro- tect inventors." That is their end so far as concerns, the particular interests of inventors, but they have a superior and public object, that of promoting the progress of the useful arts ; with reference to this object, the "protection of in- ventors " is simply the means. The proper liberality of the law to inventors is based not upon poetic sentimentality but upon per- fectly utilitarian grounds and princi- ples of practical justice. Of the patent laws, therefore, as of any other contract, the justice is to be measured by the degree to which they appear to consult and recon- cile the interests of all parties con- cerned, and to proceed upon the truth that the intended beneficial operation of the bargain must be destroyed by any provisions tend- ing to antagonize the interests of the respective parties. If this test be applied to our own patent system, we believe it will be 16 Essential Features of a Good Patent System. found that the provisions and con- ditions which seem to he in the in- terests of the public, are also really to the advantage of inventors ; that the same precautionary measures work to the profit of both parties to the contract. But before proceeding to apply the test, let us see what are the leading principles which, having due reference to the object to be attained, may be considered as essential to be recognized and followed by any sound patent law. It is evident, to begin with, that new and useful inventions only, can be the subject of valid patents ; for if an inventor produce and dis- close something which is not new, or something which cannot be used, or which it is against the interest of society to allow to be used, he simply gives society -that which it had before, or that from which it can derive no benefit : which is to give nothing ; so that society owes him nothing. A patent, therefore, granted for such an invention, would be invalid for want of consideration. Presuming the invention to be new and useful, it is no less essen- tial to the validity of the patent that it shall have been fully and fairly disclosed by the inventor; other- wise his part of the compact has not been carried out in good faith. There must be no concealment, no deception, but the information given must be sufficient to guide those skilled in the art to a beneficial use of the invention, so that the public may fully and freely advantage by it after the expiration of the patent. In addition to this it is essential that the inventor shall have clearly pointed out and particularized what he claims to be original with him, that the public, during the existence of the patent, may be fully advised as to the nature and extent of the exclusive right which it confers, and as to what it is they are restrained from making, using, or selling, save with the permission of the patentee. As to this there should be no dis- simulation, duplicity, or dubious- ness, but a clear and candid state- ment of claim. Now it is manifestly just both to the public and inventors to insure as far as possible that none but patents shall be granted ; that is to say, such as do in truth bestow that exclusive right which they purport to bestow. This is just to inventors, because the value of patent property, as of any other, is in proportion to its ascertained degree of certainty and security; and just to the public, be- cause the issue of valid patents only is plainly an important element in the efficiency and public advantage of a patent system. It would seem then to be the important end to which the provi- sions of a patent law should pri- marily be directed, to confine the issue of patents as far as possible to inventions new and useful, clearly disclosed, and distinctly claimed. A second object to be realized to American Patent System Previous Official Examination. 17 the fullest extent possible, consis- tently with the maintenance of the first, is that patents shall be easily, speedily, and cheaply attainable, so as to be within reach of rich and poor alike. Here, too, the interests of the public and inventors are identical, for the more easily and cheaply rame fallacy is based a very common ac- cusation of injustice against the ex- amining system and its adminis- tration. It is often gravely ob- jected, and was so but a short time since by one of our leading public journals, that the power conferred upon the officers of the patent office, of judging upon the rahte of inven- tions, is too arbitral-}' and danger- ous a power. So it would be if it did but exist. This objection in fact evidences a popular recognition of the truth which we have been endeavoring to illustrate, that an examining system extending to the question of value could not be justly ad- ministered. To the assertion that no such power exists, it may be re- plied that officers of the patent office have been known to exercise such a power. True enough, and this merely goes to show that among the numerous officials of the patent office some may, from time to time, be found who, from misunderstand- ing of duty, exceed their powers, and usurp an unlawful jurisdiction. That ordinarily no such power is attempted to be exercised is best proven by the large number of pat- ents issued for things of indifferent value or of no value at all. This fact, used as an argument against the efficiency of the examining sys- tem upon the hypothesis that an inquiry into value is part of that Previous Official Examination. 23 system, exposes at once the fallacy of that- hypothesis, and that of the allegation of injustice based upon it. Returning to the fact that officers of the Patent Office have been known to exceed their duty, by pronouncing judgment upon the value of inven- tions, this of course is a just ground of complaint, certainly, however, not against the examining system, in a departure from whose princi- ples the wrong consists. If the wrong were prevalent, there would be very good ground for as- serting that the administration of the law was not in accordance with the law ; but that the wrong is not prevalent the patent lists are con- vincing proof. Still another very common falla- cy is that which holds the examin- ing system responsible for the many patents of little or no value, not because they refer to inventions of little or no value, but because the specifications and claims have been defectively and insufficiently drawn. This is something for which the patentees are alone responsi- ble ; it is at once their privilege and their duty to specify what it is they claim to have invented. The functions of the officers of the Patent Office are advisory no fur- ther than to ascertain before grant- ing a patent that the alleged inven- tion is intelligibly described, and that the claim made is certain and distinct. This much they must of necessity do in undertaking to look into the question of novelty and utility. And if the description be not sufficiently clear, or more is claimed than the applicant is enti- tled to, it is their duty to tell him so, that he may amend or modify his de- scription or claim accordingly. But it is no part of their duty to volun- teer information that less has been stated or claimed than might have been ; this would be uniting the functions of judge and counsel, and assuming a duty which the law very properly leaves to the inventor him- self. It is a fair presumption that the inventor is a competent guar- dian of his own interests, so far as concerns the disclosure of his own ideas, and the presentation of his own claim. That he will claim less than he thinks himself entitled to is not to be supposed. Kor does the case differ, though the inventor him- self be incompetent to state his in- vention and claim with proper skill, for in such case it is incumbent upon him to seek the counsel of those who can perform this duty for him. The strict impartiality requi- site to the faithful performance of the duties of an officer of the Pat- ent Office must prohibit any such officer from placing himself in the position of an advocate for the in- ventor whose claim he is to pass upon. It is a common expression that the Patent Office is the guar- dian of the interests both of inven- tors and the public ; and this is true so far as its meaning refers to the exercise of careful and impartial dis- 24 Ordinary Criticisms of the Patent Office Considered. crimination and judgment in pass- ing upon claims of invention. It is the duty of the Office to give the patent asked for, if the claimant appears entitled to it, or to give him information as to any facts which may appear to render the claim made inadmissible. The rest may well be left to the inventor himself, for he is to be dealt with as an tu- telliyent man, capable of taking care of his own interests, and not as an incompetent under wardship. CHAPTER VI. ORDINARY CRITICISMS OF THE PATENT OFFICE CONSIDERED. THE observations in the preceding chapter show that the true crite- rion by which the efficiency and jus- tice of the examining system is to be measured, is not the number of pat- ents for things of indifferent or no value, nor the number of patents with indifferent claims. The true question is, how far has the administration of the examin- ing system been successful in pre- venting the issue of patents for old or unpatentable inventions, or for inventions previously patented ? and how far has its success in this direc- tion been neutralized by accidents and shortcomings injurious to in- ventors and the public ? The efficiency of the administra- tion of the Patent Office, in this re- gard, may be superficially illustra- ted by official figures. Thus taking the Commissioner's report for 1870, we find in that year 19,171 applica- tions for letters-patent were made, and it would appear that an average of a little over one-fourth as many were rejected for want of patenta- bility, chiefly of course for lack of novelty. Supposing all these rejec- tions to have been for just and suffi- cient cause, the system in the year | 1870 saved the public and inventors from the issue of nearly 5000 invalid patents. But it is not pretended that thr>o figures show the actual state of the case. "We cite them here as a spe- cies of starting-point and guide in estimating the weight of the various pertinent criticisms urged against the examining system and its ad- ministration. These criticisms may be divided into three classes. 1st. That patents are granted for old things, or for things previously patented to others, or for inyc.tcnt- a&Ze things. 2d. That patents are refused for things which are patentable. 3d. That unnecessary expenses and delays are occasioned in the procuring of patents. "Without denying that there is truth in each and every one of these complaints, we propose to show that from the very nature of things the evils complained of have been greatly exaggerated ; that so far as they have existed beyond that degree which it would perhaps be impossible to avoid, they are traceable to cer- tain defects of organization which Ordinary Criticisms of the Patent Office Considered. 25 may be cured ; and that they have been altogether overbalanced by the good which the system, though im- perfectly administered, has never- theless worked. Coming first to the charge that despite the examining system, pat- ents are granted for old things, or things previously patented to others, or unpaten table. In the first place it is well to re- member, both in reference to this and to other grounds of complaint, that they originate in particular in- stances, and while such instances are much bruited, from the injury real or fancied to individuals, the evidences of efficiency in the ad- ministration of the examining sys- tem, rest in official records which meet the eyes of comparatively few. The official figures which we have cited are really evidences of gen- eral efficiency of vastly more weight than any adverse evidence to be derived from the isolated experi- ences of individuals, yet the latter are more openly noised, and from this reason alone receive a degree of credit which a moment's considera- tion of the other side of the question would serve to take from them. Xor should it be forgotten how far charges of this nature may rest on mere opinion, and that, interested opinion. Take the case of a prior patentee and a present applicant for a patent, whose several inventions border very closely upon each other, all the probabilities are that if the opinions of the respective parties were taken they would prove dia- metrically opposite ; the patentee would insist on the identity or equiv- alency of the two devices, the ap- plicant would see a clear difference between the two, and instance the refusal of a patent to him as a piece of rank injustice and stupidity on the part of the Office. Each party would see and argue in his own in- terest. Nor is interest the only cause of error in this matter ; it is by no means an uncommon incident for impartial men, equally expert, to differ in their views as to the sub- stantial identity and equivalency of devices, or as to their patentability. This shows that in considering this class of complaints, much allow- ance is to be made for difference of judgment, and with the caution that the most interested judgment is not the most likely to be correct. Then again, it is a necessary fea- ture of the patent law, not so gener- ally understood as it should be, that changes or additions, be they ever so trifling apparently, in existing devices, whether patented or not, are entitled to letters-patent if they involve any degree of invention, to be determined mainly by the test of result. Many a patentee discovering that some one has patented an improve- ment upon his invention, an im- provement which no doubt to him seems more questionable or trifling than it may to others, is filled with resentment, first at the presumed 26 Ordinary Criticisms of the Patent Office Considered. poacher upon his fancied domain, and next at the Patent Office for allowing and indorsing the imagined intrusion. This is all wrong, but is loudly insisted on, in proportion to its wrongfulness. It arises mainly from the one grand fallacy, that the patent laws are intended, not for the benefit of the public at large, but for that of inventors in particu- lar. Xor does a patentee thus com- plaining usually stop to reflect, that, but for the examining system he so bitterly accuses, the subse- quent patent, in which the fancied injury lies, might have embraced not only the improvement, but also his own invention, thus working a substantial mischief, to be abated j perhaps only by litigation. It is complained that many re- jections are not for just and suffi- cient cause, and that inventors are often refused patents for that which is patentable. As to this particular complaint it is to be observed that failures to obtain a patent for that which is patentable, cannot be fair- ly charged as failure of justice until it be shown that every means which the examining system provides for obtaining his claim has been ex- hausted by the inventor in vain. This removes from the category of cases in point, those in which the inventor has not elected to exercise his right of appeal from a first or second adverse judgment. Thus the number of pertinent examples is very materially reduced. It may be safely asserted that a critical and impartial judgment Avould find those cases very few in- deed in which a just claim of inven- tion, properly presented and pr x- pense and delay of appeals, or lead to the abandonment of applications, or where they do not have one of these effects, still cause uniicco- sary expenditure of time and trouble in obtaining patents. There is truth in this complaint, and we shall have occasion to discuss the causes of the evil. But our piv>ent purpose is to point out to those who would enter upon a consideration of the examining system and its administration impartially, certain facts and reasons tending greatly to diminish the real weight of these complaints. It is first to be noted that appeals, whether justly or unjustly occa- sioned, are exceptional. It is a fact that the great majority of patents issued are allowed by the officers to whom the cases are first referred. In these instances, presuming the inventor to have performed his part of the duty by presenting his claim in proper and intelligible form, the process, expense, and time required are in general as simple, moderate, and brief as possible. It is a ques- tion which we shall have occasion to inquire into, whether the extreme simplicity and facility do not work Ordinary Criticisms of the Patent Office Considered. 27 injustice of another kind to the pub- lic and inventors ; but the alleged injustice with which we are now dealing is that of expense and delay. As lo abandonment of applica- tions, it is to he said, that in most cases it is voluntary, arising either from the applicant's ignorance of his rights, or from indifference or want of energy, in either of which cases the fault is his own. It may be ad- mitted that the mistakes of exami- ners have on rare occasions led to the involuntary abandonment of just claims. Such cases must be exceedingly few, since the fees for appeals arc so small as to be within the command of almost every one. As to difficulties being cast in the way of obtaining patents by the mistakes of officers, there is vastly more substance in this branch of the complaint than in the other. At the same time it is an evil which has been greatly exaggerated by the natural prejudices of inventors. An inventor looking at patents in the fallacious light which we have teen endeavoring to expose and controvert, and regarding himself as the only party interested in the patent laws, satisfied, too, in his own mind, with or without inquiry, that his intention is new and use- ful, and that a patent is his right, chafes at what he considers, in his particular case at least, to be :i use- less delay. The same man, having real estate to sell, would hardly ex- pect any one to purchase without taking the time to satisfy himself upon the question of title. Let him reflect then that the public, in grant- ing him a patent for his invention, does so by way of purchase, and that, unless his invention be new and useful, he has nothing to sell, the public, in providing that its offi- cers shall take necessary time and proceedings to determine these ques- tions before consummating the bar- gain, is doing simply what any busi- ness man would do in like case. It is an important fact to be re- membered too, that of the delays and expenses incurred through re- jections of applications, a very large percentage is due to the informal, imperfect, and unskilful preparation and presentation of such applica- tions by inventors or their repre- sentatives. This is a fruitful cause of difficulty of which little is heard for very obvious reasons ; it is a cause likely to be overlooked, or at least not openly acknowledged by the parties to whom it is due. It is the prevalent error in these complaints of expense and delay, that they are directed against the Patent Office indiscriminately, with- out perception of, or reference to, their true causes. Occurring in the Office, they are charged to the Office ; and to this not only the natural im- patience of inventors leads, but the conceit or the lack of candor of many of a large body of professional men. This is not to be wondered at while there is among so large a pro- 28 Actual Defects of the Patent Office and the Remedy. portion of inventors, a one-sided and partial understanding of the nature and object of the patent laws. This leads them to measure the justice and efficiency of the admin- istration of the laws solely by the ease and readiness with which patents are allowed, a test so obviously wrong, that nothing more need be said about it. That this should be the case with inventors is not perhaps to be won- dered at, but it is a somewhat astonishing and discreditable fact, that this false sentiment is echoed and encouraged by some of those whose profession it is to make and prosecute the applications of inven- tors. That an inventor should find in every unexpected lapse of time or dollar of expense incurred in the at- tainment of his wishes an instance of personal injury and a cause of complaint is not unnatural, but for a man, whose profession should be- speak a fair understanding of the law, and a cool judgment, to adopt or to counterfeit the like hot-headed, misjudging impatience, speaks little for his capacity or his candor. While thus contending that the class of complaints with which we have been dealing, have received a degree of weight and credit, to which they are by no means enti- tled, we would not be understood as denying that there have been some just grounds for such complaints. Such legitimate causes, though on examination they will be found to be infinitely fewer than may be commonly supposed, are yet more numerous than need be, and while they do not serve to point tin- ex- travagant arguments which have been based upon them, they do serve to indicate very possible improve- ments of administration. CHAPTEK VII. ACTUAL DEFECTS OF THE PRESENT ORGANIZATION OK THE PATENT OFFICE AND THE REMKDV. HAVING seen how strongly the ordinary criticism of the adminis- tration of the examining system is from the very nature of things tinctured by interest and mistaken prejudice, and how much of it is based upon opinion, not al- ways the most competent or im- partial, let us next see what evils the most impartial inquiry will be disposed to allow, either as exist- ing or as threatening, and inquire whether they are of such a nature, and so mischievous that their exist- ence or probability presents a fair argument against the wisdom of the system. The object of the system, as we have seen, is to ascertain at a time most advantageous to the public and to the inventor, that is, l>efore a patent is granted, whether the subject sought to be patented is legally paten table. The questions to be looked into may be stated generally as the Actual Defects of the Patent Office and the Remedy. 29 novelty and utility of the invention, but these embrace a variety of ques- tions, requiring for their proper solution, experienced and sound judgment. The most obvious labor which the system involves is that of research ; for the thorough and impartial per- formance of this duty, it will not be denied, an organization like that of the Patent Office is most admira- bly adapted. It is in the assumption of this duty by the public through its designated officers, that the real be- nevolence of the examining system is most strikingly apparent ; for inventors individually to make the researches necessary to determine with any degree of satisfaction whether their inventions are new or old, would in most cases be utterly impracticable, and could not be at- tempted save at enormous cost of time and money. In applying the moderate fees asked of applicants for patents to the collection and compact and systematic arrange- ment of the means for readily making these researches, and to the payment of a sufficient number of officers to make them, when it is most to the advantage of inventors that they should be made, the law proceeds upon principles of true liberality and justice. But the proper application of these researches involves judgment upon matters of diverse natures, requir- ing for their consideration different kinds of knowledge and experience. The question of novelty is not one merely of the apparent similar- ity or diversity of things in matter of form or constituent parts or oper- ation, it is not a question addressed merely to the eye or ear. The questions of novelty' and utility are naturally blended thus far, that inventions are really new inventions, entitling their inventors to be treated as producers to the public stock, only when useful in the sense of availability to some beneficial end. It therefore often becomes a mat- ter for nice discrimination and judg- ment to determine whether the points of apparent difference be- tween one device and another in- volve this utility, and so go to con- stitute patentable novelty, or wheth- er they are mere barren changes of no effect. And apart from its bearing upon the question of novelty, that of util- ity is in itself, one for the intelligent consideration of which a high de- gree of knowledge and discretion is often required. Then as the law has specified dif- ferent classes of patentable subject- matter, it frequently becomes ne- cessary to decide under which of them, a particular invention is pro- perly to be classed, and whether therefore it is or is not patentable as described and claimed by the ap- plicant. And as the first inventor only of a new and useful device is entitled to a patent, the questions to be de 30 Actual Defects of the Patent Office and the Remedy. tided in the Patent Office are not only those which in every case exist between claimants and the public, but those also which frequently arise between different claimants of the same invention. These are judicial questions requiring for their proper determination a knowledge of gen- eral and of patent law. The various questions then, which necessarily arise in the administra- tion of an examining system, require the union within the Office of differ- ent capacities and accomplishments ; there must be diligent research, there must be capacity to judge upon questions of fact touching matter in the various practical arts, and there must be capacity correctly to apply the law to the various states of fact. Applications for letters-patent are very numerous, they relate to many different branches of art, and in their consideration, as we have seen, many questions of diverse kinds arise. For the administration therefore of the examining system, an exten- sive organization is required em- bracing many officials. Now the evils likely to arise in such a state of affairs will readily suggest themselves ; they are the dangers incident to any organiza- tion embracing various classes of duties, the proper performance of some of which requires that they should concentrate in the liands of a few, of others that they should be divided among many. An improper division of labor without due regard to the capacities required for its proper performance ; the intrusting of that to many which could be more satisfactorily in- formed by a few ; the improper con- junction of opposite duties, some executory, others discretionary and judicial, some requiring chiefly time and diligence, others requiring spe- cial knowledge and capacity, and the too general dispersal of impor- tant powers. Such mischiefs as these are likely, if not carefully provided again>t. to creep into any such organization, and to cause conflicts, confusion, and lack of uniformity, exposing the whole structure to the charge of cumbrousness and inefficiency. Into such mischiefs and its con- sequent accusation has the Patent Office in fact, to some extent, justly fallen. In looking for the cause of this we may proceed upon the principle, heretofore indicated, that the labor of the Patent Office is of two kinds, one calling for intelligent research, the other for judgment. The chief requisites for the proper performance of the first class are time, diligence, and division of labor; for the second, the wants are learn- ing and capacity, and so far as pos- sible, concentration of authority. Division, so far from being a neces- sity here, is a grave objection, and for the evident reason, that in mat- ters of judgment affecting important interests the desiderata are certainty and uniformity. Actual Defects of the Patent Office and the Remedy. 31 Any one aware of the present constitution of the Patent Office will admit that these principles have not in practice been recognized to that extent which the law originally con- templated. In the early days of the Patent Office, when inventions were com- paratively few, the labor and au- thority were placed in the hands of one or two men. The demand on the Office grew more rapidly than had been anticipated, and the ne- cessity for a division of labor be- came apparent. It was a natural though a mischievous result, that with the division of labor there was also a division of authority, which necessarily resulted in a want of uni- formity in the practice of the Office. In 1855, Judge Mason, then Com- missioner of Patents, perceived the difficulties which had even then, when there were but twelve princi- pal examiners, arisen from this sub- division of independent judicial ac- tion. The judge said, in his report, " There are very grave objections to a further increase of the number of principal examiners. The system has already overgrown in that re- spect, and seems almost impera- tively to demand some modification to give it a proper harmony and uniformity of action. They (the examiners) act to a considerable extent independently of each other, and possessing very different minds and views they follow different rules of action and decision." To-day, we see the duties and the powers originally designed to be exercised by one man or at least by a few men, acting in conjunction, divided among more than a score of officers acting independently of each other, and what is worse, to a great degree independently of the really responsible power of the Office. It is here that the evil lies, and the parties injured are not merely those from whom the loudest cries of injury are heard, not those im- patient men who measure the jus- tice and efficacy of the system by the ease and readiness with which the Office may coincide with their views, and gratify their wishes, but the public, and those patentees whose interests measured by the value of their contributions to the practical arts are of great weight. To the rights or presumed rights of applicants, the power of appeal gives ample protection against the adverse action of any of the score of examiners, but the rights of the public and those of prior patentees have no such protection. Yet there can be no doubt that this defect in the organization of the Patent Office is really also of serious injury to applicants for patents. While.it does not neces- sarily tend to ultimate and perma- nent injustice, it certainly does tend to vexatious trouble and delay, in themselves grave injustice. Plainly the existence of a large number of nominally subordinate but in effect independent officers, 32 Actual Defects of the Patent Office and the Remedy. each one of them uniting in himself executive and judicial functions, and this without that direct respon- sibility which should attach to such functions officers whose actions are to a great extent uncontrolled by the authority with whom is placed the responsibility for the proper ad- ministration of the law presents an anomalous and mischievous state of affairs. Every officer may consti- tute a little court of his own, and may adopt his own maxims of law and of practice, and it will be a marvel in the history of human na- ture if the disposition to do this is not in an inverse ratio to the real capacity and responsibility of the man. This is an evil fruitful of doubt and delay, needlessly embarrassing inventors in tbe presentation and prosecution of their claims, provoc- ative of prejudice and irregular practice, and it is an evil of which in the present organization of the Office, there is constantly increas- ing danger. Fortunately, as a rule, the officers of the Patent Office have, considering the temptation and the opportunity, been signally free from dangerous assumptions of authority. Far from attributing the want of uniformity in the action of the Pat- ent Office, and the evils resulting therefrom, to the officers of that Bureau personally, we should be doing an injustice to many accom- plished gentlemen who have occu- pied, or who now occupy, the re- sponsible position of Examiner, if we failed to record our opinion that the degree of uniformity of action is, considering the circumstana-s, somewhat astonishing, and may be charged to the good sense and abil- ity of these officers as a rule, and to their observance of the instructions derived during the last few years from able heads of the Office. True there have been, and will probably continue to be, examiners with perverted ideas ; men who con- sider they are best performing their duties by presenting every obstruc- tion to the grant of patents by technical objections and trifling ac- tions ; others again, who will manu- facture patent law of their own, and others who through a spirit of display will apply theoretical dog- mas derived from collegiate cram- ming in cases where practical knowl- edge and common sense would be a much more available means of ar- riving at a correct j udgment. These officers are the exception, but the mischief they have caused, and con- tinue to cause, is great, so great as to reflect more or less odium on the whole examining corps, so that the many intelligent officers have had to bear the brunt of objec- tions attributable to the freaks of the few. Undoubtedly this division of power has worked great mischief to appli- cants for patents, and for tbe same reasons that it has worked still greater mischiefs to the public and to patentees. It creates too Actual Defects of the Patent Office and the Remedy. 33 many irresponsible judges, and unites too various functions in the same officers without due reference to the various capacity and knowl- edge required. The nature of the resulting mischief varies with the character of the officers, the ten- dency of whose errors will be in some cases to grant patents which should not be granted, in others to withhold them when they should be granted, and thus action will be- come regulated rather by personal character and whim, than by any fixed and clear principles. This will all the more be the ten- dency because the powers which these officers separately exercise are of a nature requiring for their proper exercise a union of capacities and attainments not commonly found in one mind. The questions of fact, and of mixed fact and law, con- stantly coming up for consideration, call both for scientific and practical, and for legal knowledge and judg- ment. It is in the latter branch that the examiners are most likely to be deficient, as their selection is supposed to be governed by their presumed knowledge in the various branches of the practical arts. Legal reasoning is not to be ex- pected from those not grounded in legal principles ; and there is no branch of the law admitting of more refined and subtle distinctions, requiring a more delicate and skil- ful handling than that relating to patents. "Patents," said Judge Story, "are the very metaphysics of the law." It is not one of the least alarming signs of the system as now conducted, that the applica- tion of the law to a subject so deli- cate and so important as that of in- vention, is so largely left to a number of men of whom many will have no better guide in their attempted ap- plication of judicial doctrine than the letter of Law Keports, whose spirit they cannot grasp. The necessary union of qualifica- tions is not likely to be found in each one of more than a score of men. But even suppose that this end could be accomplished, still the pres- ent organization of the Office would be defective ; for where there is not coaction there cannot be unanimity, and especially in regard to a subject where so much difference of opinion may arise among the most expert and intelligent minds. But is the evil incapable of remedy or avoidance ? The nature of the remedy is indicated by the nature of the evil ; but there may be those who will doubt the feasibility of applying the remedy. A return to the original constitution of the Of- fice is of course impossible, but surely a return to original princi- ples is not. If the duty of research, requiring time and diligence, were more completely separated than now rom that of judgment, which re- quires rather knowledge and tact, the result would be a more satisfactory performance of both duties. United in the same hands, the two duties 34 Benefits of an Examining System. become a mutual embarrassment ; they are diverse in nature, call for different kinds and degrees of men- tal capacities and attainments, and lie who may most satisfactorily per- form the one may be most unfitted for the other. For the labor of re- search, that which requires time and numbers, the present organiza- tion of the Office, with its very com- plete subdivisions, is perhaps as good as could be devised, and its efficiency would be greatly increased by the more complete separation of this class of -labor from the other. And as for what may be termed the judicial part of the duty, plainly it could be more speedily and satis- factorily performed by a few men acting in union, and having laid before them the evidence upon which they are to form their judg- ment, than it can possibly be by a much larger number of men acting independently and having with the duty of judging that also of looking up the evidence. The responsibility which attaches to judgment would in tliis way rest with a small body of men, selected for their capacity, acting in union, and not diverted from the efficient performance of their duties by labor which could as well be performed by another class of officers. Thus the practice of the Office would be more thorough, more efficient, and more uniform. It is not our purpose to suggest the legislation which may be re- quired, or the details of a mode, for working this desirable change. ' We have simply undertaken to point out wherein the real evils of the or- ganization as it now is, exist and have their origin, and the prin- ciples which it would seem should govern any endeavor to remedy and obviate such evils. The perfect feasibility of carrying out these principles will hardly be disputed, but what legislation and what changes would best carry them out, is a matter in which there may well be diversity of opinion. We have only to add that the pres- ent accomplished head of the Office, from whom we have received valu- able information, has every faith in the perfect feasibility and absolute necessity of carrying out these princi- ples, and his opportunities of judg- ing of the want of uniformity of action, together with his past able administration of the Office, point to him as the one most able to judge as to what legislation may be re- quired to correct an evil which, if permitted to grow, must eventually undermine our Patent System. CHAPTER VIII. BENEFITS OF AN EXAMINING SYSTEM. WHILE recognizing the defects in the present organization of the Pat- ent Office, and the evils which have ensued from them, and which are likely to grow unless speedily check- ed, we are not of those who discover in the past history of the organi- zation any such traces of inherent Benefits of an Examining System. 35 mischief as serve to indicate im- practicability in an examining sys- tem. On the contrary we contend that the past administration of the ex- amining system has been productive of good, entirely outweighing the evil. We have adduced certain official figures which show that in the year 1870 to a little more than 19,000 applications made, the num- ber rejected was nearly 5000. Now supposing that but one- third even of these rejections were on proper grounds, or need have been acquiesced in by the applicant, what saving of time, and money, and la- bor, that might otherwise have been thrown away in fruitless enterprise or litigation, do more than fifteen hundred rightfully rejected cases in the course of one year represent ; what value in protection to. the re- spectability and consequent value of patent property in general, is represented by the withholding in one year of fifteen hundred patents, which, granted, would not have been worth the paper on which they were printed. These are points which are apt to escape consideration, yet when brought to mind they are very sug- gestive. Then turn to another effect of the examining system, defectively ad- ministered as it may be ; we allude to what may be termed its advisory and restraining eifect. It, is the very clear interest of inventors to claim all that they imagine them- selves entitled to, and this is ex- ceedingly likely to be more than in fact they are entitled to. Claims often include with that which is new, that also which is old, and either public property or the prop- erty of some prior patentee. No can- did man, having experience in these matters, will deny that the admin- istration of the examining system has worked almost incalculable good to applicants, to patentees, and to the public, in pointing out and checking these unwitting or deliber- ate intrusions upon public or appro- priated ground, and indicating the real bounds of invention. This service has protected the interests of many a patentee, has thrown much needed light upon many an inventor's path, has tempered his too buoyant anticipations before they had led him into expenditures and enterprises, which blindly pur- sued, would have resulted in com- plications, loss, and bitter disap- pointment, and in every such sav- ing to inventors is reflected a sav- ing to the public. And there is still another benefit necessarily proceeding from exam- ination, a benefit of such import- ance that it might in itself be deem- ed an offset to many mischiefs. We refer to the necessity for clear and full specifications, and precise claims. The scrutiny which, in examina- tion, descriptions and claims un- dergo, must act as an effectual curb 36 Benefits of an Examining System. upon carelessness, duplicity, and vagueness in their preparation. An applicant must, in his own interest, be frank and precise in his state- ments, and thus a general correct- ness is engendered, the importance of which to public and private in- terests cannot be overestimated. There cannot be in American pat- ents that indefiniteness or vague generality of description and claim which is so conspicuous in many foreign patents, and which at once requires litigation to unravel, and renders litigation tedious, expen- sive, and unsatisfactory. And who can estimate the value of the Patent Office records, under the examining system, in respect to | the light which they serve to throw on the legal status and the commer- cial value of patents ? Upon every patent issued, the record of the ap- plication, of the rejections it may have met, the reasons for these re- jections, the references given to prior inventions, forms a compact com- mentary, which, while at times it may only show how singularly at fault the official judgment has been, is yet calculated to be of in- valuable service in aiding and guid- ing those who may desire to judge for themselves to what extent the value of a patent is affected by what has gone before. Nor will it escape the notice of the impartial critic that the admin- istration of the examining system, with all its imperfections and short- comings, has done very much to give to patents, as was intended, a higher legal and commercial status than they have in any other coun- try. That is certain, which can be made certain, and every aid to ar- riving at certainty is of moment. How much cf that all-important ele- ment, certainty, must be given to patent property by the means of ar- riving at it which the Office records furnish ! There can be no doubt that the moral weight, the weignt of pre- sumption which letters-patent here carry with them into the courts, and among that portion of the pub- lic who have any understanding of the Patent System, has done very much, not only to simplify and economize, but to cut off litigation by inspiring confidence on the side of right, and caution upon that of wrong. Nor has this moral power as we may term it, of patent property, de- creased, as, if the administration of the examining system were on the whole a failure, it must have done, in proportion to the marvellous in- crease in the quantity of such prop- erty existing, although it has doubtless fluctuated with the ap- parent competence and honesty, or their opposites, in the ruling powers at the Patent Office. The Patent Office is a very exten- sive institution, in which is collected a vast amount of material, rapidly augmented by constant accessions. This fact has led many to regard the organization as one which if The Examining System as Viewed from Abroad. 37 not already cumbrous and unwieldy, must speedily become so, and alarm- ing pictures have been given of the tremendous accretions of matter. It is asked how is it possible for men to conduct searches with speed and certainty amidst such records. Much has already been done to solve the question, by division of material and labor, by reducmg the records to compact and accessible shape, and by elaborate classifica- tion, amP no doubt experience will suggest further improvements in this direction. There is in truth no organization so large or complex, that a spirit of system and order cannot mould it into a simple and smoothly working unit. When the same correct principles have been applied to the arrangement of (Index which have already worked such wonders in the arrangement of material, the Patent Office will become an example of efficiency and order and uniformity of action. CHAPTER IX. THE EXAMINING SYSTEM AS VIEAVED FROM ABROAD. WHILE upon the subject of an ex- amining system it will not be out of place to see how it is regarded abroad, since the foreign views of the subject have been largely gov- erned by observance or report of the effect of the system as administered in this country. We have already had occasion to refer to some of the peculiarities and defects of the English Patent Sys- tem, which have recently attracted great attention. The subject has been much discussed both in and out of Parliament, and committees of inquiry have had before them the testimony of many prominent men, whose position, in respect to the practical arts, or whose legal attain- ment entitle their opinions to great consideration. The defects of the present English system are generally acknowledged, and seem to have divided those tak- ing part in the discussion into two parties : 1. Those who would abol- ish patents altogether, and 2. Those who, favoring patents, yet perceiv- ing the deficiency of the present laws, proposed a variety of remedial measures. Of the former parties the number is not large, nor the reasoning such as to carry any weight with it. Apart from the great cost of pat- ents, the one great deficiency of the law, admitted on all sides, lies in the practically indiscriminate and un- controlled issue of patents, which leaves bond fide inventors at the mercy, to a great extent, of unscru- pulous pirates, and opens the door to patents for merely pretended in- ventions, or for absurd and imprac- ticable schemes, and of patents with insufficient, vague, and deceitful specifications and claims. Still worse, there is no check upon the repeated patenting of similar inven- tions , and the rights of patentees are left in a cloud of darkness which 38 The Examining System as Viewed from Abroad. litigation alone can break ; this last evil being aggravated by insufficient means for trying patent causes. The various remedies proposed agree in this, that they all point to some mode of controlling the issue of patents, and the establishment of some special tribunal to deal with patent questions. As to the precise mode by which, and the time when, the ends aimed at should be at- tained, there seems to have been some difference of opinion. Of course in a discussion of this kind our examining system did not escape attention, and its merits and defects, real or supposed, were freely canvassed. It is worthy of note, however, that those who advocated the adoption in England of a system more or less analogous were men whose opinions were entitled to the greater weight, as they spoke from personal obser- vation and experience. Among these was Mr. Aston, a prominent barrister, who, after can- vassing the defects of the English law, proceeds to suggest certain remedies ; and speaking of them as being not merely speculative, but such as had been tried, thus re- marks : " Those to which I attach the most importance have been fully tried in the United States of Amer- ica, and found to work well. I mean the exercise of discrimination in the grant of patents, and what is still more important, the deposit be- fore a patent is granted of a pre- cise description of the incention and claims, given in a complete specifi- cation, which is submitted to a proper official examination before it is passed as sufficient. My own opinions upon the working of the American Patent Laws are founded upon a personal investigation of the system adopted in the United States, and from continued experience gath- ered in professional practice. My conviction is that the American sys- tem, though it has its imperfections, does work better than our#, and that because it has cured in a great meas- ure the defects under which our sys- tem is still laboring.'''' Mr. J. Howard, an inventor, man- ufacturer, and a Member of Parlia- ment, while replying to the argument of those who would abolish patents altogether, remarked, that it ap- peared to him, that most of the ar- guments that had been urged did not touch the principles of a patent law, but went rather to the defects of the existing law and its administra- tion. Mr. Howard took occasion to allude to the great and favorable im- pression which had been made on his mind by a visit to the United States Patent Office. He referred to the vital necessity for amendments in the English law, and expressed the hope that when the subject was taken in hand by the law officers of the prown, they would provide the means for a bond fide examination of all inventions before patents were granted; and also provide that the specification should be so clear that the public may knotc what really the The Examining System as Viewed from Abroad. 39 patent was granted for, and thus save the ruinous cost of leyal proceedings. Lord Romilly , Master of the llolls, while among those inclined to the abolition of patents, on the theory that they had little to do with the progress of art and civilization, sug- gested as a remedy for the present inefficient state of the laws, " the ap- pointment of a special tribunal of thoroughly efficient men, who should examine and pronounce upon all applications for patents, and grant them according as they might think the invention new and useful; or withhold them if the application was for what was trivial, worthless, injurious, or not new." Still another advocate for the adoption in England of an examin- ing system analogous to ours was found in the person of Mr. Mundella, himself a manufacturer of wide re- pute, and who has been a visitor in this country. Of course argument against the adoption of such a system was not wanting. Reference was made to re- marks proceeding, it would appear, some time ago, from Mr. Woodcroft, the accomplished Chief Clerk of the English Patent Office, whose invalu- able services in superintending the publications of that office have gain- ed him a well-earned repute. But Mr. Woodcroft's objections to an exam- ining system seem to have been singularly unhappy in the supposed facts upon which they are based. Said Mr. Woodcroft, " The Amer- icans pay about 23,000 a year for preliminary examination, and they are very much dissatisfied with it. The system of preliminary examina- tion has been tried and found want- ing. It is in operation in Prussia, but does not give satisfaction. It was tried in France, Austria, Sar- dinia, and Belgium, but being most unsatisfactory, was abandoned in each country. It is now going on in America at an enormous expense, and the CJiief Commissioner (?) wrote to me to say that it was a very inadequate system, and a very un- fair one." These remarks of Mr. Woodcroft's have been frequently quoted by op- ponents of the American examining system, and much greater impor- tance has been attached abroad to the dictum of an ex-officer of our Patent Office, who is styled a Chief Commissioner, than we should be willing to accord to it here in view of the overwhelming opinions of our best authorities in favor of an ex- amining system. But we find Mr. Woodcroft, at a more recent date, saying: "Let every man have his patent, but be- fore action is brought let the origi- nality of the claim of the invention be sifted by the most competent men of the day," a theory to which we shall have occasion to refer to here- after. That in Prussia the system should have been a failure, no one will won- der when he reads the testimony of Mr. Bessemer, who speaks from ex- perience of the honesty and benevo- 40 The Examining System as Viewed from Abroad. lence of the working of the Prussian system, in regard to- foreigners at least. Mr. Bessemer says that he did not take out a patent for his in- vention in Prussia, and explains the reason thus : " He sent his paper to Prussia in the care of Mr. Krupp, who paid him 5000 for the use of his patent. He applied in due course for a patent, and was in- formed hy the Prussian Patent Office that the invention was not new. The Prussian Patent Office grant occasional patents ; they take the fees and the drawings from British inventors in any case, and afterwards publish them for the benefit of Prussia. The Office said that Mr. Nasmyth was the inventor of the process ; Mr. Kasmyth said he was not. They next said they would give the name of the real man in a few days. Six weeks passed, and they said, ' If we don't find the name of the real man to- morrow, we will give you a patent.' A week of these to-morrows passed, after which they showed an English blue-book wiihhis own invention pub- lished in it, and they said, ' Your invention is published, so according to the law of Prussia we cannot grant you a patent.'' All the time they had been promising to grant it. The process is now worked very largely in Prussia." It is to be hoped indeed that this was an extreme case in the working of the Prussian system, but it is a well-known fact that that system is utterly arbitrary both as to end and means, which is to say that it is nec- essarily and essentially a failure. The example of Prussia, then, was a singularly unhappy and in- applicable argument against the adoption of a system of examination suited to a free country. As to the failure of examining systems in France, Austria, Sar- dinia, and Belgium, in the absence of express information as to princi- ples and details, the means adopted for carrying them out, or the extent of trial given them, it is not of course possible to examine into the causes of failure, but it would doubtless be found in the existence of some ar- bitrary features in either -end or mode. Returning to Mr. AVoodcroft's theory, it will be seen that he is not opposed to an examining system, but to our system of examination in advance of the grant ; he would grant any man a patent for any- thing, but before the patentee could exercise any rights against infringers of his patent, the latter must be sub- mitted to the scrutiny of the "most competent men of the day." If an examination is to be made, why should it not be in advance of the grant, so that the deed itself may be prima facie evidence of the paten- tee's rights? "Why should one branch of the government indiscrim- inately grant patents for another branch to scrutinize before the pat- entees can go into court, or can go before the public with any ascer- tained rights ? Why postpone lock- The Examining System as Viewed from Abroad. 41 ing the any of the legal requirements. Litiga- tion not unfrequently has the effect of showing the patentee that his patent is defective in some material particular ; and that, therefore, his right under it is not such as a court of justice can maintain and enforce. If this defect lie in total lack of novelty or utility in the invention claimed, it is of course beyond rem- edy. But it may be that the defect consists in the lack of one of these requisites in some part only of the thing claimed, or merely in the mode in which the invention is described or claimed. In its liberal dealings with the rights of patentees, whose patents are thus only partially or technically defective, our law is dis- tinguished from that of any other country. Under the English law, in a suit for infringement of a patent, proof that the patent includes more than was new and original with the pat- entee, is altogether fatal to the suit. Remedies for Defective Patents. 49 Our statutes, however, provide (section 60) that if, through inad- vertence, accident, or mistake, and without any wilful default, or intent to defraud, or mislead the public, a patentee shall have claimed in his specification to be the original and first inventor or discoverer of any material or substantial part of the thing patented, of which he was not so, he or his legal representative may yet maintain suit at law or in equity for the infringement of any part thereof which was bond fide his own, provided it shall be a material and substantial part of the thing pat- ented, and be definitely distin- guishable from the parts claimed without right, notwithstanding the specification may embrace more than that of which the patentee was the original or first inventor or dis- coverer. It will be noted that a patent which is too broad cannot under this section be partially effective, unless upon the face of the patent as it stands the old a-nd the new mat- ter be clearly distinguishable and separable, and the new matter be a material and substantial part of the thing patented. If the old and new matter are not thus definitely dis- tinguishable, the patent as it stands is altogether bad, and no suit can be maintained upon it ; but such a state of affairs is not fatal to the inventor's right : he may remedy the error in a mode which we shall allude to hereafter. The provision in favor of pat- entees in the section we have quoted is very properly coupled with the condition that in such case no costs shall be recovered in the suit, unless the proper disclaimer has been en- tered at the Patent Office before the commencement of the suit ; nor shall the patentee be entitled to the benefit of the section if he shall have un- reasonably neglected or delayed to enter said disclaimer. This proviso is to protect the pub- lic against the carelessness or bad faith of patentees, who might wit- tingly mislead and deceive the pub- lic by continuing to claim that which they themselves were aware they had no right to claim. It is the right of the public that no patent should purport to grant to the patentee more than he is fairly entitled to. The true extent of his right should distinctly appear on the face of his patent, that the public may be informed of it. When, therefore, a patentee shall have discovered that his claims in- clude more than that of which he was actual first inventor, he acts in bad faith towards the public, from whom he holds his patent, if he de- lays to rectify the error, and reduce his claim to its legitimate extent ; and much more does he act in bad faith if, with such knowledge, he attempts to enforce submission to his unjust claim by proceedings in the courts. When, therefore, a patentee dis- covers that his patent covers more than that of which he was the ac- 50 Remedies for Defective Patents Disclaimers Reissues. tual first inventor, and finds that the old matter is definitely distin- guishable and separable from the new, he is morally bound to avail himself without delay of the sec- tion of the law which permits him to remedy such an error by filing in the Patent Office what is termed a Disclaimer. This is a statement in writing, signed by the party disclaiming, attested by one or more witnesses, and recorded in the Patent Office, making disclaimer of such parts of the thing patented as the party in interest shall not choose to claim or hold by virtue of the patent. The right to file a disclaimer is not con- fined to the patentee, but his heirs or his assigns, whether of the whole or of a sectional interest in the pat- ent, have the like right. Of course, when the assignee of a sectional in- terest makes such a disclaimer, his interest only is affected by it. But it is not every patent which is too broad that can be thus cured. The remedy of disclaimer is of course applicable only to cases- where the patent specifies and claims divisible features of invention. The part re- tained and the part disclaimed must be clearly separable and distinguish- able, and the part to be retained must be a material and substantial part of the thing originally patented. When, therefore, the patent is not thus divisible, when the original claim is not of such character as to allow of a correction of the patentee's error by cutting out some clearly separable part, the removal of which will yet leave in the patent a ma- terial and substantial paten table subject of claim, the remedy of dis- claimer cannot be resorted to. I^ow there are very many patents inadvertently made too broad, in which the character of the inven- tion, or of the description or claim, would prevent any such rectifica- tion of the patent by mere excision. In such case the patentees would be without remedy, and would find themselves deprived of all right without default of their own, a state of affairs by which very many really meritorious and useful inven- tors would be irreparably injured. To obviate such mischief the law has provided the remedy of Reissue. This provision is one which has no parallel in any other patent law, and is one of those really beneficent measures which have tended to make our law so effective, because so just and liberal. Section 53 of the act provides, that "whenever any patent is in- operative or invalid, by reason of a defective or insufficient specifica- tion, or by reason of the patentee claiming as his own invention or dis- covery more than he had a right to claim as new, if the error has arisen by inadvertence, accident, or mis- take, and without any fraudulent or deceptive intention, the Commis- sioner shall, on the surrender of such patent, and the payment of the Remedies for Defective Patents Reissues. 51 duty required by law, cause a new patent for the same invention, and in accordance with the corrected specifications, to be issued to the patentee, or in the case of his death, or assignment of the whole, or any undivided part of the original patent to his executors, administrators, or assigns, for the unexpired part of the term of the original patent, the surrender of which shall take effect upon the issue of the amended pat- ent." For patents which are too broad the remedy of reissue is applicable, when the defect is such as to render the original patent altogether in- operative or invalid, because the character of the invention, or of the description and claim is such that there is no material or substantial part of the thing patented, which being truly and justly the patentee's own, is clearly separable and dis- tinguishable in the patent as it stands from that which is not the patentee's own. In other words, the remedy of reissue is applicable when that of disclaimer is not. A patent which being too broad may yet be remedied by disclaimer, is not in its original condition alto- gether inoperative and invalid, but, as \\ c, have seen, is by the terms of the law valid, for all that which being a material and substantial part of the thing patented is truly and justly the patentee's own. Upon such a patent, and for the infringement of such material and substantial part thereof as is bond fide the patentee's own, he is allowed to maintain a suit, because such part is definitely distinguishable and divisible in the patent as it stands from the parts claimed without right, which latter may, therefore, be re- moved from the patent by simple excision. But a patent which being too broad must be remedied by surrender and reissue, is inoperative and in- valid, and no suit can be maintained upon it, because the old and new matter cannot be separated in the description and claim as they stand ; no distinct part can be taken away and still leave a material and sub- stantial part of the thing patented, definitely distinguishable from the parts claimed without right. Divi- sion therefore being impossible, and since the patent as it stands, not being so divisible is wholly invalid, the only remedy is reconstruction of the description and claim, and this can be effected by way of sur- render and reissue. But it is not only as a remedy for patents, which, being too broad, can- not be cured by disclaimer, that re- issue is available. It is, in fact, a sort of universal medicine a cure for all the ills that specifications and claims are heir to. The section we have quoted makes the remedy of reissue available ichemver, through innocent inadvertence, accident, or mistake, a defective or insufficient specification renders the patent in- operative or invalid. The importance of this is appar- 52 Remedies for Defective Patents Reissues. ent when it is remembered that the consideration passing from the in- ventor to the public, for which a patent is granted, is the making and disclosure of an invention. The word disclosure argues a full and candid imparting of all the knowledge nec- essary to enable others to carry the invention into effect as fully and effectually as the inventor himself ; otherwise he has not given the con- sideration required of him, and there- fore his patent is not good. Thus, in the words of our law, "the inventor is required to file in the Patent Office a written description of his invention, and of the manner and process of making, constructing, compounding, and using the same, in such clear, full, and concise and exact terms as to enable any person skilled in the art or science to which it appertains, or with which it is most nearly connected, to make, construct, compound, and use the same." A patent, then, is not valid if essential information is omitted, or if anything be so scantily, ob- scurely, or unintelligibly stated that the whole description taken together is not sufficient to guide those skilled in the art to a correct and beneficial use of the invention. How likely such defects are to exist where an uninformed inventor has attempted to draw his own description, or has employed an incompetent attorney to do it for him, can readily be ap- prehended. The right of reissue enables a patentee so to correct or amplify his description as that it shall present a fair and faith- ful performance of his contract with the public, and so his privilege will be saved to him. Still another end, beneficial to in- ventors, is served by the power of reissue. It is essential to the faithful per- formance by the inventor of his part of the contract between the public and himself that he should clearly and candidly state what it is that he claims to be his invention, so that the public may be fully advised, from his own statement, of the ex- tent of his right ; or, as the law has it, he must "particularly point out and distinctly claim the part, im- provement, or combination, which he claims as his invention or dis- covery." What is termed the specification comprises the description and this necessary claim, which latter is to be construed with reference to the description. The courts, therefore, thus construing the claim, will al- ways, if possible, give it meaning and effect ; and meaning and effect the very fullest, consistent with the patentee's apparent right, that by the light which the description affords, they can give it. For not only will they endeavor so to construe the patent that it shall stand ; but, if possible, so that it shall be effective to protect the whole of the patentee's apparent invention. But, in doing this, they cannot of course go beyond what appears on the face of the Remedies for Defective Patents Reissues. 53 patent. Their liberality must be bounded by the actual contents of the specification. By a liberal con- struction of the whole document together they can give definite sig- nificance to an apparently obscure claim, or give wider meaning to an apparently limited claim, than if it were taken by itself its mere lan- guage would imply. But they can- not supply omissions, or construe the patent to cover that which is not directly or indirectly claimed. Now it may happen, and fre- quently does happen, that an inventor inadvertently omits such reference in his description or claim to some material and substantial part of his invention as would warrant a judicial construction of his patent as cover- ing that part. This then is a case where the patent, by reason of a de- fective and insufficient specification, is inoperative to give an exclusive right to the actual invention. In such event the patentee may sur- render his patent and take a new, or as it is termed, a reissue patent upon an amended specification, which shall distinctly specify and claim the whole of the actual invention shown, but not claimed in the original patent. Again it sometimes happens that one patent has been made to em- brace several l>licd for his original patent, and for which that patent would then have been granted had the descrip- 54 Remedies for Defective Patents Reissues. tion or claim not been defective or insufficient. The nature and object of reissues have been greatly misunderstood, and what is intended as a remedial measure in favor of the rights of inventors was, until very recently, oftentimes perverted into a means for unlawfully stretching the ap- parent scope of patents beyond the true invention, and thus imposing upon and injuring the public. This was eifected, sometimes by basing upon such rudimentary traces of important principles as might be found in a patented invention, broad and sweeping claims couched in language designed, in effect, to cover any known application of such principles to a like purpose, and sometimes by a deliberate interpola- tion in the amended specification of new matter not to be found in the original patent at all. Under careless and incompetent administrations this evil practice grew, until it had assumed alarming proportions. No sooner did a patent for some really useful invention be- come remunerative, and so draw attention, than it became the object of the greedy and unscrupulous to find some old patent worthless in itself, and purchasable for a song, but in which might be found some rude embryonic traces of the princi- ples involved in the valuable patent. Then a reissue was obtained, and all the ingenuity of language was called into play to give this reissue the apparent effect of anticipating and covering whatever was valuable in the later patent. This species of reissue became a weapon wherewith to embarrass and levy blackmail upon meritorious patentees and manufacturers, and either to cut off or compel a division of the hard- earned fruits of their ingenuity, or of their enterprise and invrsu-d capital. This had the effect too of casting a taint of suspicion upon reissues generally, to the great injury of bond fide meritorious inventors. It was found necessary to cast some restraints upon the grant of reissues, so as to put a stop to this mischievous practice. "Whereas, therefore, previous to the passage of the last act (July, 1870), reissues might be obtained by the assignees of patents without any reference to the original pat- entees whatever, it is now required by Sec. 33, that though patents may be reissued to assignees, yet the ap- plication must be made, and the new specification sworn to by the inventor or discoverer, who may reasonably be supposed to know best what his own actual inven- tion was, and to be the least likely person to make false or rash rep- resentations in regard thereto, while the doubt whether the pat- entee will prove a complacent tool, must tend greatly to check and lessen the speculation which for- merly traded in old patents, for no better purpose than the obtaining of brummagem reissues. This pro- Remedies for Defective Patents Reissues. 55 vision, however, is not applicable to patents assigned previous to July, 1870. This requirement of the law has been somewhat complained of, on the ground that it places as- signees of patents too much at the mercy of patentees, and enables the latter, should they be so disposed, to levy blackmail upon those who have already paid them for the prop- erty, the title to which it may be found necessary to better by reissue. There may be some ground for this, but the apprehended evil seems to be one which the exercise of proper discretion and care will prevent. More caution than was formerly ex- ercised by purchasers of patents will certainly be required under the present state of the law : this, how- ever, is a material advantage, for the caution required of purchasers must necessarily reflect itself in greater caution upon the part ot patentees in the mode of obtaining their patents, since imperfect patents will be found less available com- mercially. The same causes (the creation of a spirit of inquiry and discrimination as to patents) which will check the trading in patents for mere specula- tive purposes, Avill ultimately serve to check, to some extent, at least, the practices of that class of men, who, under too lax a state of the law, undeservedly nourish, and who may be termed professional pat- entees ; men who, without any merit as inventors, find in small patents a ready means of supplying their pockets, at the expense of the pub- lic. While it would be impolitic and wrong to make any distinctions as regards title to the benefit of the patent law, between inventions of different degrees of apparent im- portance, it is both politic and right to establish any measures which will be likely to raise the general standard of patents in point of legal value. This is not more to the interests of the public, than it is to the true interest of bond fide inventors. Any measure, there- fore, which, while it does not tend to work any real hardship to patentees or patent owners, yet tends to im- press upon inventors the necessity in their own interest of exercising circumspection in drawing their specifications, is beneficial, and as such a measure may this touching reissues be regarded. When the patent has been as- signed, and there are several as- signees, they must all be assenting parties to an application for a re- issue. It is also distinctly specified by the letter of the last act that "no new matter shall be introduced into the specification ; nor in case of a machine patent shall the model or drawings be amended, except each by the other." This proviso, however, is added : " But, where there is neither model nor drawing, amendments may be made, upon proof satisfactory to the Commissioner that such new mat- ter or amendment was a part of the 56 General Features of the U. S. Patent Laws. original invention, and was omitted from the specification by inadver- tence, accident, or mistake, as afore- said." The wisdom of this last provis- ion, or of the admission under any circumstances of extrinsic evidence in applications for reissue, may be doubted. Bond fide cases for the exercise of this rather sweeping dis- cretion by the Commissioner, must be comparatively very rare, and the measure might seem fairly obnox- ious to the charge of extending temptation for much misrepresenta- tion and imposition, without the likelihood of working any very ma- terial measure of justice. As a further necessary check upon the grant of reissues, the law re- quires that applications therefor shall be subject to revision and re- striction, in the same manner as original applications are. As the surrender of an original patent does not take effect until the issue of the amended patent, if ap- plication for the latter be refused and withdrawn, the original remains in force. It is provided that a reissue patent, with its corrected specifica- tion, shall have the effect and ope- ration in law, on the trial of all actions for causes thereafter arising, as though the same had been origi- nally filed in such corrected form. Of causes of action under the origi- nal patent, the surrender and reis- sue, since it involves a distinct avowal by the patentee that such original patent was inoperative and invalid, is of course an abandon- ment. CHAPTER XI. GENERAL FEATURES OF THE UNITED STATES PATENT LA\V<. IN this, our concluding chapter, we shall refer briefly to those pro- visions of our patent law which in the preceding chapter have escaped notice. It is, perhaps, one of the most striking illustrations of the differ- ence in spirit and principle between our patent law and that of Eng- land, that whereas in the latter the patentee's right rests upon his being first to disclose the invention to the public by his patent, with us the question of right is determined by reference to the date of invention. The inquiry is, who first made, not who first disclosed to the public, an invention which may be in dis- pute. Under our law an inventor does not lose his rights merely by public use or sale of his invention during a period not exceeding frn years prior to his application for a patent. It may be questioned, perhaps, whether this two years grace be not too great a stretch of liberality ; certainly, however, it allows time, which in most cases would be ample either for ascertaining practically the posi- tive and relative utility of an idea, 'or for obtaining that pecuniary aid which a poor inventor may need for General Features of the U. 5. Patent Laws Caveats. 57 the bringing of his invention into use. Time taken in conducting experi- ments with an invention is attended with the risk that the invention may be made by some other person in the meantime, or that the idea may come to the knowledge of some un- scrupulous party, who will not hesi- tate to appropriate and patent as his own, the original conception of another, if it seem likely to prove at all valuable. As applications for patent are secret ex parte transac- tions, such theft might be consum- mated without the knowledge of the true inventor, until on applying for his patent, he should find an- other party already in possession of a patent wrongfully obtained. This probability, were there no check upon it, would prevent, by making too hazardous, that expenditure of time, money, and skill, which is necessary to reduce many original inventions to the best practical shape, and would compel the premature patent- ing of half-hatched ideas. This danger the law cannot entirely obviate, but it has provided some measure of protection to inventors during the time which may be re- quired by them for conducting ex- periments to mature their ideas. Section 40 of the act provides that any citizen of the United States who has made a new invention or dis- covery, and desires further time to mature the same, may file a caveat in the secret archives of the Patent Office. Caveats Are simply brief descriptions set- ting forth the design of an invention and its distinguishing characteris- tics, accompanied by a statement that the caveator who claims the invention as his own, is engaged in taking steps to perfect it, prior to applying for letters-patent. This caveat is filed in the secret archives of the Office, and is accessible only to the officials and the caveator, or such persons as he may duly author- ize to have access to it. As a caveat refers to an avowedly uncompleted invention, while letters-patent are granted only for one which is com- plete, no proceedings are taken upon a caveat by the Office, but it re- mains for the caveator to mature his invention and file his application for a patent within one year; which time, however, may be extended from year to year by renewing the caveat. It is common to allude to caveats as affording a temporary security, thus leading many inven- tors to a mistaken impression that a caveat is a sort of temporary patent. This it is not ; a patent being a grant of the exclusive right for a certain period to make, use, and sett a completed invention, is the act of the public in consideration of the disclosure of such completed invention. A caveat is merely the caveator's own act in reference to an incomplete invention which he desires to keep secret till he has had time to mature it, in order that he may then disclose it and obtain from 58 General Features of the U. S. Patent Laws. the public the exclusive right to make, use, and sell it. A caveat, therefore, is, as its name implies, sim- ply a warning, notifying the Patent Office that the caveator has made an invention, which he intends to mature and to apply for a patent therefor within one year. The effect Which the law gives to this warning is to make it obligatory upon the Patent Office during one year after the filing or the renewal of a caveat, to grant no patent for the invention to any other claim- ant without giving the caveator op- portunity to establish his priority of right. To this end, notice is to be given to the caveator of the filing of any interfering application for a patent, without, however, informing him as to the name or whereabouts of the applicant, and he is allowed three months from the tune of such notice to complete his invention and file his application for a patent. If he fail to do this, he will be con- sidered to have waived his claim, and that of the other applicant will be considered and passed upon with- out reference to the caveat. Section 24 of the Patent Act pro- vides, that any person who has in- vented or discovered any new and useful art, machine, manufacture, or composition of matter, or any new and useful improvement there- of, not known cf used by others in this country, and not patented or described in any printed publication in this or any foreign country before his invention or discovery thereof, and not in public use or on sale for more than two years prior to his ap- plication, unless the same is proved to have been abandoned, may, upon payment of the duty required by law, and other due proceedings had, obtain a patent therefor. It is first to be noticed in this sec- tion that the term "any person" includes citizens and aliens, who in reference to the patent laws stand upon precisely the same footing. And it may be here stated that an inventor, whether citizen or al- ien, who may have previously pat- ented his invention in foreign coun- tries, does not thereby prejudice his right to a patent here, provided that the invention has not been intro- duced into public use by which is meant a use in public in the United States for more than two years prior to his application for the patent, but his patent will expire at the same time with the foreign patent, or if there are several foreign patents, then with that having the shortest term, and in no case can the term of a United States patent exceed seventeen vears from its date (sec- tion 25). Kext comes the recital of patent- able subject-matters, and then the recital of conditions essential to the obtaining of a patent, and which of course therefore are essential to the maintenance of a patent which may have been granted. These conditions are 1st. That the thing for which a Conditions to Patentability. 59 patent is sought shall not have been known or used by others in this country before the invention thereof by the claimant. The mere knowledge or use of the thing in a foreign country will not, of itself, bar or invalidate a patent, and proof of such knowledge or use, except it be in the nature of a patent, or printed publication, is not admissible against a patent excepting where it is proposed, by bringing home to the patentee a knowledge thereof, to show that his claim of invention was not a bond fide claim, and that his patent was obtained by fraudulent representa- tion. As to what knowledge or use in this country will suffice to bar or invalidate a patent, the rule would seem to be that it must not have been an entirely secret knowledge or use, but open so far as to argue ac- cessibility by the public : beyond this it matters not how limited the prior knowledge or use may have been. 2d. That the thing for which a patent is sought shall not, prior to the invention thereof by the appli- cant, have been, indented or described in any printed publication in this or any foreign country. A prior patent for, or printed publication of, a similar thing is the best possible evidence of want of novelty in an invention^ and to this end a foreign patent or printed pub- lication is equally effective with a domestic one. In either case it is a record, accessible to the public, of the prior existence of the invention claimed by the applicant or patentee as original with himself. But to bar an application or invalidate a patent, a prior patent or printed publication, whether domestic or foreign, should set forth the inven- tion so clearly and intelligibly, as to enable a competent person skilled in that branch of the arts to which the alleged invention may appertain, to make or use it. Mere vague sug- gestions of something similar will not suffice. In the absence, then, of any prior knowledge or use in this country, and of any patent or printed publi- cation in this or any foreign country, an invention is new in the eye of the law, and the inventor has an in- choate right therein which he may perfect and secure by a patent. He is not bound to apply for a patent within any specified time, nor will delay to do so, for however long a time, of itself, there being no other claimant, forfeit his right. The fetatute, however, points out two ways in which the right may be lost : 1. By public use or sale of the invention for more than two years prior to application for a patent. Public use is a use, not by the public necessarily, but any use though it may be only limited in public, so that there may be public knowledge of the thing for more than two years. As public use or sale for less than two years is not a bar to a patent, and as within such period an inven- tor misjht have made his invention 60 General Features of the V. .S'. Patent Laws. a source of profit to himself by manufacture and sale, or by allow- ing the use of it to others, it would not be right if under a patent sub- sequently obtained he could disturb or prohibit the further use of the articles thus previously sold by him, or which he had permitted to be made and used. It is therefore en- acted by Section 37 that every per- son who may have purchased of the inventor, or with his knowledge and consent may have constructed, any newly invented or discovered ma- chine, or other patentable article, prior to the application for a patent, or sold or used one so constructed, shall have the right to use, and vend to others to be used, the specific thing so made or purchased, without lia- bility therefor. The terms of this section exclude from its benefit those who may, prior to application for patent, have constructed or applied the invention, in defiance of the inventor's right, or without his assent or knowledge. 2. By abandonment. An invention may be abandoned at any time prior to application for patent. But the law does not favor and will never raise, except in the case of public use or sale for more than two years, a presumption of the abandonment of an invention. Before it will be concluded that an invention has been abandoned, there must be some clearly proven act or expression on the part of the in- ventor, unmistakably indicating his intention not to claim any exclusive right in the invention, but to allow it to become public property, for an invention can be abandoned only to the public at large. As a rule, therefore, a valid pat- ent may be obtained for any im- provement which has not been known or used by others in this country, nor been patented or de- scribed in any printed publication in this or any foreign country before the date of its invention or dis- covery by the party claiming it as his own, unless he has allowed it to be in public use or on sale for more than two years before his application for a patent, or has at any time be- fore such application by a voluntary and deliberate act abandoned it to the public. Should the claim of an applicant for a patent be rejected, or should a patent granted be assailed in liti- gation, on the ground of a prior foreign patent or description in a foreign printed publication, if the applicant or patentee can establish by competent proof that his inven- tion preceded the date of such prior foreign patent or publication, a pat- ent will be granted him if he be an applicant ; or, if he be a patentee, his patent will be sustained. And, in the case of an applicant for a patent, ex parte evidence in such case suffices to establish his priority of right. Such evidence is also competent to overcome the rejection of a claim for a patent on the ground of de- scription in a printed publication in General Features of the U. S. Patent Laws Interferences. 61 this country, or a rejection on the ground that the invention is already in public use or on sale, unless it shall appear that such public use or sale has been for more than two years prior to the application for a patent. But if application for a patent be made for something already pat- ented in this country, or which an- other party is at the same time seeking to patent here, it may be necessary in either case to try the question of priority of invention in the Office. This is done by means of what is termed an interference a judicial proceeding in which the rival claimants of the same inven- tion are allowed to present testi- mony in support of .their respective claims, the testimony being taken in the same mode as in a cause in equity, and each party having the right to be present at the examina- tion of, and to cross-examine, his op- ponent's witnesses. This departure from the general rule, which makes applications for patents altogether c.i- jxirtc proceedings, is necessitated by the circumstances of the case. The Patent Office can lawfully grant a patent only to the true and first inventor, and can lawfully grant a *<:<<,, .><; with a claim to something claimed or clearly shown in any patent or patents previously granted. This power may be very benefi- cially used to check what was at one time a practice as common as it is mischievous, that of reissu- ing patents for the sole purpose of so extending their chums a.s to cover some feature of value in pat- ents granted subsequently to those sought to be reissued. In the case of an interference between an application for a patent and a patent granted, the power of the Commissioner extends only to granting another patent to the ap- plicant, should he appear to have been the actual first and true inven- tor. He cannot recall or cancel the prior patent. His office is in its nature minis- terial, and concerns only the grant- ing of patents ; and his discretion- ary, or, what may be termed his quasi-judicial powers, therefore, are confined to the consideration and determination of such questions only as concern the granting of patents. His duty is to grant a patent to whomsoever may appear to be the true and first inventor of a patent- able subject-matter, and justly en- titled under the law to receive a General Features of the U. S. Patent Laws Priority. 65 patent therefor. In the execution of this duty it is necessary for him to consider and decide disputed questions of priority of invention ; but with that and the grant or re- fusal of a patent, in accordance with his determination, his duty and power end. The power of 'annulling or de- creeing the invalidity of patents, or other public grants, is one of the chancery powers of the courts of the United States. Consequently where, through the issue of an interference in the Pat- ent Office, or through accident, there are two or more patents for the same thing, of which only one of course can be valid, the invalidity of the others can be authoritatively as- certained and decreed only by a court of the United States having jurisdiction of such questions. Under Section 58 of the Patent Act : u Whe never there shall be in- terfering patents, any person inter- ested in any one of such interfering patents, or in the working of the in- vention claimed under either of such patents, may have relief against the interfering patentee, and all parties interested under him, by suit in equity against the owners of the interfering patent ; and the court having cognizance thereof, on notice to adverse parties and other due proceedings had, may adjudge and declare eitlier of the patents void in whole or in part, or inoperative, or invalid hi any particular part of the United States according to the in- terest of the parties in the patent or the invention patented. But no such judgment or adjudication shall affect the right of any person ex- cept the parties to the suit and those deriving title under them subsequent to the rendition of such judgment." In the case of an interference in the Patent Office between an ap- plication and a prior patent, should the applicant be adjudged the prior inventor, the only measure of justice which the Commissioner has power to perform is, by grant- ing a patent to the applicant, to put him in a position to avail himself, should he desire to do so, of the remedy presented by this section against the prior patentee. The point to be adjudged in a case of interference is "priority of invention." The general rule is that he is in the eye of the law the first inventor who has first perfected and adapted the invention to use. But this rule is subject to the qualification that he who first in- vents, i. e., mentally originates, shall have the prior right, if he were using reasonable diligence in adapt- ing and perfecting the invention. Thus it is made by the statute a de- fence against a patent, that the pat- entee had surreptitiously or unjustly obtained the patent for that which was in fact invented by another, who was using reasonable diligence in adapting and perfecting the same. It has been held that the words 66 General Features of the U. S. Patent Laws Priority. "surreptitiously," or "unjustly," as here used, do not necessarily im- ply that bad faith on the part of the patentee must be shown to make this defence available. But it will be deemed that a patent has been wrongfully obtained, when it is for something which was in fact first invented by another than the pat- entee, if the prior inventor was at the time using reasonable diligence in adapting and perfecting the in- vention. This reconciles the reference in our patent law of the doctrine that "he who is prior in time has the better right" to the time of the making of an invention, with the general maxim that "the laws serve the diligent, and not the sloth- ful. " A right of priority must be perfected by diligence. The courts will not allow the plea of "prior invention" to overcome the title of a patentee whose patent was obtained in good faith, unless it be shown that the alleged prior inventor had actually reduced his conception to practice in a practi- cally useful and operative form, or that being the first to invent, he was, at the time the patentee obtained his patent, exercising reasonable dili- gence to adapt and perfect the in- vention. A mere prior conception of an idea, ending in experiment, and never reduced to that practical shape in which alone it can be use- ful to the public, and can attract public attention, will not suffice to destroy the title of a patentee, who being himself a bowi fide original inventor, has reduced the invention to successful practice, and published it by obtaining his patent. By these judicially established principles the Patent Office is guided in determining the questions of " priority of invention," in capes of interference. If the interference be between the claim of an applicant and that of a patentee, iheprimnfiiric presump- tion is in favor of the latter, and the burden is upon the applicant to show that he was the first inventor, and also that he had either actually reduced the invention to a practi- cally operative shape before the in- terfering patent was obtained, or that at the time it was obtained, he was exercising reasonable diligence to bring it into such shape ; and, furthermore, it must appear that the applicant has not unnecessarily de- layed bringing his claim, but that he has been reasonably diligent, as well in bringing his application as in perfecting his invention. If he cannot show this, the first patent will not be disturbed by the grant ' of a second Where the interference is between independent applicants for patents, there is not that strength of pre- sumption in favor of either party which the possession of a patent, a vested right, creates : still there is a presumption in favor of the earli- est applicant, on the reasonable prin- ciple that, in the absence of proof to General Features of the U. S. Patent Laws Diligence. 67 the contrary, the first to seek the benefit of the law must be presumed to have the prior and better right. This presumption goes no further than to require that the later appli- cant must first prove a date for his invention anterior to the application of his opponent, before the latter need offer proof as to the date of his invention other than that which his application affords. The general principles applied to the decision of priority, as between applicants for patents, are the same as in other cases. He will, as a rule, be held the first inventor, entitled to the benefit of the law, who being bond fide an inventor first reduced the invention to a practical form beneficial to the public. As to the evidence which will suffice to prove invention, the rule would seem to" be that the idea must have been so far reduced to practice as to have been illustrated or de- scribed in a mode sufficient to en- able a person skilled in the art to which the invention may refer, to make or practice it, without calling for the exercise on his part of more than the ordinary skill of his trade. Less than this will not evidence a matured, and therefore patentable, invention ; such an invention as the law will protect. It will be seen that the question of "diligence" has a most material bearing upon that of "priority of right in law," and this matter of diligence enters not only into the reduction of an invention to prac- tice, but into the making and prose- cution of application for a patent, wherever there is a question of right between independent inventors. Es- pecially is this the case where one or other of the disputants is in pos- session of a patent obtained in good faith : the right of such a patentee will not be disturbed in favor of a slothful inventor, prior in point of conception, but who, after the grant of the patent to his competitor, of which as matter of public record he in common with the rest of the pub- lic is presumed to have knowledge, has unnecessarily delayed perfecting and adapting the invention to use, and presenting his claim. It has been found necessary to spur the diligence of applicants for patents even in cases entirely ex parte by providing (Sec. 32) that all applications for patents shall be com- pleted and prepared for examination within two years after the filing of the petition, and in default thereof, or upon failure of the applicant to prosecute the same within two years after any action therein, of which no- tice shall have been given to the ap- plicant, they shall be regarded as abandoned by the parties thereto, unless it be shown to the satisfac- tion of the Commissioner that such delay was unavoidable. If an applicant for a patent is not satisfied with the justice of a de- cision of the Commissioner of Pat- ents, refusing him a patent, he may appeal to the Supreme Court of the 68 General Features of the U. S. Patent Laws Appeals. District of Columbia, which may reverse the decision of the Commis- sioner. By the decision of the court, duly certified to and recorded in the Patent Office, the further proceed- ings in that office are to be regula- ted, and if no reasons are found for refusing a patent, beyond those raised and adjudicated in the ap- peal, the Commissioner is bound by a decision favorable to the appli- cant to issue a patent. But as the court is to consider the case, on the evidence produced before tlie Commis- sioner, and its decision is confined to il\A points raised in the appeal, if the Commissioner after such de- cision finds good reasons, not in- volved in the appeal, or depending upon new evidence not formerly be- fore him, for still withholding the patent, it is within his discretionary power so to do. In other words, the decision of the court upon appeal, if favorable to the applicant, is not that the Commissioner shall issue a patent, but that he shall not with hold it upon the grounds raised in the appeal ; and it might seem that as often as the Commissioner may refuse a patent upon new grounds, the applicant may appeal to the court. The right of appeal to the Supreme Court of the District of Columbia does not extend to parties in interference. The remedy of an inventor against what he may consider an unjust re- fusal of a patent does not end even here. Section 52 of the act provides that when an application for a pat- ent is refused for am/ reason what- ever, either by the Commissioner, or by the Supreme Court of the Dis- trict of Columbia on appeal from the Commissioner, the applicant may have remedy by bill in equity in a court of the United States having cognizance of such cases under the patent law ; and the court upon notice to adverse parties, and other due proceedings had, may adjudge that such applicant is entitled, ac- cording to law, to receive a patent for his invention, as specified in his claim, or for any part thereof, as the facts in the case may appear. This remedy by bill in equity is applicable to all cases where a pat- ent may have been refused. If the refusal has been on account of an adverse decision by the Com- missioner, in a case of interference, the party in whose favor the Com- missioner's decision was rendered is entitled to notice, and to become a party in the proceedings upon the bill. Where there is no opposing party a copy of the bill is to be served on the Commissioner. Proceedings under this section are not in the nature of an appeal, and are not to be governed by the evi- dence in the case before the Com- missioner, but they are original proceedings, in which such original evidence may be adduced as shall be considered essential to arriving at a just decision. An adjudication in favor of the applicant authorizes the Commis- Remedies for Infringement. sioner to issue such patent as it shall be decided the applicant is en- titled to, upon the applicant filing in the Patent Office a copy of the adjudication, and otherwise com- plying with the provisions of the law. It only remains now briefly to in- quire as to the modes in which a rem- edy may be had for the infringement of a patent. There are two ends which it is generally essential to the interests of a patentee he should have the means of accomplishing by resort to the courts, a remedy for injury from past infringement, and the prevention of infringement in the future. Damages for infringement may be had by action at law in the Circuit Courts of the United States, or those District Courts exercising cir- cuit court jurisdiction. And as a check upon deliberate, wrongful in- fringements, the courts are empow- ered, ; ' whenever in any such ac- tion a verdict is rendered for the plaintiff, to enter judgment thereon for any sum above the amount found by the verdict as the actual damages sustained, according to the circumstances of the case, not exceeding three times the amount of such verdict, together with the costs. But this remedy at law is generally quite inadequate to the needs of patentees, since it does not prevent further infringement by thu party sued, and for each new act of infringement fresh suit must be brought. For the purpose of pre- venting further infringement, it is necessary to resort to proceedings in equity, which may be brought in the same courts. Section 55 of the law empowers the courts, upon bill in equity filed by any party aggrieved, to grant injunctions to prevent the violation of any right secured by patent, on such terms as the court may deem reasonable." Injunctions are either temporary or perpetual. A temporary injunc- tion is one granted before a final hearing of the cause, and may be granted at the discretion of the court at any time after the filing of the bill, upon moticn, of which rea- sonable previous notice shall have been given to the defendant, accom- panied by copies of the affidavits to be read in support of the motion. A temporary injunction prohibits continuance of the infringement complained of in the bill until the question of the complainant's right under his patent shall have been tried, or until further order of the court. It is a summary proceed- ing, in order to protect a patentee against the irreparable injury that might ensue to him by an unchecked continuance of infringement during the time necessary for bringing a cause to final hearing. But as it is a proceeding tending to bind the rights of a defendant, before a fair and full trial has been had, and one which may work great, and, as it may prove, unwar- TO General Features of the U. S. Patent Laws. ranted injury to the party enjoined, the courts exercise the power with great caution, and only where there has been exclusive possession under the patent for some years, with ac- quiescence of the public in the pat- entee's right, or where the patent has been previously judicially sustained after full trial at law or in equity ; nor will the power be exercised if the defendant, by affidavits, rebut- ting and overbearing the weight of those of the complainant, can throw reasonable doubt, on grounds not theretofore adjudicated, upon the patentee's title, or can indicate that he is not a mere wrongdoer, but has a good defence against the action. The court in granting a temporary injunction, may couple with the grant such conditions, either on one or on both sides, as under the cir- cumstances of the case may seem reasonable ; or, it may allow the defendant to give security to keep an account of profits from the use of the invention,^ and this it will do, where it appears from the circum- stances that in this way the interests of the patentee will be substantially protected, while an injunction would work disproportionate mischief to the defendant. A temporary injunc- tion will not be granted where it appears that the patentee has not been diligent in seeking- his remedy, but has allowed infringement to con- tinue for a considerable period of time without taking steps to pre- vent it. A temporary injunction may be dissolved at any time upon motion of the party enjoined, made after reasonable previous notice to the complainant, and supported by affi- davits showing good and sufficient reason. A perpetual injunction is one granted upon a decree in favor of the patentee after final hearing upon proofs and argument in equity, or after a judgment in favor of the patentee in a trial at law, and its effect is to enjoin the defendant from infringement during the term of the patent. Formerly it was the practice here, as it still is in England, for the court in equity, when an application for an injunction raised disputed questions of fact affecting the patentee's title, to order a trial at law, that these questions of fact might be passed upon by a jury ; but here, since pat- ent causes, whether in law or in equity, are cognizable in the same court, and since it is competent for the court in equity to consider- and determine all disputed points in such causes, whether of fact or of law, generally patent cases are now so tried and determined, upon proofs taken after the course in equity, be- fore an examiner appointed by the court. The questions of fact arising in patent causes are generally of such a nature that they may be deter- mined much more speedily, readily, and satisfactorily by a judge than by a jury, and under the present law all the remedies which proceed- Remedies for Infringement Conclusion. ings at law might afford a patentee for infringement of his right, he can obtain by proceedings in equity, while the latter will also afford him further remedy, very much more complete and beneficial than he could possibly obtain by proceed- ings at law. "Upon a decree being rendered for infringement, the complainant shall be entitled to recover, in ail.ilition to the profits to be ac- counted for by the defendant, the damages the complainant has sus- tained thereby, and the court shall assess the same, or cause the same to he assessed under its direction,- and the court shall have the same powers to increase the same, in its discretion, that are given by this act to increase the damages found by verdict in actions upon the case." (Sec. 55.) It is not necessary to sustain an action for infringement, that the whole of the invention patented should have been infringed, but remedy may be had for the infringe- ment of any material or substantial part thereof claimed. Actions for infringement may be brought in the name of the owner or joint owners of the legal title to the patent throughout the whole of the United States, or within the particular part or portion of the United States in which the action is brought. A licensee cannot bring such an action, except he join with him the party or parties in whom the legal title to the patent is vested within the territory over which the court wherein the action is brought has jurisdiction. Actions for in- fringement must be brought during the term of the patent, or within six years after its expiry. CONCLUSION. ^.t this point we close our brief summary of the general features of the Patent Laws of the United States, and with it the treatise. As far as was possible, we have ranged the subjects together in such a way as to produce a connected review of the entire ground. Of course, there are many special mat- ters of law and doctrine respecting patents which have not been touched upon, specialties out of place in a pamphlet avowedly devoted to a grouping of information of a merely general character. As to those subjects which are treated more at length, we venture to express a hope that our endeavors plainly and concisely to illustrate the principles governing property in invention, will not be altogether in- effectual in throwing light upon matters which have heretofore, by so many minds, been but partially and obscurely understood.

And an alien shall have the privilege herein granted, if he shall have resided in the United States one year next preceding the filing of his caveat, and made oath of his intention to become a citizen. SEC. 41. And be it further enacted, That whenever on exami- nation, any claim for a patent is rejected for any reason what- ever, the Commissioner shall notify the applicant thereof, giving him briefly the reasons for such rejection, together with such information and references as may be useful in judging of the propriety of renewing his application or of altering his specifi- cation ; and if, after receiving such notice, the applicant shall persist in his claim for a patent, with or without altering his specifications, the Commissioner shall order a re-examination of the case. SEC. 42. And be it further enacted, That whenever an appli- cation is made for a patent which, in the opinion of the Com- missioner, would interfere with any pending application, or with any unexpired patent, he shall give notice thereof to the appli- cants, or applicant and patentee, as the case may be, and shall direct the primary examiner to proceed to determine the ques- 85 tion of priority of invention. And the Commissioner may issue a patent to the party who shall be adjudged the prior inventor, unless the adverse party shall appeal from the decision of the primary examiner, or of the board of examiners-in-chief, as the case may be, within such time, not less than twenty days, as the Commissioner shall prescribe. SEC. 43. And be it further enacted, That the Commissioner may establish rules for taking affidavits and depositions required in cases pending in the Patent Office, and such affidavits and de- positions may be taken before any officer authorized by law to take depositions to be used in the courts of the United States, or of the State where the officer resides.

SEC. 45. And be it further enacted, That every witness duly subpoenaed and in attendance shall be allowed the same fees as are allowed to witnesses attending the courts of the United States, but no witness shall be required to attend at any place more than forty miles from the place where the subpoena is served upon him, nor be deemed guilty of contempt for disobey- ing such subpoena, unless his fees and travelling expenses in going to, returning from, and one day's attendance at the place of exam- ination, are paid or tendered him at the time of the service of the subpoena ; nor for refusing to disclose any secret invention or discovery made or owned by himself. SEC. 46. And be it further enacted, That every applicant for a patent or the reissue of a patent, any of the claims of which 86 have been twice rejected, and every party to an interference, may appeal from the decision of the primary examiner, or of the examiner in charge of interference, in such case, to the board of examiners-in-chief, having once paid the fee for such appeal provided by law. SEC. 47.

SEC. 50. And be it further enacted, That it shall be the duty of said court, on petition, to hear and determine such appeal, and to revise the decision appealed from in a summary way, on the evidence produced before the Commissioner, at such early and convenient time as the court may appoint, notifying the Commissioner of the time and place of hearing ; and the re- vision shall be confined to the points set forth in the reasons of appeal. And after hearing the case, the court shall return to the Commissioner a certificate of its proceedings and decision, which shall be entered of record in the Patent Office, and govern the further proceedings in the case. But no opinion or decision of the court in any such case shall preclude any person inter- ested from the right to contest the validity of such patent in any court wherein the same may be called in question. SEC. 51. And be it further enacted, That on receiving notice of the time and place of hearing such appeal, the Commissioner shall notify all parties who appear to be interested therein, in such manner as the court may prescribe. The party appealing shall lay before the court certified copies of all the original pa- pers and evidence in the case, and the Commissioner shall fur- 87 nish it with the grounds of his decision, fully set forth in writ- ing, touching all the points involved by the reasons of appeal. And at the request of any party interested, or of the court, the Commissioner and the examiners may be examined under oath, in explanation of the principles of the machine or other thing for which a patent is demanded. SEC. 52. And be it further enacted, That whenever a patent on application is refused, for any reason whatever, either by the Commissioner or by the Supreme Court of the District of Co- lumbia upon appeal from the Commissioner, the applicant may have remedy by bill in equity ; and the court having cognizance thereof, on notice to adverse parties and other due proceedings had, may adjudge that such applicant is entitled, according to law, to receive a patent for his invention, as specified in his claim, or for any part thereof, as the facts in the case may ap- pear. And such adjudication, if it be in favor of the right of the applicant, shall authorize the Commissioner to issue such patent, on the applicant filing in the Patent Office a copy of the adjudication, and otherwise complying with the requisitions of law. And in all cases where there is no opposing party a copy of the bill shall be served on the Commissioner, and all the ex- penses of the proceeding shall be paid by the applicant, whether the final decision is in his favor or not. SEC. 53. And be it further enacted. That whenever any patent is inoperative or invalid, by reason of a defective or insufficient specification, or by reason of the patentee claiming as his own invention or discovery more than he had a right to claim as new, if the error has arisen by inadvertence, accident, or mis- take, and without any fraudulent or deceptive intention, the Commissioner shall, on the surrender of such patent, and the payment of the duty required by law, cause a new patent for the same invention, and in accordance with the corrected speci- fications, to be issued to the patentee, or, in the case of his death or assignment of the whole or any undivided part of the original patent, to his executors, administrators, or assigns, for the unexpired part of the term of the original patent the sur- render of which shall take effect upon the issue of the amended patent ; and the Commissioner may, in his discretion, cause several patents to be issued for distinct and separate parts of the thing patented, upon demand of the applicant, and upon pay- 88 ment of the required fee for a reissue for each of such reissued letters-patent. And the specification and claim in every such case shall be subject to revision and restriction, in the same manner as original applications are. And the patent so reissued, together with the corrected specification, shall have the effect and operation in law, on the trial of all actions for causes there- after arising, as though the same had been originally filed in such corrected form; but no new matter shall be introduced into the specification, nor in case of a machine patent shall the model or drawings be amended except each by the other, but when there is neither model nor drawing, amendments may be made upon proof satisfactory to the Commissioner that such new matter or amendment was a part of the original invention, and was omitted from the specification by inadvertence, acci- dent, or mistake, as aforesaid. SEC. 54. And be it further enacted, That whenever, through inadvertence, accident, or mistake, and without any fraudulent or deceptive intention a patentee has claimed more than that of which he was the original or first inventor or discoverer, his patent shall be valid for all that part which is truly and justly his own, provided the same is a material or substantial part of the thing patented ; and any such patentee, his heirs or assigns, whether of the whole or any sectional interest therein, may, on payment of the duty required by law, make disclaimer of such parts of the thing patented as he shall not choose to claim or to hold by virtue of the patent or assignment, stating therein the extent of his interest in such patent ; said disclaimer shall be in writing, attested by one or more witnesses, and recorded in the Patent Office, and it shall thereafter be considered as part of the original specification to the extent of the interest pos- sessed by the claimant and by those claiming under him after the record thereof. But no such disclaimer shall affect any action pending at the time of its being filed, except so far as may relate to the question of unreasonable neglect or delay in filing it. SEC. 55. And be it further enacted, That all actions, suits, controversies, and cases arising under the patent laws of the United States shall be originally cognizable, as well in equity as at law, by the Circuit Courts of the United States, or any District Court having the powers and jurisdiction of a Circuit 89 Court, or by the Supreme Court of the District of Columbia or of any Territory ; and the court shall have power, upon bill in equity, filed by any party aggrieved, to grant injunctions ac- cording to the course and principles of courts of equity, to pre- vent the violation of any right secured by patent, on such terms as the court may deem reasonable ; and upon a decree being ren- dered in Any .such case for an infringement, the complainant shall be entitled to recover in addition to the profits to be ac- counted for by the defendant, the damages the complainant has sustained thereby, and the court shall assess the same, or cause the same to be assessed under its direction, and the court shall have the same powers to increase the same, in its discretion, that are given by said act to increase the damages found by ver- dicts in actions upon thease; but all actions shall be brought during the term for which the letters-patent shall be granted or extended, or within .six years after the expiration thereof. SEC. 56. And be it further enacted, That a writ of error or ap- peal to the Supreme Court of the United States shall lie from all judgments and decrees of any Circuit Court, or of any Dis- trict Court exercising the jurisdiction of a Circuit Court, or of the Supreme Court of the District of Columbia, or of any Ter- ritory, in any action, suit, controversy, or case, at law or in equity, touching patent rights, in the same manner and under the same circumstances as in other judgments and decrees of such Circuit Courts, without regard to sum -or value in contro- versy. SEC. 57. And be it further enacted, That written or printed copies of any records, books, papers, or drawings, belonging to the Patent Office, and of letters-patent under the signature of the Commissioner, or acting commissioner, with the seal of office affixed, shall be competent evidence in all cases wherein the originals could be evidence, and any person making appli- cation therefor, and paying the fee required by law, shall have certified copies thereof. And copies of the specifications and drawings of foreign letters-patent, of record in the Patent Office, certified in like manner, shall be prima facie evidence of the fact of the granting of such 'foreign letters-patent, and of the date and contents thereof. SEC. 58. And be it further enacted, That whenever there shall be interfering patents, any person interested in any one of such 12 90 interfering patents, or in the working of the invention claimed under either of such patents, may have relief against the inter- fering patentee and all parties interested under him hy suit in equity against the owners of the interfering patent; and the court having cognizance thereof, as hereinbefore provided, on notice to adverse parties, and other due proceedings had, accord- ing to the course of equity, may adjudge and declare either of the patents void in whole or in part, or inoperative, or invalid in any particular part of the United States, according to the in- terest of the parties in the patent or the invention patented. But no such judgment or adjudication shall affect the rights of any person, except the parties to the suit and those deriving title under them subsequent to the rendition of such judgment. SEC. 59. And be it further enacted, That damages for the in- fringement of any patent may be recovered by action on the case in any Circuit Court of the United States, or District Court exercising the jurisdiction of a Circuit Court, or in the Supreme Court of the District of Columbia, or of any Terri- tory, in the name of the party interested, either as patentee, as- signee, or grantee. And whenever in any such action a verdict shall be rendered for the plaintiff, the Court may enter judg- ment thereon for, any sum above the amount found by the ver- dict as the actual damages sustained, according to the circum- stances of the case, not exceeding three times the amount of such verdict, together with the costs. SEC. 60. And be it further enacted, That whenever, through inadvertence, accident, or mistake, and without any wilful de- fault or intent to defraud or mislead the public, a patentee shall have, in his specification, claimed to be the original and first inventor or discoverer of any material or substantial part of the thing patented, of which he was not the original and first in- ventor or discoverer, as aforesaid, every such patentee, his ex- ecutors, administrators, and assigns, whether of the whole or any sectional interest in the patent, may maintain a suit at law or in equity, for the infringement of any part thereof, which was bon&Jide his own, provided it shall be a material and sub- stantial part of the thing patented, and be definitely distinguish- able from the parts so claimed, without right as aforesaid, not- withstanding the specifications may embrace more than that of which the patentee was the original or first inventor or dis- 91 coverer. But in every such case in which a judgment or decree shall be rendered for the plaintiff, no costs shall be recovered, unless the proper disclaimer has been entered at the Patent Office before the commencement of the suit , nor shall he be en- titled to the benefits of this section, if he shall have unreason- ably neglected or delayed to enter said disclaimer. SEC. 61. And be it further enacted, That in any action for in- fringement the defendant may plead the general issue, and having given notice in writing to the plaintiff or his attorney, thirty days before, may prove, on trial, any one or more of the following special "matters: First. That for the purpose of deceiving the public the de- scription and specification filed by the patentee in the Patent Office was made to contain less than the whole truth relative to his invention or discovery, or more than is necessary to pro- duce the desired effect ; or, Second. That he had surreptitiously or unjustly obtained the patent for that which was in fact invented by another, who was using reasonable diligence in adapting and perfecting the same ; or, Third. That it had been patented or described in some printed publication prior to his supposed invention or discovery thereof; or, Fourth. That he was not the original and first inventor or discoverer of any material and substantial part of the thing patented ; or, Fifth. That it had been in public use or on sale in this country, for more than two years before his application for a patent, or had been abandoned to the public. And in notices as to proof of previous invention, knowledge, or use of the thing patented, the defendant shall state the names of patentees and the dates of their patents, and when granted, and the names and residences of the persons alleged to have in- vented, or to have had the prior knowledge of the thing pat- ented, and where and by whom it had been used ; and if any one or more of the special matters alleged shall be found for the defendant, judgment shall be rendered for him, with costs. And the like defences may be pleaded in any suit in equity for relief against an alleged infringement; and proofs of the same may be given upon like notice in the answer of the defendant, and with the like effect. 92 SECT. C2. And be it further enacted, That whenever it shall appear that the patentee, at the time of making his application for the patent, believed himself to be the original and first in- ventor or discoverer of the thing patented, the same shall not be held to be void on account of the invention or discovery, or any part thereof, having been known or used in a foreign country, before his invention or discovery thereof, if it had not been patented, or described in a printed publication.
