Appellant, complainant below, unsuccessfully sought to enjoin appellees from infringing letters patent, No. 613,844, on a bogus-coin detector for coin-operated vending machines. The letters were granted November 8, 1898, to the Mills Novelty Company, assignee of the inventor. While that company was the owner, the only practical use to which the detectors were put was to guard gambling machines, made and controlled by the company, from being operated by means of bogus coins. On December 8, 1899, the company assigned the patent to appellant, and, as a part of the same transaction, took from him a license to make and use the device. No one else used it by authority. Appellees, without license, applied it to gambling machines of their make. This suit was begun about a month after the assignment. The circumstances surrounding the assignment and attending the conduct of this litigation warranted the trial court in finding that the equities of the case should be determined as if the Mills Novelty Company had been complainant.
The defenses are two: That the patent is void for want of utility; and that, even if it is found not to be void, complainant has no
In support of their first contention, appellees cite Device Co. v. Lloyd (C. C.) 40 Fed. 89, 5 L. R. A. 784; Novelty Co. v. Dworzek (C. C.) 80 Fed. 902; Schultze v. Holtz (C. C.) 82 Fed. 448; Rickard v. Du Bon, 43 C. C. A. 360, 103 Fed. 868; and Mahler v. Animarium Co., 49 C. C. A. 431, 111 Fed. 530. In the Rickard Case, involving a process for spotting tobacco leaves, and in the Mahler Case, concerning a cure-all device, the clear purpose and the sole use of the respective inventions were found to be to deceive and defraud the public. In the Schultze Case, the fact that the invention had been used solely for gambling and could not be put to any other use was held to avoid the patent. In the two other cases, applications for injunctions were denied on showings that the devices had been used only for gambling purposes. But the court, in each case, went further and held the device to be wanting in utility, saying: “The patent has been very recently issued, and it is possible that a useful application may yet be found for it; but, as the case now stands, the only use to which the invention has been put being for gambling purposes, I must hold that it is not a useful device within the meaning of the patent law.” It may be doubted whether, in the latter holding, useableness (utility) and use (application) were not confounded; but, at all events, the courts in those cases came to the same end as the others, in deciding that the respective patents were not for useful devices within the meaning of the patent law.
With regard to the defense of no utility (available equally at law and in equity), we hold that the true inquiry is, Was the government improvident in making the grant? Does the opposing evidence, the grant itself being prima facie proof of utility, go to the extent of establishing not merely that the device has been used for pernicious purposes, but that it is incapable of serving any beneficial end? As the just criterion, we approve and adopt Mr. Walker’s conclusion (section 82 [3d Ed.]), with the additions to his text which we note by parentheses :
“An important question, relevant to utility in this aspect, may hereafter arise and call for judicial decision. It is perhaps true, for example, that the invention of Colt’s revolver was injurious to the morals, and injurious' to the health, and injurious to the good order of society. That instrument of death may have heen injurious to morals, in tending to tempt and to promote the gratification of private revenge. It may have heen injurious to health, in that it is very liable to accidental discharge, and thereby to cause wounds, and even homicide. It may also have heen injurious to good order, especially in the newer parts of the country, because it facilitates and increases private warfare among frontiersmen. On the other hand, the revolver, by furnishing a ready means of self-defense, may sometimes have promoted morals -and health and good order. By what test, therefore, is utility to be determined in such cases? Is it to be done by balancing the good functions with the evil functions? Or is everthing useful within the meaning of the law, if it is used (or is designed and adapted to be used) to accomplish a good result, though in fact it is oftener used (or is as well or even better adapted to be used) to accomplish a bad one? Or is utility negatived by the mere fact that the thing in question is sometimes injurious to morals, or to health, or to good order? The third hypothesis cannot stand, bePage 276cause If it could, it would be fatal to patents for steam engines, dynamos, electric railroads, and indeed many of the noblest inventions of the nineteenth century. The first hypothesis cannot stand, because if it could, it would make the validity of the patents to depend on a question of fact to which it .would often be impossible to give a reliable answer. The second hypothesis is the only one which is consistent with the reason of the case, and with the practical construction which the courts have given to the statutory requirement of utility.”
. We deem the additions to the second hypothesis necessary to a complete statement of the acceptable test, for, to continue with Colt’s revolver as an example, if at the time of a suit for infringement the defendant should prove that the only uses to which “that instrument of death” had been put were vicious, the patent should not be held void for want of utility, if the court for itself should see, or be convinced by experts, that the instrument was susceptible of good uses, though in fact never put to such before the suit was begun. ' And, if utility is found, the cases seem to be uniform that courts will not set up a measure of utility which must be filled.
If the device here in question should be found insusceptible of other use than to guard gambling machines from being operated by means of bogus coins, we would be led to an outlook from which two interesting queries appear in view: (i) The statutes of Illinois, it is said, prohibit the use of coin-operated gambling machines, but not the manufacture or sale thereof. We are referred to statutes of other states, which, it is claimed, legitimate the use of such machines. Should a circuit court of the United States, sitting in Illinois, hold invalid a patent on such a machine and thereby destroy the monopoly of its manufacture and sale, because its use is forbidden in Illinois, though its manufacture and sale in Illinois and its use in certain other states are lawful? And (2) if the federal courts may properly hold patents on gambling machines, void for lack of utility, because immoral, though countenanced by the legislation of particular states, is a device attached to such a machine likewise inimical to good morals, which prevents a gambler from being also a cheat?
But, returning to the main road, we have no difficulty, under the principles hereinabove asserted, in finding some degree of utility in this invention. In the specifications and claims the device is called a bogus-coin detector for coin-operated vending machines. The inventor’s attention to the need of such a mechanism was not directed by the Mills Novelty Company or other maker of chance machines. A manufacturer of coin-operated banjo-playing instruments expressed a want for a bogus-coin detector. The invention in suit resulted. The parties failed to come to terms, not because the detector would not supply the need for which it was designed, but because the inventor asked more than the banjo manufacturer was willing to pay. After-wards the application was assigned to the Mills Novelty Company, and by it the device was applied to gambling machines. " There is no element of chance, however, in the operations of the detector. Its mechanism has no connection with that of the machine to which it is attached. The outlets of its coin chutes are placed in registration with the inlets of the chutes of the coin-operated machine. “The object of the invention,” says the specification, “is to provide, as an attach
The second defense amounts to this: The holder of a legal patent, who refuses to use or permit others to use his device for good purposes, and who prostitutes his invention in practice, will be given no relief in equity, though on the facts shown he could successfully maintain an action at law against the infringer. As counsel states it: “The court wholly disapproves of the complainant suitor, and declines to aid him, though the patent still retains its life. With that, the court’s decree does not attempt to meddle. * * * There is ample chance ahead to efface the stain if the invention is really capable of worthy use and the patent owner seriously lends himself to accomplish the reform.”
It seems clear that one" who practices his invention in a noxious way only has no better standing in equity than one who declines to use the device for good purposes or to permit others to use it. And in Hoe v. Knap (C. C. ) 27 Fed. 204, 212, there is a statement that “under a patent which gives a patentee a monopoly, he is bound to use the patent himself, or allow others to use it on reasonable terms.” But this doctrine has been vigorously denied, and rightly, we think, in subsequent cases. Roller Mill Co. v. Coombs (C. C.) 39 Fed. 803; Campbell Printing Press & Mfg. Co. v. Manhattan R. Co. (C. C.) 49 Fed. 935; Heaton-Peninsular Button-Fastener Co. v. Eureka Specialty Co., 25 C. C. A. 267, 77 Fed. 294, 47 U. S. App. 146. An extract from the last cited case, quoted in Bement v. National Harrow Co., 186 U. S. 70, 90, 22 Sup. Ct. 747, 46 L. Ed. 1058, will sufficiently indicate the general attitude:
Page 278. “If he see fit, lie may reserve to himself the exclusive use of his invention or discovery. If he will neither use his device nor permit others to use it, he has but suppressed his own. That the grant is made upon the reasonable expectation that he will either put his invention to practical use, or permit others to avail themselves of it upon reasonable terms, is doubtless true. This expectation is based alone upon the supposition that the patentee’s interest will induce him to use, or let others use, his invention. The public has retained no other security to enforce such expectations. A suppression can endure but for the life of the patent, and the disclosure he has made will enable all to enjoy the fruit of his genius. His title is exclusive, and so clearly within the constitutional provisions in respect of private property that he is neither bound to use his discovery himself nor permit others to use it. The dictum found in Hoe v. Knap (C. C.) 27 Fed. 204, is not supported by reason or authority.”
So nonuse is not a defense in equity. Is misuse? Equity is not concerned with the general morals of a complainant; the taint that is regarded must affect the particular rights asserted in his suit. Saddle Co. v. Troxel (C. C.) 98 Fed. 620; Folding Box Co. v. Robertson (C. C.) 99 Fed. 985, and cases therein collated. A complainant asserts the validity of his patent (a question of law on the facts), and infringement by defendant (a question of law on the facts), and asks an injunction on account of continued and threatened trespasses (an equitable remedy to make up for the inadequacy of the legal). Though the defendant may not be able to deny the validity of the patent or the fact of infringement, he may defeat the application for an injunction if he can show that the complainant, in his dealings with or conduct towards the defendant in relation to the subject-matter of the litigation, has acted unfairly or oppressively, or .has misled the defendant with respect to the validity of the patent or the fact of infringement, or if the complainant, to make his case, is compelled to bring forward and count upon his own wrong. But if the defendant ■can do no more than show that the complainant has committed some legal or moral offense, which affects the defendant only as it does the public at large, the court must grant the equitable remedy and leáve the punishment of the offender to other forums. In the present case, there have been no dealings between the parties. Nothing has been done to mislead appellees. And appellant, to make his case, simply brings forward his patent and proves the continued and threatened infringement. Against this, appellees establish that appellant has been misusing the patented device. But how does this concern appellees more' or differently than it does others ? Equity will aid the owner of a lawful patent if he puts the device to good uses, but will deny relief if he puts it to bad uses? The “reform,” for the lack of. which appellees contend that appellant must be kept out of a court of equity for the present and until the reform is- accomplished, is the reform of the man.
The conclusion follows from the foregoing premises that appellant is entitled to injunctive relief. But another consideration leads more strongly to the same result. The inventor’s right to make, vend, and use his device does not come from the patent law; it is his natural right. The government’s grant to the patentee and his assigns is the right to exclude others from practicing the invention. As Mr. •Chief Justice Taney said in Bloomer v. McQuewan, 14 How. 539, 548,
It is sometimes said that the granting of an injunction is a matter of discretion. But courts of equity may not exercise a mere arbitrary discretion. They must act within and according to definite and certain principles. The conscience of equity is not the conscience of the particular chancellor. But if the conscience of equity were the conscience of the individual chancellors of this court, who, for example, may think that the public sentiment against the liquor traffic would be vindicated by denying the writ of injunction to an habitual •drunkard whose property by repeated trespasses was being illegally confiscated, the appeal made in this case to deny the writ of injunction, on the ground that its issuance would aid crime and abet practices universally denounced, exhibits a misapprehension of the scope of this litigation. It is obvious that a denial of the writ would leave the defendants and all others perfectly free, so far as the power of this court is concerned, to follow the practices that are repugnant to the individual chancellors, while the maintenance of the complainant’s right to exclude the defendants and all others would, to the extent that the patented device might otherwise be used by them to promote gambling, be a vindication of the public sentiment against gambling. It is equally obvious that, however the court may act upon complainant’s asserted right to exclude, neither the grant nor the denial of the writ of injunction would operate upon complainant’s practices or habits (which he did not acquire from the patent laws), and that the gambler, like the drunkard, is amenable to the municipal authorities alone for violations of the municipal law.
