The Supreme Court, in an opinion written by Justice
Clarke affirmed the judgment. Justice
Holmes, joined by Justices McKenna and Van Devanter, dissented.
Majority opinion The patent statute Justice Clarke began his analysis by observing that the patent statute does not provide for and thus authorize notices of the type involved here. Therefore, "whatever validity it [the notice] has must be derived from the general, and not from the patent, law." The statute gives the patentee the exclusive right to make, sell, and use the patented article. In interpreting the statute, three important rules have been declared by the Court: • "The scope of every patent is limited to the invention described in the claims." The patentee "can claim nothing beyond them." • The statute gives the patentee nothing but the power "to restrain others from manufacturing, using, or selling that which he has invented." • "Since
Pennock v. Dialogue, 2 Pet. 1, was decided in 1829, this Court has consistently held that the primary purpose of our patent laws is not the creation of private fortunes for the owners of patents, but is 'to promote the progress of science and the useful arts.' " Accordingly: These rules of law make it very clear that the scope of the grant which may be made to an inventor in a patent, pursuant to the statute, must be limited to the invention described in the claims of his patent, and, to determine what grant may lawfully be so made, we must hold fast to the language of the act of Congress providing for it. This patent is only on the film projector mechanism described and claimed in the patent, the Court said. By the same token: It is not concerned with, and has nothing to do with, the materials with which or on which the machine operates. The grant is of the exclusive right to use the mechanism to produce the result with any appropriate material, and the materials with which the machine is operated are no part of the patented machine or of the combination which produces the patented result. The difference is clear and vital between the exclusive right to use the machine, which the law gives to the inventor, and the right to use it exclusively with prescribed materials to which such a license notice as we have here seeks to restrict it.
The rise of the inherency doctrine Until recently, the Court said, this plain meaning of the statute was generally understood as the law. But with the growth of corporations the idea had arisen "of gathering great profits in small payments, which are not realized or resented, from many, rather than smaller or even equal profits in larger payments" and so patentees have come to seek to assert "the right to restrict the use of [patented machinery] to materials or supplies not described in the patent, and not, by its terms, made a part of the thing patented." A majority of the Supreme Court had accepted that principle several years earlier in
Henry v. A.B. Dick Co. Justice Clarke denied the legitimacy of this doctrine, because it extended the power of the patent monopoly from the claimed and patented invention—the mechanism described in the patent—to the unpatented supplies used with the mechanism, which were no part of the statutory monopoly: [F]or the reasons stated in this opinion, we are convinced that the exclusive right granted in every patent must be limited to the invention described in the claims of the patent, and that it is not competent for the owner of a patent, by notice attached to its machine, to in effect extend the scope of its patent monopoly by restricting the use of it to materials necessary in its operation, but which are no part of the patented invention, or to send its machines forth into the channels of trade of the country subject to conditions as to use or royalty to be paid, to be imposed thereafter at the discretion of such patent owner. The patent law furnishes no warrant for such a practice, and the cost, inconvenience, and annoyance to the public which the opposite conclusion would occasion forbid it. The Court therefore concluded, first, that
Henry v. A.B. Dick must be overruled. Second, the notice on the plate affixed to the machine contains an invalid restriction that the machine must be used only with film embodying the invention of the Edison patent that expired in 1914. "[S]uch a film is obviously not any part of the invention of the patent in suit." Therefore, the notice "is an attempt, without statutory warrant, to continue the patent monopoly in this particular character of film after it has expired," and to enforce it "would be to create a monopoly in the manufacture and use of moving picture films wholly outside of the patent in suit and of the patent law as we have interpreted it." This notice restriction is contrary to public policy: A restriction which would give to the plaintiff such a potential power for evil over an industry which must be recognized as an important element in the amusement life of the nation, under the conclusions we have stated in this opinion, is plainly void because wholly without the scope and purpose of our patent laws, and because, if sustained, it would be gravely injurious to that public interest, which we have seen is more a favorite of the law than is the promotion of private fortunes.
Holmes dissent Justice Holmes had been part of the majority of the Court that endorsed the inherency doctrine in
Henry v. A.B. Dick, and he strongly dissented from its rejection and overruling in the
Motion Picture Patents case. Justices McKenna and Van Devanter, also in the majority in
A.B. Dick, joined the Holmes dissent here. Holmes reasoned that a patentee may keep his invention out of use for the term of the patent, for whatever reason he may choose. "So much being undisputed, I cannot understand why he may not keep it out of use unless the licensee, or, for the matter of that, the buyer, will use some unpatented thing in connection with it." He added, "
Non debet, cui plus licet, quod minus est non licere." Holmes did allow, however, "No doubt this principle might be limited or excluded in cases where the condition tends to bring about a state of things that there is a predominant public interest to prevent." But he was quick to add that in his view "there is no predominant public interest to prevent a patented teapot or film feeder from being kept from the public, because, as I have said, the patentee may keep them tied up at will while his patent lasts." He also saw no problem in the alleged extension of the patent monopoly from the claimed mechanism to the films made the condition of use of the mechanism. That effect occurs "only to the extent of the desire for the teapot or film feeder, and if the owner prefers to keep the pot or the feeder unless you will buy his tea or films, I cannot see, in allowing him the right to do so, anything more than an ordinary incident of ownership." ==Subsequent developments==
