after stating the case as above, delivered the opinion of the court.
The Circuit Court instructed the jury to return a verdict for the defendant in error, holding the contract void on three grounds: First, that it was contrary to public policy, in that it tends to create a monopoly; second, that it is prohibited by the provisions of section 1673 of the Civil Code of the State of California; and, third, that it was contrary to public policy, for the reason that it provided for oppressive litigation. That such a contract is not void as against public policy, in that it tends to create a monopoly, has been decided by the Supreme Court in the case of Bement v. National Harrow Co., 186 U. S. 70, 22 Sup. Ct. 747, 46 L. Ed. 1058. In that case a contract had been entered into between the National Harrow Company and various other corporations and firms engaged in manufacturing float spring tooth harrows, their frames and attachments, under various patents, 85 in number, which were assigned to the National Harrow Company. That corporation then entered into contracts with the other parties to the agreement, and gave to each a license very similar to the license in question in the present suit. The license provided that the licensee should pay a fixed royalty, should make verified reports of its business, and that it should not sell its products manufactured under the license at a lower price or on -more favorable terms of payment than was set forth in a schedule which was made a part of the license, except that the licensor reserved the right to reduce the selling price and to reduce the royalty. The licensee agreed that it would not, during the continuance of the license, directly or indirectly engage in the manufacture or sale of any other float spring tooth harrows, etc., than those which it was licensed to manufacture and make under the terms of the license, excent such as it might manufacture and furnish another licensee of the National Harrow Company, and then only such constructions thereof as such other licensee should be licensed by the National Harrow Company to manufacture and sell, except such other style and construction as it might be licensed to manufacture and sell by the National Harrow Company. Provision was made for the payment of fixed liquidated damages for breach of certain of the terms of the license, and the licensee agreed not to, directly or indirectly, in any way contest the validity of any patent under which it was licensed to manufacture, or which it might manufacture for another licensee; and it agreed also not to alter or change the construction of the float spring tooth harrow, the frames, etc., which it was authorized to manufacture under the license and under the patents. The licensor covenanted not to grant licenses to any other person or any right to manufacture articles of the peculiar style and construction, or embodying the peculiar features thereof, used by the licensee. It was agreed that the license should continue during *369the life of the patent or patents applicable thereto, and during the term of any reissue thereof. There were other provisions of the contract not necessary here to be considered. The licensee having violated the contract, suit was brought to recover damages and to- restrain further breaches. The licensee, in defense thereof, answered that the license grew out of a combination of the National Harrow Company and other manufacturers and dealers, which amounted to a combination to regulate the manufacture and provide for the sale of float spring tooth harrows at fixed prices throughout the United States, and that said combination was void, as in restraint of trade, and a monopoly prohibited by the Sherman act. In the opinion of the court Mr. Justice Peckham said of the patent laws of the United States:
“The very object of these laws is monopoly, and the rule is, with few exceptions, that any conditions which are not in their very nature illegal with regard to this kind of property, imposed by the patentee and agreed to by the licensee for the right to manufacture or use or sell the article, will be upheld by the courts. The fact that the conditions in the contracts keep up the monopoly or fix prices does not render them illegal.”
Concerning the application of the Sherman act to the contract in question, the court said:
“But that statute clearly does not refer to that kind of a restraint of interstate commerce which may arise from reasonable and legal conditions imposed upon the assignee or licensee of a patent by the owner thereof, restricting the terms upon which the article may be used and the price to be demanded therefor. * * * The owner of a patented article can, of course, charge such price as he may choose, and the owner of a patent may assign it or sell the right to manufacture and sell the article patented upon the condition that the assignee shall charge a certain amount for such article. It is also objected that the agreement of the defendant not to manufacture or sell any other float spring tooth harrow, etc., than those which it had made under its patents before assigning them to the plaintiff, or which it was licensed to manufacture and make under the terms of the license, except such other style and construction as it may be licensed to manufacture and sell by the plaintiff, is void under the act of Congress. The plain purpose of the provision was to prevent the defendant from infringing upon the rights of others under other patents, and it had no purpose to stifle competition in the harrow business more than the patent provided for, nor was its purpose to prevent the licensee from attempting to make any improvement in harrows. It was a reasonable prohibition for the defendant, who would thus be excluded from making such harrows as were made by others who were engaged in manufacturing and selling other machines under other patents. It would be unreasonable to so construe the provision as to prevent defendant from using any letters patent legally obtained by it and not infringing patents owned by others. This was neither its purpose nor its meaning.”
We think the principles announced in that case must control our decision of the question which is here presented, and under its authority we hold that the contract in question in the present case is not void as against public policy, as tending to create a monopoly, or as obnoxious to the provisions of the Sherman anti-trust act.
The principles announced in the case just cited are applicable also to the question whether the contract was prohibited by section 1673 *370of the Code of Civil Procedure of California. That section reads as follows:
“Every contract by which one is restrained from exercising a lawful profession, trade, or business of any kind otherwise than as provided by the next two sections, is to that extent void.”
The next two sections referred to have no relevancy to the questions involved in the present case, and need not be quoted. That the provisions of a state law cannot affect rights acquired under a patent of the United States, is too plain to require discussion. In Columbia Wire Co. v. Freeman Wire Co. (C. C.) 71 Fed. 302, 306, the court said:
“The entire theory and purpose of our patent laws is to create a limited monopoly. In consideration that a patentee will give his invention to the public, with full drawings and specifications, so as to enable the public to freely use it at the expiration of 17 years, a grant is made to him of an exclusive right to the monopoly of the patented device during that time. The rights so acquired by the patentee under a grant from the United States are entirely inconsistent with the patentee’s being made subject to the provision's of the anti-trust laws of the several states.” •
But, whatever may be the effect of the section of the California statute quoted as regards the contract in question, we hold that it can have no relevancy to any portion thereof except that covenant of the licensee embodied in the fourth provision of the license contract that it shall “neither sublet any of said machines, nor allow any parties, except its own employés, to have possession or control of, or to use said machines; shall not use any other raisin-seeding machines during the life of this contract than those furnished by the first party, or with their consent; and shall not buy, sell, nor deal in raisins seeded or treated by any other machines or processes than those of the first party.” If that provision of the contract is, indeed, rendered void by the local statute, none of the questions presented in this case is thereby affected, as that provision is not involved in the litigation. The plaintiff in error sued on two covenants only of the license contract — the covenant to pay a royalty, and the covenant not to sublet the machines. These are valid and subsisting covenants, and are not affected by section 1673, which provides that the contract which contravenes that section is only “to that extent void.” In Oregon Railway & Navigation Co. v. Winsor, 20 Wall. 64, 70, 22 L. Ed. 315, the court affirmed the doctrine “that agreements in restraint of trade, whether under seal or not, are divisible; and accordingly it has been held that, when such an agreement contains a stipulation which is capable of being construed divisibly, and one part thereof is void as being in restraint of trade, whilst the other is not, the court will give effect to the latter, and will not hold the agreement to be void altogether.”
It remains to be considered whether the original contract of' June 26, 1900, is void, or so tainted with inequity that a court will not enforce its provisions, for the reason that it provides for oppressive litigation against third persons. The contract itself contains in its terms no provision for oppressive litigation. It contains a covenant on the part of the plaintiff in error to “institute and defend suits based *371upon or concerning the inventions and letters patent above specified, and such others as may hereafter be acquired by it under and by virtue of this agreement.” The license contract contained a provision requiring the plaintiff in error to “vigorously prosecute infringers of said letters patent, SO' as to prevent as far as possible all unlawful interference with the business and rights of said party of the second part under and by virtue of the contract.” These are proper provisions, and they are not open to criticism. The ruling of the trial court was based upon certain oral testimony adduced upon the trial. There was no issue raised by the pleadings to which such testimony was applicable. The defendant in error had, it is true, alleged "in its answer “that the object of the said combination was not only the purpose aforesaid, but also for the purpose of forcing out of the seeded raisin business the individuals, companies, and corporations who did not unite with the said plaintiff and join with it in its scheme and plan.” That purpose, as pleaded in the answer, was not necessarily an illegal one. The answer did not aver that the said alleged purpose was expressed in the terms of the contract of June 26, 1900, or that the contract itself provided in any way for unjust or oppressive litigation. So far from making that allegation, the defendant in error set up in its answer as one of its grounds of defense, and as a reason for rescinding the contract, that the plaintiff in error, having promised’ vigorous prosecution of infringers of said letters patent, failed to perform the promised service. The averment of the answer that one of the unexpressed purposes of the combination was to force out of the seeded raisin business those who did not take licenses thereunder is presumably true, when it is considered that the whole of the new art of seeding raisins by machinery was covered by the patents which were pooled in the combination. The natural result of such a combination would be tO' force out of business all who did not obtain licenses from the plaintiff in error, for they would necessarily be infringers. The oral evidence which prompted the action of the trial court in withdrawing the case from the jury was the testimony of the president of the defendant in error, who had been an active agent in effecting the combination, that it was the “design of the organization or the understanding,” that litigation was to be instituted' against those who refused to take licenses, “both for the purpose of wearing them out and because they were infringers.” The same witness testified later, however, that it was the purpose to close up such third parties by bringing suit against them “for infringing of patents.” There was the testimony, also, of another, who said that Williamson, the secretary of the plaintiff in error, stated to the witness that he was going to close up and wear out of business all who did not take out a license. Admitting that a contract legal in its terms and in its consideration may be rendered illegal, as against public policy, by reason of the intention of the parties thereto at the time of entering into it to so use it as thereby to commit civil injury to third persons, it may nevertheless be doubted whether the mere existence in the minds of some of the contracting parties of such a purpose — a purpose different from the main purpose, and never in fact carried into execution — is, after the contract has been acted upon and acquiesced in inter partes *372for eight months, ground sufficient to justify the denial of any remedy thereon. But, however that may be, we are clearly of the opinion that if, in view of the pleadings and the law applicable thereto, the question of the existence of such' an illegal purpose was properly before the court as affecting the legality of the contract, it was, under the evidence, a question of fact which should have been submitted to the jury for its decision. There was evidence before the court and jury tending to contradict the evidence that such a purpose existed. There was the testimony of three of the officers of the plaintiff in error taken upon depositions in New York upon the general issues raised by the answer, in which they deposed in substance that the contract itself embodied all of the representations made to induce its execution, and that its objects were fully expressed in its terms. There was the testimony, also, of others who were asked to take out licenses under the contract, who stated that the officers of the plaintiff in error made no representation to them that suits would be brought against others, except on account of infringement of the patents.
The judgment of the lower court is reversed, and the cause remanded for a new trial.
