delivered the opinion of the Court.
The American Patents Development Corporation, as owner of United States Patent No. 1,595,426, and the Dry Ice Corporation, as exclusive licensee, brought this suit in the federal court for eastern New York to enjoin contributory infringement by the Carbice Company, for an accounting of profits, and for damages. The defendant denied both the validity of the patent and the alleged infringement. The District Court, without passing upon validity, dismissed the bill on the ground that infringement had not been shown, 25 F. (2d) 730 . The Circuit Court of Appeals held the patent valid and infringed, 38 F. (2d) 62 . A writ of certiorari was granted, 281 U. S. 711 .
Solid carbon dioxide has a temperature of about 110° below zero. When it “melts,” it passes directly into a dry, gaseous state—the gas having a like temperature and
The patent in suit is not for solid carbon dioxide. That article and its properties as a refrigerant have been long known to the public. The patent is not for a machine for making solid carbon dioxide. Nor is it for a process for making or using that substance. The Patent Office rejected an application for a process patent. The patent is said to be for a manufacture. The specifications outline the method of construction and use; and a typical claim (6) is for a “ transportation package consisting of a protective casing of insulating material having packed therein a quantity of frozen carbon dioxide in an insulating container and a quantity of freezable product in freezing proximity to said frozen carbon dioxide and the gas evaporated therefrom, arranged so that said frozen carbon dioxide is less accessible for exterior heat than said freezable products.”
The sole business of the Dry Ice Corporation is the manufacture of solid carbon dioxide which it sells under
The Carbice Corporation also manufactures solid carbon dioxide. It is charged with contributory infringement because it sells its product to customers of the Dry Ice Corporation with knowledge that the dioxide is to be used by the purchaser in transportation packages like those described in the patent. The Carbice Corporation challenges the validity of the patent and denies infringement. Whether the transportation package ■ described is a patentable invention we need not determine. For even if it is, no relief can be granted.
The invention claimed is for a particular kind of package employing solid carbon dioxide in a new combination.
The relief here sought is indistinguishable from that denied in the Motion Picture case. There, it was held that to permit the patent-owner “-to derive its profit, not
1 In England the insertion of such a requirement in any license agreement is a complete defense to any defendant charged with infringement. See Patents and Designs Act (1907) 7 Edw. VII, c. 29, § 38, as amended by (1919) 9 & 10 Geo. V, c. 80, § 20, Sched. 38; Sarason v. Fréhay [1914] 2 Ch. 474; Huntoon Co. v. Kolynos, Inc., [1930] 1 Ch. Div. 528, 535, 547, 553, 562. The need for such legislative measures to prevent abuse of the patent monopoly has now been recognized by the International Convention for the Protection of Industrial Property. See Actes de la Conference de La Haye de 1925 (Berne, 1926) pp. 433-34, 606; Ladas, International Protection of Industrial Property, pp. 337-40, 817. In this country the patent statutes similarly provide that an unreasonable delay in formally disavowing patent claims held invalid, and the consequent maintenance of a broader monopoly than warranted, is a complete defense to all infringers, even as to remaining valid claims. Rev. Stat. §§ 4917, 4922 ; 35 U. S. C. §§ 65 , 71. See Ensten v. Simon, Ascher & Co., Inc., 282 U. S. 445 .
2 See, also, the examples given by Chief Justice White, dissenting in Henry v. A. B. Dick Co., 224 U. S. 1 , 55. “The very existence of such restrictions suggests that in its absence a competing article of equal or better quality would be offered at the same or at a lower price. . . .” Vaughan, Economics of Our Patent System, pp. 125-127.
3 The patent grant is inherently limited in other respects. A patent covering an essential instrumentality does not enable a patentee or its licensee thereby to abridge its obligations as a public utility; the exclusive right to license use of the invention cannot be so exercised. Missouri ex rel. Baltimore & O. Tel. Co. v. Bell Tel. Co., 23 Fed. 539 , *33 appeal dismissed, 127 U. S. 780 ; State ex rel. Postal Tel. Cable Co. v. Delaware & A. Tel. & Tel. Co., 47 Fed. 633 , affirmed, 50 Fed. 677 . Nor does the grant of a "United States patent exempt the patented product from limitations imposed by state police statutes. Patterson v. Kentucky, 97 U. S. 501 ; Allen v. Riley, 203 U. S. 347 ; John Woods & Sons v. Carl, 203 U. S. 358 ; Ozan Lumber Co. v. Union County National Bank, 207 U. S. 251 . Compare Webber v. Virginia, 103 U. S. 344 , 347. See note 1, supra. Nor can a patent be made the basis of an unconscionable contract. Pope Mfg. Co. v. Gormully, 144 U. S. 224 .
The case at bar is wholly unlike Leeds & Catlin v. Victor Talking Machine Co., 213 U. S. 325 , 333, on which plaintiffs rely. That was an ordinary case of contributory infringement. The Victor Company sold machines embodying a patent for a combination., Leeds & Catlin were held to be infringers because the intended incorporation in the Victor machines of the article which they sold, did not constitute a repair of the machine and hence was not within the license implied on sale. Heyer v. Duplicator Mfg. Co., 263 U. S. 100 . There was no suggestion that the Victor Company, which itself manufactured and sold the patented product, sought “ to derive its profits, not from the invention on which the law gives it a monopoly, but from the unpatented supplies with which it is used." In the case at bar the plaintiffs neither sell nor license others to sell complete transportation packages. They supply merely one of the several materials entering into the combination; and on that
4 In such cases, the attempt to use the patent unreasonably to restrain commerce is not only beyond the scope of the grant, but also a direct violation of the Anti-Trust Acts. Compare § 3 of the Clayton Act, October 15, 1914, c. 323, 38 Stat. 730 , 731, which prohibits any lease, sale, contract, or agreement tending to create a monopoly in any line of commerce, and is applicable to all "goods, wares, merchandise, machinery, supplies or other commodities, whether patented or unpatented. . . .” See United Shoe Mach. Co. v. United States, 258 U. S. 451 , 460; Lord v. Radio Corp. of America, 24 F. (2d) 565 , 566-67, affirmed, 28 F. (2d) 257 , certiorari denied, 278 U. S. 648 , decree entered, 35 F. (2d) 962 , affirmed, 47 F. (2d) 606 . Compare, as to trade secrets, Dr. Miles Medical Co. v. Park & Sons Co., 220 U. S. 373 , 401.

5 Restrictions on the manner of use, essential to prevent unwarranted extension, are inherent in other limited monopolies. Thus, a trademark may not be used as a means of misrepresentation. Worden v. California Fig Syrup Co., 187 U. S. 516 ; Mulhens & Kropff, Inc., v. Ferd. Muelhens, Inc., 43 F. (2d) 937 ; Leather Cloth Co., Ltd., v. American Leather Cloth Co., Ltd., 4 De G. J. & S. 137, affirmed, 11 H. L. C. 523. Nor a tradename as a means of deception. Memphis Keeley Institute v. Keeley Co., 155 Fed. 964 ; Boyd Baking Powder Co. v. Federal Trade Commission, 281 Fed, 744 ; Federal Trade Commssion v. Bradley, 31 F. (2d) 569 .
