In United States patent law, patent misuse is a patent holder's use of a patent to restrain trade beyond enforcing the exclusive rights that a lawfully obtained patent provides. If a court finds that a patent holder committed patent misuse, the court may rule that the patent holder has lost the right to enforce the patent. Patent misuse that restrains economic competition substantially can also violate United States antitrust law.
Mallinckrodt, Inc. v. Medipart, Inc., 976 F.2d 700, is a decision of the United States Court of Appeals for the Federal Circuit, in which the court appeared to overrule or drastically limit many years of U.S. Supreme Court precedent affirming the patent exhaustion doctrine, for example in Bauer & Cie. v. O'Donnell.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008), is a decision of the United States Supreme Court in which the Court reaffirmed the validity of the patent exhaustion doctrine, and in doing so made uncertain the continuing precedential value of a line of decisions in the Federal Circuit that had sought to limit Supreme Court exhaustion doctrine decisions to their facts and to require a so-called "rule of reason" analysis of all post-sale restrictions other than tie-ins and price fixes. In the course of restating the patent exhaustion doctrine, the Court held that the exhaustion doctrine is triggered by, among other things, an authorized sale of a component when the only reasonable and intended use of the component is to practice the patent and the component substantially embodies the patented invention by embodying its essential features. The Court also overturned, in passing, the part of decision below that held that the exhaustion doctrine was limited to product claims and did not apply to method claims.
United States v. Univis Lens Co., 316 U.S. 241 (1942), is a decision of the United States Supreme Court explaining the exhaustion doctrine and applying it to find an antitrust violation because Univis's ownership of patents did not exclude its restrictive practices from the antitrust laws. The Univis case stands for the proposition that when an article sold by a patent holder or one whom it has authorized to sell it embodies the essential features of a patented invention, the effect of the sale is to terminate any right of the patent holder under patent law to control the purchaser's further disposition or use of the article itself and of articles into which it is incorporated as a component or precursor.
United States v. General Electric Co., 272 U.S. 476 (1926), is a decision of the United States Supreme Court holding that a patentee who has granted a single license to a competitor to manufacture the patented product may lawfully fix the price at which the licensee may sell the product.
A post-sale restraint, also termed a post-sale restriction, as those terms are used in United States patent law and antitrust law, is a limitation that operates after a sale of goods to a purchaser has occurred and purports to restrain, restrict, or limit the scope of the buyer's freedom to utilize, resell, or otherwise dispose of or take action regarding the sold goods. Such restraints have also been termed "equitable servitudes on chattels".
Adams v. Burke, 84 U.S. 453 (1873), was a United States Supreme Court case in which the Court first elaborated on the exhaustion doctrine. According to that doctrine, a so-called authorized sale of a patented product liberates the product from the patent monopoly. The product becomes the complete property of the purchaser and "passes without the monopoly." The property owner is then free to use or dispose of it as it may choose, free of any control by the patentee. Adams is a widely cited, leading case. A substantially identical doctrine applies in copyright law and is known as the "first sale doctrine".
Motion Picture Patents Co. v. Universal Film Mfg. Co., 243 U.S. 502 (1917), is United States Supreme Court decision that is notable as an early example of the patent misuse doctrine. It held that, because a patent grant is limited to the invention described in the claims of the patent, the patent law does not empower the patent owner, by notices attached to the patented article, to extend the scope of the patent monopoly by restricting the use of the patented article to materials necessary for their operation but forming no part of the patented invention, or to place downstream restrictions on the articles making them subject to conditions as to use. The decision overruled The Button-Fastener Case, and Henry v. A.B. Dick Co., which had held such restrictive notices effective and enforceable.
Ethyl Gasoline Corp. v. United States, 309 U.S. 436 (1940), was a decision of the United States Supreme Court that limited the doctrine of the Court's 1938 decision in General Talking Pictures Corp. v. Western Electric Co. Beginning with the 1926 decision in United States v. General Electric Co., the Supreme Court made a sharp distinction between (i) post-sale restraints that a patentee imposed on purchasers of a patented product and (ii) restrictions (limitations) that a patentee imposed on a licensee to manufacture a patented product: the former being illegal and unenforceable under the exhaustion doctrine while the latter were generally permissible under a lenient "rule of reason." Thus, under the General Talking Pictures doctrine, a patent holder may permissibly license others to manufacture and then sell patented products in only a specified field (market), such as only a particular type of product made under the patent or only a particular category of customer for the patented product. The Ethyl decision held, however, that a patent licensing and distribution program based on both the sale of a patented product and licenses to manufacture a related product was subject to ordinary testing under the antitrust laws, and accordingly was illegal when its effect was to "regiment" an entire industry.
Princo Corp. v. ITC, 616 F.3d 1318 was a 2010 decision of the United States Court of Appeals for the Federal Circuit, that sought to narrow the defense of patent misuse to claims for patent infringement. Princo held that a party asserting the defense of patent misuse, absent a case of so-called per se misuse, must prove both "leveraging" of the patent being enforced against it and a substantial anticompetitive effect outside the legitimate scope of that patent right. In so ruling, the court emphasized that the misuse alleged must involve the patent in suit, not another patent.
Impression Products, Inc. v. Lexmark International, Inc., 581 U.S. ___ (2017), is a decision of the Supreme Court of the United States on the exhaustion doctrine in patent law in which the Court held that after the sale of a patented item, the patent holder cannot sue for patent infringement relating to further use of that item, even when in violation of a contract with a customer or imported from outside the United States. The case concerned a patent infringement lawsuit brought by Lexmark against Impression Products, Inc., which bought used ink cartridges, refilled them, replaced a microchip on the cartridge to circumvent a digital rights management scheme, and then resold them. Lexmark argued that as they own several patents related to the ink cartridges, Impression Products was violating their patent rights. The U.S. Supreme Court, reversing a 2016 decision of the Federal Circuit, held that the exhaustion doctrine prevented Lexmark's patent infringement lawsuit, although Lexmark could enforce restrictions on use or resale of its contracts with direct purchasers under regular contract law. Besides printer and ink manufacturers, the decision of the case could affect the markets of high tech consumer goods and prescription drugs.
The Mercoid cases—Mercoid Corp. v. Mid-Continent Investment Co., 320 U.S. 661 (1944), and Mercoid Corp. v. Minneapolis-Honeywell Regulator Co., 320 U.S. 680 (1944)—are 1944 patent tie-in misuse and antitrust decisions of the United States Supreme Court. These companion cases are said to have reached the "high-water mark of the patent misuse doctrine." The Court substantially limited the contributory infringement doctrine by holding unlawful tie-ins of "non-staple" unpatented articles that were specially adapted only for use in practicing a patent, and the Court observed: "The result of this decision, together with those which have preceded it, is to limit substantially the doctrine of contributory infringement. What residuum may be left we need not stop to consider." The Court also suggested that an attempt to extend the reach of a patent beyond its claims could or would violate the antitrust laws: "The legality of any attempt to bring unpatented goods within the protection of the patent is measured by the antitrust laws, not by the patent law."
National Lockwasher Co. v. George K. Garrett Co., 137 F.2d 255, is one of the earliest or the earliest federal court decision to hold that it is patent misuse for a patentee to require licensees not to use a competitive technology. Such provisions are known as "tie-outs."
United States v. New Wrinkle, Inc., 342 U.S. 371 (1952), is a 1952 Supreme Court decision in which the Court held that a claim of conspiracy to fix uniform minimum prices and to eliminate competition throughout substantially all of the wrinkle finish industry of the United States by means of patent license agreements was, if proved, a violation of § 1 of the Sherman Act. That one of the defendants, a patent-holding company, abstained from manufacturing activities, did not ship goods in commerce, and engaged solely in patent licensing did not insulate its activity from § 1. Making these license contracts for the purpose of regulating distribution and fixing prices of commodities in interstate commerce is subject to the Sherman Act, even though the isolated act of contracting for the licenses occurs within a single state. Patents give no protection from the prohibitions of the Sherman Act when the patent licensing agreements are used to restrain interstate commerce and fix prices of goods shipped in commerce.
United States v. Line Material Co., 333 U.S. 287 (1948), is a decision of the United States Supreme Court limiting the doctrine of the 1926 General Electric decision, excusing price fixing in patent license agreements. The Line Material Court held that cross-licenses between two manufacturer competitors, providing for fixing the prices of the licensed products and providing that one of the manufacturers would license other manufacturers under the patents of each manufacturer, subject to similar price fixing, violated Sherman Act § 1. The Court further held that the licensees who, with knowledge of such arrangements, entered into the price-fixing licenses thereby became party to a hub-and-spoke conspiracy in violation of Sherman Act § 1.
Bulk-sale restrictions—also known as bulk-sale restraints, finished-form limitations, and dosage-form limitations—are, as the term is used in United States antitrust case law, clauses in patent licenses that provide that the licensee shall make and sell the licensed product only in "finished pharmaceutical form" or "dosage form", not in bulk. Bulk form is the form in which drug chemicals are manufactured by chemical or other processes. These clauses are found primarily in pharmaceutical product licenses and are used to keep active drug ingredients out of the hands of generic manufacturers and price-cutters.
Rubber Co. v. Goodyear, 76 U.S. 788 (1869), is an early decision of the United States Supreme Court recognizing the right of a patent owner to license another person to practice the invention only in a limited field, and holding that such a licensee committed patent infringement when it made and sold products of the invention outside that field.
