In the United States, antitrust law is a collection of mostly federal laws that regulate the conduct and organization of businesses to promote competition and prevent unjustified monopolies. The three main U.S. antitrust statutes are the Sherman Act of 1890, the Clayton Act of 1914, and the Federal Trade Commission Act of 1914. These acts serve three major functions. First, Section 1 of the Sherman Act prohibits price fixing and the operation of cartels, and prohibits other collusive practices that unreasonably restrain trade. Second, Section 7 of the Clayton Act restricts the mergers and acquisitions of organizations that may substantially lessen competition or tend to create a monopoly. Third, Section 2 of the Sherman Act prohibits monopolization.
Tying is the practice of selling one product or service as a mandatory addition to the purchase of a different product or service. In legal terms, a tying sale makes the sale of one good to the de facto customer conditional on the purchase of a second distinctive good. Tying is often illegal when the products are not naturally related. It is related to but distinct from freebie marketing, a common method of giving away one item to ensure a continual flow of sales of another related item.
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.
International Salt Co. v. United States, 332 U.S. 392 (1947), was a case in which the United States Supreme Court held that the Sherman Act prohibits as per se violations all tying arrangements in which a product for which a seller has a legal monopoly, such as a patent, requires purchasers to buy as well a product for which the seller has no legal monopoly.
Lexmark International, Inc. v. Static Control Components, Inc., is an American legal case involving the computer printer company Lexmark, which had designed an authentication system using a microcontroller so that only authorized toner cartridges could be used. The resulting litigation has resulted in significant decisions affecting United States intellectual property and trademark law.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008), is a case decided by the United States Supreme Court in which the Court reaffirmed the validity of the patent exhaustion doctrine. The decision 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 it is triggered by, among other things, an authorized sale of a component when the only reasonable and intended use of the component is to engage the patent and the component substantially embodies the patented invention by embodying its essential features. The Court also overturned, in passing, that the exhaustion doctrine was limited to product claims and did not apply to method claims.
United States v. Glaxo Group Ltd., 410 U.S. 52 (1973), is a 1973 decision of the United States Supreme Court in which the Court held that (1) when a patent is directly involved in an antitrust violation, the Government may challenge the validity of the patent; and (2) ordinarily, in patent-antitrust cases, "[m]andatory selling on specified terms and compulsory patent licensing at reasonable charges are recognized antitrust remedies."
Standard Sanitary Mfg. Co. v. United States, 226 U.S. 20 (1912), also known as the Bathtub Trust case, was a United States Supreme Court decision in which the Court held unanimously that ownership of patent rights does not immunize the owner from the antitrust laws prohibiting combinations in unreasonable restraint of trade. The Court famously said that the Sherman Act "is its own measure of right and wrong, of what it permits or forbids, and the judgment of the courts cannot be set up against it in a supposed accommodation of its policy with the good intention of parties, and, it may be, of some good results." A 1917 commentary said, "This decision has become the leading case on the subject of the relation of the patent law and Sherman law to each other."
Eastman Kodak Co. v. Image Technical Servs., Inc., 504 U.S. 451 (1992), is a 1992 Supreme Court decision in which the Court held that even though an equipment manufacturer lacked significant market power in the primary market for its equipment—copier-duplicators and other imaging equipment—nonetheless, it could have sufficient market power in the secondary aftermarket for repair parts to be liable under the antitrust laws for its exclusionary conduct in the aftermarket. The reason was that it was possible that, once customers were committed to the particular brand by having purchased a unit, they were "locked in" and no longer had any realistic alternative to turn to for repair parts.
Zenith Radio Corp. v. Hazeltine Research, Inc. is the caption of several United States Supreme Court patent–related decisions, the most significant of which is a 1969 patent–antitrust and patent–misuse decision concerning the levying of patent royalties on unpatented products.
United States v. Singer Mfg. Co., 374 U.S. 174 (1963), was a 1963 decision of the Supreme Court, holding that the defendant Singer violated the antitrust laws by conspiring with two European competitors to exclude Japanese sewing machine competition from the US market. Singer effectuated the conspiracy by agreeing with the two European competitors to broaden US patent rights and concentrate them under Sanger's control in order to more effectively exclude the Japanese firms. A further aspect of the conspiracy was to fraudulently procure a US patent and use it as an exclusionary tool. This was the first Supreme Court decision holding that exclusionary use of a fraudulently procured patent could be an element supporting an antitrust claim.
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.
United States v. United States Gypsum Co. was a patent–antitrust case in which the United States Supreme Court decided, first, in 1948, that a patent licensing program that fixed prices of many licensees and regimented an entire industry violated the antitrust laws, and then, decided in 1950, after a remand, that appropriate relief in such cases did not extend so far as to permit licensees enjoying a compulsory, reasonable–royalty license to challenge the validity of the licensed patents. The Court also ruled, in obiter dicta, that the United States had standing to challenge the validity of patents when a patentee relied on the patents to justify its fixing prices. It held in this case, however, that the defendants violated the antitrust laws irrespective of whether the patents were valid, which made the validity issue irrelevant.
United States v. Westinghouse Electric Corp., 648 F.2d 642, is a patent-antitrust case in which the United States unsuccessfully tried to persuade the court that a patent and technology licensing agreement between major competitors in the highly concentrated heavy electrical equipment market—Westinghouse, Mitsubishi Electric (Melco) and Mitsubishi Heavy Industries (MHI)—which had the effect of territorially dividing world markets, violated § 1 of the Sherman Act. The Government had two principal theories of the case: (1) the arrangement is in unreasonable restraint of trade because its effect is to lessen competition substantially by precluding the Japanese defendant companies from bidding against Westinghouse on equipment procurements in the United States, when they are ready, willing, and able to do so; and (2) the arrangement is an agreement—explicit or tacit—to divide markets, which is illegal per se under § 1. Neither theory prevailed.
Besser Mfg. Co. v. United States, 343 U.S. 444 (1951), is a 1951 patent–antitrust decision of the United States Supreme Court in which the Court upheld a ruling that the dominant U.S. manufacturer of concrete block–making machines violated the antitrust laws when it acquired its two principal competitors, bought important patents, made bad–faith threats of patent infringement suits, and entered into patent licensing agreements in which the parties were given veto powers over any prospective additional licensees. The Supreme Court approved the district court's grant of compulsory, reasonable–royalty licensing of the patents and compulsory sales of patented machines, holding that such relief "is a well–recognized remedy where patent abuses are proved in antitrust actions, and it is required for effective relief."
United States v. Krasnov, 143 F. Supp. 184, was a 1956 district court patent–antitrust decision that the United States Supreme Court affirmed per curiam without opinion. The district court granted the Government's summary judgment motion because it concluded:
That the defendants in combination controlled the market and had the ability to and did drive competitors from the business of manufacturing knitted fabric slip covers is abundantly clear from the record. That the defendants in combination fixed and maintained prices is likewise crystal clear. That the defendants in combination and cross-licensing created a situation in the industry which, particularly by agreement for joint action respecting the patents, effectively hindered newcomers in the field, is also established beyond peradventure of doubt. That the harassing suits against competitors, previously discussed in some detail, were designed as and were actually only harassing suits is clear from an examination of the correspondence between the parties and the Court feels that such conclusion in inescapable from an objective analysis of the documents. All of these actions taken in concert constitute a clear violation of the Sherman Anti-Trust Act and the Government has established to the satisfaction of the Court that the combination and conspiracy above referred to represents an unreasonable restraint of trade and commerce among the several states of the United States in the manufacture and sale of ready-made furniture slip covers, is unlawful, and in violation of Section 1 of the Sherman Anti-Trust Act. Further, the Government, in the opinion of the Court, has effectively demonstrated that the defendants combined and conspired not only to restrain trade unreasonably but also to monopolize trade and commerce among the several states of the United States in the manufacture and sale of ready-made furniture slip covers, in direct violation of Section 2 of the Sherman Anti-Trust Act. The Court also feels that by documentary proof the Government has established that the defendants have used patent rights unlawfully in instituting, effectuating and maintaining the aforesaid combination and conspiracy which likewise constitutes a clear violation of the Sherman Anti-Trust Act.
United States v. Masonite Corp., 316 U.S. 265 (1942), is a United States Supreme Court decision that limited the scope of the 1926 Supreme Court decision in the General Electric case that had exempted patent licensing agreements from antitrust law's prohibition of price fixing. The Court did so by applying the doctrine of the Court's recent Interstate Circuit hub-and-spoke conspiracy decision.
Hartford-Empire Co. v. United States, 323 U.S. 386 (1945), was a patent-antitrust case that the Government brought against a cartel in the glass container industry. The cartel, among other things, divided the fields of manufacture of glass containers, first, into blown glass and pressed glass, which was subdivided into: products made under the suction process, milk bottles, and fruit jars. The trial court found the cartel violative of the antitrust laws and the Supreme Court agreed that the market division and related conduct were illegal. The trial court required royalty-free licensing of present patents and reasonable royalty licensing of future patents. A divided Supreme Court reversed the requirement for royalty-free licensing as "confiscatory," but sustained the requirement for reasonable royalty licensing of the patents.
