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.
The doctrine of assignor estoppel is a doctrine of United States patent law barring a patent's seller (assignor) from attacking the patent's validity in subsequent patent infringement litigation. The doctrine is based on the doctrine of legal estoppel, which prohibits a grantor from challenging the validity of his/her/its grant.
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.
Lear, Inc. v. Adkins, 395 U.S. 653 (1969), is a decision of the U.S. Supreme Court overturning the doctrine of licensee estoppel and holding that public interest considerations require that licensees be free to challenge the validity of possibly spurious patents under which they are licensed. This entailed the overruling of Automatic Radio Mfg. Co. v. Hazeltine Research, Inc. and prior cases that it had reaffirmed.
Licensee estoppel is a doctrine under which a licensee of an intellectual property right, generally a patent or a trademark, is estopped from challenging the validity of the licensed property. The basis for the doctrine is the premise that a licensee should not be able to enjoy the benefit of an agreement and at the same time attack the validity of the intellectual property that forms the basis of the agreement.
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."
Morton Salt Co. v. G.S. Suppiger Co., 314 U.S. 488 (1942), is a patent misuse decision of the United States Supreme Court. It was the first case in which the Court expressly labeled as "misuse" the Motion Picture Patent/Carbice tie-in defense to a charge of patent infringement and created the present blanket remedy in infringement cases of unenforceability of the misused patent. The decision re-emphasized that misuse can be found without finding an antitrust violation.
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.
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.
Henry v. A.B. Dick Co., 224 U.S. 1 (1912), was a 1912 decision of the United States Supreme Court that upheld patent licensing restrictions such as tie-ins on the basis of the so-called inherency doctrine—the theory that it was the inherent right of a patent owner, because he could lawfully refuse to license his patent at all, to exercise the "lesser" right to license it on any terms and conditions he chose. In 1917, the Supreme Court overruled the A.B. Dick case in Motion Picture Patents Co. v. Universal Film Mfg. Co.,
The Button-Fastener Case, Heaton-Peninsular Button-Fastener Co. v. Eureka Specialty Co., also known as the Peninsular Button-Fastener Case, was for a time a highly influential decision of the United States Court of Appeals for the Sixth Circuit. Many courts of appeals, and the United States Supreme Court in the A.B. Dick case adopted its "inherency doctrine"—"the argument that, since the patentee may withhold his patent altogether from public use, he must logically and necessarily be permitted to impose any conditions which he chooses upon any use which he may allow of it." In 1917, however, the Supreme Court expressly overruled the Button-Fastener Case and the A.B. Dick case, in the Motion Picture Patents case.
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. Motion Picture Patents Co. , 225 F. 800, was a civil antitrust prosecution overlapping to some extent with the issues in the decision in the Supreme Court's Motion Picture Patents case. After the trial court found that the defendants violated §§ 1 and 2 of the Sherman Act by establishing control over "trade in films, cameras, projecting machines, and other accessories of the motion picture business," by their patent licensing practices and other conduct, they appealed to the Supreme Court. After the Supreme Court's 1917 decision in Motion Picture Patents Co. v. Universal Film Manufacturing Co., however, the parties dismissed the appeal by stipulation in 1918' that decision had made the defendants' appeal futile.
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.
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. 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.
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.
