A declaratory judgment, also called a declaration, is the legal determination of a court that resolves legal uncertainty for the litigants. It is a form of legally binding preventive by which a party involved in an actual or possible legal matter can ask a court to conclusively rule on and affirm the rights, duties, or obligations of one or more parties in a civil dispute. The declaratory judgment is generally considered a statutory remedy and not an equitable remedy in the United States, and is thus not subject to equitable requirements, though there are analogies that can be found in the remedies granted by courts of equity. A declaratory judgment does not by itself order any action by a party, or imply damages or an injunction, although it may be accompanied by one or more other remedies.
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.
Under United States law, a patent is a right granted to the inventor of a (1) process, machine, article of manufacture, or composition of matter, (2) that is new, useful, and non-obvious. A patent is the right to exclude others, for a limited time from profiting from a patented technology without the consent of the patent holder. Specifically, it is the right to exclude others from: making, using, selling, offering for sale, importing, inducing others to infringe, applying for an FDA approval, and/or offering a product specially adapted for practice of the patent.
European patent law covers a range of legislations including national patent laws, the Strasbourg Convention of 1963, the European Patent Convention of 1973, and a number of European Union directives and regulations. For some states in Eastern Europe, the Eurasian Patent Convention applies.
The exhaustion doctrine, also referred to as the first sale doctrine, is a U.S. common law patent doctrine that limits the extent to which patent holders can control an individual article of a patented product after a so-called authorized sale. Under the doctrine, once an authorized sale of a patented article occurs, the patent holder's exclusive rights to control the use and sale of that article are said to be "exhausted," and the purchaser is free to use or resell that article without further restraint from patent law. However, under the repair and reconstruction doctrine, the patent owner retains the right to exclude purchasers of the articles from making the patented invention anew, unless it is specifically authorized by the patentee to do so.
Japanese patent law is based on the first-to-file principle and is mainly given force by the Patent Act of Japan. Article 2 defines an invention as "the highly advanced creation of technical ideas utilizing the law of nature".
This is a list of legal terms relating to patents and patent law. A patent is not a right to practice or use the invention claimed therein, but a territorial right to exclude others from commercially exploiting the invention, granted to an inventor or their successor in rights in exchange to a public disclosure of the invention.
eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), is a case in which the Supreme Court of the United States unanimously determined that an injunction should not be automatically issued based on a finding of patent infringement, but also that an injunction should not be denied simply on the basis that the plaintiff does not practice the patented invention. Instead, a federal court must still weigh what the Court described as the four-factor test traditionally used to determine if an injunction should be issued.
In the United States, a valid patent provides its proprietor with the right to exclude others from practicing the invention claimed in that patent. A person who practices that invention without the permission of the patent holder infringes that patent.
In the United Kingdom, a patent provides its proprietor with the right to exclude others from utilizing the invention claimed in that patent. Should a person utilize that invention, without the permission of the patent proprietor, they may infringe that patent.
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.
A patent holder in Canada has the exclusive right, privilege and liberty to making, constructing, using and selling the invention for the term of the patent, from the time the patent is granted. Any person who does any of these acts in relation to an invention without permission of the patent owner is liable for patent infringement.
Once an invention is patented in Canada, exclusive rights are granted to the patent holder as defined by s.42 of the Patent Act. Any interference with the patent holder's "full enjoyment of the monopoly granted by the patent" is considered a patent infringement. Making, constructing, using, or selling a patented invention without the patent holder's permission can constitute infringement. Possession of a patented object, use of a patented object in a process, and inducement or procurement of an infringement may also, in some cases, count as infringement.
Patent law in modern mainland China began with the promulgation of the Patent Law of the People's Republic of China, in 1984. This law was modeled after patent systems of other civil law countries, particularly Germany and Japan.
Medtronic, Inc. v. Mirowski Family Ventures, LLC, 571 U.S. 191 (2014), is a case of the Supreme Court of the United States that deals with civil procedure, and specifically with the question of the burden of proof required in pursuing declaratory judgments.
The following outline is provided as an overview of and topical guide to patents:
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.
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."
Dawson Chemical Co. v. Rohm & Haas Co., 448 U.S. 176 (1980), is a 1980 5–4 decision of the United States Supreme Court limiting the patent misuse doctrine and explaining the scope of the 1952 amendment of the patent laws that resurrected the contributory infringement doctrine in the wake of the Mercoid cases. The Mercoid cases and a few predecessor cases had denied relief against patent infringement to patentees who were deriving revenue from the sale of unpatented products used as supplies for patented combinations or as components of patented combinations, even when the unpatented products were specially adapted for use with the patented combinations and even when they lacked any utility other than that use. The patentees used contributory infringement suits or threats of such suits to enforce their business model, which the Mercoid cases outlawed.
