Estoppel is a judicial device in common law legal systems whereby a court may prevent or "estop" a person from making assertions or from going back on his or her word; the person being sanctioned is "estopped". Estoppel may prevent someone from bringing a particular claim. Legal doctrines of estoppel are based in both common law and equity. It is also a concept in international law.
Bauer & Cie. v. O'Donnell, 229 U.S. 1 (1913), was a 1913 United States Supreme Court decision involving whether a purchaser of a patented product bearing a price-fixing notice incurs guilt of patent infringement by reselling the product at a price lower than that which the notice commands. A divided Court (5–4) held that it was not.
The automotive aftermarket is the secondary parts market of the automotive industry, concerned with the manufacturing, remanufacturing, distribution, retailing, and installation of all vehicle parts, chemicals, equipment, and accessories, after the sale of the automobile by the original equipment manufacturer (OEM) to the consumer. The parts, accessories, etc. for sale may or may not be manufactured by the OEM.
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.
Third party standing is a term of the law of civil procedure that describes when one party may file a lawsuit or assert a defense in which the rights of third parties are asserted. In the United States, this is generally prohibited, as a party can only assert his or her own rights and cannot raise the claims of right of a third party who is not before the court. However, there are several exceptions to this doctrine.
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.
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.
Graham v. John Deere Co., 383 U.S. 1 (1966), was a case in which the United States Supreme Court clarified the nonobviousness requirement in United States patent law, set forth 14 years earlier in Patent Act of 1952 and codified as 35 U.S.C. § 103.
An implied license is an unwritten license which permits a party to do something that would normally require the express permission of another party. Implied licenses may arise by operation of law from actions by the licensor which lead the licensee to believe that it has the necessary permission.
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 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.
LB (Plastics) Ltd. v. Swish Products Ltd., is a 1979 decision of the House of Lords as to whether a physical object is an infringing copy of a drawing depicting the object. The House of Lords held that it is, at least when an ordinary person could recognize that physical object was that which the drawing depicted.
The doctrine of non-derogation from grants is a principle of the law of England and Wales. As the House of Lords explained in British Leyland Motor Corp. v. Armstrong Patents Co., it states that a seller of realty or goods is not permitted to take any action that will lessen the value to the buyer of the thing sold.
Canon Kabushiki Kaisha v Green Cartridge Co Ltd is a 1997 decision of the Judicial Committee of the Privy Council (1) re-affirming the principle of UK copyright law that the copying of functional three-dimensional objects is an infringing reproduction of the drawings of the objects, and (2) limiting the doctrine of non-derogation from grants as to chattels to "the case in which the unfairness to the customer and the anticompetitive nature of the monopoly is as plain and obvious as it appeared to the House of Lords in the British Leyland case."
Aro Manufacturing Co. v. Convertible Top Replacement Co., 365 U.S. 336 (1961), is a United States Supreme Court case in which the Court redefined the U.S. patent law doctrine of repair and reconstruction. The decision is sometimes referred to as Aro I because several years later the Supreme Court readdressed the same issues in a second case in 1964 involving the same parties—Aro II.
The doctrine of repair and reconstruction in United States patent law distinguishes between permissible repair of a patented article, which the right of an owner of property to preserve its utility and operability guarantees, and impermissible reconstruction of a patented article, which is patent infringement. The doctrine is explained in Aro Mfg. Co. v. Convertible Top Replacement Co. The Aro case states the rule in these terms:
The decisions of this Court require the conclusion that reconstruction of a patented entity, comprised of unpatented elements, is limited to such a true reconstruction of the entity as to "in fact make a new article," after the entity, viewed as a whole, has become spent. In order to call the monopoly, conferred by the patent grant, into play for a second time, it must, indeed, be a second creation of the patented entity. …Mere replacement of individual unpatented parts, one at a time, whether of the same part repeatedly or different parts successively, is no more than the lawful right of the owner to repair his property.
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.
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.
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.
Right to repair is a legal right for owners of devices and equipment to freely modify and repair products such as automobiles, electronics, and farm equipment. This right is framed in opposition to restrictions such as requirements to use only the manufacturer's maintenance services, restrictions on access to tools and components, and software barriers.
