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.
Sufficiency of disclosure or enablement is a patent law requirement that a patent application disclose a claimed invention in sufficient detail so that the person skilled in the art could carry out that claimed invention. The requirement is fundamental to patent law: a monopoly is granted for a given period of time in exchange for a disclosure to the public how to make or practice the invention.
Rowell v. Lindsay, 113 U.S. 97 (1885), was a bill brought by the appellants, John S. Rowell and Ira Rowell, the plaintiffs in the circuit court. The bill was in equity against Edmund J. Lindsay and William Lindsay, the appellees, to restrain the infringement of reissued letters patent No. 2,909, dated March 31, 1868, granted to the plaintiffs for 'a new and improved cultivator.
The history of United States patent law started even before the U.S. Constitution was adopted, with some state-specific patent laws. The history spans over more than three centuries.
Hotchkiss v. Greenwood, 52 U.S. 248 (1851), was a United States Supreme Court decision credited with introducing into United States patent law the concept of non-obviousness as a patentability requirement, as well as stating the applicable legal standard for determining its presence or absence in a claimed invention.
General Talking Pictures Corp. v. Western Electric Co., 304 U.S. 175 (1938), was a case that the Supreme Court of the United States decided in 1938. The decision upheld so-called field-of-use limitations in patent licenses: it held that the limitations were enforceable in a patent infringement suit in federal court against the licensee and those acting in concert with it—for example, a customer that knowingly buys a patented product from the licensee that is outside the scope of the license.
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.
Funk Brothers Seed Co. v. Kalo Inoculant Co., 333 U.S. 127 (1948), is a United States Supreme Court decision in which the Court held that a facially trivial implementation of a natural principle or phenomenon of nature is not eligible for a patent.
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".
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.
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.
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.
Leitch Manufacturing Co. v. Barber Co., 302 U.S. 458 (1938), is a 1938 decision of the United States Supreme Court extending the tie-in patent misuse doctrine to cases in which the patentee does not use an explicit tie-in license but instead relies on grants of implied licenses to only those who buy a necessary supply from it.
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.
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.
Essayons was a dredge boat of the United States Army Corps of Engineers built to clear navigable channels at the mouth of the Mississippi River. The ship was launched in 1868. Her design was unusual and ultimately not successful. She was mechanically unreliable, and spent much of her career undergoing repairs and upgrades to improve her performance. She was sold by the Corps of Engineers in 1882. It is not clear that she had any further employment.
