In United States patent law, an article of manufacture (also termed a manufacture) is one of the four principal categories of things that may be patented. The other three are a process (also termed a method), a machine, and a composition of matter. In United States patent law, that same terminology has been in use since the first patent act in 1790 (with the exception that processes were formerly termed "arts"). [1]
In In re Nuitjen, [2] the United States Court of Appeals for the Federal Circuit said:
The Supreme Court has defined "manufacture" (in its verb form) as "the production of articles for use from raw or prepared materials by giving to these materials new forms, qualities, properties, or combinations, whether by hand-labor or by machinery." Diamond v. Chakrabarty, 447 U.S. 303, 308 (1980) (quoting American Fruit Growers, Inc. v. Brogdex Co., 283 U.S. 1, 11 (1931). The term is used in the statute in its noun form, Bayer AG v. Housey Pharms., Inc., 340 F.3d 1367, 1373 (Fed. Cir. 2003), and therefore refers to "articles" resulting from the process of manufacture. The same dictionary the Supreme Court relied on for its definition of "manufacture" in turn defines "article" as "a particular substance or commodity: as, an article of merchandise; an article of clothing; salt is a necessary article." 1 Century Dictionary 326 (William Dwight Whitney ed., 1895). These definitions address "articles" of "manufacture" as being tangible articles or commodities. [3]
Examples of articles of manufacture are ceramics, cast metal articles, [4] hammers, crowbars, chairs, shovels, gloves, shoes, envelopes and mouse-pads. Articles of manufacture may have parts, but any interaction among the parts is usually static.
A natural article, even if subjected to a process, as when the rind of an orange is impregnated with borax to prevent decay, is not an article of manufacture. Thus, in American Fruit Growers, Inc. v. Brogdex Co., [5] the Supreme Court held:
Addition of borax to the rind of natural fruit does not produce from the raw material an article for use which possesses a new or distinctive form, quality, or property. The added substance only protects the natural article against deterioration by inhibiting development of extraneous spores upon the rind. There is no change in the name, appearance, or general character of the fruit. It remains a fresh orange, fit only for the same beneficial uses as theretofore. [6]
A signal is not an article of manufacture because intangible, incorporeal, transitory entities are not articles of manufacture. [7]
In United States patent law, utility is a patentability requirement. As provided by 35 U.S.C. § 101, an invention is "useful" if it provides some identifiable benefit and is capable of use and "useless" otherwise. The majority of inventions are usually not challenged as lacking utility, but the doctrine prevents the patenting of fantastic or hypothetical devices such as perpetual motion machines.
Neither software nor computer programs are explicitly mentioned in statutory United States patent law. Patent law has changed to address new technologies, and decisions of the United States Supreme Court and United States Court of Appeals for the Federal Circuit (CAFC) beginning in the latter part of the 20th century have sought to clarify the boundary between patent-eligible and patent-ineligible subject matter for a number of new technologies including computers and software. The first computer software case in the Supreme Court was Gottschalk v. Benson in 1972. Since then, the Supreme Court has decided about a half dozen cases touching on the patent eligibility of software-related inventions.
Business method patents are a class of patents which disclose and claim new methods of doing business. This includes new types of e-commerce, insurance, banking and tax compliance etc. Business method patents are a relatively new species of patent and there have been several reviews investigating the appropriateness of patenting business methods. Nonetheless, they have become important assets for both independent inventors and major corporations.
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 of 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.
Patentable, statutory or patent-eligible subject matter is subject matter which is susceptible of patent protection. The laws or patent practices of many countries provide that certain subject-matter is excluded from patentability, even if the invention is novel and non-obvious. Together with criteria such as novelty, inventive step or nonobviousness, utility, and industrial applicability, which differ from country to country, the question of whether a particular subject matter is patentable is one of the substantive requirements for patentability.
Gottschalk v. Benson, 409 U.S. 63 (1972), was a United States Supreme Court case in which the Court ruled that a process claim directed to a numerical algorithm, as such, was not patentable because "the patent would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself." That would be tantamount to allowing a patent on an abstract idea, contrary to precedent dating back to the middle of the 19th century. The ruling stated "Direct attempts to patent programs have been rejected [and] indirect attempts to obtain patents and avoid the rejection ... have confused the issue further and should not be permitted." The case was argued on October 16, 1972, and was decided November 20, 1972.
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.
In re Bilski, 545 F.3d 943, 88 U.S.P.Q.2d 1385, was an en banc decision of the United States Court of Appeals for the Federal Circuit (CAFC) on the patenting of method claims, particularly business methods. The Federal Circuit court affirmed the rejection of the patent claims involving a method of hedging risks in commodities trading. The court also reiterated the machine-or-transformation test as the applicable test for patent-eligible subject matter, and stated that the test in State Street Bank v. Signature Financial Group should no longer be relied upon.
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.
In United States patent law, the machine-or-transformation test is a test of patent eligibility under which a claim to a process qualifies for consideration if it (1) is implemented by a particular machine in a non-conventional and non-trivial manner or (2) transforms an article from one state to another.
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.
In United States patent law, a machine is one of the four principal categories of things that may be patented. The other three are a process, an article of manufacture, and a composition of matter. In United States patent law, that same terminology has been in use since the first patent act in 1790.
In United States patent law, a composition of matter is one of the four principal categories of things that may be patented. The other three are a process, a machine, and an article of manufacture. In United States patent law, that same terminology has been in use since the first patent act in 1790.
In United States patent law, a method, also called "process", is one of the four principal categories of things that may be patented through "utility patents". The other three are a machine, an article of manufacture, and a composition of matter.
Bilski v. Kappos, 561 U.S. 593 (2010), was a case decided by the Supreme Court of the United States holding that the machine-or-transformation test is not the sole test for determining the patent eligibility of a process, but rather "a useful and important clue, an investigative tool, for determining whether some claimed inventions are processes under § 101." In so doing, the Supreme Court affirmed the rejection of an application for a patent on a method of hedging losses in one segment of the energy industry by making investments in other segments of that industry, on the basis that the abstract investment strategy set forth in the application was not patentable subject matter.
AT&T Corp. v. Excel Communications, Inc., 172 F.3d 1352 was a case in which the United States Court of Appeals for the Federal Circuit reversed the decision of the United States District Court for the District of Delaware, which had granted summary judgment to Excel Communications, Inc. and decided that AT&T Corp. had failed to claim statutory subject matter with U.S. Patent No. 5,333,184 under 35 U.S.C. § 101. The United States Court of Appeals for the Federal Circuit remanded the case for further proceedings.
Bowman v. Monsanto Co., 569 U.S. 278 (2013), was a United States Supreme Court patent decision in which the Court unanimously affirmed the decision of the Federal Circuit that the patent exhaustion doctrine does not permit a farmer to plant and grow saved, patented seeds without the patent owner's permission. The case arose after Vernon Hugh Bowman, an Indiana farmer, bought transgenic soybean crop seeds from a local grain elevator for his second crop of the season. Monsanto originally sold the seed from which these soybeans were grown to farmers under a limited use license that prohibited the farmer-buyer from using the seeds for more than a single season or from saving any seed produced from the crop for replanting. The farmers sold their soybean crops to the local grain elevator, from which Bowman then bought them. After Bowman replanted the crop seeds for his second harvest, Monsanto filed a lawsuit claiming that he infringed on their patents by replanting soybeans without a license. In response, Bowman argued that Monsanto's claims were barred under the doctrine of patent exhaustion, because all future generations of soybeans were embodied in the first generation that was originally sold.
J. E. M. Ag Supply, Inc. v. Pioneer Hi-Bred International, Inc., 534 U.S. 124 (2001), was a decision of the United States Supreme Court holding for the first time that utility patents may be issued for crops and other flowering plants under 35 U.S.C. § 101. The Supreme Court rejected the argument that the exclusive ways to protect these plants are under the Plant Variety Protection Act (PVPA), 7 U.S.C. § 2321, and the Plant Patent Act of 1930 (PPA), 35 U.S.C. §§ 161-164.
Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp., 382 U.S. 172 (1965), was a 1965 decision of the United States Supreme Court that held, for the first time, that enforcement of a fraudulently procured patent violated the antitrust laws and provided a basis for a claim of treble damages if it caused a substantial anticompetitive effect.
