United States patent 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 (usually, 20 years) 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. United States patent law is codified in Title 35 of the United States Code, and authorized by the U.S. Constitution, in Article One, section 8, clause 8, which states: The Congress shall have power ... To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries; Although this statement is superficially similar to intellectual property clauses in the constitutions of other countries, the US patent system has several peculiarities. Firstly, this clause is interpreted as giving the primary IP rights only to individuals (i.e. "inventors") rather than to organizations (see Stanford University v. Roche Molecular Systems, Inc.), Secondly, until 16 March 2013 the US gave priority to first inventors to invent, although the US adopted first inventor to file system since (see ). Thirdly, the US has provisional patent applications, which can be filed one year before filing regular patent application, thus delaying the start on the nominal 20 year patent term by one year. Fourthly, unlike most other countries, the US allows extension of patent monopoly beyond 20 years from the filing date via patent term adjustment due to the patent prosecution delays by the USPTO or due to product approval delays by Food and Drug Administration. Fifthly, the US does not have utility models. Sixly, there is no criminal liability for patent infringement in the US, only civil liability.

Patentability
Within the context of a national or multilateral body of law, an invention is patentable if it meets the relevant legal conditions to be granted a patent. By extension, patentability also refers to the substantive conditions that must be met for a patent to be held valid. The patent laws usually require that, for an invention to be patentable, it must be: Patentable subject matter, i.e., a kind of subject-matter eligible for patent protection Novel (i.e.
Inventive step and non-obviousness
The inventive step and non-obviousness reflect a general patentability requirement present in most patent laws, according to which an invention should be sufficiently inventive—i.e., non-obvious—in order to be patented. In other words, "[the] nonobviousness principle asks whether the invention is an adequate distance beyond or above the state of the art". The expression "inventive step" is predominantly used in Europe, while the expression "non-obviousness" is predominantly used in United States patent law.
Patent prosecution
Patent prosecution describes the interaction between applicants and their representatives, and a patent office with regard to a patent, or an application for a patent. Broadly, patent prosecution can be split into pre-grant prosecution, which involves arguing before, and sometimes negotiation with, a patent office for the grant of a patent, and post-grant prosecution, which involves issues such as post-grant amendment and opposition. Patent prosecution is distinct from patent litigation, which describes legal action relating to the infringement of patents.
