Use of an Invention: 'Anticipating'?
Under U.S. patent law, an inventor is entitled to a patent if the invention is useful, novel, and nonobvious. The "novelty" prong of this tripartite test is controlled by 35 U.S.C. '102, which defines the "prior art" (<i>ie,</i> already existing technology) that can "anticipate," or render non-novel, the invention. In general, an invention sought to be patented is anticipated when it already exists in the prior art, having been placed there either by a third party or through the inventor's own actions. Under '102, prior use of the invention can anticipate a patent in certain circumstances. Specifically, the statute states that: "A person shall be entitled to a patent unless (a) the invention was ... used by others ... before the invention thereof by the applicant ...; or (b) the invention was ... in public use ... more than one year prior to the date of the application.
