Patents are generally believed to be the most territorial form of intellectual property. However, with the modernization of the world economy, there is a strong push against the traditional territorial limits of patent laws in the United States.
Patent infringement is defined by the statute in 35 USC. Section 271 (a) that provides: “Except as otherwise provided in this title, whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States, or imports into the United States any patented invention during the term of the patent therefor, infringes the patent.” Additionally, Sections 271(b) and 271(c) define indirect infringement, creating liability for contributing or inducing acts that constitute patent infringement in the United States. The terms “United States” and “this country” mean the United States of America, its territories, and possessions” [35 U.S.C 100 (c)].
