Diamond v. Diehr, 450 U.S. 175 (1981)

Case Description

The U.S. Supreme Court upheld a decision by the Court of Customs and Patent Appeals to grant a patent on a process using an abstract formula. It therewith held that an invention in the form of a process including an as such not patentable element is patent-eligible if it meets the requirements of patentability as a whole.
