Diamond, Commissioner of Patents and Trademarks v. Diehr et al.
Case Date: 05/05/1981
|
Diamond v. Diehr, 450 U.S. 175 (1981), was a 1981 U.S. Supreme Court decision which held that the execution of a physical process, controlled by running a computer program was patentable. The high court reiterated its earlier holdings that mathematical formulas in the abstract could not be patented, but it held that the mere presence of a software element did not make an otherwise patent-eligible machine or process un-patentable. Diehr was the third member of a trilogy of Supreme Court decisions on the patent-eligibility of computer software related inventions.[1]
