Diamond v. Diehr
United States Supreme Court
450 U.S. 175 (1980)
Relevant factsFree
Diehr's (applicant's) patent application for a rubber-curing process incorporating the Arrhenius equation was rejected by the patent examiner as directed to an unpatentable mathematical formula, but the Court of Customs and Patent Appeals reversed; the Commissioner of Patents (petitioner) sought Supreme Court review.
IssueFree
Whether having a mathematical formula in a method claim itself renders the claim unpatentable under 35 U.S.C. § 101.
