A Patent Determination occurs when a court or administrative agency issues a decision that determines the infringement, validity (or patentability), or enforceability of one or more claims of a patent. There may be more than one determination per patent and determinations may be overturned or reversed in later proceedings. Determinations may be made in connection with a stipulation or agreement of the parties, but many searches allow for the exclusion of such determinations if desired. Determinations are recorded by patent number, not individual claims.
