SRI International v. Matsushita Electric Corp. of America

United States Court of Appeals for the Federal Circuit
775 F.2d 1107, 227 U.S.P.Q. 577 (1985)

Facts

SRI International (SRI) (plaintiff) held a patent on a filter for recording and reproducing color in photographic images. SRI sued Matsushita Electric Corporation of America and Matsushita Electric Industrial Company, Ltd. (collectively, MEI) (defendants) in federal district court, alleging infringement of the filter in a camera sold by MEI. The court found that the structure of MEI’s camera and filter fell within the wording of SRI’s claims but that MEI’s product nevertheless operated to encode color in a fundamentally different way. Although these potential differences in operation remained a matter of factual dispute at trial, the court granted summary judgment in favor of MEI. SRI appealed to the United States Court of Appeals for the Federal Circuit.
