Cioffi v. Google LLC, No. 18-1049 (Fed. Cir. Apr. 18, 2023)

From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

The plaintiffs-appellees (collectively, “Cioffi”) brough t this patent infringement action against defendant -appel- lant Google LLC, alleging infringement of a total of four claims across three patents. Following a trial, the jury found the asserted claims to be infringed and not invalid. The district court then addressed the question whether the asserted claims were invalid under 35 U.S.C. § 251 and held that they were not. We reverse the district court’s de- termination that the claims were not invalid.
