Finjan LLC v. Eset, LLC, No. 21-2093 (Fed. Cir. Nov. 1, 2022)

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.

Appellant Finjan, Inc. appeals the U.S. District Court for the Southern District of California’s grant of summary judgment of invalidity. The district court construed the claim term “Downloadable” in the asserted patents to be restricted to “small” executable or interpretable applica- tion programs based on the definition of “Downloadable” provided by a patent in the same family that was incorpo- rated by reference into the asserted patents. The district court determined that the asserted claims were indefinite and thus invalid.
