Oyster Optics, LLC v. Infinera Corp., No. 19-2179 (Fed. Cir. Feb. 11, 2021)

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.

This case presents a narrow question of contract inter- pretation. The parties dispute whether a license and re- lease granted by Appellant to an entity and i ts “Affiliates” apply to Appellee, barring Appellant’s claims of patent in- fringement. We conclude that at least the license applies to Appellee, and, additionally, that the license is retroac- tive. Accordingly, we affirm the district court’s judgment in favor of Appellee.
