Diamond Coating Techs., LLC v. Hyundai Motor Am., No. 15-1844 (Fed. Cir. 2016)
Annotate this CaseDiamond sued the auto companies, alleging infringement of its patents. The district court dismissed the actions finding that agreements between Diamond and Sanyo, the original assignee of the patents-in-suit, did not confer patentee status on Diamond, allowing Diamond to sue without joining Sanyo. The court later held that nunc pro tunc agreements executed by Diamond and Sanyo after its decision in Diamond did not affect its determination. The Federal Circuit affirmed. The original agreements did not convey all of the substantial rights in the patents to Diamond. Precedent bars consideration of the subsequent agreements.
