8080467

Patent record lists this as the sole litigation entry for US 7,442,629, but the accessible court records indicate the patents asserted were US 8,680,591, US 8,080,467, and initially US 7,884,446, a divisional of US 7,442,629. A May 2019 jury found willful infringement of the '467 patent and breach of the parties' NDA; the September 24, 2019 judgment granted SiOnyx ownership of disputed Hamamatsu patents and a permanent injunction, and the related appeal closed on 2021-05-18.

Unified Patents filed an inter partes review petition challenging U.S. 8,080,467. The PTAB did not institute the proceeding, denying it on the merits without a final written decision.

Federal Circuit appeal from the District of Massachusetts judgment in the '467 patent case. The court affirmed the infringement/ownership rulings as to disputed U.S. patents, declined to reach willfulness, reversed the denial of sole ownership of disputed foreign patents and remanded to compel their transfer to SiOnyx, and affirmed denial of § 285 fees.

SiOnyx appealed the D. Mass. judgment in its case against Hamamatsu. The Federal Circuit affirmed the ownership award, injunctions, damages, and interest awards, but reversed the refusal to compel transfer of foreign patents and remanded.
