On April 25, 2016, the Court of Appeals for the Federal Circuit affirmed the judgment of invalidity on two patents in favor of Knobbe Martens client Toshiba Corporation. The ruling came after two earlier jury verdicts against other defendants upheld the validity of the patents.  U.S. Ethernet Innovations had sued over 30 defendants for infringing these patents directed to Ethernet technology. This week’s affirmance brings an end to this seven year case.
