IMPLICIT, LLC v. SONOS, INC., JOHN A. SQUIRES, UNDER SECRETARY OF COMMERCE FOR INTELLECTUAL PROPERTY AND DIRECTOR OF THE UNITED STATES PATENT AND TRADEMARK OFFICE
The Federal Circuit affirmed the Patent Trial and Appeal Board's decision that certificates of correction issued after final written decisions in inter partes review proceedings do not retroactively invalidate those decisions. The court held that the patent owner forfeited the right to rely on the corrected inventorship because it failed to raise the argument in a timely manner during the initial proceedings.
