DBC, LLC (“DBC”) appeals from a final decision of the United States Patent and Trademark Office Board of Patent Appeals and Interferences (“the Board”), which affirmed the examiner’s rejection of all pending claims as obvious under 35 U.S.C. § 103. Ex parte DBC, No. 2007-1907 (B.P.A.I. Aug. 24, 2007) (“Decision”). Because substantial evidence supports the Board’s determination that the claims would have been obvious, and because DBC has waived challenging the appointment of the administrative patent judges who presided over its appeal, we affirm.
