1Opinion of the Court
PAULINE NEWMAN, Circuit Judge.
Sonnie J. Perkins appeals the decision of the United States Patent and Trademark Office Board of Patent Appeals and Interferences (“the Board”), which held that neither party to an interference proceeding between Perkins and Phil Kwon was entitled to a patent. 1 The Board held Kwon to be the prior inventor, and cancelled the claims of Perkins’ previously granted patent. 35 U.S.C. §§ 102(g) and 135(a) (1982 & Supp. V 1987). The Board also held that the count was unpatentable to Kwon because of an on-sale bar. 35 U.S.C. § 102(b) (1982).
