Abbott v. Shepherd
Court of Appeals for the D.C. Circuit

1Opinion of the Court
RUTLEDGE, Associate Justice.
The suit is pursuant to Rev.Stat. § 4915 (1878), 35 U.S.C. § 63 (1940), to obtain letters patent. The only question is priority of invention, which in turn depends upon reduction to practice and diligence. In interference proceedings the Patent Office, through the Board of Appeals, awarded priority to Shepherd,1 although the Examiner of Interferences previously had found in favor of Abbott. The District Court also decided for Shepherd, on both diligence and reduction to practice, and accordingly dismissed Abbott’s complaint. He now appeals.
