Appellee, alleging unlawful denial of his patent application by the Patent Office, petitioned the District Court, under 35 U.S.C. § 145, to authorize issuance of the patent by the Commissioner. Although finding that “some doubt exists as to the utility” of appellee’s claimed invention, the trial court, citing Application of Nurkiewicz, 338 F.2d 1020, 1022, 52 C.C.P.A. 848,- (1964), as its authority, resolved the doubt in favor of the applicant and ordered the Commissioner to grant the patent. Aghnides v. Reynolds, D.D.C., 241 F. Supp. 280 (1965). In so doing the trial court erred. Whatever may be the rule in patent review proceedings before the United States Court of Customs and Patent Appeals, in trials de novo under 35 U.S.C. § 145 in the District Court, “doubt [as to patentability] is to be resolved,” not in favor of the applicant, but “in favor of the correctness of administrative * * * action.” General Motors Corporation v. Coe, 74 App.D.C. 189, 190, 120 F.2d 736, 737, cert. denied, 314 U.S. 688, 62 S.Ct. 302, 86 L.Ed. 550 (1941). See also Stieg v.
