Paul M. Ambrose and Crimora Research and Development Corporation v. John A. Marzall, Commissioner of Patents

181 F.2d 272, 86 U.S. App. D.C. 413

Opinion

PER CURIAM.

This appeal is from a judgment for the defendant Commissioner of Patents in,a suit under R.S. § 4915, 35 U.S.C.A. § 63, to obtain reissue of a patent with added claims. Quite apart from any question of estoppel, there was no substantial evidence of the “inadvertence, accident, or mistake” required by R.S. § 4916, 35 U.S.C.A. § 64. We express no opinion regarding the District Court’s ruling that the appellant was, as a matter of law, estopped to make the added claims.

Affirmed.
