2173.05(v) Mere Function of Machine - 2100 Patentability
2173.05(v) Mere Function of Machine
Process or method claims are not subject to rejection by U.S. Patent and Trademark Office examiners under 35 U.S.C. 112, second paragraph, solely on the ground that they define the inherent function of a disclosed machine or apparatus. In re Tarczy-Hornoch, 397 F.2d 856, 158 USPQ 141 (CCPA 1968). The court in Tarczy-Hornoch held that a process claim, otherwise patentable, should not be rejected merely because the application of which it is part discloses apparatus which will inherently carry out the recited steps.
