Appeal No. 1997-4442 Application 08/353,040 Appellants also argue that de Wit does not mention trimming, whereas claim 6 recites that the first and second path portions are trimmed so that the resistor has a desired resistance value and a desired TCR (Br6; RBr2 n.1). The Examiner responds that "[t]rimming resistors to achieve a desired value is extremely old and well known in the art and one of ordinary skill in the art would [have] realize[d] that trimming may be done on the resistor of de Wit" (EA5). That something "may" be done does not establish inherency necessary for anticipation. Inherency requires a certainty that an undisclosed function or characteristic is necessarily present. "The mere fact that a certain thing may result from a given set of circumstances is not sufficient [to establish inherency.]" In re Oelrich, 666 F.2d 578, 581-82, 212 USPQ 323, 326 (CCPA 1981) (citations omitted) (emphasis added). Thus, the anticipation rejection of claims 6 and 2 based on de Wit is reversed for the additional reason that there is no teaching of trimming.
