Appeal No. 95-4544 Application 07/975,905 Upon a careful review of Jakobs, we fail to find that the references teach the above limitations as recited in Appellant's claim 1. The Examiner argues that these limitations are well known in the art to the skilled artisan. However, the Examiner has not provided a reference or an affidavit as evidence of these statements. We are not inclined to dispense with proof by evidence when the proposition at issue is not supported by a teaching in a prior art reference, common knowledge of unquestionable demonstration. Our reviewing court requires this evidence in order to establish a prima facie case. In re Knapp-Monarch Co., 296 F.2d 230, 232, 132 USPQ 6, 8 (CCPA 1961); In re Cofer, 354 F.2d 664, 668, 148 USPQ 268, 271-72 (CCPA 1966). Furthermore, we fail to find any suggestion of modifying Jakobs to provide a computer file editing system as recited in Appellant's claim 1. The Federal Circuit states that "[t]he mere fact that the prior art may be modified in the manner suggested by the Examiner does not make the modification obvious unless the prior art suggested the desirability of the modification."
