Appeal No. 2000-0482 Application 08/569,256 composition or device, or carry out the claimed process; and (2) whether the prior art would also have revealed that in so making or carrying out, those of ordinary skill would have a reasonable expectation of success. Both the suggestion and the reasonable expectation of success must be founded in the prior art, not in the applicant’s disclosure. In re Vaeck, 947 F.2d 488, 493, 20 USPQ2d 1438, 1442 (Fed. Cir. 1991)(citation omitted). The examiner relies on each of the primary references as disclosing a mold release composition comprising one or more of components A and C3 of the claimed invention. Examiner’s Answer, Paper No. 20, mailed July 27, 1999, page 3, paragraph (10). The examiner acknowledges that the primary references do not disclose component B, i.e., a polytetrafluoroethylene (PTFE) having a number-average molecular weight of 50,000 to 500,000. However, the examiner maintains that it would have been obvious to have used component B in the compositions of the primary references in view of Wagner which discloses a PTFE release agent having a molecular weight of 30,000 to 200,000. 3 3See claim 1 for recitations of components A, B and C. 4Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
