Appeal No. 2002-1578 Application No. 08/814,928 claimed invention. In our opinion, the Examiner's analysis is sufficiently reasonable that we find that the Examiner has at least satisfied the burden of presenting a prima facie case of obviousness. The burden is, therefore, upon Appellants to come forward with evidence and/or arguments which persuasively rebut the Examiner’s prima facie case of obviousness. Only those arguments actually made by Appellants have been considered in this decision. Arguments which Appellants could have made but chose not to make in the Brief have not been considered [see 37 CFR § 1.192(a)]. Appellants’ arguments in response to the obviousness rejection based on the combination of Leak and Terada assert that the Examiner has failed to establish a prima facie case of obviousness since all of the claimed limitations are not taught or suggested by the applied prior art references. After careful review of the applied Leak and Terada references in light of the arguments of record, we find Appellants’ assertions to be unpersuasive. In our view, Appellants’ arguments unpersuasively focus on the individual differences between the limitations of representative claim 31 and each of the applied references. It is apparent, however, from the Examiner’s line of reasoning in the Answer, that the basis for the obviousness rejection is the combination of Leak and Terada. One cannot show nonobviousness by attacking references individually 6Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
