Appeal No. 1998-2815 Application No. 08/648,790 commentary with regard to the above-noted rejection and the conflicting viewpoints advanced by the examiner and appellants regarding the rejection, we make reference to the final rejection (Paper No. 5, mailed April 18, 1997) and the examiner's answer (Paper No. 9, mailed October 21, 1997) for the reasoning in support of the rejection, and to appellants' brief (Paper No. 8, filed September 2, 1997) for the arguments thereagainst. OPINION In reaching our decision in this appeal, we have given careful consideration to the appellants' specification and claims, to the applied prior art references, and to the respective positions articulated by the appellants and the examiner. In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden of presenting a prima facie case of obviousness (see In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956 (Fed. Cir. 1993); In re Oetiker, 977 F.2d 1443, 4Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
