Appeal No. 1998-0493 Application 08/364,000 After a careful review of the evidence before us, we will not sustain the rejection of claims 1 through 6 under 35 U.S.C. § 103. At the outset, we note that Appellant has indicated on page 4 of the brief all claims stand or fall together with claim 1. The Examiner has failed to set forth a prima facie case. It is the burden of the Examiner to establish why one having ordinary skill in the art would have been led to the claimed invention by the reasonable teachings or suggestions found in the prior art, or by a reasonable inference to the artisan contained in such teachings or suggestions. In re Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6 (Fed. Cir. 1983). "Additionally, when determining obviousness, the claimed invention should be considered as a whole; there is no legally recognizable 'heart' of the invention." Para-Ordnance Mfg. v.
