Appeal No. 1999-2720 Application No. 08/580,965 OPINION We will not sustain the rejections of claims 1-9 under 35 U.S.C. § 103. We first consider the rejection of claims 1-4 and 7. 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 express teachings or suggestions found in the prior art, or by implications 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.
