Appeal No. 96-1669 Application 08/054,125 OPINION We will not sustain the rejection of claims 1, 3 through 6, 9 and 10 under 35 U.S.C. § 103. 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 obvi- ousness, the claimed invention should be considered as a whole; there is no legally recognizable 'heart' of the inven- tion." Para-Ordnance Mfg. v.
