Appeal No. 96-2682
Application 08/145,269
teaches in column 3, lines 33-43, an electrode lead for a lamp
comprised of an alloy of tungsten and molybdenum.
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). In
addition, the Federal Circuit states that "[t]he mere fact that
the prior art may be modified in the manner suggested by the
Examiner does not make the modification obvious unless the prior
art suggested the desirability of the modification." In re
Fritch, 972 F.2d 1260, 1266 n.14, 23 USPQ2d 1780, 1783-84 n.14
(Fed. Cir. 1992), citing In re Gordon, 733 F.2d 900, 902,
221 USPQ 1125, 1127 (Fed. Cir. 1984).
"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. SGS Importers Int’l, Inc., 73 F.3d 1085, 1087, 37 USPQ2d
1237, 1239 (Fed. Cir. 1995), cert. denied, 117 S.Ct. 80 (1996),
citing W. L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d
