Appeal No. 1997-1185
Application No. 08/497,845
OPINION
After a careful review of the evidence before us, we
will not sustain the rejection of claims 1 through 19 under
35 U.S.C. § 103.
The Examiner has failed to set forth a prima facie

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.
