Appeal No. 1998-2975
Application No. 08/790,250
972 F.2d 1260, 1266, 23 USPQ2d 1780, 1783-4 (Fed. Cir. 1992).
"There must be some reason, suggestion, or motivation found in
the prior art whereby a person of ordinary skill in the field
of the invention would make the combination." In re Oetiker,
977 F.2d 1443, 1447, 24 USPQ2d 1443, 1446 (Fed. Cir. 1992).
We find no such suggestion or motivation in the prior art
applied in this case. Consequently, the examiner has failed
to establish a prima facie case of obviousness, and we cannot
sustain the rejection of claims 12, 17, 18, 43, 51, and 52.
