Appeal No. 1998-3364
Application No. 08/347,990
at 1551, 1553, 220 USPQ at 311, 312-13. In addition, our
reviewing court requires the PTO to make specific findings on
a suggestion to combine prior art references. In re
Dembiczak, 175 F.3d 994, 1000-01, 50 USPQ2d 1614, 1617-19
(Fed. Cir. 1999).
Upon our review of the references, we fail to find that
one of ordinary skill in the art who sets out to solve the
problem and who had for him in his workshop the Windsor system
and the Fung system would have reasonably expected to modify
the Fung computer system into a hand-held data entry unit and
then further modify Fung by looking to the Windsor pushless
run bar which employs two capacitive sensors for detecting the
placement of both operator's hands to obtain the Appellant's
invention. In particular, we note that Windsor teaches in
column 1, lines 10 through 16, that the Windsor system relates
to operator stations having two control devices mounted on a
common enclosure which must be actuated by two hands. Windsor
further discloses in column 1, lines 18 through 37, that Fig.
1 shows the type of run bar which is to be used with automatic
machinery such as mechanical or hydraulic power presses,
