Appeal No. 2001-0740
Application 09/054,415
show error in the examiner's findings. Accordingly, the
rejection of claim 17 is sustained.
Claim 18
The examiner finds that "[c]urrent sources 67D-67F and
68D-68F are selectively activated/deactivated during the
operational cycle of amplifier 5" (FR10).
As noted in connection with claim 13, appellants argue that
the examiner is factually incorrect because "[t]hose current
sources are activated as part of the resolution selection process
and are done manually by a user according to column 4,
lines 17-23" (Br15). Appellants assert that Wang does not show
"at least two sources of current to said active element in which
one of the sources is selectively activated during at least one
portion of an amplifier's operational cycle and inactive
otherwise" as recited in claim 18 (Br15).
As noted in connection with claim 1, we agree with the
examiner that an "operational cycle" is broad enough to read on
the time when a circuit is in operation. Claim 18 does not
require one of the sources to be activated at any specific time
during the cycle; e.g., a time when slew is expected. Appellants
do not contest that Wang discloses the user selecting different
resolutions at different times during operation, so the high
power current 4I is applied at some time using one of the sources
