Appeal No. 2001-0740
Application 09/054,415
Appellants argue that Wang does not teach providing
"relatively high power to an active element during at least one
portion of an amplifier's operational cycle and to provide
relatively low power otherwise" as required by claim 1 (Br13).
The examiner states that high power 4I is applied during one
part of an operational cycle, i.e., when resolution control is
16, and low power I and 2I is applied otherwise (EA17).
The examiner interprets "an amplifier's operational cycle"
as the time when the overall device is operating. Appellants do
not respond to this interpretation. We agree with the examiner
that an "operational cycle" is broad enough to read on the time
when a circuit is in operation. Claim 1 does not require the
high power to be applied 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 during operation and relatively low power 2I
or I is applied otherwise. The rejection of claims 1-4 over Wang
is sustained.
Claim 9
Appellant argues that Wang does not show "a power control
circuit having two output levels connected to said active element
and selectively providing one of said levels to said element only
