Appeal No. 2001-0740
Application 09/054,415
Claim 10
The examiner finds that current sources 67D, 68D of Fig. 2
is active during relatively low operation phases and current
sources 67E, 67F, 68E, 68F are activated during higher
operational phases, thus anticipating claim 10 (FR9-10).
Appellants' asserts that Wang does not show "an active
element, connected to said current sources so that only one
current source is active during an operation phase when power
requirements are relatively low and so that both current sources
are active during an operational phase when power requirements
are relatively high" as recited in claim 10 (Br13-14).
The examiner finds that one current source is active when a
low power requirement (e.g., I or 2I) is required and at least
two current sources are active when high power requirements
(i.e., 4I) are required (EA17).
Wang teaches two current sources that are active under
different power requirements as set by resolution select
input 17. Claim 10 is broad and does not positively recite that
the conditions of "when power requirements are relatively low"
and "when power requirements are relatively high" are determined
automatically or occur during a part of a cycle. The user can
determine when the power requirements are high and low.
Therefore, claim 10 does not define over Wang's teaching of a
user setting the resolution select input 17 to provide a low
