Appeal No. 2000-2188 Page 12
Application No. 09/063,050
Data Sys. Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir.
1984).
After reviewing the description of the admitted prior art
and in view of our analysis above, we agree with the Examiner
that “a first means for receiving an externally applied clock
signal” reads on pump controller 20 of Figure 1. The “externally
applied clock signal” reads on signal OSC in Figure 1 which is
externally applied to a pump controller and is outputted by the
oscillator, which in turn, constitutes a source that is external
to the pump controller. We further find that the prior art
voltage generator of Figure 1 includes an internal oscillator
outputting an internal oscillation signal OSC and a pump
controller that receives the internal oscillation signal and an
external control signal (specification, page 1, lines 11-15).
Although the source of the oscillation signal is defined as being
internal to and a part of the voltage generator, the oscillator
is external to the pump controller and its OSC output signal is
generated outside the pump controller.
In view of our analysis above, we find that the prior art of
Figure 1 discloses all the limitations of Appellants’ claims 1
and 4. We are further unpersuaded by Appellants’ assertion that
the Examiner incorrectly equated an output of an oscillator with
