Application No. 08/496,121
signals applied to the input and gate electrodes of Ichimura’s
drive transistor QB be opposite in phase. Although we found
Appellant’s argument concerning Ichimura’s lack of disclosure
of a PMOS drive transistor to be without merit, we reach the
opposite conclusion regarding the opposite phase drive
transistor input signals. After careful consideration of the
Ichimura reference in light of the arguments of record, we are
in agreement with Appellant’s stated position in the Briefs.
As discussed supra, the Examiner has identified the signals
identified as waveforms NC and ND (Ichimura, Figures 1 and 2)
as corresponding to the first and second signals produced by
the claimed first and second potential means. It is apparent
to us, however, from the illustration in Figure 2 and the
accompanying description at columns 7 and 8 of Ichimura that
the signals NC and ND are not opposite in phase as claimed.
We note that the Examiner, in responding to this last
argument of Appellant and reiterating that Ichimura expressly
provides for substituting P-channel transistors for N-channel
transistors, asserts (Answer, page 9) the following:
