panned (horizontally scrolled) ways (col. 9, lines 12-14),
logarithmic scale (col. 9, lines 36-39) and time spectrum (col.
9, lines 49). However, we agree with Appellants (brief, page 11)
that the only altered display parameter in Moriyasu is the time
scale on the horizontal axis, and not any other parameters such
as the number of traces.
With respect to Examiner’s assertion that altering the
number of traces is well known according to the admitted prior
art (answer, page 5), Appellants argue that the admitted prior
art merely refers to either single-trace or dual-trace mode for
operating a digital oscilloscope (brief, page 12) and not
switching between the two modes while displaying a waveform by
stating that:
More importantly, this reference is to scopes operating in
the live mode. There is no suggestion whatsoever in
applicants’ disclosure that it is known that the number of
traces, or the waveform displayed on a given trace, can be
altered in freeze mode, and there is no support whatsoever
for the examiner’s contention that it would have been
obvious to do so.
In response, the Examiner concludes (answer, page 7) that:
[I]t should be noted that the various types of display
format of the acquired data as recited in the claims, such
as single-trace display mode or dual-trace display mode, are
well known in the art (either taught by Jonker or
applicant’s admitted prior art).
