claimed invention. Additionally, Appellants assert that unlike
Jonker, Moriyasu cannot display engine waveforms with engine
sweeps since digitizing and memory means which can capture per-
cylinder data are missing in Moriyasu (brief, page 8). In
particular, Appellants point to the claimed freeze control
routine “for reconfiguring a frozen screen display format by
altering the number of traces and/or the assignment of plural
signals to plural traces” and indicate that neither reference
mentions plural scope traces (brief, page 11). With respect to
changing the display format of Moriyasu, Appellants argue that
the only change is made to the time base or the horizontal axis
of the displayed waveform (id.). Appellants dispute the
Examiner’s contention that once the waveform is digitized and
stored, it would have been obvious to alter a waveform in freeze
mode to any previously-known live format (brief, pages 12 & 13).
In response, the Examiner merely indicates that the
digitized and stored digital representation of a signal allows
“the display, comparison, and manipulation of the acquired signal
flexibly” (answer, page 6). The Examiner does not specifically
point to any relevant teachings in the prior art that relate to
reconfiguring a frozen screen display format by altering plural
frozen display traces.
