Appeal No. 1997-0799
Application 08/242,235
Buzak focusses upon the relationship of the voltage levels
between adjacent electrodes within the plasma cell rather than
the relationship of electrodes from the plasma cell to
electrodes of the liquid crystal cell. The examiner's
position at the top of page 3 of the answer recognizes that
Buzak does not teach the driving circuit as recited in the
wherein clause at the end of claim 1 on appeal. Assuming for
the sake of argument that it would have been obvious for the
artisan to have combined the teachings of Iwama and Buzak,
Iwama teaches simultaneously inverting an image signal, the
anode potential and the drive voltage for the data signals.
To the extent the examiner may be possibly correct in
asserting that these teachings relate to substantially
eliminating an increase in voltage between the discharge
electrodes and the data electrodes, the reference Iwama does
not address changing the potentials during the application of
a discharge pulse which is required as well in the wherein
clause of claim 1 on appeal. Therefore, inasmuch as both
references fail to address the specific timing and voltage
