Appeal No. 95-3285
Application 07/984,427
three lines must be changed since Kaneko’s contribution operates
on a line by line basis. Therefore, it appears that appellants’
basic position that in this situation if any single pixel within
that whole line is identical with the equivalent single pixel or
dot in the corresponding whole line of data existing prior to the
change, then the writing of the whole line into the display will
inevitably produce the result that such a single pixel will be
accessed for a second consecutive time by the same polarity of
potential difference. Since Kawakami is not concerned with any
such comparisons or data refresh operations, this secondary
reference fails to cure the deficiencies with respect to Kaneko
as their combined teachings relate to the subject matter of
independent claim 1 on appeal.
Furthermore, Kaneko’s display appears to us to be discussed
in terms of a general LCD-type display. Therefore, it cannot
be said that it is polarity sensitive. Similarly, as noted by
appellants at page 3 of the reply brief, Kawakami’s display is
also not polarity sensitive but, in our view, is amplitude
voltage sensitive based upon the combined values of the bias
and signal voltages according to the addressing scheme in each
embodiment in Kawakami. Thus, there appears to be a complete
absence among the combined teachings of the references as to any
