rewriting operation. Each mismatch is recorded. However, the
search operation also occurs through the entire address region of
the mismatch memory to determine the lines to be changed. Thus,
even this prior art approach in Kaneko indicates that each pixel
is consecutively accessed twice by the same polarity of potential
difference in contrast to that which is required at the end of
independent claim 1 on appeal.
On the other hand, with respect to Kaneko’s contribution to
the art in his Figures 1 to 4, it is noted that the mismatch
signals are generated for incoming or refresh data as compared to
current data only on lines where data is to be displayed where a
mismatch has been detected. Therefore, only those lines would be
refreshed to indicate the changed data. However, appellants’
position throughout the various briefs, in our view, is correct
in that essentially some pixels will be consecutively accessed
twice by the same polarity of potential difference in contrast to
that which is required at the end of claim 1 on appeal for those
lines of Kaneko’s contribution where the mismatch has been
detected. A four by six dot or pixel exemplary display in Figure
3 of Kaneko indicates that in Figure 3c the mismatch line memory
has three of the four lines with mismatched data in them. This
indicates that the state of some pixels or dots within those
