Appeal No. 1997-1197
Application 08/130,255
apparatus for rotating image data in read [sic, real] time
with a small capacity memory" (EA4). The Examiner further
found with respect to claims 13 and 14 that it is conventional
in the art to use three bits per pixel for color flat panel
displays (FR4), which finding is not challenged by Appellants.
Appellants argue that Okazawa does not disclose repeating
sub-sequences of pixel data or keeping the sub-sequences in
the same order regardless of the image rotation so that the
three-bit output properly drives red, green, and blue
subpixels for a non-rotated as well as rotated image (Br19-
21).
The Examiner responds that the claims do not recite
keeping the bits of the sub-sequence in order. We agree as to
claims 13 and 14 and disagree as to claims 18 and 19.
Okazawa discloses a dot matrix memory where pixels are
stored as an n n dot unit, e.g., in figure 4A, n=3, and "1, 2,
3, 4, 5, 6, 7, 8, and 9" indicates a specific picture element.
Okazawa provides hardware to rotate the 3 3 dot unit.
Claims 13 and 14 merely require that a group of bits in
the first read sequence is used to represent a pixel. In our
opinion, it would have been obvious to one of ordinary skill
