Komatsu, on the other hand, discloses a color-converting
system for forming CMY color images from RGB color data using an
interpolation method (col. 1, lines 27-32). However, the
interpolation operation of Komatsu reduces the number of lattice-
point output values in order to conserve the memory capacity
(col. 2, lines 45-47). Therefore, although the dividing
information for generating the converted lattice-point output
values is stored in a RAM, as pointed out by Appellants (brief,
page 12), Komatsu provides no teachings related to adding to the
number of lattice-point values in the process of converting color
data of one color space to that of a different color space.
Thus, assuming, arguendo, that it would have been obvious to
combine Bhattacharjya with Komatsu, as held by the Examiner, the
combination would still fall short of teaching a process for
generating a color conversion table used for converting printing
data from a gray scale color space to the data of a different
color space based on a smaller number of lattice points in a pre-
conversion table. We note that, similar to claim 45, independent
claims 51 and 57 recite a conversion table for converting color
data from one color space to another color space. Therefore, as
the Examiner has failed to set forth a prima facie case of
