Appeal No. 96-3851
Application No. 08/341,849
Deutsch deals with a method for forming an analytic model
of an image, and has nothing to do with inkjet printing a
color
image. Sugiura is concerned with determining a recording area
factor for each color, including black, and does not teach why
one of ordinary skill in the art would want to print both
black and color at the same pixel in a device such as
Vaughn's. In fact, Sugiura states (column 13, lines 52-53)
that "[b]lack ink k must be printed so as not to overlap inks
of other colors in low density images." Also, Vaughn shows
black separate from all colors in each figure depicting area
factors of color and black inks (see Figures 21, 29, 31, and
35). Accordingly, neither Deutsch nor Sugiura overcomes the
deficiencies of Vaughn. Therefore, we cannot sustain the
obviousness rejection of claim 4 and its dependents, claims 17
through 29. Further, since claim 32 includes the same
limitation of being capable of printing both black and color
ink at the same pixel, we also will reverse the obviousness
rejection of claim 32 and its dependents, claims 33 through
40.
