motivation to combine the references, and that there is no
showing that it would provide a reasonable expectation of
success. We note that Prioste was relied upon for its teaching
of bit shifting with sign and zero extension. We also find that
Prioste provides adequate motivation for combining its teachings
with that of Groves. Particularly, at column 1, lines 42-44,
Prioste indicates that its suggested approach increases the
processing time of the data and reduce the cost of circuitry used
for shifting. Therefore, the combination of Groves and Prioste
was proper and would thus provide a reasonable expectation of
success.
It is our view, after consideration of the record before us,
that the evidence relied upon and the level of skill in the
particular art would have suggested to one of ordinary skill in
the art the invention as set forth in dependent claims 3-10,
13-20 and 23-33. Accordingly, we will sustain the Examiner’s
rejection of claims 3-10, 13-20 and 23-33 over the combination of
Groves and Prioste.
