Appeal No. 2005-0581
Application No. 10/228,124
assignee, Xerox Corporation, appellant is in the position of
establishing of record that proline is effective as an ink drying
agent only when exposed to microwave radiation. Furthermore,
even if this was the case, it would have been obvious for one of
ordinary skill in the art to expose the coating of Miyabe to
microwave radiation in order to bring about the known ink drying
effect.
Appellant also submits that "[a]dditives in inks and
additives in recording sheet coatings have different
requirements, such as compatibility with the other ingredients of
the ink or coating" (page 3 of Reply Brief, second paragraph).
However, appellant has pointed to no particular property of
proline that would have made it unsuitable for the coating layer
of Miyabe. In our view, one of ordinary skill in the art would
have had to resort to only routine experimentation to determine
if a known ink drying agent is unsuitable for Miyabe's coating
layer.
As a final point, we note that appellant bases no argument
upon objective evidence of nonobviousness, such as unexpected
results, which would serve to rebut the prima facie case of
obviousness established by the examiner.
