Appeal No. 97-1260
Application 08/124,774
furnished the artisan with ample suggestion or motivation to
provide the licker-in or breaker roll B with a sawtooth
clothing and the breaker roll A with a pin clothing when
combined with Otani’s teaching of a main carding cylinder
having a sawtooth clothing and revolving flats or tops having
a pin clothing. That Riehl discloses a conventional pin
clothing construction has not been disputed. The relative
clothing point density argument advanced by the appellant is
unpersuasive in light of the lack of any express mention of
this feature in the claims, or even in the underlying
disclosure, and the lack of any evidence in the record
supporting the appellant’s assertion that this feature
inherently is recited in the claims.
In light of the foregoing, the differences between the
subject matter recited in representative claim 1 and the prior
art are such that the subject matter as a whole would have
been obvious at the time the invention was made to a person
having ordinary skill in the art. Accordingly, we shall
sustain the standing 35 U.S.C. § 103 rejections of this claim
and of dependent claims 2 through 15, 17 through 19, 21 and 22
which stand or fall therewith.
