Appeal 2007-0005
Application 10/198,489
RFL adhesives such that it is comparable to the bond between nylon fibers
and rubber. Indeed, Fujiwara discloses that Japanese Patent Laid-Open No.
59-89375, which is also cited in Appellants’ Specification, discloses the use
of Appellants’ RFL adhesive solution, i.e., an aqueous mixture of a
chloroprene/dichlorobutadiene copolymer latex and resorcinol-formaldehyde
resin (See col. 1, ll. 45-49). Accordingly we are satisfied that one of
ordinary skill in the art would have gleaned from Fujiwara that it was known
in the art, or at least obvious, to bond nylon fibers to rubber with the
presently claimed adhesive composition.
Regarding the separate rejections over the additional references,
Iwami and Atwell, we concur with the reasoning set forth in the Examiner’s
Answer.
As a final point, we note that Appellants base 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.
In conclusion, based on the foregoing and the reasons stated by the
Examiner, the Examiner’s decision rejecting the appealed claims is affirmed.
