Appeal 2007-4097
Application 09/792,776
Claim 1 is illustrative:
1. A method of preparing an [sic, a] thermoplastic resin composition
comprising:
obtaining a crosslinked softening agent composition by blending and
heat treating the components consisting essentially of
(a) 100 parts by weight of at least one non-aromatic hydrocarbon
softening agent for rubber;
(b) 0.1 to 10 parts by weight of an organic peroxide; and
(c) 0.1 to 50 parts by weight of a crosslinking aid, wherein the weight
ratio of component (b) to component (c) is 1 or less; and
blending the crosslinked softening agent composition with 1 to 1500
parts by weight of a thermoplastic resin relative to 100 parts by weight of the
crosslinked softening agent composition.
The Examiner relies upon the following references:

Tasaka US 5,929,165 Jul. 27, 1999
Appealed claims 1-9 stand rejected as unpatentable as follows:
(i) claims 1-9 are rejected under 35 U.S.C. § 102(b) as anticipated by or, in
the alternative, under 35 U.S.C. § 103(a) as obvious over Tasaka ; and
(ii) claims 1-9 are rejected under 35 U.S.C. § 102(b) as anticipated by or, in
the alternative, under 35 U.S.C. § 103(a) as obvious over Hamanaka.
We have thoroughly reviewed each of Appellants’ arguments for
patentability. However, we are in full agreement with the Examiner that the
claimed subject matter is unpatentable over the cited prior art. Accordingly,
