Appeal 2006-2472
Application 10/451,098
adding natural resin pellets to the plastic pigment particles within the
high-intensity mixer; and
mixing the plastic pigment particles and natural resin pellets in the
high-intensity mixer at a high shear rate in the absence of added heat energy,
to cause a coating of colored plastic to fuse to the surfaces of the natural
resin pellets.
The Examiner relies upon the following reference as evidence of
obviousness:
Hurley US 5,919,530 Jul. 6, 1999
Appellant’s claimed invention is directed to a process for preparing color
coated plastic pellets. The process entails dispersing pigment in a polymeric
carrier with a high-intensity mixer in the absence of added heat energy and adding
resin pellets to the pigmented plastic with the high-intensity mixer. The pigmented
plastic is mixed with the resin pellets in the absence of added heat energy which
causes the pigmented plastic to fuse on the surface of the resin pellets.
Appealed claims 1-10 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Hurley.
Appellant fails to present arguments that are reasonably specific to any
particular claim on appeal. Accordingly, all the appealed claims stand or fall
together with claim 1.
We have thoroughly reviewed each of Appellant’s arguments for
patentability. However, we are in complete agreement with the Examiner that the
claimed subject matter would have been obvious to one of ordinary skill in the art
