Appeal No. 1998-0652
Application No. 08/188,417
polyvinylidene fluoride homopolymer, at least one
thermoplastic copolymer of vinylidene fluoride and a
plasticizer. Further details of this appealed subject matter
are set forth in representative independent claim 1 which
reads as follows:
1. A polymer composition consisting essentially of, by
weight:
(A) approximately from 60 to 80% of at least one PVDF
homopolymer;
(B) approximately from 20 to 40% of at least one
thermoplastic copolymer of vinylidene fluoride
and of at least one other fluoromonomer, present in
this copolymer in weight proportions of approximately
5 to 25% and
(C) approximately from 5 to 20%, relative to the total
weight of the polymers (A) and (B), of a monomeric or
polymeric plasticizer.
The reference set forth below is relied upon by the
examiner as evidence of obviousness:

The claims on appeal are rejected under 35 U.S.C. § 103
as being unpatentable over Budzinski.
