Appeal No. 1997-4104
Application 08/383,238
melt viscosity of at least 54 kPoise. Thus, by defining their
PVDF polymer component as having a melt viscosity of at least
40 kPoise, appellants have inherently defined the composition
as a low gloss paint.
In finding the herein claimed invention obvious over the
teachings of Bacque, the examiner states in his answer at
pages 4 and 5 that this prior art reference relates to a
process for manufacturing vinylidene fluoride polymers and to
the use of these polymers in paints. A typical paint
formulation disclosed in the prior art Bacque reference at
column 4, lines 1-10 is comprised of a PVDF polymer, an
acrylic resin, a pigment, a solvent and an anionic surfactant.
The examiner further asserts that the disclosed amounts of
resin, pigment and solvents encompass those that are instantly
claimed and the examiner contends that it would have been
obvious to one of ordinary skill in this art to simply follow
the teachings of Bacque to arrive at the claimed invention.
The examiner further points out that since the claims on
appeal do not expressly specify a gloss value, it is
immaterial that Bacque’s primary purpose is to produce a paint
