Appeal No. 96-1501
Application No. 08/172,517
art. From our review of the patent to Matsumoto, we find that
Matsumoto discloses that polyolefin coatings may be applied to
containers "useful as packaging materials for foods, liquids, and
medicines" (column 4, lines 21-22) as has the examiner, but also
that it discloses that a method of applying a polyolefin coating
can include "adhering the polyolefin composition to the polar
material by electrostaticity and then melting the polyolefin
composition to laminate it on the polar material" (column 3,
lines 58-61), and that a primer may be used prior to such coating
(column 4, lines 5-7).
However, as with our discussion above with respect to the
rejection of claims 1 through 3, 5 and 6 under § 103 as being
unpatentable over Appellants' admitted prior art in view of
Walker, we fail to see how the process of forming the metal can
of Walker would have taught one of ordinary skill in the art to
utilize these teachings to coat the inside surface of elements of
containers, then premelt the polyolefin composition, then
assemble the elements, and then melt the polyolefin composition
again to arrive at the process recited in appealed claim 1. We
again conclude that the only reason to combine the teachings of
the applied prior art in the manner proposed by the examiner in
this rejection of claims 1 through 3, 5 and 6 under 35 U.S.C.
