in coating compositions, such as Campbell’s branched polymers,
some of which have polydispersities greater than 15 (abstract;
col. 8, lines 43-44; tables 1, 3 and 7).
Cleary discloses aqueous dispersions of polymers which are
made by reacting a monoethylenically unsaturated monomer with a
multiethylenically unsaturated monomer and can be used to make
printing ink binder resins or overprint varnishes as well as
other coating compositions (abstract; col. 3, lines 57-60;
col. 8, lines 48-56). This disclosure would have fairly
suggested, to one of ordinary skill in the art, using
monoethylenically unsaturated monomers and multiethylenically
unsaturated monomers which were known to be suitable in making
polymers for coating compositions, such as those of Campbell
which produce branched polymers, some of which have
polydispersities greater than 15 (abstract; col. 8, lines 43-44;
tables 1, 3 and 7).
The appellant argues that Campbell is nonanalogous art and
that the evidence in the second Gelarden declaration and the
Oberski declaration overcomes any prima facie case of obviousness
of claim 26 over Tutt or Cleary, in view of Campbell (brief,
pages 25-26). These arguments are not convincing for the reasons
given above regarding the rejection of claim 23.
