Appeal No. 2001-0127
Application No. 09/121,636
The subject matter on appeal relates to a polymer
composition (claims 1-5) and to a "method for improving the
burnish response of a floor polish composition" comprising using
the polymer composition in the floor polish composition (claims
6-10). Further details of this appealed subject matter are
recited in illustrative claims 1 and 6 reproduced below:
1. A polymer composition comprising an aqueous
suspension or dispersion of a water insoluble polymer
of ethylenically unsaturated monomers, said polymer
having a Tg of at least 35°C and comprising 25% to 65%
by weight units of isobutyl methacrylate (IBMA) and
butyl methacrylate (BMA) and 3% to 50% by weight units
of at least one acidic monomer.
6. A method for improving the burnish response
of a floor polish composition, which method comprises
using in the floor polish composition an aqueous
suspension or dispersion of a water-insoluble polymer
of ethylenically unsaturated monomers, said polymer
having a Tg of at least 35°C and comprising 25% to 65%
by weight units of IBMA and BMA, and 3% to 50% by
weight units of at least one acidic monomer.
The examiner relies on the following prior art reference as
evidence of unpatentability:
Anton et al. 5,798,426 Aug. 25, 1998
(Anton) (effective filing date May 10, 1996)
Claims 1 through 10 on appeal stand rejected under 35
U.S.C. § 103(a) as unpatentable over Anton. (Final Office
purposes of this appeal. We note, however, that the amendment
has not been clerically entered.
