Appeal No. 2004-2233
Application No. 10/100,331
Michels describes an aqueous dispersion (i.e., a latex) obtained
by polymerizing 62 parts by weight of CH 2=CHCOOCH2CH2C8F17, 15
parts by weight of n-butyl acrylate, 20 parts by weight of
CH2=CCH3COO(CH2CH2O)8H, and 3 parts by weight of
dimethylaminoethyl methacrylate in 285 parts by weight of
acetone; mixing with a solution of 3.9 parts of acetic acid in
296 parts by weight of deionized water; and then removing the
acetone by distillation at 60ºC and 200-300 mbar. (Examples 1
and 2.) The fluorine-containing monomer described in Michels is
encompassed by either the “non-aromatic unsaturated mono- or
dicarboxylic ester monomers” or “monomers containing ethylene
unsaturation” recited in appealed claim 1. (Specification, page
3, line 17 to page 4, line 2.) Additionally, the n-butyl
acrylate and the dimethylaminoethyl methacrylate described in
Michels are identified in the present specification as suitable
noncationic ethylenically unsaturated monomer and cationic
quaternary amine monomer, respectively. ( Id. at page 3, line 24
and page 4, lines 24-25.)
Thus, we share the examiner’s view that Michels describes
each and every limitation of the invention recited in appealed
claim 1. In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d 1429,
1431 (Fed. Cir. 1997).
