both Otsuka and Kaijou are directed to organic solvent-based
compositions. See appeal brief, pages 5-6. In this regard,
appellants note that “it is well understood that components
useful in solvent-based systems may not necessarily perform or be
compatible in a water-based system.” Id., page 5.
Responsive to appellants arguments, the examiner points out
that Quintens clearly teaches that organic solvents can be
included within the aqueous dispersion for the purpose of
improving coherence and film-forming capability. Examiner’s
answer, pages 4-5 (referencing Quintens, column 6, lines 32-56).
Quintens teaches that
[s]uitable polymeric polyanion compounds for use
in the presence of said polythiophenes prepared by
oxidative polymerization are acidic polymers in free
acid or neutralized form. . . .
. . . .
Instead of the free polymeric polyacids applied in
conjunction with the polythiophenes it is possible to
use mixtures of alkali salts of said polyacids and non-
neutralized polyacids, optionally in the presence of
monoacids.
Quintens, column 5, lines 14-17 and 47-51 (emphasis added). See
examiner’s answer, page 3, second paragraph. The examiner
maintains that, “in order to determine the specific monoacids
that may be used in [Quintens] composition, one skilled in the
