A method for reducing the haze in a conductive tin oxide
film on a substrate comprising:
providing a substrate having a conductive tin oxide
surface film;
providing a solution of a metallic oxide precursor in a
suitable carrier solvent;
coating said conductive tin oxide surface with said
coating solution by a wet chemical solution deposition process
to form a coating of a desired thickness; and
removing said solvent and converting said precursor to a
solid-state metal oxide film overlying said tin oxide surface.
The examiner relies upon the following reference as
evidence of obviousness:

Appellants’ claimed invention is directed to a method for
reducing the haze in a conductive tin oxide film that is
situated on a substrate. The method entails coating the
conductive tin oxide film with a solution of a metallic oxide
precursor, removing the solvent of the solution, and
converting the precursor to a solid-state metal oxide film
which overlies the tin oxide film.
Appellants submit at page 4 of the principal Brief that
claims 1-4, 11, 13-18 and 21-25 stand or fall together.
