Appeal No. 1999-0787
Application No. 08/813,953
The claimed invention is a method for making a metal oxide
film by subjecting a hydrolyzable organic metal compound to
hydrolysis in a recited solution followed by dehydration and
condensation to obtain a reaction product, and then applying the
reaction product to a surface and maintaining the reaction
product at a temperature of 200ºC or below to form the metal
oxide film.1
The examiner argues that the appellant’s claims, when read
in light of the specification, are limited to a method for making
a transparent, nonporous metal oxide glass film by vitrifying a
reaction product at 200ºC or below (answer, pages 3-4). It
reasonably appears that “metal oxide film” in the appellant’s
claims and “metal oxide glass film” in the appellant’s
specification have the same meaning. Each term refers to the
film formed by the appellant’s method. Also, “maintaining ... at
a temperature” reasonably appears to be the same as “vitrifying
... at a temperature”, both meaning holding the reaction product
at a particular temperature to produce the metal oxide film.
