have found it obvious to modify Furukawa’s procedure by
ensuring that a small grain size was produced because same
would have been anticipated to have a higher dielectric
constant” (answer, page 5).
We disagree with the examiner’s position since Furukawa
does not teach or suggest a method of forming a thin film on a
substrate having an average grain size as herein claimed.
Rather, Furukawa (pages 5 and 6) teaches a method for forming
a mixed sintered body wherein a first component mainly
comprising barium titanate is combined with a second
perovskite component containing lead. A binder and solvent
may be used in mixing the components into a slurry and then
the slurry is formed into a thick sheet (for example, 30
micron thickness), which sheet is subsequently sintered
(Furukawa, page 6). The examiner has not fairly explained how
the method of Furukawa reasonably corresponds to appellants’
method such that one of ordinary skill in the art would have
been led to the here claimed subject matter by the teachings
of Furukawa.
Moreover, the examiner’s opinion (answer, page 6) that
appellants do not challenge the examiner’s viewpoints
