Appeal No. 1997-2628 Page 5
Application No. 08/383,713
The examiner (answer, page 5) further opines that:
[t]he basis for the combination is that Higaki
clearly shows that microwave component can be formed
by using Tl-Ba-Ca-Cu-O compounds as superconductor
materials and heat treatment of the deposited thin
film would enhance thin film uniformity and
characteristics.
The difficulty we have with the examiner’s stated
position stems from the fact that Higaki’s teachings are
directed to a method of forming a single thin film at the
{110} plane of a single crystal of magnesium oxide, not a
process for forming thin films on opposite planar surfaces of
a dielectric substrate in a manner to produce essentially
uniform superconductive characteristics for both films. (See
Higaki at column 2,
lines 66 through column 3, line 9 and the examples).
Moreover, the examiner has not specifically pointed out where
either of the alternative secondary references relied upon by
the examiner teaches or suggests a method, as claimed herein,
for forming such films of substantially uniform
superconductive characteristics on opposite sides of a
dielectric substrate.
