polymeric derivatives. See page 1174, column 2. Moreover, to
solve the problem of the cracking of gel films, it is
desirable to add ethylene glycol to the solution to introduce
organic chains in the inorganic network of the gel. See page
1176, column 1. The claimed “polyethylene glycol” is embraced
by the term “glycol” used in the Yi reference, see, e.g., Yi,
page 1175, Fig. 2(B), and is expected to behave in the same or
similar manner as ethylene glycol due to having the same
dihydroxy functional groups at the end of an alkyl chain, see
Yi, page 1174, column 1, together with page 1175, Fig. 2(B).
The solution is deposited on a substrate prior to drying. See
page 1174, column 1 and page 1176, column 3. Although the Yi
reference teaches using an alcohol as indicated supra, it does
not mention employing an amine alcohol.
To remedy this deficiency, the examiner relies on
the Kobayashi disclosure. Kobayashi discloses a process for
producing a superconductor of an oxide system, such as a
Y-Ba-Cu-O system using a sol-gel method. See column 1, lines
7-8, column 2, line 21, and column 4, line 52 to column 5,
line 2. One of the sol-gel methods disclosed involves
initially dissolving metal alkoxides, which may be dispersed
