Appeal No. 95-2799
Application No. 07/799,806
a. a transparent glass substrate;
b. on a surface of said glass substrate a stabilizing
layer selected from the group consisting of silicon,
titanium, zirconium, tantalum, chromium, niobium, silicon
alloys, nickel-chromium alloys and aluminum nitride;
c. a metal compound film with metallic properties
selected from the group consisting of metal borides,
metal nitrides, metal carbides and metal oxynitrides; and
d. a protective layer which prevents oxidation of the
metal compound film upon heating selected from the group
consisting of the nitrides and oxynitrides of silicon and
silicon alloys.
The examiner relies upon the following references:

Appellants' claimed invention is directed to a metallic
coated article comprising a transparent glass substrate, a
stabilizing layer on the glass substrate consisting of, e.g.,
silicon, a film on the stabilizing layer of a metal compound,
e.g., titanium nitride, and a protective layer for the metal
compound film consisting of nitrides and oxynitrides of
silicon and silicon alloys. According to appellants, the
