Appeal No. 95-0808
Application 08/048,866
Rejection under 35 U.S.C. § 103 over
Fujioka in view of Schroeder
In Example 4 of Fujioka, a colorless, transparent
overcoat composition is formed by mixing (-glycidoxypropyl
trimethoxy-silane and tetraethoxysilane, i.e.,
tetraethylorthosilicate, to effect hydrolysis. The (-
glycidoxypropyl trimethoxysilane falls within the scope of the
alkoxide recited in appellants’ claim 1.
Fujioka does not disclose inclusion of cerium oxide in his
overcoat compositions, but teaches that the compositions may
contain an ultraviolet absorbent (col. 8, lines 21-34).
Schroeder teaches that cerium oxide is one of four
disclosed metal oxides which are depositable from organic
solutions and which exhibit an especially steep rise of
absorption in the near ultraviolet range, and that layers
which contain these metal oxides serve as efficient cutoff
filters for shorter-wave ultraviolet radiation (page 137).
In our opinion, the teaching by Schroeder that cerium
oxide is an effective ultraviolet ray absorbent in layers
would have fairly suggested, to one of ordinary skill in the
art, use of
