Appeal No. 95-0808
Application 08/048,866
appellants regard as the invention.
OPINION
The application before us is a continuation-in-part of
Application 07/300,663 which previously was before the board
(Appeal No. 92-2464). In that case, the only independent
claim read as follows:
1. An optically transparent coating composition
which reduces transmission of ultraviolet
radiation consisting essentially
of:
a. an alkoxide of the general formula R M(OR’)
x z-x
wherein R is an organic radical selected
from the group consisting of alkyl,
vinyl, phenyl, methoxyethyl, (-glycidoxypropyl
and (-methacryloxypropyl, M is selected from
the group consisting of silicon, aluminum,
titanium, zirconium and mixtures thereof,
R’ is an alkyl radical which forms a
hydrolyzable alkoxide, z is the valence of M
and x is less than z and may be zero, partially
hydrolyzed such that a portion of OR’ is
replaced with hydroxyl groups; and
b. the reaction product of tetraethylorthosilicate
and cerium oxide.
The board affirmed rejections of all of the claims under 35
-4-4
