claim and any intervening claims (Answer, page 2, ¶(3)).
Accordingly, the claims under rejection in this appeal are claims 1
through 26. We have jurisdiction pursuant to 35 U.S.C. § 134.
According to appellants, the invention is directed to
a liquid composition which is polymerizable, by means of radical
polymerization with low shrinkage, into organic glasses,
comprising the product obtained from the transesterification
of a diallylcarbonate (A) with a mixture of one or more linear or
branched aliphatic diols (B), containing from 3 to 10 carbon atoms
in the molecule, with a linear or branched aliphatic polyol (C),
containing from 4 to 20 carbon atoms in the molecule, where the
molar ratio (A)/(B+C) ranges from 2.5/1 to 4/1 and the quantity of
(C) in the mixture (B+C) ranges from 5% by weight to 20% by weight
with respect to the total weight of the mixture (Brief, page 2). A
copy of representative independent claim 1 is attached as an
Appendix to this decision.
The examiner relies upon Renzi et al. (Renzi), U.S. Patent No.
4,970,293, issued Nov. 13, 1990, as evidence to support the sole
rejection on appeal (Answer, page 3, ¶(9)). Claims 1-26 stand
rejected under 35 U.S.C. § 102(b) as “clearly anticipated” by Renzi
(Answer, page 3, with reference to the final rejection of Paper No.
7 for a statement of the rejection). Since we determine that the
