Appeal No. 2002-2063
Application No. 09/635,093
Addressing Claim 12 more specifically, it requires the two-
component binder system to consist essentially of: (a) a phenolic
resin component which consists essentially of (i) a phenolic resin
exhibiting free phenolic and free alcoholic OH groups, and (ii) a
solvent for the phenolic resin; and (b) a polyisocyanate component
consisting essentially of (i) a polyisocyanate capable of reacting
with the phenolic resin component to form a resin, and (ii) a
solvent which comprises a fatty acid methyl ester which is a
methyl monoester of one or more fatty acids with a carbon chain of
12 or more carbon atoms.1
The Furness Reference
Our review of Furness reveals that it discloses a phenolic
resin component. Giving the claim terms their plain meaning, a
phenolic resin is a synthetic thermosetting resin obtained by the
condensation of phenol or substituted phenol with aldehydes.2 In
the instant specification, page 6, example 1, a phenolic resin
precondensate is prepared by reacting phenol with
paraformaldehyde.
We find that Furness suggests a phenolic condensation between
a phenol and an aldehyde including paraformaldehyde (column 2,
lines 44-47; column 3, line 65 - column 4, line 1), followed by a
1 Claim 12 also recites that there is more fatty acid methyl ester than high boiling aromatic
hydrocarbon. However, we note that no high-boiling aromatic hydrocarbon is required by the claim.
