Appeal No. 1998-3106
Application 08/679,603
appellants’ claim 1): (A) a vinyl-containing
polyorganosiloxane having an average of about two silicon-
bonded vinyl radicals per molecule (col. 2, lines 7-9; this
component corresponds to the appellants’ component (A) which
is curable by a hydrosilylation reaction (specification, page
4)); (B) an optional inhibitor for the hydrosilylation
reaction (col. 3, lines 27-39); (C) an organosilicon compound
having an average of at least 3 silicon-bonded hydrogen atoms
per organosilicon compound molecule and which may be a
homopolymer, copolymer or mixture thereof (col. 2, lines 15-
18; col. 5, lines 12-47); and (D) an adhesion additive
(col. 3, lines 1-5) composed of: (D)(a) a silane having at
least one epoxy functionality and at least one alkoxy
functionality (col. 2, lines 39-41; col. 6, lines 44-49), and
(D)(c) a polysiloxane having hydroxyl siloxane units as end
groups and preferably having methylvinylsiloxane units and
dimethylsiloxane units as the other siloxane units (col. 2,
lines 27-39; col. 6, lines 33-38). Schulz also discloses a
platinum catalyst (col. 2, lines 26-27). Schulz does not
