Appeal No. 96-0613
Application No. 08/226,539
The examiner submits that JPA ‘942 discloses a
composition comprising (A) an epoxy resin, (B) a silicone
resin, and (C) an organopolysiloxane block copolymer (answer,
page 4). The examiner acknowledges that the “organosiloxanes
are not exact,” i.e., the organopolysiloxane block copolymer
of JPA ‘942 is not identical to component (B) in appealed
claim 7. Accordingly, the examiner applies the Griswold
reference for the disclosure of a controlled release agent
comprising a silicone resin where “said copolymer [the
silicone resin] reads on applicants’ claimed epoxy functional
siloxane” (answer, page 5). The examiner concludes that “it
would have been obvious to one skilled in the art to use the
composition as found in the JPA [’942], . . . and to
substitute the epoxy functional siloxanes with the siloxanes
of Griswold, since they are clearly functional equivalent
epoxy-siloxane release agents.” (Id.).
Appellants argue that there is no basis to combine
Griswold with JPA ‘942, as Griswold is concerned with a five-
component pressure-sensitive adhesive while JPA ‘942 is
directed to silicone-epoxy molding compositions for electronic
components (brief, page 5). Appellants argue that there is no
