releasable pressure sensitive adhesive compositions. Compare
the disclosures of Blizzard at column 8, lines 6 through 22.
Accordingly, we cannot sustain the examiner's stated rejection of
the appealed claims based on Blizzard in view of Miller and
Onohara.
The examiner's alternatively stated obviousness rejection of
the appealed claims based on Huddleston in view of Blizzard is
similarly deficient. As appellants point out in their brief,
Huddleston does disclose a pressure sensitive adhesive
composition which contains a block copolymer which has been
crosslinked. However, Huddleston's block copolymer is
crosslinked with sulfur, not a organohydrogenpolysiloxane
crosslinking agent. Moreover, based on the applications of
Huddleston's adhesive, appellants persuasively argue that
Huddleston's pressure sensitive adhesive composition is extremely
strong and would not likely be suitable for use in a releasable
pressure sensitive adhesive application as required by the claims
on appeal herein. Accordingly, we cannot sustain the examiner's
obviousness rejection based principally on Huddleston.
Accordingly, the decision of the examiner is reversed.
