Appeal No. 1998-3144
Application No. 08/436,688
that using less than 40 parts of latex per 100 parts of
prepolymer results in the resiliency of the foam being
"undesirably high" (see column 2,
lines 5-8). Arnason, on the other hand, is directed to making
a
squeezable toy with dimensional memory from polyurethane foam,
and the reference provides no teaching or suggestion that
utilizing a rubber latex in the claimed amounts would render
the polyurethane foam suitable for contacting wounds.
Hence, although the examiner is correct in stating that
the applied prior art teaches that using less than the
disclosed rubber results in the foam having a higher
resiliency, the examiner has not established why one of
ordinary skill in the
art would have had a practical reason to do so.
Based on the foregoing, the examiner's decision rejecting
the appealed claims is reversed.
REVERSED
