employing the type of elastomeric block copolymers as the
binder for their photocurable compositions. See Answer, pages
12-13 and 19-20. We also agree with the examiner’s finding
that both Hsieh and Wright teach elastomeric block copolymers
which meet such criteria. See Answer, pages 13 and 20.
Further, we agree with the examiner’s finding that both Hsieh
and Wright teach that their elastomeric block copolymers
impart desired and advantageous properties, including ozone
resistant properties. See, e.g., Answer, pages 6 and 7.
Given these advantages and the compatibility of the
elastomeric block copolymers described in Hsieh and Wright in
the photocurable compositions of DuPont or Garmong, we agree
with the examiner that it would have been prima facie obvious
to employ
Hsieh’s or Wright’s elastomeric block copolymers as the binder
of the photocurable compositions of the type described in
DuPont and Garmong. Appellant’s reliance on Morton does not
negate the teachings of DuPont and Garmong, which indicate
