Appeal No. 2002-0701
Application 09/201,269
referring to all initiators that contain a t-butyl group. The
examiner has not established that Oshima discloses equivalence
and interchangeability of all such initiators and t-butyl peroxy
isopropyl carbonate. Moreover, the examiner has not established
that any equivalence and interchangeability of these initiators
for Oshima’s use, i.e., making high impact strength molded
articles, would apply to Houser’s or Puschak’s polymerizations
for making printing inks.
The examiner argues that in view of Oshima’s teaching that
using too much initiator compromises the mechanical and thermal
properties of the composition (col. 7, lines 14-20), one of
ordinary skill in the art would have used Oshima’s initiators in
Houser’s and Puschak’s polymerizations to control the mechanical
and thermal properties of the polymer (answer, pages 9-10). The
examiner, however, has not established that the mere teaching
that too much initiator adversely affects the mechanical and
thermal properties of Oshima’s polymer for making a high
mechanical strength molded article would have led one of ordinary
skill in the art to use Oshima’s initiators in Houser’s and
Puschak’s polymerizations for making printing inks.
