not teach or suggest making the feedback connection depend on
'to turn on the FET during a switching transition near the
knee of the transfer curve having two parallel paths.'" See
page 8, lines 2-6 of the brief.
On page 6, lines 15-17 of the answer, the Examiner argues
that Shimizu teaches that "the chain of amplifying circuit is
seen as elements 6-8 and under broadest reasonable
interpretation, it is clear that the positive feedback
(feedback connected from 8 out to 10G) inherently provides a
hysteresis operation recited therein." Emphasis added.
Further, the Examiner argues that, in light of Koyama, showing
a conventional Schmitt trigger that also has the transition
having parallel paths at one knee joining a constant part of
the curve, "[i]t is clear that the applied reference Shimizu
with [sic] has the conventional Schmidt [sic, Schmitt] trigger
response." See page 6, lines 17-20 and page 7, lines 2 and 3
of the answer. Furthermore, the Examiner argues that "it
appears that not only does the Shimizu [reference] show the
same structure, but [it] also performs the same function as
well." See page 7, lines 10-12 of the answer.
