Appeal No. 1998-1133
Application 08/382,296
(col. 4, lines 18-23; col. 4, line 75 - col. 5, line 3).
For the above reasons, the applied prior art would have
fairly suggested, to one of ordinary skill in the art, the
method recited in the appellants’ claim 22.
The appellants argue that Dunne and Säufferer do not
disclose bypassing any of the exhaust gases around an upstream
unit at start-up (brief, page 10). The appellants’ claim 22,
however, does not require such bypassing at start-up. What
the claim requires is that catalyst within an igniter is
permitted to increase the temperature of exhaust gases passing
through the igniter and that exhaust gases are passed through
a catalyst bed within a catalytic converter after a first
portion of the exhaust gases has passed through the igniter
and the temperature of the exhaust gases has been raised to a
temperature to ignite the catalyst within catalyst bed of the
catalytic converter. As discussed above, both Dunne and
Säufferer meet these requirements.
