Appeal No. 97-0984
Application 08/546,345
this contention (note footnote 2 above). The examiner then
notes that even though Crafts does not teach anything about
power conservation, the artisan would recognize that the
Crafts structure “can be” used in the Shay or Mahabadi power-
on reset circuit [id., page 4].
Appellant first argues that there is no suggestion in
any of Mahabadi, Shay or Crafts to modify the inverter
circuits disclosed in Mahabadi or Shay to conserve power in
the operation of their inverters. We note that the only
cited references dealing with the question of conserving
power in an inverter are the unapplied Masuoka and Ludwig
references. As noted above, we will not consider these
references since they were not indicated in the statement of
the rejection. Therefore, the motivation to modify the Shay
or Mahabadi inverter to be like the Crafts inverter must come
from one of these three references or other knowledge
generally available to the artisan.
The purpose of the inverter in Crafts is to limit the
output current of a driver independent of the supply voltage,
load capacitance, temperature and other processing variables
