increasing or decreasing resulting in heating or cooling. The
terms heating and cooling imply that a prediction of the future
temperature conditions is being contemplated.
With respect to item 9 (claim 22, (rehearing request at page
23), Appellant objects to our statement in the decision at page 15,
namely, “the clock rate ‘HAS TO BE’ regulated in such a way that
the temperature does not exceed the selected reference level and in
doing so they would have to control the length of the OFF state for
the power to the CPU”. For clarification, we add here that Kenny
as pointed out, supra, teaches the concept of having the power off
in case of a heat build up in an integrated circuit (column 1,
lines 51-64). Therefore, an artisan would have found it obvious to
control the off state condition of the clock pulses going to the
CPU in order to avoid the build up of heat in the chip (CPU), and
hence prevent the rising of the temperature of CPU beyond a
selected reference temperature level.
Concerning item 10 (claim 23, rehearing request at page 24),
we find that Appellant has recited no particular structure or
specific method for the accomplishment of the recited optimized
efficiency level of the CPU in claim 23. We are of the view that
an artisan, knowing from the teachings of the combination of Smith,
