controlling the energy delivered to the turbine response based
upon the desired energy power demand. See Column 13, lines 4
through 18. However, we do not find that Lauw teaches that
the speed of the turbine is responsive to load and ambient
temperature.
Thus, we find that neither Carroll nor Lauw teaches or
suggests that the speed of the turbine is controlled based
upon load demand signal and that the speed of the generator is
responsive to load and ambient temperature. Accordingly, we
will not sustain the rejection of claims 10 through 12 and 18
through 23 under 35 U.S.C. § 103.
We next consider the rejection of claims 13 through 17
and 24 through 33 under 35 U.S.C. § 103 as being unpatentable
over Carroll in view of Lauw and Geary. We find that the
scope of independent claims 13, 16 and 17 includes the
limitation that generator is controlled based upon load
demanded and that the speed of the generator is responsive to
load and ambient temperature. This scope is shown in the
following limitations of claim 13: “controlling an amount of
fuel supplied to the combustor in response to a load demand
signal,” and “means for controlling the rotational speed of
