Additionally, independent claims 17, 19, and 26 each
recite that the frequency of the output voltage is changed
away from the natural resonance frequency of the L-C circuit
to change the magnitude of the output voltage. Appellant
contends (Brief, pages 5 and 6) that neither Perper nor Elms
teaches or suggests any relationship between the AC output
voltage frequency and the natural resonance frequency of the
L-C circuit, and more specifically, changing the AC output
voltage frequency away from the natural resonance frequency of
the L-C circuit. The examiner postulates (Final Rejection,
page 3) that "[i]t is a simple matter of design consideration
for one of ordinary skill in the art to realize that moving
... below or above the resonance frequency of the tuned
circuit will lower the AC output level (keeping in mind the
bell shaped curve with the maximum output at the resonant
frequency)."
Again the examiner has provided no evidence in Perper or
Elms suggesting that the circuitry in the references performs
as recited in the claims, such that the output voltage changes
in response to a change in the frequency of the output voltage
away from the resonant frequency of the L-C circuit. Further,
