Appeal No. 96-1582
Application No. 08/292,928
more than 10% total harmonic distortion. We note that Stupp
does suggest that it is desirable to have a low harmonic
distortion, indicating at column 7, lines 43-53 that “above
40% for the third harmonic” would be an “unacceptable level of
line current harmonic contents.” However, we find no
suggestion therein of the more limited and specifically
claimed “not more than 10% total harmonic distortion.”
Thus, we will not sustain the rejection of claims 1
through 7 under 35 U.S.C. § 103.
Turning now to independent claim 16, appellant argues
that the claim requires the instantaneous absolute magnitude
of the first DC voltage be “substantially equal” to that of
the AC power line voltage.
The examiner relies on Figure 2A of Stupp and contends
that this is a
voltage waveform of the current produced at the
output terminals of rectifier 10, which magnitude,
the examiner maintains, would be “substantially
equal” to that of the AC power line voltage’s in the
absense [sic] of a transformer or other circuitry
that would effect a substantial difference in
voltage magnitude of the two voltages [emphasis in
the original-answer-page 3].
