1 Thus, a person of ordinary skill in the art would have immediately envisaged
2 that Rigby’s two switches have four possible positions (both on, either one on
3 alone, both off), of which two (either one on alone) or three (either one on alone,
4 both off) are possible with the rocker arm over the switches.
5 Garito suggests the desirability and capacity of combining cutting and
6 cauterizing by a surgical instrument by combining multiple frequency signals.
7 That [r.f.] carrier is then pre-amplified in block 48 and inputted to a
8 conventional modulator stage 50. Also input to the modulator stage is
9 a modulating signal 52 derived from a CPU selection signal 54 and a
10 D/A converter 56. The modulations referred to are the different
11 output waveforms used for the known CUT, CUT/COAG, HEMO,
12 and FULGURATE modes. These typically are: CUT-CW (full-wave
13 rectified and filtered) output with maximum average power;
14 CUT/COAG -full-wave rectified but unfiltered, deeply modulated, at
15 37.5 or 75 Hz rate, envelope with approximately 70% average to peak
16 power ratio;….
17 (col. 3, ll. 47-54).
18 Signal modulation is a form of combining signals. One of the results of
19 modulation is that, if the result of a signal modulated by another signal is applied
20 to a point, both of those frequencies are applied to that point.

22 ANALYSIS
23 Claims 1-6, 8-11, 13, 37 and 38 rejected under 35 U.S.C. § 103(a) as obvious over
24 Garito, Ryan, Rigby and Appellants' admission that provision of an insulating
25 choke element and of a supply conductor which has a length of an odd number of
26 quarter wavelengths is prior art.
