switching output is supplied to the primary winding N1 and MCT
transfers the alternating voltage of the of the switching
frequency generated by the switching output to the secondary
winding Ni through magnetic coupling (col. 6, lines 55-67). As
shown in figure 3, a switching operation by the switching
elements Q1 and Q2 is illustrated in the case of a switching
frequency of 100 kHz. The switching elements Q1 and Q2 repeat
ON/OFF operation alternatingly, and switching currents IC1, IC2
running across each collector and emitter assume the waveforms
shown in figures 3B and 3C, respectively. From the alternative
operation of switching elements Q1 and Q2, and the alternating
voltage generated by the switching output to the secondary
winding, we find that the primary and secondary circuits of
Yasumura conduct at the same time. From all of the above, we
find that the examiner has failed to establish a prima facie case
of anticipation of claim 26 by Yasumura. Accordingly, the
rejection of claim 26, and claims 27-31 dependent therefrom,
under 35 U.S.C. § 102(e) is reversed.
CONCLUSION
To summarize, the decision of the examiner to reject claims
1-31 under 35 U.S.C. § 102(e) as anticipated by Yasumura is
