as proposed by the examiner. Since White does not include an
inductance between the current sense signal and the pulse
width modulator, White has no difficulty in constructing an
inductance element. Therefore, there would be no need to
substitute an active filter with a feedback technique.
Accordingly, we find no reason to combine Kusano with White.
Consequently, Kusano fails to cure the deficiencies of White
regarding claims 1 and 6. Since claims 2 and 5 depend from
claim 1, and therefore include the limitation of claim 1 found
lacking from White, we cannot sustain the rejection of claims
2 and 5. Further, claims 13, 16, and 17 require that the slew
rate of the modified sense signal be limited to a
predetermined maximum when it otherwise would exceed the
maximum. Thus, claims 13, 16, and 17 include a limitation
similar to the one of claim 6 found lacking from White, and,
therefore, are not met by White for the same reasons as
discussed above regarding claim 6. Hence, we cannot sustain
the rejection of claims 13, 16, and 17.
Regarding claims 8, 11, and 12, the examiner combines
Sasaki with White stating (Answer, page 6) that it would have
been obvious "to replace the RC slew rate limiting circuit of
