Application 10/085,138
obvious to the artisan to delay voltage sensing circuits as
taught by Holmquest during power-up conditions for reasons taught
by Tran.
With respect to separately argued claim 17, in addition
to the arguments we considered above, appellant argues that
Holmquest does not teach sensing circuits being operable to
detect the various fault conditions recited in claim 17.
Appellant argues that Holmquest discloses only a single phase
sensor, but as noted above, Holmquest clearly discloses three
phase sensors 12-14 [brief, pages 8-9]. The examiner responds
that Holmquest discloses a voltage sensor for each phase. The
examiner notes that an opening of any phase in Holmquest will
result in an undervoltage condition detectable by the Holmquest
circuit [answer, page 13]. Appellant responds that Holmquest can
only detect a problem with one of the three phases and cannot
distinguish problems between the phases [reply brief, pages 6-7].
We will sustain the examiner’s rejection of
representative claim 17 for essentially the reasons argued by the
examiner in the answer. Claim 17 does not require that the
circuit be capable of detecting problems between phases. Claim
17 only recites that the fault condition is selected from a group
of possible fault conditions. The examiner is correct that open
