However, reference to Figures 3 and 4, and column 5,
lines 47-49 indicates that, in Bavaro, the operating point
adjustments and load regulation is a “function of readings
from only the battery current sensor” [emphasis ours]. Thus,
Bavaro specifically teaches that both the battery current and
the load are not employed in operating the pulse width
modulated regulator. We note that column 5, lines 52-53,
recites that “Battery current was chosen for simplicity” which
might leave open the possibility that other current measures
could be employed. However, such a suggestion is still a few
steps away from suggesting that perhaps both battery current
and load current should be sensed. As far as we can tell from
the record, including the examiner’s allegations, the only
suggestion for sensing both the battery current and the load
current comes from appellant’s disclosure alone.
Even in the rationale explaining the rejection, at page 4
of the answer, the examiner states that Bavaro discloses
“...the sensing of the output current delivered to load that
is used as a signal sent to a pulse width modulator to control
the switching power converter...” However, the examiner does
