memory 25. Thus, Brifman does not send coded signals to a
breaker, and a decoder is not located at the breaker to receive
nonexistent coded signals.
Although Geyer may in fact disclose "that it is
conventional to utilize a data bus for switching device/circuit
breaker data communication, and that such devices may be uniquely
addressed" (Answer, page 6), the applied references still lack
the claimed decoding means associated with a circuit breaker to
receive a coded signal and to send back a response signal.
Brodsky discloses bidirectional control of circuit
breakers, but not in the manner set forth in the claims on
appeal.
Breimesser discloses a return line (column 3, lines 12
through 28), but we agree with appellants' argument (Brief, page
11) that "the outgoing and return lines are the outgoing and
return of current lines for the 'low voltage circuit'" and that
"Breimesser does not teach the use of a decoding means which
decodes its designated coded signal and which returns a response
signal."
We agree with the examiner (Answer, page 7) that Figure
1 of Miller discloses "a system which includes a decoder,
transceiver or the like (56) connected to a data bus or the like
