Appeal No. 95-0005
Application 08/141,412
not have reasonably suggested a single inductive coupling for
communicating between the interrogator and the transponder.
In that regard, we have found that White (column 7, lines 23-
28) discloses that inductive coupling may be used to send
information back and forth between an interrogator and a
memory system which stores utility measurement data. But the
examiner did not rely on White for that purpose, and White
does not disclose that the interrogator sends a clock signal
to a transponder and that the transponder modulates the
measurement data over the clock signal for transmission back
to the interrogator through the same single inductive
coupling. The "single inductive coupling" claimed by the
appellant is more specific than the general inductive coupling
teaching of White.
In Lapsley, there is a group of signal input lines 35 and
a group of signal output lines 31. Depending on the state of
the measurement index wheels, different electrical contacts
are made in the signal path and thus different output lines
will carry a corresponding output. It is not seen how such a
system includes a transponder which first "determines" the
