timing clock signal and then transmits data to the transponder
utilizing the extracted bit timing signal, thereby avoiding the
need to include a bit timing signal in its transmission.
After reviewing the Carroll reference in light of the
arguments of record, we find ourselves in general agreement with
the Examiner’s position as stated in the Answer. As asserted by
the Examiner (Answer, pages 14 and 15), to whatever extent
Appellants are correct in their characterization of Carroll as
originating the generation of a bit timing clock signal at the
transponder, no such requirement is set forth in claim 70 which
merely requires the embedding of a bit timing clock signal in an
alternating magnetic field generated by the reader. We agree with
the Examiner that the alternating magnetic field generated from the
reader in Carroll and received at element 58 in Carroll’s Figure 3
transponder, the output of which is a clock signal input to timing
control 60, has embedded therein a bit timing clock signal as
claimed, regardless of the fact that such bit timing clock signal
may have ultimately originated in the transponder.
The Examiner makes a similar rejection with respect to
independent claim 71 which differs in one respect from claim 70 by
reciting the generation of a bit-timing clock signal. We again
find ourselves in agreement with the Examiner (Answer, page 15)
