Appeal No. 1998-3342 Page 9
Application No. 08/540,943
Appellant can find no teaching in Sasaki of overlapping
reception ranges.” (Appeal Br. at 9.) Claims 2 and 5 specify
in pertinent part the following limitations: "adjusting
sensitivity of the receiver by attenuating signals received by
the antenna, wherein the reception ranges for the plurality of
receivers are adjusted to overlap to permit continuous
tracking of the plurality of transmitters within the reception
ranges.” Similarly, claims 3 and 6 specify in pertinent part
the following limitations: “an attenuator, inserted between a
receiver of the plurality of receivers and its associated
antenna for adjusting the reception range which the antenna
receives, wherein the reception range of each of the plurality
of receivers is adjustable for controlling overlap of
reception ranges.” Accordingly, claims 2, 3, 5, and 6 require
adjusting reception ranges of antennae to control overlap of
reception ranges of respective associated receivers.
The examiner fails to show a teaching or suggestion of
the limitations in the prior art of record. As explained
regarding the first group of claims, Sasaki’s variable
attenuators are adjusted to achieve a linear input-output
