suggested employing Ayerst's technique of channel identification in Dent's radio
communication system.
C. RESPONSIVENESS OF BROADCAST ON SECOND CHANNEL
The examiner finds that in Dent "[a] determination is made if the user terminal is
disadvantaged, and responsive to determining that the user terminal is disadvantaged,
the message is then broadcast from the base station to the user terminal on a second
forward-only radiotelephone channel. See . . . col. 2, lines 15-39, and col. 3, lines 41-
59." (Final Rejection at 2.) The appellants argue that in Ayerst "[t]he long message is
not transmitted on the second channel in response to a determination that the user
terminal is disadvantaged. . . ." (Appeal Br. at 9.)
1. Claim Construction
Claim 1 recites in pertinent part the following limitations: "responsive to
determining that the user terminal is disadvantaged, broadcasting the message from
the base station to the user terminal on a second forward-only radiotelephone channel,
wherein the second forward-only radiotelephone channel is identified with the indication
of a pending message via the first forward-only radiotelephone channel." Giving the
representative claim its broadest, reasonable construction, the limitations require
broadcasting on a second channel if a user terminal is disadvantaged.
