Appeal No. 1998-0493
Application 08/364,000
communication. (Brief-pages 5 and 6.) Appellant states
“Thus, the channel is maintained, presumably in the hope that
operating voltage level would be restored and communication
resumed. This is contrary to the claimed invention wherein
the base station is signalled to drop the channel, and
communication is forcibly terminated.” (Brief-pages 6 and 7.)
We acknowledge the Examiner’s evidence, and we
believe Appellant agrees, that it is well known to terminate a
conversation and signal the base station to drop the channel
(evidenced by Kerr and Lee). However, we agree with
Appellant. Although Saito terminates conversation upon
detection of a low voltage, it then goes into a “waiting
state”. There is nothing in the record to indicate Saito’s
“waiting state” is the same as terminating a conversation and
relinquishing the channel. Saito’s “waiting state” appears to
be a non relinquishing of the channel. This is indicated by
Saito wherein it states:
Unless the normal voltage level in restored even
after the lapse of three seconds from the voltage
drop, the mobile radiotelephone stays in an
inoperable state. (Emphasis added.)(Column 1, lines
23-26.)
