Application 10/422,661
defeating searching for said network signal [emphasis added].” (Claim 1).
After carefully examining the record before us, we find Appellant
acknowledges in the Brief that Pombo’s “no control activity” process will
result in a state of lower power consumption and will defeat searching for
the calculated time interval, as follows:
There is no mention of entering “sleep mode” during this
period, only of delaying the next search until the next search
time, which would save some battery power, but not as much as
going into “sleep mode.”
(App. Br. 5, ¶1).
In particular, we note that a particular degree or amount of battery
power saving is not claimed. Thus, we find the portion of Pombo, at column
11, lines 27-62, discloses calculating a nap termination condition upon each
detection of network signal loss (i.e., a determination is made that no control
channel was detected, col. 11, l. 29), and entering a nap mode (i.e., a battery
saving mode) until the nap termination condition is met, as required by the
language of representative claim 1. Thus, while we agree with Appellant
that Pombo’s sleep mode, as shown in block 614 of Fig. 6, is not entered
into upon each detection of network signal loss, we nevertheless find that
Pombo also discloses a “no control activity” process (col. 11, l. 41) which
results in a period of reduced power consumption and suspended searching,
that is entered upon each detection of network signal loss (See Pombo, col.
11, ll. 41-45).
Regarding Appellant’s fourth argument (i.e., that Pombo does not
disclose the length of time of finding a signal and the length of time of
