Appellants argue that there is no motivation for making
the modification proposed by the examiner, and the combination
fails to meet the claimed feature of monitoring CCS signaling and
deriving presence and availability information from the monitored
CCS signaling [brief, pages 10-12].
The examiner responds that the CCS signaling network of
Lane clearly shows displaying status information of a network.
The examiner reiterates that it would have been obvious to the
artisan to use the CCS signaling network of Lane to monitor the
status of devices in Tang [answer, page 12].
We will sustain the examiner’s rejection of claim 23 for
essentially the reasons argued by the examiner in the answer. As
