Appeal No. 1998-1181
Application No. 08/442,883
monitoring primary and secondary carrier signals in search of
a SID matching a SID among the defined plurality of home SIDs.
As regards to claims 50 and 57 Appellants assert that 21
Blair does not teach a plurality of home SIDs and a plurality
of preferred SIDs in a method of carrier selection.
The Examiner refers to the abstract of Blair and again22
asserts that it teaches the limitation of defining multiple
home SIDs. In the rejection of these claims the Examiner 23
posits that by programming with one or more “good” SIDs
(preferred SIDs), the telephone unit can select a frequency
corresponding to a preferred system which has the “good” SID
when the service of the home system is not available. The
Examiner then finds that it would have been obvious to one of
ordinary skill in the art at the time the invention was made
to modify Blair's cellular system with a selecting step
utilizing a preferred SID (or a “good” SID) in order to obtain
more choices in selecting the preferred system in the event
that the service of the home system is not available.
