Appeal No. 96-1386
Application 08/030,937
dated May 3, 1995. Claim 12 was allowed in the Examiner’s Answer
(Paper no. 20) dated September 21, 1995. Therefore, claims 1
through 11 and 17 through 19 are properly before us for our
consideration.
The invention relates to land mobile dispatch radio commu-
nication systems. In particular, Appellants disclose on pages 1
and 2 of the specification that unlike radio telephony systems,
where a user establishes contact with another party by inputting
a unique ID code, a telephone number, dispatch radios are pre-
programmed to automatically identify their transmissions as being
intended for reception by members of a particular pre-identified
fleet. The user need only actuate a push-to-talk (PTT) switch on
the radio and begin speaking. Appellants further disclose on
pages 2 and 3 of the specification that video transmission
systems using land mobile dispatch radio units are known.
However, Appellants point out that as of the date of the
filing of the application, a land mobile dispatch radio used
as a video modem is dedicated to this service and precludes the
radio's primary function of providing voice communications.
Appellants disclose that the problem that they solved is
integrating total communications capabilities including audio,
