Appeal 2007-1127
Application 09/800,112
STATEMENT OF CASE
Appellants appeal under 35 U.S.C. § 134 from a final rejection of
claims 22-41. We have jurisdiction under 35 U.S.C. § 6(b).
Appellants invented a method of controlling Internet Protocol (IP)
telephones within a local area network (LAN) implemented or Ethernet PBX
(private branch exchange). (Specification 1:6-8). Specifically, the method
uses a general message template consisting of a Protocol Header and an IP
Message body where the Protocol Header includes an indication of the
Protocol Type, Device Number, and Message Type. (Specification 1:28-30).
Representative independent claim 22 under appeal reads as follows:
22. A method of communication between an IP phone and a
network-implemented PBX comprising:
generating a message to be exchanged between said IP phone
and said PBX;
encapsulating said message with a Protocol Header and an IP
Message body, wherein the Protocol Header includes an
indication of Protocol Type for denoting whether the message is
an IP message or an encapsulated non-IP [sic] message, a
Device Number for denoting by means of MAC (Media Access
Control) an address within said PBX to which said message is
to be transmitted or from which said message is to be received,
and Message Type for identifying the type of message
contained in the IP Message Body; and,
transmitting the encapsulated message.
The Examiner rejected claims 22-41 under 35 U.S.C. § 103(a).
