                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).
