          Appeal No. 2003-2053                                                        
          Application 08/646,500                                                      

               Upon our review of Larson and Shinjo, we fail to find that             
          either reference teaches “stacking the accessories serially                 
          between the application and the conference component” as recited            
          in claim 13 or “linking all automatic accessories serially                  
          between the teleconferencing application and a conference                   
          component” as recited in Appellant’s claim 17.  Therefore, we               
          will not sustain the Examiner’s rejection of claims 13, 14 and 17           
          under 35 U.S.C. § 103.                                                      
               Claims 12, 15 and 18 stand rejected under 35 U.S.C. § 103 as           
          being unpatentable over Larson in view of Leondires.  Appellant             
          argues that neither Larson nor Leondires teaches or suggests                
          determining if a second end point participating in a                        
          teleconference has a capability of the accessory as required by             
          claim 12.  Appellant agrees that Leondires does teach a multi               
          audio-video conferencing system that performs a hardware check to           
          determine if the participant’s system in an audio-video                     
          conference has hardware sufficient to participate in the                    
          conference.  However, the Appellant argues that Leondires does              
          not teach or suggest determining if a second end point                      
          participating in a teleconference has accessories capabilities.             
          See pages 21 and 22 of the brief.  Appellant makes similar                  
          arguments for claim 18 arguing that neither Larson nor Leondires            
                                          14
