          Appeal No. 94-4400                                                          
          Application 07/771,063                                                      

          first master node A from the information sent along the sequence            
          of links numbered 201, 202, 205, 208 and 209.  Although the                 
          information received on link 209 contains information about first           
          master link A, the information is sent without any interrogation            
          by the other control nodes.  We see a basic difference between a            
          node sending information about its condition at all times and a             
          node being specifically interrogated by a different specific node           
          to report its status as a primary or alternate control node.                
          As an analogous example of this point, suppose that                         
          person A communicates information to person B, and person B                 
          passes this information on to person C.  Although person C                  

          becomes aware of the information that person A told person B,               
          person C never interrogated person A to get this information.               
          The information was derived by a totally separate channel.                  
          Likewise in the applied prior art, information contained on any             
          one link may contain information that was present on other links            
          but such information was not obtained by an interrogation of                
          links not directly connected.                                               
          Although this distinction may seem trivial to some, it                      
          forms the crux of appellants’ arguments regarding the                       
          patentability of claim 10.  We are not willing to interpret claim
