          Appeal No. 2002-0042                                                        
          Application 08/211,971                                                      



               does not provide any explanations as to the manner in                  
               which the user input windows A30, B30 could be                         
               considered to form part of a common image that is                      
               observable by each of the users.                                       
               In response to the examiner's position in the answer                   
          relating to the feature of mutually exclusive display areas and             
          the examiner's position therein that Nakayama can be interpreted            
          to disclose display areas that are mutually exclusive, we agree             
          with the following from pages 2 and 3 of the reply brief:                   
               However, Appellants do not dispute the fact that the                   
               Nakayama et al patent can be interpreted to disclose                   
               mutually exclusive display areas.  In fact, in their                   
               Brief, they explicitly acknowledged this fact.  The                    
               second full paragraph on page 6 of the Brief states                    
               "The patent [Nakayama et al] also discloses mutually                   
               exclusive windows that are associated with the                         
               respective users' input devices, e.g., A30 and B30."                   
               The Brief goes on to point out, however, that these                    
               windows do not form part of a common image that is                     
               simultaneously observable by each of the users, as                     
               recited in the claims.  The Answer fails to address                    
               this aspect of the invention that was identified by                    
               appellants as being one of its distinguishing features.                
               Hence, the examiner still has not shown where the                      
               reference disclose every feature of the claimed                        
               invention, either explicitly or inherently, as required                
               for a proper rejection of anticipation under 35 U.S.C.                 
               § 102.  A showing that the reference discloses some of
