          Appeal No. 2005-1576                                                        
          Application No. 09/885,217                                                  


               We further find to be unpersuasive Appellants’ argument                
          (Reply Brief, page 2) that, unlike the claimed invention, the               
          reference signal in Morishita does not have a desired                       
          relationship with the external voltage.  In support of this                 
          contention, Appellants rely on certain portions of Morishita                
          which, in their view, suggest that no reference voltage is                  
          produced until the external voltage exceeds a predetermined                 
          voltage level.                                                              
               It is our opinion, however, that even assuming, arguendo,              
          that Appellants’ characterization of the operation of the                   
          circuitry of Morishita is correct, such circuit operation in fact           
          satisfies the language of claim 223.  In other words, the fact              
          alone that a reference voltage in Morishita may not be produced             
          until an external voltage exceeds a prescribed level establishes,           
          in our view, a desired relationship with such external voltage.             



          Similarly, the reliance on the attaining of a voltage level by              
          the external voltage in Morishita before a reference voltage is             
          produced makes Morishita’s reference voltage dependent on the               
          external voltage as claimed.                                                
               In view of the above discussion, since the Examiner’s prima            
          facie case of anticipation has not been overcome by any                     

                                          7
