          Appeal No. 95-3592                                                          
          Application 08/109,203                                                      



          claimed invention."  RCA Corp. v. Applied Digital Data Sys.,                
          Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir.),                   
          cert.                                                                       


          dismissed, 468 U.S. 1228 (1984), citing Kalman v. Kimberly-                 
          Clark Corp., 713 F.2d 760, 772, 218 USPQ 781, 789 (Fed. Cir.                
          1983), cert. denied, 465 U.S. 1026 (1984).                                  
                    Appellants argue in the brief, reply brief and                    
          supplemental reply brief that Shirato does not teach a                      
          resistive means having a resistance responsive to the voltage.              
          We note that Appellants' claim 1 recites "a resistive means                 
          being electrically connected between said first heavily doped               
          region and said second heavily doped region having a                        
          resistance responsive to the voltage between said first                     
          heavily doped region and said second heavily doped region."                 
                    The Examiner argues that Shirato teaches Appellants'              
          claimed resistive means.  The Examiner shows that Shirato's                 
          element 26 of a cross sectional view of a protection device in              
          Figure 1(a) is a resistive means being electrically connected
