          Appeal No. 1998-0096                                                        
          Application No. 08/518,182                                                  


          “the conductive metal coating does not need to be a plated                  
          coating, as in Saito      (JP 4-6841). . . ” (Brief, pages 17,              
          20-21 and 23), we find these assertions to be unconvincing.                 
          The transitional open-ended term “comprising” in a claim does               
          not exclude additional, unrecited elements; therefore, whether              
          or not Fujimoto and Saito (JP4-6841) disclose more than what                
          the claimed invention recites is irrelevant under 35 U.S.C. §               
          103(a).                                                                     
               Turning lastly to appellants’ contention that the polymer              
          body recited in claims 7, 11, 15 and 18 “can be an insulating               
          material and does not need to be conductive, as in Saito                    
          (JP4-6841)” (Brief pages 17, 20-21 and 23), we see such a                   
          contention to be unpersuasive.  The term “polymer body”                     
          includes insulating polymer and conductive polymer; therefore,              
          the claimed “polymer body” reads on a “conductive polymer                   
          body.”  Furthermore, the examiner has relied on Saito (JP4-                 
          6841), not for its disclosure of the polymer body material,                 
          but, for its teaching of the equivalents of different polymer               
          body shapes, i.e., columnar, spherical, and cylindrical                     
          shapes.                                                                     
               In view of the foregoing, we determine that the only                   
                                         19
