          Appeal No. 1998-0204                                                        
          Application 08/501,542                                                      


          that claim 1 is unpatentable over Sampietro under 35 U.S.C. §               
          103.  We will therefore sustain the                                         




          Examiner’s rejection of claim 1, and likewise claims 4, 6                   
          through 9, 11 through 13, 15 and 18 through 21 which stand or               
          fall in the same group.                                                     
                    With respect to claim 22, a method rendition of                   
          apparatus claim 1, we will sustain the Examiner’s rejection of              
          this claim for the same reasons enumerated supra.  The claimed              
          method is clearly met by Sampietro, and at least would have                 
          been obvious thereover.                                                     
                    Appellants argue that claims 2 and 3 are patentable               
          over Sampietro because they require the bucking field to be                 
          active “for a time of about 0.10 second”, and this limitation               
          is not necessarily obtained by routine experimentation and                  
          optimization.  (Brief-page 23.)                                             
                    The Examiner maintains that mere experimentation                  
          would determine this time period and cites Sampietro, column                
          2, lines 56-63 (final rejection), wherein it states “by                     


                                          11
