          Appeal No. 1998-1288                                                        
          Application No. 08/502,817                                                  

          inductor.  The examiner bases his position on nothing more                  
          than a perceived inherent property of the (gapped) magnetic                 
          core 47 of Zansky.  A prima facie case of obviousness is not                
          established by mere conjecture of the examiner.  The claims                 
          also recite a specific property of the loose coupling which                 
          the examiner has dismissed as routine skill of the artisan.                 
          The obviousness of the specific property recited in                         
          appellant’s claims also cannot be met by the mere conjecture                
          of what the examiner deems to be obvious.  The examiner has                 
          failed to provide us with an evidentiary record which clearly               
          supports the obviousness rejection.                                         
               We also agree with appellant that the examiner has not                 
          supported his position that it would have been obvious for the              
          series-combination of an inductor and a capacitor to be                     
          naturally resonant at a frequency lower than the fundamental                
          frequency of the gas discharge lamp.  Zansky discloses a                    
          ballast circuit operating at a resonant frequency equal to the              
          fundamental frequency.  The examiner has pointed to no                      
          specific portion of Cox, and we have found none, which                      
          suggests that the Zansky ballast circuit would be improved by               
          having the resonant frequency lower than the fundamental
