          Appeal No. 1997-2455                                                        
          Application 08/318,235                                                      

          power storage portion, and when the power from the transducer               
          is insufficient the stored power is supplied to the tag.                    
               Turning to the rejection under 35 U.S.C. § 103.  On page               
          4 of the answer, the Examiner states that Beigel does not                   
          teach the claimed two-stage power developer.  We agree.                     
          Beigel teaches that the power to the tag is supplied by an                  
          AC/DC converter connected to the transducer.  See column 5,                 
          lines 19 through 23.  We fail to find that Beigel teaches                   
          storage of some of the power for use when the power supplied                
          from the transducer is insufficient.  We find that Schuermann               
          teaches a transponder tag which receives a radio frequency                  
          (RF) interrogation signal from a reader through a resonant                  
          circuit.  The energy coupled through this resonant circuit is               
          stored in a capacitor, item 136.  See column 4, lines 48                    
          through 52, and column 4, line 65 through column 5, line 1.                 
          After the voltage is high enough and the RF signal has ceased,              
          the stored energy is used to power the circuits of the tag.                 
          See column 5, lines 18 through 36.  Switch 156 supplies power               
          to the circuits from capacitor 136.  We find that Schuermann                
          does not provide power to the tag’s components directly from                
          the transducer.                                                             

                                         19
