          Appeal No. 2001-1451                                                        
          Application No. 09/166,656                                                  


          shortcomings of Filippazzi, we cannot sustain the rejection of              
          claims 1 and 2.                                                             
               For claims 3 through 17 and 19 through 23, the examiner                
          (Answer, pages 5-6) adds Chatterjee to the basic combination of             
          Filippazzi and AAPA to show source and drain regions.  The                  
          examiner contends (Answer, page 6) that "Chatterjee explicitly              
          teaches a probe 144 connected to source/drain 98 active regions."           
          The examiner concludes (Answer, page 6) that it would have been             
          obvious to connect the probes of Filippazzi "to active regions of           
          a MOSFET transistor, namely the source/drain regions, in order to           
          test the active regions of a MOSFET transistor."                            
               In rejecting claims under 35 U.S.C. § 103, it is incumbent             
          upon the examiner, in accordance with Graham v. John Deere Co.,             
          383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966), to provide a reason            
          why one having ordinary skill in the pertinent art would have               
          been led to modify the prior art to arrive at the claimed                   
          invention.  Such reason must stem from some teaching, suggestion            
          or implication in the prior art as a whole or knowledge generally           
          available to one having ordinary skill in the art.  Uniroyal,               
          Inc. v. Rudkin-Wiley, 837 F.2d 1044, 1052, 5 USPQ2d 1434, 1438              
          (Fed. Cir. 1988), cert. denied, 488 U.S. 825 (1988).  These                 
          showings by the examiner are an essential part of complying with            
                                          5
