          Appeal No. 1997-0524                                                        
          Application No. 08/495,699                                                  


               In summary, we are left to speculate why one of ordinary               
          skill would have found it obvious to modify the applied prior               
          art to make the combination suggested by the Examiner.  The                 
          only reason we can discern is improper hindsight                            
          reconstruction of Appellants’ claimed invention.  In order for              
          us to sustain the Examiner’s rejection under 35 U.S.C. § 103,               
          we would need to resort to speculation or unfounded                         
          assumptions or rationales to supply deficiencies in the                     
          factual basis of the rejection before us.  In re Warner, 379                
          F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied,               
          389 U.S. 1057 (1968), rehearing denied, 390 U.S. 1000 (1968).               
          Since we are of the view that the prior art applied by the                  
          Examiner does not support the rejection, we do not sustain the              
          rejection of independent claim 1, nor of dependent claims 2-6               
          and 9.  Therefore, the Examiner’s decision rejecting claims 1-              
          6 and 9 under 35 U.S.C. § 103 is reversed.                                  


                                   REVERSED

                                          9
