            Appeal No. 2002-2115                                                                              
            Application No. 09/000,709                                                                        


                   In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden           
            of presenting a prima facie case of obviousness.  See In re Rijckaert, 9 F.3d 1531,               
            1532, 28 USPQ2d 1955, 1956 (Fed. Cir. 1993).  A prima facie case of obviousness is                
            established by presenting evidence that the reference teachings would appear to be                
            sufficient for one of ordinary skill in the relevant art having the references before him to      
            make the proposed combination or other modification.  See In re Lintner, 458 F.2d                 
            1013, 1016, 173 USPQ 560, 562 (CCPA 1972).  Furthermore, the conclusion that the                  
            claimed subject matter is prima facie obvious must be supported by evidence, as                   
            shown by  some objective teaching in the prior art or by knowledge generally available            
            to one of ordinary skill in the art that would have led that individual to combine the            
            relevant  teachings of the references to arrive at the claimed invention.  See In re Fine,        
            837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988).  Rejections based on     §             
            103 must rest on a factual basis with these facts being interpreted without hindsight             
            reconstruction of the invention from the prior art.  The examiner may not, because of             
            doubt that the invention is patentable, resort to speculation, unfounded assumption or            
            hindsight reconstruction to supply deficiencies in the factual basis for the rejection.  See      
            In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177 (CCPA 1967), cert.                           
            denied, 389 U.S. 1057 (1968).  Our reviewing court has repeatedly cautioned against               




                                                      4
