          Appeal No. 1998-1426                                                        
          Application No. 08/315,350                                                  


          one skilled in the art who is presented only with the                       
          references, and who is normally guided by the then-accepted                 
          wisdom in the art."  Id.                                                    
               Since we have determined that the examiner’s conclusion                
          of obviousness is based on a hindsight reconstruction using                 
          appellants' own disclosure as a blueprint to arrive at the                  
          claimed subject matter, it follows that we will not sustain                 
          the examiner's rejection of independent claims 1, 12 and 17,                
          or of claims 2, 10, 13, 18 and 20, dependent thereon, under 35              
          U.S.C.                                                                      
          § 103(a) as being unpatentable over Durkop in view of Bliss.                
               We have additionally reviewed the patents to Lindquist,                
          Gelin and De Benedittis applied by the examiner against                     
          dependent claims 3, 4, 5 and 30, however, we find nothing in                
          these references which provides for that which we have                      
          indicated above to be lacking in the basic combination of                   
          Durkop and Bliss.                                                           
          Accordingly, the examiner's rejections of dependent claims 3,               
          4, 5 and 30 under 35 U.S.C. § 103(a) will likewise not be                   
          sustained.                                                                  
               We next turn to the examiner’s rejection of independent                
                                          9
