          Appeal No. 2000-2294                                                        
          Application No. 08/511,425                                                  


               We further note that even assuming, arguendo, that the                 
          recited limitations of the appealed claims are found in                     
          various ones of the prior art references, the Examiner’s                    
          rejection is totally lacking in any rationale as to how and                 
          why the skilled artisan would modify the prior art to arrive                
          at the claimed invention.  We are left to speculate why one of              
          ordinary skill would have found it obvious to modify any of                 
          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.                  
          Accordingly, because the Examiner has not established a prima               
          facie case of obviousness since all of the limitations of the               
          appealed claims are not taught or suggested by the applied                  
          prior art, the Examiner’s 35 U.S.C.     § 103 rejection is not              
          sustained.                                                                  











                                          16
