          Appeal No. 2000-1314                                       Page 8           
          Application No. 09/109,279                                                  


          portion as set forth in claims 1 to 9, 13 to 17, 19 to 21 and               
          28 to 30.                                                                   


               In our view, the only suggestion for modifying either                  
          Gutentag or Kawanishi in the manner proposed by the examiner                
          to meet the above-noted limitations stems from hindsight                    
          knowledge derived from the appellant's own disclosure.  The                 
          use of such hindsight knowledge to support an obviousness                   
          rejection under                                                             
          35 U.S.C. § 103 is, of course, impermissible.  See, for                     
          example, W. L. Gore and Assocs., Inc. v. Garlock, Inc., 721                 
          F.2d 1540, 1553, 220 USPQ 303, 312-13 (Fed. Cir. 1983), cert.               
          denied, 469 U.S. 851 (1984).  It follows that the decision of               
          the examiner to reject claims 1 to 9, 13 to 17, 19 to 21 and                
          28 to 30 under                                                              
          35 U.S.C. § 103 is reversed.                                                


               It follows from our decision to reverse the examiner's                 
          rejection of claims 1 to 9, 13 to 17, 19 to 21 and 28 to 30                 
          under
