          Appeal No. 1999-1480                                                        
          Application No. 08/523,330                                                  


          (see In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956               
          (Fed. Cir. 1993); In re Oetiker, 977 F.2d 1443, 1445, 24                    
          USPQ2d 1443, 1444 (Fed. Cir. 1992)), which is established when              
          the teachings of the prior art itself would appear to have                  
          suggested the claimed subject matter to one of ordinary skill               
          in the art (see In re Bell, 991 F.2d 781, 783, 26 USPQ2d 1529,              
          1531 (Fed. Cir. 1993)).  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).                                                      


               With this as background, we turn to the examiner’s                     
          rejections under 35 U.S.C.  103(a) as being unpatentable over              
          McRae in view of Taylor of independent claim 52 and claims 53-              
          56 dependent therefrom.                                                     


               We agree with the appellant that all the limitations                   
                                          12
