          Appeal No. 1998-0488                                                        
          Application No. 08/496,234                                                  


          We now consider the rejection of claims 1-20 under                          
          35 U.S.C.  103 as unpatentable over the teachings of Brunner,              
          Harrington, Brovman and Kishner.  In rejecting claims under                 
          35 U.S.C.  103, it is incumbent upon the examiner to                       
          establish a factual basis to support the legal conclusion of                
          obviousness.  See In re Fine, 837 F.2d 1071, 1073, 5 USPQ2d                 
          1596, 1598 (Fed. Cir. 1988).  In so doing, the examiner is                  
          expected to make the factual determinations set forth in                    
          Graham v. John Deere Co., 383 U.S. 1, 17, 148 USPQ 459, 467                 
          (1966), and to provide a reason why one having ordinary skill               
          in the pertinent art would have been led to modify the prior                
          art or to combine prior art references to arrive at the                     
          claimed invention.  Such reason must stem from some teaching,               
          suggestion or implication in the prior art as a whole or                    
          knowledge generally available to one having ordinary skill in               
          the art.  Uniroyal, Inc. v. Rudkin-Wiley Corp., 837 F.2d 1044,              
          1051, 5 USPQ2d 1434, 1438 (Fed. Cir.), cert. denied, 488 U.S.               
          825 (1988); Ashland Oil, Inc. v. Delta Resins & Refractories,               
          Inc., 776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985),                
          cert. denied, 475 U.S. 1017 (1986); ACS Hosp. Sys., Inc. v.                 
          Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ 929, 933 (Fed.              

                                          9
