          Application No. 07/941,466                                                  


          rejections advanced by the examiner, and the evidence of                    
          obviousness relied upon by the examiner as support for the                  
          rejections.  We have, likewise, reviewed and taken into                     
          consideration, in reaching our decision, the appellants’                    
          arguments set forth in the brief along with the examiner’s                  
          rationale in support of the rejections and arguments in                     
          rebuttal set forth in the examiner’s answer.                                
               It is our view, after consideration of the record before               
          us, that the evidence relied upon and the level of skill in                 
          the particular art would not have suggested to one of ordinary              
          skill in the art the invention as set forth in claims 1-16.                 
          Accordingly, we reverse.                                                    
          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                      
          determin-ations 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
