          Appeal No. 2002-2082                                                        
          Application No. 09/289,393                                 Page 4           


          the examiner as support for the rejection.  We have, likewise,              
          reviewed and taken into consideration, in reaching our decision,            
          appellants' arguments set forth in the briefs along with the                
          examiner's rationale in support of the rejection 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 5-7, 9, and 10.             
          Accordingly, we reverse, essentially for the reasons set forth by           
          appellants.                                                                 
          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
