          Appeal No. 2001-0024                                                        
          Application No. 08/827,285                                 Page 4           


          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 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 appellants' claims.                
          Accordingly, we reverse.                                                    
               We begin with the rejection of claims 3-9, 11-17, 19-25, and           
          35-41 under 35 U.S.C. § 103 as being unpatentable over Bigus in             
          view of Marks.  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
