          Appeal No. 2004-1461                                                        
          Application No. 09/461,883                                                  

          with respect to the dependent claims, the dependent claims will             
          stand or fall with the claims from which they respectively                  
          depend.  Note In re King, 801 F.2d 1324, 1325, 231 USPQ 136, 137            
          (Fed. Cir. 1986); In re Sernaker, 702 F.2d 989, 991, 217 USPQ 1,            
          3 (Fed. Cir. 1983).                                                         
          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. 1988), cert. denied, 488               
          U.S. 825 (1988); Ashland Oil, Inc. v. Delta Resins &                        
          Refractories, Inc.,
