          Appeal No. 2001-1799                                                        
          Application 09/097,655                                                      

          group [brief, page 4].  Consistent with this indication                     
          appellants have made no separate arguments with respect to any of           
          the claims on appeal.  Accordingly, all the claims before us will           
          stand or fall together.  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).  Therefore, we will consider           
          the rejection against independent claim 1 as representative of              
          all the claims on appeal.                                                   
          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           
                                          5
