                Appeal 2007-2035                                                                                  
                Application 09/848,846                                                                            
                                                                                                                 
                       The Examiner relies on the following prior art reference to show                           
                unpatentability:                                                                                  
                Lowrey                      US 5,252,504               Oct. 12, 1993                              

                       Claims 11, 12, and 14 stand rejected under 35 U.S.C. § 103(a) as                           
                unpatentable over Lowrey.                                                                         
                       Rather than repeat the arguments of Appellant or the Examiner, we                          
                refer to the Brief and the Answer for their respective details.  In this                          
                decision, we have considered only those arguments actually made by                                
                Appellant.  Arguments which Appellant could have made but did not make                            
                in the Brief have not been considered and are deemed to be waived.  See 37                        
                C.F.R. § 41.37(c)(1)(vii).                                                                        

                                                   OPINION                                                        
                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 must make the factual                                
                determinations set forth in Graham v. John Deere Co., 383 U.S. 1, 17, 148                         
                USPQ 459, 467 (1966).                                                                             
                       Discussing the question of obviousness of a patent that claims a                           
                combination of known elements, KSR Int’l v. Teleflex, Inc., 127 S. Ct. 1727,                      
                82 USPQ2d 1385 (2007) explains:                                                                   
                       When a work is available in one field of endeavor, design                                  
                       incentives and other market forces can prompt variations of it,                            
                       either in the same field or a different one.  If a person of                               
                       ordinary skill can implement a predictable variation, §103                                 

                                                        3
