                 Appeal No. 2006-2930                                                                                     
                 Application No. 10/299,198                                                                               


                                                       OPINION                                                            
                         We have carefully considered the subject matter on appeal, the rejection                         
                 advanced by the examiner and the evidence of obviousness relied upon by the                              
                 examiner as support for the rejection.  We have, likewise, reviewed and taken                            
                 into consideration, in reaching our decision, the appellant's arguments set forth in                     
                 the brief 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 have suggested to one                     
                 of ordinary skill in the art the obviousness of the invention as set forth in the                        
                 claims on appeal.  Accordingly, we affirm.                                                               
                         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).  The examiner must articulate reasons for the examiner’s                           
                 decision.  In re Lee, 277 F.3d 1338, 1342, 61 USPQ2d 1430, 1434 (Fed. Cir.                               
                 2002).  In particular, the examiner must show that there is a teaching, motivation,                      
                 or suggestion of a motivation to combine references relied on as evidence of                             
                 obviousness.  Id. at 1343, 61 USPQ2d at 1433-34.  The examiner cannot simply                             
                 reach conclusions based on the examiner’s own understanding or experience -                              


                                                            3
