            Appeal No. 2006-2723                                                                           
            Application No. 09/891,264                                                                     

            We have, likewise, reviewed and taken into consideration, in reaching our                      
            decision, Appellant’s 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.                                                                             
                  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, 17-18, 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, knowledge generally           
            available to one having ordinary skill in the art or the nature of the problem to be           
            solved.  In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d 1614, 1617 (Fed. Cir.                   
            1999); Uniroyal, Inc. v. Rudkin-Wiley Corp., 837 F.2d 1044, 1051, 5 USPQ2d                     
            1434, 1438 (Fed. Cir. 1988); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc.,           
            776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985); ACS Hosp. Sys., Inc. v.                 
                                                    4
