           Appeal No. 2006-2057                                                                     
           Application No. 10/277,482                                                               

                 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); 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. Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ           
           929, 933 (Fed. Cir. 1984).  These showings by the examiner are an essential part of      
           complying with the burden of presenting a prima facie case of obviousness.  Note         
           In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).  If           
           that burden is met, the burden then shifts to the applicant to overcome the prima        
           facie case with argument and/or evidence.  Obviousness is then determined on the         
           basis of the evidence as a whole.  See id.; In re Hedges, 783 F.2d 1038, 1039, 228       
           USPQ 685, 686 (Fed. Cir. 1986); In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ            
           785, 788 (Fed. Cir. 1984); and In re Rinehart, 531 F.2d 1048, 1052, 189 USPQ             
           143, 147 (CCPA 1976).                                                                    
                 We note at the outset appellants’ statement (brief, page 11) that claims 1-14      
           shall stand or fall with the patentability of claim 1.  We further note appellant's      
                                                 5
