                 Appeal No.  2001-0733                                                        Page 6                   
                 Application No. 09/095,429                                                                            

                 acid has been mutated such that certain defined amino acids of SEQ ID NO: 1                           
                 contain an amino acid residue other than that specified by SEQ ID. NO: 1,                             
                 wherein the changes are particularly defined in the body of the claim.                                
                        We can now address the patentability issue under 35 U.S.C. § 103(a)                            
                 based on the above interpretation of the claim.  The burden is on the examiner to                     
                 make a prima facie case of obviousness, and the examiner may meet this                                
                 burden by demonstrating that the prior art would lead the ordinary artisan to                         
                 combine the relevant teachings of the references to arrive at the claimed                             
                 invention.  See In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598-99                               
                 (Fed. Cir. 1988).  The findings of fact underlying the obviousness rejection, as                      
                 well as the conclusions of law, must be made in accordance with the                                   
                 Administrative Procedure Act, 5 U.S.C. 706 (A), (E) (1994). See Zurko v.                              
                 Dickinson, 527 U.S. 150, 158, 119 S.Ct. 1816, 1821, 50 USPQ2d 1930, 1934                              
                 (1999).  Findings of fact underlying the obviousness rejection, upon review by                        
                 the Court of Appeals for the Federal Circuit, must be supported by substantial                        
                 evidence within the record.  See In re Gartside, 203 F.3d 1305, 1315,                                 
                 53 USPQ2d 1769, 1775 (Fed. Cir. 2000).  In addition, in order for meaningful                          


                 appellate review to occur, the examiner must present a full and reasoned                              
                 explanation of the rejection.  See, e.g., In re Lee, 277 F.3d 1338, 1342, 61                          
                 USPQ2d 1430, 1432 (Fed. Cir. 2002).                                                                   
                        In this case, it is hard to determine what is in fact the examiner’s position                  
                 in the statement of the rejection.  Appellants argue that the examiner is relying
