              Appeal No. 1998-1801                                                                                      
              Application No. 08/285,411                                                                                

                     The allocation of burdens requires that the USPTO produce the factual basis for its                
              rejection of an application under 35 U.S.C. § § 102 and 103.  In re Piasecki, 745 F.2d                    
              1468, 1472, 223 USPQ 785, 788 (Fed. Cir. 1984) (citing In re Warner, 379 F.2d 1011,                       
              1016, 154 USPQ 173, 177 (CCPA 1967)).  The one who bears the initial burden of                            
              presenting a prima facie case of unpatentability is the examiner.  In re Oetiker, 977 F.2d at             
              1445, 24 USPQ2d at 1444.  The reference as applied is not sufficient to establish prima                   
              facie obviousness of the claimed subject matter as a whole, in view of appellants’                        
              unanswered arguments.  We therefore cannot sustain the section 103 rejection of the                       
              claims.                                                                                                   


                                                    CONCLUSION                                                          
                     The rejection of claims 18-21 is reversed.
