          Appeal No. 1997-2158                                       Page 5           
          Application No. 08/234,239                                                  


               We begin by noting the following principles from In re                 
          Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956 (Fed. Cir.               
          1993).                                                                      
               In rejecting claims under 35 U.S.C. Section  103,                      
               the examiner bears the initial burden of presenting                    
               a  prima facie case of obviousness.  In re Oetiker,                    
               977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.                   
               1992). Only if that burden is met, does the burden                     
               of coming  forward with evidence or argument shift                     
               to the applicant.  Id.  "A prima facie case of                         
               obviousness is established when the teachings from                     
               the prior art itself would appear to have suggested                    
               the claimed subject matter to a person of ordinary                     
               skill in the art."  In re Bell, 991 F.2d 781, 782,                     
               26 USPQ2d 1529, 1531 (Fed. Cir. 1993) (quoting In re                   
               Rinehart, 531 F.2d 1048, 1051, 189 USPQ 143, 147                       
               (CCPA 1976)). If the examiner fails to establish a                     
               prima facie case, the rejection is improper and will                   
               be overturned.  In re Fine, 837 F.2d 1071, 1074, 5                     
               USPQ2d 1596, 1598 (Fed. Cir. 1988).                                    
          With these in mind, we analyze the appellants’ arguments.                   


               The appellants’ argument follows.                                      
               Virus instructions, such as "Jump" instructions,                       
               page 7, line 15 et seq., are exemplary forms of data                   
               indicative of invalidity that can appear within                        
               multiple unrelated programs and data files, and bear                   
               no relationship to Francisco's unique EIDs that are                    
               separate from and uniquely associated with a single                    
               program.  For this reason, the Examiner's                              
               interpretation of the claimed "forms of data                           
               indicative of invalidity" is also expressly contrary                   
               to the definition provided in the instant
