          Appeal No. 95-3641                                                          
          Application 07/992,069                                                      


          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.), cert. denied, 488 U.S. 825           
          (1988); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc.,             
          776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert.                
          denied, 475 U.S. 1017 (1986); ACS Hospital Systems, Inc. v.                 
          Montefiore Hospital, 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).                                                
          With respect to claims 1-8, the examiner’s rejection                        
          notes that WP 5.1 has the ability to store data files in either a           
          version specific format or in ASCII format which is a version               
          independent format.  Although WP 5.1 typically only stores files            
          in a single one of the formats, the examiner observes that files            
          in WP 5.1 can be automatically stored and retrieved in different            
          formats using conventional macros.  The examiner concludes that             
          it would have been obvious to the artisan to use the features of            

                                          5
