              Appeal No. 1999-0080                                                                                     
              Application No. 08/558,929                                                                               


                     In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden of               
              presenting a prima facie case of obviousness.  See In re Rijckaert, 9 F.3d  1531, 1532,                  

              28 USPQ2d 1955, 1956 (Fed. Cir. 1993).  A prima facie case of obviousness is                             
              established by presenting evidence that the reference teachings would appear to be                       
              sufficient for one of ordinary skill in the relevant art having the references before him to             
              make the proposed combination or other modification.  See In re Lintner, 9 F.2d 1013,                    

              1016, 173 USPQ 560, 562 (CCPA 1972).  Furthermore, the conclusion that the claimed                       
              subject matter is prima facie obvious must be supported by evidence, as shown by                         
              some objective teaching in the prior art or by knowledge generally available to one of                   
              ordinary skill in the art that would have led that individual 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 (Fed. Cir. 1988).                                                                    
                     The examiner states that “[i]t would have been obvious to one of ordinary skill in the            
              art to execute the boot-up routine and then the enabler file so that system compatibility can            
              be determined before loading lengthy operating system code” (Office action at page 4 as                  
              incorporated by the examiner at page 5 of the answer), but the examiner provides no                      
              support or motivation in the prior art applied for this conclusion.                                      






                                                          4
