          Appeal No. 1998-0752                                                        
          Application 08/389,096                                                      


               Rather than repeat the arguments of Appellant or the                   
          Examiner, we make reference to the brief and the answer for                 
          the details thereof.                                                        
                                       OPINION                                        
               After a careful review of the evidence before us, we                   
          agree with the Examiner that claims 9, 11, and 12 are properly              
          rejected under 35 U.S.C. § 103.  Thus, we will sustain the                  
          rejection of these claims; but we will reverse the rejection                
          of the remaining claims on appeal for the reasons set forth                 
          infra.                                                                      
               It is the burden of the Examiner to establish why one                  
          having ordinary skill in the art would have been led to the                 
          claimed invention by the reasonable teachings or suggestions                
          found in the prior art, or by a reasonable inference to the                 
          artisan contained in such teachings or suggestions.  In re                  
          Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6 (Fed. Cir. 1983).                
          In addition, the Federal Circuit states that "[t]he mere fact               
          that the prior art may be modified in the manner suggested by               
          the Examiner does not make the modification obvious unless the              
          prior art suggested the desirability of the modification."  In              

                                          5
