          Appeal No. 1999-0260                                                        
          Application 08/571,064                                                      
               Rather than reiterate the arguments of Appellants and the              
          Examiner, reference is made to the Brief,1 Reply Brief,2 Final              
          Rejection3 and the Examiner's Answer4 for the respective details            
          thereof.                                                                    
                                       OPINION                                        
               We will not sustain the rejection of claims 1-9 and 13-18              
          under 35 U.S.C. § 103.                                                      
               The Examiner has failed to set forth a prima facie case.  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 express teachings or suggestions found                     
          in the prior art, or by implications contained in such teachings            
          or suggestions.  In re Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6           
          (Fed. Cir. 1983).  The Federal Circuit states that                          
               "[t]he mere fact that the prior art may be modified in                 
               the manner suggested by Examiner does not make the                     
               modification obvious unless the prior art suggested the                
               desirability of the modification."                                     
                                                                                     


               1 The Brief was received April 6, 1998                                 
               2 The Reply Brief was received July 22, 1998                           
               3 The Final Rejection was mailed October 15, 1997                      
               4 The Examiner's Answer was mailed May 19, 1998                        
                                          4
