          Appeal No. 2000-1156                                                        
          Application No. 08/578,706                                                  

               Claims 7 through 11 stand rejected under 35 U.S.C. § 103(a)            
          as being unpatentable over the combined teachings of Arraudeau,             
          Denzinger and Sehm.                                                         
               We have carefully reviewed the specification, claims and               
          applied prior art, including all of the arguments and evidence              
          advanced by both the examiner and the appellants in support of              
          their respective positions.  This review leads us to conclude               
          that the examiner’s Section 103 rejection is not well founded.              
          Accordingly, we reverse the examiner’s Section 103 rejection for            
          the reasons set forth by the appellants in their Brief and below.           
               Under 35 U.S.C. § 103, “the examiner bears the initial                 
          burden, on review of the prior art or on any other ground, of               
          presenting a prima facie case of unpatentability.”  In re                   
          Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.               
          1992).  In other words, the examiner must provide a sufficient              
          factual basis to support his Section 103 rejection.  In re                  
          Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177-78 (CCPA 1967),              
          cert. denied, 389 U.S. 1057 (1968), reh’g denied, 390 U.S. 1000             
          (1968).                                                                     
               Here, consistent with the appellants’ assertion, the                   
          examiner has not supplied a sufficient factual basis to establish           
          that one of ordinary skill in the art would have been led to                
                                          3
