         Appeal No. 2003-1788                                                       
         Application No. 09/403,081                                                 



         I.  The Anticipation Rejection                                             
              We note that the initial burden of presenting a prima facie           
         case of unpatentability on any ground rests with the examiner.             
         See In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444               
         (Fed. Cir. 1992).  To meet this burden, with regard to an                  
         anticipation rejection, the examiner must establish that a single          
         prior art reference discloses each and every material element of           
         the claim.  In re Marshall, 578 F.2d 301, 304, 198 USPQ 344, 346           
         (CCPA 1978).                                                               
              Critical to the anticipation issue in this appeal is the              
         definition of “burner”.  The examiner states: “[n]o distinction            
         is seen or has been shown in the manner in which the appellants            
         add supplemental oxygen . . . into their region 8 . . . as                 
         compared to the manner in which Gitman adds supplemental air . .           
         . into their region 102.”  Answer, page 8.                                 
              On the other hand, appellants state: “[t]he region 102                
         illustrated in Fig. 2 of Gitman and the region 8 illustrated in            
         Figs. 1-3 of the present application have clearly different                
         functions.  Region 8 . . . is a combustion reactor (reaction               
         chamber).  The combustion reactor permits the chemical components          
         to react with each other as completely as possible.”  Brief, page          
         7.                                                                         
              We find that Gitman introduces oxygen to preliminary burner           
         17 and to chambers 101 and 102, which are depicted as part of              
         burner means 16, in Figure 2 of Gitman.  It is reaction chamber 3          
         that is separate, downstream, and apart from burner means 16.              
         See Figure 2 of Gitman.                                                    
              We also find in Gitman that feed gas can be introduced into           
         both the preliminary burner 17 (via line 5), and the chamber 102,          
         (via line 108), of Gitman.  See Figure 2 and page 22, lines 20-22          
         of Gitman.                                                                 
                                         3
