          Appeal No. 2001-1461                                                        
          Application 08/921,130                                                      

               Claims 5 and 123 stand rejected under 35 U.S.C. § 103(a) as            
          being unpatentable over Gardner.                                            
               We refer to the final rejection (Paper No. 7) (pages                   
          referred to as "FR__") and the examiner's answer (Paper No. 12)             
          (pages referred to as "EA__") for a statement of the examiner's             
          rejection, and to the brief (Paper No. 11) (pages referred to as            
          "Br__") and reply brief (Paper No. 13) (pages referred to as                
          "RBr__") for a statement of appellants' arguments thereagainst.             
                                       OPINION                                        
               "Anticipation is established only when a single prior art              
          reference discloses, expressly or under principles of inherency,            
          each and every element of a claimed invention."  RCA Corp. v.               
          Applied Digital Data Systems, Inc., 730 F.2d 1440, 1444,                    
          221 USPQ 385, 388 (Fed. Cir. 1984).  Inherency requires that a              
          characteristic or property necessarily be in the prior art                  
          reference.  See In re Rijckaert, 9 F.3d 1531, 1534,                         
          28 USPQ2d 1955, 1957 (Fed. Cir. 1993) ("The mere fact that a                
          certain thing may result from a given set of circumstances is not           
          sufficient [to establish inherency])."  The initial burden of               
          establishing a prima facie case of inherency by evidence or                 
          persuasive reasoning is on the examiner.  See In re Schreiber,              
          128 F.3d 1473, 1478, 44 USPQ2d 1429, 1432 (Fed. Cir. 1997).                 


          3  See footnote 2.
