          Appeal No. 1998-1970                                                        
          Application No. 08/587,134                                                  

          the applied prior art reference, and to the respective                      
          positions articulated by appellants and by the examiner.  As a              
          consequence of this review, we have made the following                      
               Before addressing the examiner's rejection specifically,               
          we note that on page 4 of the brief, appellants have indicated              
          that ?claim 14 is more limited than claim 13" and thus "more                
          patentable than claim 13."  In contrast to the examiner, we                 
          understand this statement by the appellants to indicate that                
          claims 13 and 14 should not be grouped together.  Therefore we              
          shall treat claims 13 and 14 separately.                                    
               An anticipation under 35 U.S.C. 102(b) is established                  
          when a single prior art reference discloses, either expressly               
          or under principles of inherency, each and every element of a               
          claimed invention.  See RCA Corp. v. Applied Digital Data                   
          Systems, Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed.                 
          Cir. 1984).                                                                 
          However, we observe that the law of anticipation does not                   
          require that the reference teach what the appellant has                     
          disclosed but only that the claims on appeal "read on"                      
          something disclosed in the reference, i.e., all limitations of
