          Application No. 08/262,400                                                  


          examiner and the appellants as set forth in the Answer and the              
          Brief.                                                                      
                       The Rejection Under 35 U.S.C. § 102(b)                         
               The guidance provided by our reviewing court with regard               
          to the matter of anticipation is as follows:  Anticipation is               
          established only when a single prior art reference discloses,               
          either expressly or under the principles of inherency, each                 
          and every element of the claimed invention.  See In re                      
          Paulsen, 30 F.3d 1475, 1480-1481, 31 USPQ2d 1671, 1675 (Fed.                
          Cir. 1994) and In re Spada, 911 F.2d 705, 708, 15 USPQ2d 1655,              
          1657 (Fed. Cir. 1990).  Anticipation by a prior art reference               
          does not require either the inventive concept of the claimed                
          subject matter or recognition of inherent properties that may               
          be possessed by the reference.  See Verdegaal Brothers Inc. V.              
          Union Oil Co. Of California, 814 F.2d 628, 633, 2 USPQ2d 1051,              
          1054 (Fed. Cir. 1987).  The law of anticipation does not                    
          require that the                                                            
          reference teach what the applicant is claiming, but only that               
          the claim on appeal "read on" something disclosed in the                    
          reference, i.e., all limitations of the claim are found in the
