              Application No. 09/182,404                                                                                 


                                                       OPINION                                                           
                     In reaching our decision in this appeal, we have given careful consideration to                     
              appellant's specification and claims, to the applied prior art reference, and to the                       
              respective positions articulated by appellant and the examiner.  As a consequence of                       
              our review, we make the determinations which follow.                                                       
                                                    35 U.S.C. § 102                                                      
                     "Anticipation is established only when a single prior art reference discloses,                      
              expressly or under the 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).                                                                        
                     It is well settled that the burden of establishing a prima facie case of anticipation               
              resides with the Patent and Trademark Office (PTO).  See In re Piasecki, 745 F.2d                          
              1468, 1472, 223 USPQ 785, 788 (Fed. Cir. 1984).  After the PTO establishes a prima                         
              facie case of anticipation based on inherency, the burden shifts to the appellant to                       
              prove that the subject matter shown to be in the prior art does not possess the                            
              characteristics of the claimed invention.  See In re Thorpe, 777 F.2d 695, 698, 227                        
              USPQ 964, 966 (Fed. Cir. 1985); In re King, 801 F.2d 1324, 1327, 231 USPQ 136, 138                         
              (Fed. Cir. 1986).  Hence, appellant’s burden before the PTO is to prove that the applied                   




                                                           3
