          Appeal No.  2005-2618                                                       
          Application No.  10/060,494                                                 

                                       OPINION                                        
               A rejection for anticipation requires that the four corners            
          of a single prior art document describe every element of the                
          claimed invention, either expressly or inherently, such that a              
          person of ordinary skill in the art could practice the invention            
          without undue experimentation.  See Atlas Powder Co. v. Ireco               
          Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999);           
          In re Paulsen, 30 F.3d 1475, 1478-79, 31 USPQ2d 1671, 1673 (Fed.            
          Cir. 1994).                                                                 
               Appellant acknowledges that the data card 232-1 described in           
          Bonora has light emitters as it communicates with the                       
          communication means 236 which includes photodetectors and                   
          responds to data transmitted by light emitting diode (brief, page           
          12).  Appellant further argues that both units have LEDs used for           
          serial communication of data from one piece of equipment to                 
          another instead of the visual direct communication to a human               
          operator without the use of an intermediary photodetector, as               
          recited in claim 1 (brief, page 15).                                        
               In response, the Examiner relies on the discussion of a                
          display in Bonora (col. 9, lines 2-11) and the teachings related            
          to the communications means 236 (col. 8, lines 40-46) and                   
          characterizes the operator’s interaction with the container                 
                                          3
