                Appeal 2007-0961                                                                                 
                Application 10/264,131                                                                           
                                                   OPINION                                                       
                       Claims 9 and 11 -- § 102(b) over Daniel                                                   
                       Daniel describes an interactive display screen (Fig. 1) having a matrix                   
                of elements addressed by line and column (L, C) electrodes.  A control                           
                element X receives detection signals from element Re, which is associated                        
                with image element P.  An image element P may be controlled by the                               
                electrodes and by control circuit X.  Daniel 3:23 - 4:2.  The image element P                    
                may thus be actuated by either or both of electrodes L, C and receiver Re.                       
                Receiver Re can be sensitive to radiation from a mobile emitter E (Figs. 2                       
                and 3).  Id. 4:3-14, 21-24.  Emitter E is capable, in addition, of transmitting                  
                coded orders to designated zones of the screen that can be decoded and                           
                executed by circuits X.  Id., ll. 25-31.  One may thus, for example, draw                        
                lines, having user-selectable colors, upon the screen.  Id. 5:13-29.                             
                       The emitter can thus be used to superimpose information on a pre-                         
                existing image.  Daniel 6:3-5.  The reference also describes circuit X as                        
                containing a decoder D (Fig. 5) that can receive and decode coded signals                        
                received in the first instance by receiver Re, in addition to signals received                   
                from decoupling circuits DC1 and DC2 from the line and column electrodes.                        
                The signals may relate to a particular image element P.  A particular circuit                    
                X also decodes signals intended for other image elements, which are                              
                transmitted through coupling circuits to the line and column electrodes, for                     
                reception by the intended X circuit and associated image element.  Daniel                        
                6:21 - 7:3.                                                                                      
                       The Examiner finds instant claim 9 to be anticipated by Daniel.  The                      
                Examiner reads the first pulse density capture circuit on the decoupling                         
                circuits, and the second pulse density capture circuit on the combination of                     

                                                       4
