          Appeal No. 96-3101                                                           
          Application 08/020,570                                                       


          Patent No. 5,109,240.                                                        


               On pages 27-29 of the brief, appellant asserts that the                 
          use of a threshold value switch as an addressing device has an               
          advantage which is lacking in the addressing circuit of the                  
          European patent document. In particular, appellant asserts on                
          page 29 of the brief that:                                                   


                    [u]sing such a threshold value switch as an                        
                    addressing device has the significant                              
                    advantage that the threshold value switch,                         
                    once it has been addressed by the voltage                          
                    pulse, ?remembers? that is [sic, it] has                           
                    been selected and in this manner it                                
                    maintains the selected matrix point in the                         
                    selected state until it is later turned                            
                    off.                                                               


               With further regard to this addressing feature, appellant               
          states:                                                                      






                    When a new image is to be printed, the                             
                    plate is again being addressed, and                                
                                           7
