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


                    hold ink. Once all the activated points                            
                    have been charged, the print form is used                          
                    to print the desired image. This circuit                           
                    arrangment [sic, arrangement] of the <048                          
                    patent ?activates and de-activates regions                         
                    of a surface matrix? as claimed. The                               
                    transistors used in <048 act as the recited                        
                    ?threshold value switches?. As is                                  
                    conventional in the art of electronic                              
                    switching, transistors are used to switch                          
                    between on and off states. When no voltage                         
                    is applied to the gate of the transistors,                         
                    they are in a non-conducting (high                                 
                    resistance or off) state. When a positive                          
                    voltage is applied to the gates of the                             
                    transistors in the <048 circuit, the                               
                    transistors are in a low resistance                                
                    conducting ?on? state. Therefore the                               
                    transistors in <048 act as the recited                             
                    ?threshold value switches?. [Answer, page                          
                    3.]                                                                


               We have carefully considered the issues raised in this                  
          appeal together with the examiner’s remarks and appellant’s                  
          arguments. As a result, we will sustain the rejection of                     
          claims 1 through 12 and 14 through 30, but not the rejection                 
          of claim 13.                                                                 


               In presenting various arguments in the argument section                 
          commencing on page 26 of the brief, appellant does not                       
          expressly refer to any particular claim with the exception of                
                                           4
