          Appeal 97-1804                                                              
          Application 08/329,042                                                      

          qualified to give expert opinion in the field of                            
          photoconductors.                                                            
                    27. Dr. Nguyen states (First Declaration, ¶ 11):                  
               I have physically examined binder layers for organic                   
               photoconductors made according to the methods disclosed                
               in this application.  These layers appear to be smooth,                
               continuous films without pores.                                        

                    28. Dr. Nguyen, responding to the examiner's                      
          rejection based on Hens, states (First Declaration, ¶ 13):                  
               [A] necessary feature of an organic photoconductor layer               
               is that it be non-porous because pores in the layer will               
               adversely affect electrical charge acceptance and                      
               retention.                                                             

                    29. Basically, Dr. Nguyen is saying that the compact              
          of Hens will not function as a OPC.                                         
                    30. The examiner found that the addition of                       
          "continuous, non-porous" was "new matter" and rejected the                  
          claims on the ground that the claimed subject matter was not                
          described in the application, as filed (Final Rejection, Paper              
          14, page 2).                                                                
                    31. The examiner also maintained the anticipation                 
          rejection based on Hens.                                                    
                                        - 9 -
