          Appeal No. 1997-2246                                                        
          Application 08/353,572                                                      

          assertion of diligence is not directed to a period commencing               
          from a time “prior” to September 12, 1988.                                  
               The appellants’ reply further states:                                  
               One of the exhibits that was submitted was:                            
               Exhibit A5: a filed test report prepared prior to                      
               September 12, 1988 which reports on tests performed                    
               prior to September 12, 1988 of a system which                          
               incorporates the subject invention[“].                                 
          The examiner in his supplemental examiner’s answer (Paper No.               
          24) correctly notes on page 5 thereof that tests conducted                  
          prior to September 12, 1988 cannot provide evidence of                      
          diligence from September 12, 1988 to March 16, 1989.                        
          Moreover, the appellants’ reply does not address how long                   
          prior to September 12, 1988 were the tests performed.                       
               The examiner further found that the appellants have not                
          demonstrated any actual reduction to practice of the claimed                
          invention subsequent to the effective filing date of the                    
          Schwendeman reference (Paper No. 21 at page 3).  The                        
          appellants dispute that finding (Reply Point 5 at pages 2-3).               
          We need not and do not reach this issue, because we sustain                 
          the examiner’s conclusion that the appellants have not shown                
          reasonable diligence from a time prior to the effective filing              
          date of the Schwendeman reference to the time of alleged                    
                                         14
