          Appeal No. 1997-0339                                                        
          Application 08/330,768                                                      


          invention captures the test signal for testing and provides                 
          for testing both a true and complement data signal, rather                  
          than just one of them as in the prior art, since either one or              
          both may be corrupted.                                                      
               The invention is further illustrated below by claim 1.                 
               1.   A test circuit comprising:                                        
               means for selecting from a data path a test signal from                
          amount a true data signal and a complement data signal; and                 
               means for capturing said test signal for testing.

           103 over Rickard.  Claim 9 stands rejected under 35 U.S.C.                
           103 over Rickard and Dervisoglu.                                          
               Reference is made to Appellants’ brief and the Examiner's              
          answer and for their respective positions.
