          Appeal No. 2000-0274                                                        
          Application No. 08/724,568                                                  


                                       OPINION                                        
               We have carefully considered the entire record before us,              
          and we will reverse the obviousness rejection of claims 1                   
          through 10, 13, 15, 18 and 20.                                              
               According to the examiner (answer, page 4), “[t]he                     
          admitted prior art includes all the claimed limitations except              
          for the claimed receiving a message length command (indicating              
          the length of the pending message) which is used to determine               
          if there is sufficient memory in the receiver,” “Faris shows a              
          system in which the memory full determination is based upon                 
          the length of an incoming message,” and “Hamamoto shows a                   
          system in which the transmitter transmits a message length                  
          command to indicate the length of a pending message.”  Based                
          upon the teachings of the admitted prior art, Faris and                     
          Hamamoto, the examiner contends (answer, page 4) that “it                   
          would have been obvious to one of ordinary skill in the art at              
          the time of the invention to have utilized a message length                 
          command to assist in determining if there is sufficient memory              
          in the receiver of the admitted prior art system, since this                
          would make the admitted prior art system accurate and user                  
          friendly (more automated).”                                                 
                                          7
