                      This is a decision on appeal from the final rejection of claims 16-18

                                         STATEMENT OF CASE                                                  
                      Melatonin (N-acetyl-5-methoxytryptamine) is a naturally-occurring

               administered melatonin has been found to be insufficient to regulate sleep
