                  a reference is modifiable nor implying one of ordinary skill                           
                  in the art would modify a reference to reach the claimed                               
                  invention establishes a prima facie case.  MPEP § 2143.01.                             
                  The prima facie case requires a desirable reason to modify a                           
                  reference to reach the claimed invention.  Id.                                         
                        Yet in this rejection conspicuously absent from the                              
                  record is any reason to modify the teachings of ***                                    
                  [Hamilton] to include, e.g., "an effective amount of a                                 
                  heterocyclic compound" of the claimed invention.  Therefore                            
                  the rejection is improper and should be reversed.                                      

                        23. The examiner provided a complete answer to                                   
            applicants' argument by referring in the Examiner's Answer                                   
            (Paper 12, page 3, line 1) to col. 14, lines 6-16 of Hamilton.                               
            There Hamilton states:                                                                       
                        The present invention also relates to a pharmaceutical                           
                  composition comprising:                                                                
                        (i) a neurotrophically effective amount of the                                   
                  compound of formula I, II, III or IV, and                                              
                  (ii) a pharmaceutically acceptable carrier.                                            

                        24. The examiner also called attention to                                        
            columns 2-14.  Col. 12, line 4 also describes the use of a                                   
            neurotrophically effective amount of a compound of formula I, II,                            
            III or IV.  A neurotrophically effective amount is a "an                                     
            effective amount" of a compound. 10                                                          





            10   We believe applicants' sole argument for reversal with respect to                       
            Hamilton also borders on frivolous.  In this respect, we again note no reply                 
            brief was filed to respond to the Examiner's Answer.                                         
                                                 - 7 -
