          Appeal No. 95-0865                                                           
          Application 08/08/007,950                                                    















          with a Compound XIII (the one on the left side), which has the               
          formula:                                                                     







                    27. A person having ordinary skill in the art would                
          immediately recognize that the formula of Compound XII, as set               
          out on page 16 of Hagberg I is erroneous in that a double bond is            
          missing between the 7- and 8-positions in the ring and a hydrogen            
          (H) is missing from the nitrogen (N) at the 9-position.  See,                
          e.g., page 56, formula XII which shows the necessary double bond             
          between the 7- and 8-positions and an NH at the 9-position.  See             


                                        - 14 -
