          Appeal No. 1996-2738                                                        
          Application 08/252,501                                                      


          the Solicitor appears to suggest - that regardless of how                   
          broad, a disclosure of a chemical genus renders obvious any                 
          species that happens to fall                                                
          within it.”  In re Jones, 958 F.2d 347, 350, 21 USPQ2d 1941,                
          1943 (Fed. Cir. 1992).  Here the examiner has failed to                     
          establish why one of ordinary skill in the art would have been              
          led to the specific polyamines of the formula recited in claim              
          32 on appeal from the generic disclosure of Hofreiter.                      
          Accordingly, we determine that the examiner has not                         
          established a prima facie case of obviousness and the                       
          rejection of claims 32-38 under 35 U.S.C. § 103 over Hofreiter              
          is reversed.                                                                




               The decision of the examiner has been affirmed-in-part.                
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under 37 CFR                    
          § 1.136(a).                                                                 
          AFFIRMED-IN-PART                                                            



                                          12
