          Appeal No. 1997-2184                                                        
          Application 08/278,441                                                      

          failing to comply with the second paragraph of the statute.                 
               Here, the examiner has merely announced that he does not               
          understand what substituents are intended by the terminology                
          used in the claims, that is, the examiner does not understand               
          what are the "non-interfering substituents" R  and R .6      7                       
          Moreover, although the examiner does not precisely reference                
          the exact claim term to which he objects, the examiner                      
          expresses his concerns by stating at page 3 of his Answer                   
               "[w]hat are the numbers 1-10 for La? What linker groups                
               are intended? Are 1-10 oxygens, sulfur, carbon, nitrogen,              
               Se, P, Ge, Pb also intended? Thus, the claims are                      
               indefinite."                                                           
          Neither expressed ground serves as a basis for sustaining                   
          either rejection.                                                           
               As we have stated above, the question to be resolved is                
          whether the hypothetical person of ordinary skill in the                    
          relevant art, having read appellants' specification, would                  
          have been able to determine the scope of appellants'                        
          invention.  Appellants have stated that the meaning intended                
          for the term "non-interfering substituent" was a substituent                
          which does not interfere with the compounds' sPLA  inhibiting               
                                                           2                          
          properties (see page 5 of the brief). Considered with the list              


                                          6
