                                 GROUND OF REJECTION                                  
                    Claims 10-15, 20 and 21 stand rejected under 35 U.S.C.            
          § 103 as unpatentable over Billig in view of Baker I and Baker              
          II.1

                    The invention is directed to a catalyst precursor                 
          composition which is useful in hydrocyanation reactions involving           
          unactivated monoolefins.  Appeal Brief, Paper No. 10, received              
          June 18, 1997, page 2.  The catalyst precursor compositions                 
          comprise a zero-valent nickel and a bidentate phosphite ligand              
          according to Formulas I (claims 10-15) and II-VI (claims 20-21).            
          These ligands are all unsymmetrical and substituted.  See id.,              
          page 4.
