                examiner’s final rejection of claims 1-11, which are all the claims pending in the            
                application.                                                                                  
                      Claim 1 is illustrative of the subject matter on appeal and is reproduced               
                below:                                                                                        
                   1. A method for identifying a member of a mass-coded molecular library                     
                      which is a ligand for a biomolecule and binds to the biomolecule at the                 
                      binding site of a known second ligand for the biomolecule, said method                  
                      comprising the steps of:                                                                
                      (a) contacting the biomolecule with a mass-coded molecular library, said                
                         mass-coded molecular library comprising compounds of the general                     
                         formula XYn, wherein n is an integer from 2 to about 6, X is a scaffold              
                         and each Y is, independently, a peripheral moiety, wherein there exist               
                         at least about 250 distinct combinations of n peripheral moieties, and               
                         wherein each of at least about 90% of the combinations of n peripheral
