                judicially created doctrine of obviousness-type double patenting as                           
                unpatentable over claims 1, 2, 4-21, 24, 36-38, and 40-46 of US Patent

                                                    Issue                                                     
                      Has the Examiner identified the portions of the references that teach                   
                or suggest the process of the presently claimed invention?  More                              
                specifically, has the Examiner identified any teaching or suggestion in the                   
                cited references that indicates controlling the amount of dye incorporated                    
                into microparticles is achieved by controlling a tuning solvent?  We answer                   
                these questions in the negative.                                                              
                                                  Analysis                                                    
                      The subject matter of independent claims 1 and 9 relates to methods                     
                of generating a plurality of microparticle populations of different dye                       
                concentrations where dye is loaded into polymer microparticles to generate                    
                said microparticle populations.  Each of the claims utilize a three-solvent                   
                (ternary) system wherein the extent of the loading of the dye into the                        
                microparticles is controlled by adjusting the solvency of the suspension by                   
                controlling the amount of tuning solvent utilized.  Thus, in order to achieve a               
                new color variation, the amount of dye incorporated into the microparticle is                 
                controlled by increasing or decreasing the amount of tuning solvent utilized                  
                in the suspension.
