              Appeal No. 2001-2124                                                                                        
              Application No. 09/416,914                                                                                  


              particle size in the range of 0.1:m to 100 :m, preferably 1 :m to 10 :m.”  See column 2,                    
              lines 50-52.  We conclude that, the preferred range of core particle, 1 :m to 10 :m,                        

              anticipates the particle size of “about 1 to 100 micrometers” required by the claimed subject               
              matter.                                                                                                     
              As to the particle size of the ultrafines, the appellant has correctly stated that Umeya                    
              teaches an ultrafine having an average particle size in the range of 0.005 :m to 0.5 :m.  See               

              column 2, lines 67-68.  This size corresponds to 5 nm to 500 nm.  We find, however, that                    
              Umeya further discloses that the particle size of the ultrafines is “usually 0.1 :m which                   

              corresponds to 100 nm and is within the scope of the claimed subject matter.”  We further                   
              find that Example 2 discloses core particles having an average particle size of 1:m coated                  
              with an ultrafine having an average particle size of 0.02 :m corresponding to 20 nanometers.                
              We find that, Examples 3 and 4 disclose core particles having a particle size of 40-60 :m                   
              coated with ultrafines having a particle size of 0.01 to 0.05 :m, corresponding to 10 to 50                 

              nm.  Each of the aforementioned examples teaches both core particle size and ultrafine                      
              particle size within the scope of the claimed subject matter.                                               
              Based upon the above findings, we conclude that the teachings and disclosure of                             

              Umeya are sufficient to establish a prima facie case of anticipation with respect to claim 14.              
              The Rejection under § 103(a) of claims 1-6 and 9-12                                                         



                                                            6
