          Appeal No. 2002-0928                                                        
          Application 09/315,251                                                      

          particles. While Ozaki prepares a dispersion of zirconium oxide             
          having a particle size of 5 nanometers in water using ultrasound,           
          there is no evidence in the record which establishes that zirconium         
          oxide of 5 nanometer particle size as dispersed by ultrasound is a          
          "nanostructured material."  Moreover, the dispersion obtained by            
          Ozaki is subsequently dropped into a high boiling liquid to drive           
          off water and form microspheres which ultimately have  a particle           
          size of "about 50 :m." The examiner has not adequately explained            
          why the routineer would have halted Ozaki's process after forming           
          the aqueous dispersion of zirconium oxide by ultrasound and then            
          used the dispersion in Gitzhofer's process for a different purpose          
          than that intended by Ozaki for their process. Accordingly, we find         
          that the examiner has failed to make out a prima facie case of              
          obviousness for the subject matter appellants claim to be their             
          invention. Because we have found the examiner has failed to make            
          out a prima facie case of obviousness, it is unnecessary for our            
          decision to address the declarations under 37 C.F.R. § 1.132 which          
          represent appellants' evidence of non-obviousness.                          
                               NEW GROUND OF REJECTION                                
               Pursuant to our authority under 37 C.F.R. § 1.196(b), we enter         
          the following new ground of rejection. Claims 1 through 5 and 8             
          through 12 are rejected under  the judicially created doctrine of           
          obviousness-type double patenting over the claims in U.S. Patent            
          Number 6,025,034.                                                           

                                          8
