          Appeal No. 1997-3392                                                        
          Application 08/297,946                                                      


               Accordingly, we find that the examiner has not carried                 
          the burden of establishing that all of the limitations of the               
          appellants’ claim 25 are found in the applied reference.                    
          Hence, we reverse the rejection under 35 U.S.C. § 102(b).                   
                           Rejection under 35 U.S.C. § 103                            
               Cunningham discloses a process for making a toner having               
          a high molecular weight polymer contained in a matrix of lower              
          molecular weight polymer (col. 5, lines 55-62).  Cunningham                 
          teaches that “the starved feed monomer is not more hydrophilic              
          than the existing polymer/monomer particle to ensure that the               
          starved feed monomer diffuses into the interior of the                      
          particle and does not form a shell around the exterior of the               
          particle” (col. 4, lines 7-11).                                             
               The examiner argues that Cunningham’s process steps and                
          materials are the same as those of the appellants and that,                 
          therefore, the appellants’ toner morphologies must be obtained              
          using Cunningham’s process (answer, pages 9-10 and 18-24).                  
               The appellants, however, disclose that variation of the                
          starting time of the starved feed addition can be used to                   
          control the polymer morphology such that, inter alia, a
