          Interference No. 102,922                                                    
          Interference No. 103,088                                                    
          above noted Dumas application Ser. No. 07/748,486 assigned to               
          Hercules, and a U.S. patent No. 5,147,507 filed on behalf of                
          Gill, originally assigned to Pfizer and now assigned to                     
          Mineral Technologies, Inc.  This second interference was                    
          declared as a result of a Dumas 37 CFR § 1.633(c)(1) motion in              
          ‘922 requesting that count 3 directed to a method of making                 
          paper and paperboard be added to ‘922.  Since the involved                  
          Gill application in ‘922 did not contain claims directed to                 
          such method but Gill's divisional application, U.S. patent                  
          5,147,507 did, the Administrative Patent Judge (APJ) treated                
          the Dumas motion as a motion to declare another interference                
          directed to the method, granted the motion, and declared the                
          second interference.                                                        
               The subject matter in issue in the ‘088 interference                   
          comprises a process of making paper or paperboard employing                 
          the                                                                         




          surface treated filler of the ‘922 interference.  The count is              
          set forth in APPENDIX B.  Dumas claim 16 and Gill claims 1 and              
          2 correspond to the count.                                                  
               No questions of interference-in-fact or separate                       
                                          4
