          Interference No. 102,622                                                    

                      ABANDONMENT, SUPPRESSION AND CONCEALMENT                        
                    On June 5, 1992, Rivetti et al. filed notice that                 
          they intended to argue that Oates abandoned, suppressed or                  
          concealed an actual reduction to practice as required by 37                 
          C.F.R. § 1.632. See Paper Number 41.                                        
                    Nevertheless, "without an actual reduction to                     
          practice there is no invention in existence which can be                    
          abandoned, suppressed, or concealed."  Peeler v. Miller, 535                
          F.2d at 651, 190 USPQ at 120.  Because Oates has not presented              
          any evidence of priority based on an actual reduction to                    
          practice, it is Rivetti et al.'s burden to establish by a                   
          preponderance of the evidence that Oates abandoned, suppressed              
          or concealed her invention within the meaning of 35 U.S.C. §                
          102(g).  Gallagher v. Smith, 206 F.2d 939, 99 USPQ 132 (CCPA                
          1953).                                                                      
                    We agree with Oates for reasons expressed in her                  
          reply brief at page 4 thereof that Rivetti et al. have failed               
          to prove that Oates actually reduced to practice an embodiment              
          within the Count at a time prior to Rivetti et al.'s Italian                
          application benefit date of March 4, 1988.                                  


                                      JUDGMENT                                        
                                         18
