EDWARDS et al. V. LEVEEN - Page 5






           Interference No. 104,290                                                            



           Edwards based on lack of descriptive support under 35 U.S.C.                        
           § 112, first paragraph. Since Edwards' only claim in the                            
           interference had been determined to be unpatentable to Edwards,                     
           the panel first ruled that junior party LeVeen need not put on                      
           a priority case.                                                                    
                      The panel subsequently modified its ruling and required                  
           junior party to prove priority, because, notwithstanding the lack                   
           of written description for Edwards' claim, the Edwards specifica                    
           tion still appears to be a constructive reduction to practice of                    
           at least one embodiment falling within the scope of the count.                      
           In this new order, 6 Edwards was permitted to argue abandonment,                    
           suppression, or concealment at final hearing, to attack LeVeen's                    
           evidence of conception, reduction to practice, and diligence, and                   
           to introduce rebuttal evidence.                                                     


           Issues                                                                              

                      The following issues are raised by the parties in their                  
           briefs:                                                                             
                      a) has junior party LeVeen established an actual                         
           reduction to practice before the effective filing date of the                       



                  Paper No. 2ý0.
