CHRIST et al. V. BLAKE - Page 28




          Interference No. 103,435                                                    




          inequitable conduct on the part of its opponent bears a burden              
          of proving its case by clear and convincing evidence.  Refac                
          Int’l, Ltd. v. Lotus Dev. Corp., 81 F.3d 1576, 1581, 38 USPQ2d              
          1665, 1669 (Fed. Cir. 1996).  In the present case, we note                  
          that the                                                                    
          court in Molins PLC v. Textron, Inc., 48 F.3d at 1181, 33                   
          USPQ2d at 1829 stated:                                                      
                         Thus, the alleged conduct must not                           
                    amount merely to the improper performance                         
                    of, or omission of, an act one ought to                           
                    have performed.  Rather, clear and                                
                    convincing evidence must prove that an                            
                    applicant had the specific intent to                              
                    accomplish an act that the applicant ought                        
                    not to have performed, viz., misleading or                        
                    deceiving the PTO.  In a case involving                           
                    nondisclosure of information, clear and                           
                    convincing evidence must show that the                            
                    applicant made a deliberate decision to                           
                    withhold a known material reference.                              


               We have determined that the Junior party has failed to                 
          establish that the invention was communicated to Larry Blake                


                                          28
