                         A further explanation of why Deen's preliminary motions to substitute or add the                                         
                proposed count were denied appears within the decision. (Paper 62 at 13-24).                                                      
                                                        Dr. Chinnaivan's testimon                                                                 
                         As to Deen's second point, the decision addressed Dr. Chinnaiyan's cross-examination                                     
                testimony regarding TNFR death domains. The decision stated (Paper 62 at 18-19):                                                  
                                 Deen argues that we should not accept the testimony of Dr. Chinnaiyan.                                           
                         In particular, Deen argues that Dr. Chinnaiyan's declaration testimony is                                                
                         contradicted by Dr. Chirmaiyan's cross-examination testimony that... (FF 35)t'l:                                         

                                 (2) most TNFRs do not have death domains...                                                                      
                                 ...However ...  Dr. Chirmaiyan did not testify in his declaration that all                                        
                         TNFRs have death domains. Our understanding of Dr. Chinnaiyan's testimony                                                
                         is that it is necessary to characterize the intracellular domain to determine                                            
                         activity of a potential TNFR. Dr. Chinnaiyan's testimony indicates that it would                                         
                         be necessary to identify a death domain in order to characterize a TNFR as                                               
                         apoptosis inducing. Since no death domain is identified in the TR7 fragment, the                                         
                         fragment cannot be characterized as having apoptosis inducing activity.                                                  
                         Moreover, our determination that Deen did not sufficiently show that its provisional                                     
                application provided a constructive reduction to practice within the scope of either Count I or                                   


                         2 "IFF 35" refers to finding of fact 35 of the decision which reads:                                                     
                                 35. On cross-examination, Dr. Chinnaiyan testimony                                                               
                indicated, inter alia, that:                                                                                                      
                                          (1) Most TNFRs do not have death domains (Exh.                                                          
                                 2013 at 23), and                                                                                                 
                                          (2) even though there are exceptions (at least one                                                      
                                 where a TNFR has only one CRD[cysteine rich domain]), most                                                       
                                 TNFRs have multiple CRDs. Accordingly, the presence of                                                           
                                 multiple CRI)s increases one's confidence that a TNFR has been                                                   
                                 discovered. (Exh. 2001 at 37-50).                                                                                


                                                                         4
