              Interference No. 103,272                                                                                       


              relevant time period were employees of General Electric Company.  The Heuschen record                          
              relies upon the following activities for actual reduction to practice.                                         
                             Dr. Heuschen, a Ph.D. polymer scientist, testified that on June 5, 1987, he                     
              issued a memorandum, HX 1, directing that a "campaign" be undertaken "fully identical" to                      
              ML 5468, except for using "p-cumyl phenol" endcap in place of "pt [paratertiary] butyl                         
              phenol" "to address the ductility issue of ML 5468."  ML 5468 is para-tertiary butyl phenol                    
              endcapped polycarbonate, having a low viscosity defined by Kasha Index as between                              
              2800 and 3400 centiseconds, measured at 250EC.  At that time, ML 5468 was being                                
              manufactured and marketed by General Electric for making compact (or audio) discs.  HR                         
              402 and 404 to 411.                                                                                            
                             Dr. Cooper, a Ph.D. organic chemist, testified that on July 10, 1987,                           
              pursuant to the memorandum (HX 1) he issued an order, HX 2, for the Lexan Resin Plant                          
              to produce and bag 5,280 pounds of polycarbonate resin powder endcapped with para-                             
              cumyl phenol and having a Kasha Index of 2800-3200 centiseconds at 250EC.  This                                
              production was identified as RL 5568 and Lot No. LN 7607; the run was done on July 10,                         
              1987.  HR 15 to 22.                                                                                            
                             Mr. Ungetheim testified that in July of 1987, he was the operations                             
              supervisor in the Lexan Resin Plant and that he was responsible for the supervision of the                     
              people who worked there and for the coordination and scheduling of the production of                           
              polycarbonate resins.  HR169 and 170.  Mr. Ungetheim testified that HX 8 consists of two                       


                                                               -11-
