          in view of the teaching of Miya, U.S. 4,931,417 (attached                   
          hereto as Appendix B), issued June 5, 1990, from Application                
          07/266,065, filed November 2, 1988 (Paper No. 52, p. 12, l. 7-              
          8).  After holding that “Miya . . . is prior art under 35                   
          U.S.C.  102(e)” (Paper No. 52, p. 9, last para.), the APJ                  
          found, inter alia (Paper No. 52, pp. 7-9):                                  
               44. Miya expressly describes a number of metallocene                   
                    compounds . . . some of which fall within the                     
          generic                                                                     
                    formula set out in Ewen 034's claims 1-3 and 5-8 and              
                    lack bilateral symmetry. . . .                                    
               . . . . .                                                              
               46. Miya discloses the use of an ionizing agent along                  
          with                                                                        
                    the metallocene compound, including                               
          methylaluminoxane,                                                          
                    in carrying out polymerizations. . . .                            
               47. Miya teaches that the compounds are useful as a                    
                    catalyst for “stereoregular-olefin polymerization.”               
                    Miya, col. 1, lines 10-12.                                        
               48. Miya’s Examples 7, 9, 15, 17, and 21 describe                      
                    polymerizations using metallocene compounds which                 
          lack                                                                        
                    bilateral symmetry and are covered by the general                 
                    formula of claims 1-3 and 5-7 of Ewen 034.                        
               49. Miya’s examples 7, 9, 15, 17 and 21 demonstrate                    
                    polymerizations which result in the formation of                  
                    isotactic polymers.                                               
               50. Miya does not describe the formation of                            
          hemiisotactic            polymers.                                          
               51. Because of the lack of description of hemiisotactic                
                                         14
