                    Appeal No.  1997-1307                                                                                                
                    Application No.  08/014,012                                                                                          

                            Where the examiner fails to establish a prima facie case, the rejection is                                   
                    improper and will be overturned.  In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596,                                    
                    1598 (Fed. Cir. 1988).  Accordingly, we reverse the examiner’s rejection of claims                                   
                    15-18 and 20-24 are rejected under 35 U.S.C. § 103 as being unpatentable over                                        
                    the combined teachings of Tsukagoshi, Weng and Hosaka, taken in view of                                              
                    Gennari, Nudler and SIGMA.                                                                                           

































                                                                   7
