                      U.S.C.                                                                                                                                                                      
                      § 103 as being unpatentable over Tsuchino.                                                      2                                                                           

                                  Rather than reiterate the arguments of Appellants and the                                                                                                       

                      Examiner, reference is made to the brief, reply brief and                                                                                                                   

                      answer for the respective details thereof.                                                                                                                                  



                                                                                        OPINION3                                                                                                  

                                  After a careful review of the evidence before us, we                                                                                                            

                      will not sustain the rejection of claims 21, 22, 24, 25 and 27                                                                                                              

                      under 35 U.S.C. § 103.                                                                                                                                                      

                                  The Examiner has failed to set forth a prima facie case.                                                                                                        

                      It is the burden of the Examiner to establish why one having                                                                                                                

                      ordinary skill in the art would have been led to the claimed                                                                                                                



                                  2These rejections are stated as new grounds of rejection in the Answer,

                      time, the subject matter of these canceled claims was added to the respective

                                  3As a preliminary matter, Appellants had indicated in their brief that                                                                                          
                      the Board would be updated on any related appeals and interferences after a                                                                                                 
                      completion of reviewing their files. At oral hearing Appellants indicated that                                                                                              
                      no related appeals or interferences had been found.
