         Application No. 09/250,154                                                 


              REJECTIONS AT ISSUE                                                   
              Claims 4 through 6 stand rejected under 35 U.S.C. § 103 as            
         being unpatentable over Burns and Chase.  Claim 7 stands rejected          
         under 35 U.S.C. 103 as being unpatentable over Burns and Chase as          
         applied to claims 4 through 6 above, further in view of Takase.            
              Throughout the opinion, we make references to the Brief and           
         the Answer for the respective details thereof.1                            


                   OPINION                                                          
              With full consideration being given the subject matter on             
         appeal, the Examiner’s rejections and the arguments of Appellants          
         and the Examiner, for the reasons stated infra, we reverse the             
         Examiner’s rejection of claims 4 through 7 under 35 U.S.C. 103.            
              In rejecting claims under 35 U.S.C. § 103, the Examiner               
         bears the initial burden of establishing a prima facie case of             
         obviousness.  In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443,          
         1444 (Fed. Cir. 1992).  See also In re Piasecki, 745 F.2d 1468,            
         1472, 223 USPQ 785, 788 (Fed. Cir. 1984).  The Examiner can                


                                                                                   
         1 Appellants filed a Brief on July 30, 2002.  Appellants filed a           
         Reply Brief on December 24, 2002.  The Examiner mailed out an              
         office communication on January 8, 2003 stating that the Reply             
         Brief has been entered.                                                    
                                         4
