          Application 08/290,093                                                      


          examiner’s rejection.  Because no prima facie case of                       
          obviousness has been established, we need not address                       
          appellant’s evidence of commercial success.  See In re                      
          Piasecki, 745 F.2d 1468, 1472, 223 USPQ 785, 788 (Fed. Cir.                 
          1984); In re Rinehart, 531 F.2d 1048, 1052, 189 USPQ 143, 147               
          (CCPA 1976).

               The rejection of claims 10, 13-18 and 20 under 35 U.S.C.               
          § 103 over Parrotta in view of Sakai is reversed.                           
                                      REVERSED
