                 Application No. 08/888,365                                                                                                             



                 argue on page 8 of the brief that the rejection of these claims                                                                        
                 should be reversed for the reasons expressed with respect to                                                                           
                 claims 1, 2, 4-7, 9-11 and 13-15.  However, claims 24 and 25 do                                                                        
                 not include the limitation that the cross-sectional shapes of                                                                          
                 the convex portion and the inner fins are asymmetrical.                                                                                
                 Therefore, appellants’ argument with respect to claims 24 and 25                                                                       
                 fails at the outset because it is predicated on limitations that                                                                       
                 do not appear in the claims.  See In re Self, 671 F.2d 1344,                                                                           
                 1348, 213 USPQ 1, 5 (CCPA 1982).  Since appellants have not                                                                            
                 presented any other arguments as to why the rejection of claims                                                                        
                 24 and 25 is improper, the rejection of claims 24 and 25 will be
