Appeal No. 1999-1873 Page 3
Application No. 08/762,572
Rather than reiterate the conflicting viewpoints advanced by the examiner and
the appellants regarding the above-noted rejection, we make reference to the final
rejection (Paper No. 8, mailed April 21, 1998) and the answer (Paper No. 18, mailed

and to the brief (Paper No. 16, filed November 30, 1998) for the appellants' arguments
