Appeal No. 2000-1101 Page 3
Application No. 08/702,325
Rather than reiterate the conflicting viewpoints advanced by the examiner and
the appellants regarding the above-noted rejection, we make reference to the answer
(Paper No. 17, mailed August 5, 1999) for the examiner's complete reasoning in
support of the rejection, and to the brief (Paper No. 16, filed April 19, 1999) and reply

the claims under appeal. Accordingly, we will not sustain the examiner's rejection of
claims 1 to 3, 5 to 17, 19, 29 and 30 under 35 U.S.C. § 103. Our reasoning for this

established by presenting evidence that would have led one of ordinary skill in the art to
