OPINION
In reaching our decision in this appeal, we have given
careful consideration to the appellants' specification and
claims, to the applied prior art references, and to the
respective positions articulated by the appellants and the

not sustain the examiner's rejection of claims 1 to 5 under 35
U.S.C. § 103. Our reasoning for this determination follows.
