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
examiner. As a consequence of our review, we find ourselves in a
agreement with the examiner’s determination that the claimed
invention would have been obvious, within the meaning of 35
U.S.C. § 103(a), based on the applied references’ teachings. Our
reasoning follows.
