Appeal No. 96-1902 Application No. 08/156,679 We have carefully reviewed the appellants' invention as described in the specification, the appealed claims, the prior art applied by the examiner and the respective positions advanced by the appellants in the brief and reply brief, and by the examiner in the answer and supplemental answer. As a consequence of this review, we will sustain the rejections of claims 11-13, 15 and 16 under 35 U.S.C. § 103.

Considering first the rejection of claims 11-13, 15 and 16 under 35 U.S.C. § 112, first paragraph, we initially observe that the description requirement found in the first paragraph of 35 U.S.C. § 112 is separate from the enablement requirement of that provision.
