United States Federal Circuit

In patent claims related to sub-sea wellheads, 1) the all-limitations rule will preclude appellant from arguing infringement under the doctrine of equivalents, 2) court erred in determining that a claim was invalid for lack of written description, and 3) written reports may qualify as "printed publications" under 35 U.S.C. section 102.
