District Court Concludes that U.S. Patent Infringement Claim Can Be Brought With Respect to Installation of Allegedly Infringing Equipment on U.S.-Flagged Ship in Brazilian Waters

The World in U.S. Courts: Spring 2016 - Intellectual Property: Patent

M-I Drilling Fluids UK Ltd. v. Dynamic Air Ltda., U.S. District Court for the District of Minnesota, March 1, 2016

Plaintiff M-I is a UK corporation engaged in the business of developing and installing systems on ships to assist in the removal of waste created by the undersea drilling of oil wells. M-I and the defendant Dynamic Air, a Brazilian corporation, responded to a request for proposals for the installation of such systems issued by the Brazilian state-owned oil company, Petrobas. Dynamic Air won the bid and, at the direction of Petrobas, installed systems on seven ships, three of which were U.S.-flagged. M-I sued Dynamic Air in U.S. District Court in Minnesota (where Dynamic Air's corporate parent is located), claiming that the installation of Dynamic Air's systems on the three U.S.-flagged ships anchored in Brazilian waters infringed U.S. patents held by M-I.

Among the issues addressed by the Court was the applicability of U.S. patent laws to actions taken on U.S.-flagged ships outside U.S. territorial waters. Applying a ruling from a related case, the Court held that under the "Law of the Flag" the ships were U.S. territory, and so a U.S. patent infringement claim could be brought based on the installation of the systems.
