M-I Drilling Fluids UK Ltd. v. Dynamic Air Ltda., No. 16-1772 (Fed. Cir. May 14, 2018)

From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

M-I Drilling Fluids U.K. Ltd. and M -I LLC sued D y- namic Air Ltda. in the U.S. District Court for the District of Minnesota, alleging infrin gement of five U.S. patents. The district court dismissed the case for lack of personal jurisdiction. Because Rule 4(k)(2) of the Federal Rules of Civil Procedure supports the exercise of specific personal jurisdiction over Dynamic Air Ltda., we reverse and remand for further proceedings.
