46.6 Case Problem with Sample Answer. Jan Voda, M.D., a resident of Oklahoma City, Oklahoma, owns three U.S. patents related to guiding catheters for use in interventional cardiology, as well as corresponding foreign patents issued by the European Patent Office, Canada, France, Germany, and Great Britain. Voda filed a suit in a federal district court against Cordis Corp., a U.S. firm, alleging infringement of the U.S. patents under U.S. patent law and of the corresponding foreign patents under the patent law of the various foreign countries. Cordis admitted, “[T]he XB catheters have been sold domestically and internationally since 1994. The XB catheters were manufactured in Miami Lakes, Florida, from 1993 to 2001 and have been manufactured in Juarez, Mexico, since 2001.” Cordis argued, however, that Voda could not assert infringement claims under foreign patent law because the court did not have jurisdiction over such claims. Which of the important international legal principles discussed in this chapter would be most likely to apply in this case? How should the court apply it? Explain. [Voda v. Cordis Corp., 476 F.3d 887 (Fed.Cir. 2007)]
