In A. Bourjois & Co. v. Katzel, 260 U.S. 689, 43 S.Ct. 244, 67 L.Ed. 464 (1923), the Court held that a third party could not import a face powder manufactured in France when the plaintiff owned the United States trademarks for the product, even though the product sold was "the genuine product of the French concern...." Id. at 691, 43 S.Ct. at 245. The Supreme Court concluded that even an authentic foreign trademark on "genuine" merchandise may infringe a registered United States trademark.
