The applicant sought an anti-suit injunction restraining the respondents from continuing a patent and contract dispute before a United States federal court in Illinois.
The respondents alleged that the applicant, as successor to a corporation that had entered a settlement agreement containing an Illinois forum selection clause, was bound by the agreement and had engaged in conduct infringing U.S. patents.
Applying the test in Amchem Products Inc. v. British Columbia (Workers’ Compensation Board), the court held the applicant failed to show that the foreign court assumed jurisdiction inconsistently with forum non conveniens principles or that substantial injustice would result if the foreign proceeding continued.
The Illinois court had jurisdictional connections including U.S. patents, Illinois governing law, and attornment by other defendants.
The application for an anti-suit injunction was dismissed.
