Court Declines to Dismiss Unclean Hands Defense

In a March 19, 2015 ruling, Judge Thomas P. Griesa declined to strike the defendant’s defense of unclean hands. Although the plaintiff is asserting a patent infringement claim, the unclean hands defense relates to the plaintiff’s alleged inequitable interference with the defendant’s supply agreement with a third party. The Court held that by “seeking an injunction against defendant [on the patent infringement claim], plaintiff comes to the court in equity” so the “defense of unclean hands deserves to be tried on the merits.”
