Fourth Circuit Clarifies Laches Standard for Trademark Litigation | Practical Law
On March 8, 2012, in Ray Communications, Inc. v. Clear Channel Communications, Inc., the Fourth Circuit clarified the elements of a laches defense to a trademark infringement action. The case is notable for the court's reasoning concerning when a trademark owner has sufficient knowledge of an infringement to require its pursuit of legal action and the types of proof required to show that a defendant suffered undue prejudice from the plaintiff's delay in bringing suit.
