Irreparable Harm - Injunctions can be an incredibly useful trademark enforcement tool, but they are difficult to obtain in many cases.  Since the U.S. Supreme Court's patent related decision regarding irreparable harm in eBay Inc. v. MercExchange, 547 U.S. 388 (2006), U.S., appellate courts have been divided on whether they extend that ruling to trademark cases. The TMA ends that division once and for all making it easier to get an injunction – a valuable tool!
