Defense of Laches in Trademark Law and Legal Definition

In trademark, defense of laches is based upon plaintiff's inexcusable delay in asserting or attempting to enforce trademark rights. This doctrine is based on the theory that equity rewards the vigilant and not those who slumber on their rights. Failure to assert one’s rights in a timely manner can result in a claim's being barred by laches. Laches is a form of estoppel for delay.
