Don’t wait too long to protect your trademark. Since the 1990s, Cosmetic Warriors Ltd. sells “Lush” brand personal products like soap, lotions and makeup. For a brief period, Cosmetic Warriors sold a small number of t-shirts. But for the most part, Cosmetic Warriors does not sell clothing. Pinkette Clothing, Inc. started selling clothing using the brand name “Lush” in 2003. In 2009, Pinkette applied to register the trademark and it was registered in 2010. Cosmetic Warriors didn’t contest the registration. Almost 5 years after the registration of Pinkette’s trademark, Cosmetic Warriors sued Pinkette for trademark infringement. Cosmetic Warriors said that it didn’t know about the registration to explain why it waited so long to bring suit. Cosmetic Warriors won the battle but not the war. A jury sided with Cosmetic Warriors on the infringement issue. But then the jury sided with Pinkette on Pinkette’s argument that Cosmetic Warriors was barred by laches because it waited too long to bring suit. The jury’s verdict was upheld on appeal.

WHY YOU SHOULD KNOW THIS. There are 3 important points to unpack here. First, Trademark Law allows the registrant of a trademark to have the mark deemed uncontestable 5 years after registration. Once it’s declared uncontestable, the registration can only be challenged on the limited grounds of a fraud in the application or abandonment. That brings us to the second important point. The court in this case held that this five year benchmark is not a statute of limitations. So a registrant who is defending a challenge can claim the laches defense; even if the challenge comes before the 5 year benchmark. That’s important because the U.S. Supreme Court has held in patent and copyright cases, that the laches defense is not available before the statute of limitations runs. Third, registration of a trademark is notice of the use of the trademark. So, Cosmetic Warrior couldn’t rely on its argument that it didn’t know about Pinkette’s trademark until it brought suit almost 5 years after Pinkette’s registration.
