Trademark issues are frequently litigated in the United States Patent and Trademark Office, yet circuits were previously divided on how much weight to give those decisions. The Supreme Court provided the answer. B&B Hardware v. Hargis Indus. held that in certain circumstances, the Trademark Trial and Appeal Board will have a preclusive effect on federal district courts. This comment looks at what effect this ruling will have on trademark litigation in district courts by examining the cases that caused the circuit split leading up to the Supreme Court’s decision.
