Understanding Interference Proceedings (Trademark) in Trademark Law

Definition & Meaning

Interference proceedings in trademark law are legal actions initiated before the Trademark Trial and Appeal Board (TTAB) to resolve disputes over the priority of trademark use. These proceedings are rarely used and are reserved for exceptional cases where the issue of who used a trademark first cannot be effectively addressed through more common methods, such as opposition or cancellation proceedings. The Commissioner of Patents and Trademarks declares these proceedings upon receiving a petition. The primary focus is to determine which party has the rightful claim to a trademark based on their first use.
