WAKU Opposition - Waku Inc. vs. Suntory Holdings Limited

Waku Inc. filed a trademark opposition proceeding before the USPTO TTAB challenging Suntory Holdings Limited's application to register the WAKU mark. The opposition, designated as proceeding number 91306383, was filed on April 6, 2026. This administrative proceeding initiates a formal challenge to the registrability of the WAKU mark under the Trademark Act.

For both parties, this TTAB opposition creates immediate litigation obligations and deadlines. Suntory Holdings must file an answer or risk default judgment, and both parties will engage in discovery and testimony periods typical of TTAB proceedings. The outcome may result in the WAKU mark being registered for Suntory or the opposition being sustained, blocking registration. Both entities should retain experienced trademark counsel to navigate this adversarial administrative proceeding.
