The U.S. Patent and Trademark Office's Trademark Trial and Appeal Board (TTAB) has issued a decision sustaining an opposition (Docket No. TTAB91302966) filed by Volkswagen Aktiengesellschaft against the VWWUI trademark. The opposition was sustained on March 18, 2026, effectively preventing the registration of the VWWUI mark in favor of Volkswagen.

This decision means that the party attempting to register the VWWUI mark, Chan Man Yung, will not be able to proceed with its registration due to the successful opposition. Companies involved in trademark disputes should note this outcome as an example of TTAB proceedings and the potential for established brands to successfully challenge new mark applications. No specific compliance actions are required for other entities, but legal teams should be aware of the outcome for brand protection strategies.
