The TTAB sustained Opposition No. TTAB91302696 in favor of Marvel Characters, Inc. against Bizzplug LLC, preventing registration of the VIBRANIUM ENERGY trademark. The opposition was filed on October 27, 2025, and the Board issued its sustaining decision on April 2, 2026. Marvel likely succeeded on likelihood of confusion grounds given the well-known VIBRANIUM mark associated with Black Panther/Wakanda in the Marvel Universe.

For trademark applicants and brand owners: Review pending applications for potential conflicts with famous third-party marks, particularly in entertainment and consumer goods sectors. Ensure trademark filings include proper clearance searches to avoid costly opposition proceedings. Legal counsel should monitor TTAB decisions for precedential guidance on likelihood-of-confusion analysis.
