Opposition Sustained: Sun Bum LLC v. Rum Bum Tanning Co.
Summary
The USPTO Trademark Trial and Appeal Board sustained Opposition No. 91303585, ruling in favor of Sun Bum LLC and preventing registration of the trademark RUM BUM TANNING CO by defendant Daniel Miller. The opposition was filed on December 8, 2025, and decided on April 22, 2026. The decision prevents the defendant from obtaining federal trademark registration for the contested mark.
Trademark applicants and their counsel should conduct comprehensive likelihood-of-confusion analyses before filing applications. The sustained opposition demonstrates that TTAB will scrutinize marks with phonetic and conceptual similarity, particularly in overlapping commercial contexts (sun care products and tanning services).
