The TTAB issued a final decision sustaining opposition No. 91297936, wherein Monster Energy Company successfully opposed Shanghai Wanxiangheyi Cosmetics Co., Ltd.'s application to register the HERBEAST trademark. The Board's decision, dated March 31, 2026, blocks registration of the contested mark following Monster Energy's challenge based on likelihood of confusion or other statutory grounds for opposition.

Regulated entities, particularly those in the cosmetics, beverage, or consumer goods industries, should recognize that this decision prevents the defendant from registering or using the HERBEAST mark in U.S. commerce. Companies should review their own trademark portfolios for potential conflicts. Trademark opposition decisions are binding on the parties and difficult to appeal; any further challenge would require proceedings before the Federal Circuit.
