Rowe Price.

Taco Bell

Won dismissal of a class action alleging that Taco Bell overcharged customers for their Chalupa Cravings Boxes, which were advertised on television for $5 but cost $5.99 in some stores. We persuaded the court that while the ad's price disclaimer font was indeed smaller, it was “nevertheless clear and conspicuous.”


Won UDRP proceeding securing transfer of the Uniswap.com domain for the founder of the Uniswap protocol. In a novel case involving ownership of trademarks in the blockchain and DeFi space, the panel held that Uniswap had established trademark rights in the Uniswap trademarks, that the respondent’s registration and use of the Uniswap.com domain was confusingly similar to Uniswap’s trademark, and that the respondent’s registration and use of the domain was in bad faith.
