Work highlights
Represented Marriott in a 3-week trial against Delta Air Lines, which alleged thatMarriott’s acquisition of the brand DELTA HOTELS in 2015 infringed and diluted Delta AirLines’ DELTA mark.
Secured an ex parte temporary restraining order in California's Central District stopping defendant 7-Eleven stores from selling counterfeit LABUBU products, with the Court finding POP MART likely to prevail on the merits of its trademark and copyright claims.
Successfully defended OpenAI’s longstanding “OpenAI” trademark—winning a preliminary injunction, affirmance on appeal, and ultimately summary judgment—which halted a competitor’s use of the confusingly similar “Open AI” mark and resulted in cancellation of the competitor’s trademark.
