Kai Trump Wins US Trademark Over 'Kai' Amid Opposition from UK Fashion Firm

Kai Trump trademark dispute Kai Collective USPTO ESPYs

Donald Trump's 19‑year‑old granddaughter, Kai Trump, filed a trademark application for the name “Kai” covering clothing, entertainment and education activities. The US Patent and Trademark Office accepted her filing on October 7, 2025, and later rejected a competing claim by the UK‑based fashion label Kai Collective, which had operated under the same name since 2021 and filed a Notice of Opposition claiming prior US sales.

Kai Collective argues it must prove continuous US sales over the past five years to block the trademark. Intellectual‑property attorney Josh Gerben noted the challenge could be significant if the UK firm can meet the proof requirement. Meanwhile, Kai Trump attracted additional public attention at the 2026 ESPYs in New York, where she appeared in a gold gown and prompted social‑media commentary comparing her looks to various Trump family members.

The trademark dispute underscores the complexities of cross‑border brand protection for emerging celebrity entrepreneurs.
