This Connect provides a brief overview of the judgement of the High Court of Bombay in the Tiktok Limited case, wherein the Court upheld the refusal of the Registrar of Trade Marks to include ‘TikTok’ in the list of well-known marks. It held that a ban imposed on the app by the Government of India on national security grounds is a relevant fact that the Registrar can consider under the Trade Marks Act, 1999.
