United States Supreme Court
The Lanham Act's prohibition on registering "immoral or scandalous" trademarks is an unconstitutional viewpoint-based restriction on speech.
Iancu v. Brunetti extended Matal v. Tam to strike down the Lanham Act's bar on registering immoral or scandalous marks, holding that any trademark refusal based on the perceived vulgarity or offensiveness of a mark's message constitutes viewpoint discrimination.
