Yoiu can trademark a brand or product name. Or a figurative mark which is the legal name for a logo. As long as they are distinctive and not too similar to existing trademarks that are registered or widely used. Other things that can also be trademarked, though these are less common such as sound, pattern colours either singly or in combination, holograms, multimedia and motion. Smells have also been trademarked.
