An unregistered trademark (or common law trademark) is a brand name, logo, or slogan used in commerce without formal government registration, but still protected under state-based common law, granting rights only in the geographic areas where it's actually used, unlike the nationwide protection of registered marks, and it's often indicated by the ™ symbol. These rights arise from use, not registration, meaning the first user gains exclusive rights in their territory, but proving infringement can be more difficult and remedies more limited than for federally registered marks.

An LLC protects personal assets from business liabilities (legal structure), while a trademark protects brand identity like names, logos, and slogans from copycats (intellectual property); they serve different roles, with an LLC forming the business foundation and a trademark safeguarding its brand, often used together for comprehensive business protection.
