Trademarks are an integral part of an LLC's identity. A trademark is a word, phrase, symbol, or design that identifies and distinguishes the source of a company's products or services from those of its competitors. Without a trademark, an LLC risks being confused with other businesses, losing customers, and losing the value of its brand. An LLC must register its trademark with the United States Patent and Trademark Office in order to protect it from infringement by other businesses. A trademark is essential for an LLC to protect its brand and identity, and to ensure its success.
