Legal analysis: Trademark invoicing types belong to 35 categories. Trademark is a sign used to identify and distinguish the source of goods or services. Any sign that can distinguish the goods of natural persons, legal persons or other organizations from the goods of others, including words, graphics, letters, numbers, three-dimensional signs, color combinations and sounds, and the combination of the above elements, can apply for registration as a trademark. A brand or a part of a brand is called a "trademark" after it is registered by the relevant government departments according to law. Trademarks are protected by law, and registrants have exclusive rights. Famous trademarks in the international market are often registered in many countries. There is a difference between "registered trademark" and "unregistered trademark" in China. A registered trademark is a trademark protected by law after being registered by the relevant government departments, while an unregistered trademark is not protected by trademark law.

legal basis: article 43 of the trademark law of the people's Republic of China, a trademark registrant may authorize others to use his registered trademark by signing a trademark license contract. The licensor shall supervise the quality of the goods in which the licensee uses its registered trademark. The licensee shall guarantee the quality of the goods using the registered trademark. Where a registered trademark of another person is used with permission, the name of the licensee and the place of origin of the goods must be marked on the goods using the registered trademark. Where another person is licensed to use his registered trademark, the licensor shall report his trademark license to the Trademark Office for the record and the Trademark Office shall make an announcement. A trademark license may not be used against a bona fide third party without filing.
