Using a trademark without authorization in business dealings is an infringement. Only when the licensee uses the licensed trademark within the period stipulated in the contract can it be deemed as authorized and legal behavior. If the licensee uses the licensed trademark beyond the contract period, it will be deemed as infringement unless there is a statutory reason. Article 58 of the "Trademark Law of the People's Republic of China" If someone uses another person's registered trademark as a trade name in a business name, misleading the public and constituting unfair competition, he shall be punished in accordance with the "Trademark Law of the People's Republic of China" Competition Act.
