Legal analysis: The regulations for the use of trademarks include:

1. The subject using the trademark must be legal

2. The trademark used must be legal

3. The name and scope of the goods or services using the trademark must be legal. The lack of any one of the requirements constitutes irregular use of the trademark.

Legal basis: Article 65 of the "Regulations on the Implementation of the Trademark Law of the People's Republic of China" Where a registered trademark stipulated in Article 49 of the Trademark Law becomes the common name of goods approved for use , any unit or individual may apply to the Trademark Office to cancel the registered trademark, and evidence materials must be attached when submitting the application. After accepting the application, the Trademark Office shall notify the trademark registrant. If the trademark registrant fails to respond within 2 months from the date of receipt of the notification, it shall not affect the decision of the Trademark Office.
