Legal analysis: If a trademark agency needs to cancel its business registration, it should sign a termination agreement with the client for uncompleted agency matters or sign a sub-agency agreement with another person with its consent. After the trademark agency has completed the change procedures in accordance with the law, it should promptly go to the Trademark Office of the State Administration for Industry and Commerce to handle the relevant agency information change procedures. If the trademark agency fails to notify, it shall bear the legal consequences arising therefrom.
