Legal analysis: trademark change mainly means changing the name and address, and an application for change needs to be submitted to the Trademark Office. Where a trademark registrant changes its name, it shall also submit a certificate of change issued by the relevant registration authority. If approved by the Trademark Office, a corresponding certificate shall be issued to the trademark registrant and announced; If it is not approved, it shall notify the applicant in writing and explain the reasons.

Where the name or address of a trademark registrant is changed, the trademark registrant shall change all its registered trademarks together; If it is not changed at the same time, the Trademark Office shall notify it to make corrections within a time limit; If it fails to make corrections within the time limit, it shall be deemed as abandoning the application for change, and the Trademark Office shall notify the applicant in writing.

Legal basis: Article 17 of the Regulations for the Implementation of the Trademark Law of People's Republic of China (PRC). Where an applicant changes its name, address, agent or addressee or deletes a designated commodity, it shall go through the formalities of change with the Trademark Office. Where an applicant transfers his trademark registration application, he shall go through the transfer formalities with the Trademark Office.
