If we don't change the consequences.
Article 49 of the Trademark Law stipulates that if a trademark registrant changes the registered trademark, the registrant's name, address or other registered items during the use of the registered trademark, the local administrative department for industry and commerce shall order it to make corrections within a time limit; If it fails to make corrections within the time limit, its registered trademark shall be revoked by the Trademark Office.
In addition, the formalities for the subsequent exhibition of the trademark will not be handled, because the registrant of the trademark is the old company name, and the official seal of the original enterprise will be invalid after the company name is changed.
If the name of the enterprise on the new official seal is inconsistent with the name of the trademark registrant, the application for trademark renewal shall not be approved.
