If the trademark is applied for in the name of a company, the owner is the company. If the company is transferred as a whole to the other party, then the company already belongs to the other party, and naturally the trademark belongs to the other party. If the company name changes, please contact the trademark agent to change the address change agreement. If there is only a change of legal person or shareholder, there is no need to change the trademark information. Change of trademark refers to changing the registrant, registered address or other matters of a registered trademark. If an applicant changes his name, address, agent, or deletes a designated trademark, he may go through the change procedures with the Trademark Office. If you want to change the text or graphics of a registered trademark, you must resubmit a trademark registration application and it will be treated as a new trademark application and cannot be changed.
