If the trademark is applied in the name of a company, the owner is the company. If the whole company is transferred to the other party, then the company already belongs to the other party, and the natural trademark belongs to the other party. If the company name changes, the address change agreement will contact the trademark agent to change. If only the legal person or shareholder changes, there is no need to change the trademark information. The change of a trademark refers to the change of the registrant, registered address or other matters of a registered trademark. Where the applicant changes its name, address, agent or deletes the designated trademark, it may go through the formalities of change with the Trademark Office. If you want to change the words and graphics of a registered trademark, you should re-apply for trademark registration and treat it as a newly applied trademark. It cannot be a trademark change. The materials to be provided for the transfer of the registered trademark of the company are as follows: 1. A copy of the trademark registration certificate; 2. Copy of the business license valid for the transferor's annual inspection and 2 copies of the official seal. 3. Copy of the transferee's subject qualification (if it is an individual: provide a copy of the ID card and a self-employed license; If it is provided by the company: a copy of the business license valid for annual inspection with official seal); 4.
