1. What are the ways to change the owner of a trademark? There are two ways to apply for changing the trademark owner: 1. Entrust a nationally recognized trademark agency to handle the matter. 2. The applicant goes directly to the Trademark Registration Hall of the Trademark Office to apply. To change the trademark registrant, the following information should be submitted: 1. Application form for changing the name of trademark registration. 2. A certificate issued by the local Administration for Industry and Commerce or the competent department proving the change from "previously single lambda" to "currently single lambda". Note: If the registrant is an enterprise, a change certificate from the registration department of the industrial and commercial administration authority shall be issued; if the registrant is a public institution, a change certificate from the registration authority of the public institution shall be issued; if the registrant is a natural person, a change certificate from the police station where the household registration is located shall be issued prove. The name before the change and the name after the change on the certificate should be consistent with the name before the change and the name of the applicant on the application form. 3. If you have an agent, you must submit a trademark agency power of attorney. Submit the above documents to the Trademark Office. After approval, the Trademark Office will issue a change certificate and announce it; the registrant will continue to enjoy the trademark rights after completing the change procedures. When applying to change the name of the trademark registrant, we need to pay attention to the following issues: 1. All registered trademarks are changed at once. 2. If there are multiple changes, the procedures should be completed in sequence and cannot be completed in one step, such as A → B → C. 3. The power of attorney and application form for changing the name of the registrant are handled in the changed name. If the renewal is due, it can be processed together with the change. 4. One change application should be accompanied by one supporting document of the change, and several applications should be accompanied by several supporting documents. 5. The supporting documents must be consistent with the name of the registrant on the registration and cannot be simplified or expanded. 6. The change certificate cannot be replaced by a business license or an application for change of business license. 7. The change certificate must indicate who changed to whom or from what to what. 8. If two enterprises merge or one enterprise is separated into two enterprises, the procedures for transferring the registered trademark should be completed. 9. If the name of the registrant is changed together with the renewal of the certificate, the application for renewal of the certificate should be processed in the original name and not in the changed name. If the original stamp is invalid and handed in and the application cannot be stamped, the application form shall be submitted to the Industrial and Commercial Administration. The certificate issued by the Administration Bureau does not need to be stamped, because the name of the registrant has been changed and the certificate issued by the Industrial and Commercial Administration Bureau and the supplementary certificate are required. To sum up, if a trademark owner wants to sell or transfer his trademark as personal property to others, he must change the legally registered name. Otherwise, even if the trademark is actually owned by others in the future, if it is in At the legal level, only the trademark owner on the registration information is protected, not the actual owner.
