hello, if the trademark registrant is an individual, the change of address of the registrant has little effect on the trademark. If the trademark registrant is owned by a company, the address of the trademark registrant registered by the Trademark Office must be changed accordingly. The information you need to provide for the registrant to change the address includes: 1. Application for changing the name/address of the trademark applicant/registrant; 2. Power of attorney for trademark change; 3. The copy of the changed company license is stamped with the official seal of the company; trade mark registration
