1. If you use your own portrait to apply for a trademark, you must provide notarization of the identity of the portrait owner. The portrait rights holder must go to the notary office in person to have the declaration notarized, bringing along his ID card and household registration book.

2. If you apply for a trademark using a portrait other than your own, provide a notarized agreement authorizing the use of the portrait right holder. Combined with the interpretation of the "Trademark Trial Standards" on the trial of portrait right infringement cases, the use or registration of another person's portrait as a trademark without permission will not be accepted. If someone else registers their own characteristics as a trademark without authorization, the rights holder can file a lawsuit to claim his or her prior rights.
