Trademark transfer needs to go through the formalities in the Trademark Office, and its process includes: applying for accepting the review announcement and issuing the transfer certificate. The seller and the buyer sign a trademark transfer contract/agreement. Trademark notarization is generally completed within 3-5 working days after the trademark holder obtains the Trademark Declaration Notary Certificate. Submit the prepared materials and notarial certificate to the Trademark Office, and then pay the transfer fee (generally 1000 yuan). The Trademark Office issued an acceptance letter in about 1-2 months and began to review. The Trademark Office will issue an announcement about 5-8 months after accepting the application, and issue a certificate of approval and transfer of the registered trademark to both parties.
