2. The buyer and the seller sign the "Trademark Transfer Contract/Agreement". The trademark holder handles trademark notarization, which usually takes 3-5 working days to complete and obtain the "Trademark Declaration Notarization Certificate". Submit the prepared materials and notarial certificate to the Trademark Office, and then pay the transfer fee (usually 1,000 yuan).

3. The Trademark Office will issue the acceptance letter in about 1-2 months and start the review. The Trademark Office will publish an announcement about 5-8 months after accepting the application and issue a "Certificate of Approval of Transfer of Registered Trademark" to both parties.

Legal basis: "Trademark Law of the People's Republic of China" Article 18 When applying for trademark registration or handling other trademark matters, you can handle it yourself, or you can entrust a trademark agency established in accordance with the law to handle it.
