Legal analysis: If you only issue a notarial certificate of trademark transfer and do not submit a trademark transfer application, it can be regarded as that the trademark transfer has not been carried out, so there is no regrets. If a transfer application has been submitted to the Trademark Office, it cannot be withdrawn unilaterally, but an application to cancel the transfer can be submitted to the Trademark Office with the consent of the transferee.

Legal basis: "Trademark Law of the People's Republic of China" Article 42: If a registered trademark is transferred, the transferor and the transferee shall sign a transfer agreement and submit the same request to the Trademark Office Make an application. The transferee shall ensure the quality of the goods using the registered trademark.
