Whether a trademark can be reneged upon a notarized transfer depends on the circumstances. One is: If you only issue a notarized certificate of trademark transfer and do not submit a trademark transfer application, it can be regarded as that you have not applied for trademark transfer, so you have no regrets. The second is: if a transfer application has been submitted to the Trademark Office, it cannot be withdrawn unilaterally, but an application to cancel the transfer can be submitted to the Trademark Office with the consent of the transferee.
