Generally, the time for trademark transfer is 4 to 6 months.
if you submit the transfer application together with the transfer certificate, the transfer may be successful in about 4 months;
if only the application, power of attorney and business licenses of both parties are submitted for the first time, it may take longer. If the period involves correction, it is also possible to delay it to 8 months or even 1 year.
I hope the above information is helpful to you.
