It is recommended that you find an agency to do it. The cost should not be very high, most of them are around 1500-1800. Because when transferring, the Trademark Office will check whether the official seal of the transferor has been changed and whether it is the official seal at the time of the earliest application. The handwriting of the signature must be checked to see whether it is the same as the one signed when the application was made. Whether the business license is valid for annual inspection and whether it is stamped with the official seal, etc. , so you’d better not do it yourself. If you don’t have one thing or another, the time and cost of making a few more trips are a little bit more than the agency fee. It’s best to find an agency with good business knowledge to do it.
