There are two situations of secondary authorization:

Re-authorization of a trademark with explicit written authorization is valid and legal; unless there is explicit written authorization, secondary authorization is not allowed.

Secondary authorization is not allowed unless expressly authorized in writing.

First of all, to authorize a trademark, you need to sign a trademark authorization use agreement and explain the cost and period of use to avoid disputes later. Of course, it is not necessary to set a use period, but the trademark itself has a use period, and when the above use period expires, the authorized period will also expire.

The Trademark Law stipulates that trademark license contracts must be reported to the Trademark Office for filing. A trademark registrant can license others to use its registered trademark by signing a trademark license contract. A copy of the contract shall be submitted by the licensor to the Trademark Office for filing within three months from the date of signing the trademark license contract. The licensor shall supervise the quality of the goods used by the licensee using its registered trademark. The licensee shall ensure the quality of its products using the registered trademark. The licensee must indicate the name of the licensee and the origin of the goods on the goods using the registered trademark.
