If the enterprise is required to produce proof (judicial or administrative determination) and the administrative determination, the State Trademark Office can inquire about the administration.

If the enterprise is required to produce legal documents, it can go to the court to search the criminal record. In case of forged documents!

Tongzhou Industrial and Commercial Bureau conducted an investigation on eight enterprises with well-known trademarks in its jurisdiction according to reports from the masses. After collecting legal documents such as judgments and conciliation statements issued by municipal intermediate people's courts and prefecture-level people's courts where the relevant provincial people's governments are located, it sent a letter to verify them in time, and its answers were all forged.

at the same time, you can send a letter to the Supreme People's Court to prove whether it is a well-known trademark that has been judicially recognized (all of them have been put on record). (If you send a letter to the petition office in the Supreme People's Court, there must be a definite reply.)

Don't think that China Well-known Trademark Network is real. Is there an official website? Those websites are all fake official websites by private individuals or agencies, and some people fool the people. In fact, there is no official website at all. Only the website of the court or the website of the State Trademark Office is official.
