How to check trademarks:

Many companies and individuals want to check whether their trademarks have been registered, or check their previously registered trademark information. However, due to unprofessionalism, they cannot do so online. The information found is very inaccurate. In fact, there are several ways to query trademarks:

1. Entrust the State Trademark Administration to pay for the query.

2. Entrust a trademark law firm (trademark agency) to inquire, most of which are free of charge.

3. Log in to the national trademark query system to query.
