1. The content of the trademark violates legal provisions, for example, the trademark violates public order and good customs.

2. There is fraud or other improper means in the process of obtaining a trademark. A common method is to submit false subject information.

3. Copy or imitate well-known trademarks.

4. Maliciously register third-party trademarks. Some companies do not pay attention to their own trademark protection and do not apply for a full set of trademarks. They only discover that they have been registered when other types of trademarks are needed to develop new businesses. , this is the case with the previously uproarious case of Honor of Kings, which had its alcohol trademark registered by a winery.

5. Infringement of other people’s prior trademarks.
