If it is a counterfeit registered trademark of another person (the comparison between the two trademarks is almost the same), this infringement determination is issued by the trademark owner. Only registered trademark owners know whether the trademark is counterfeit (manufacturers usually have secret records), and they can identify the authenticity of the trademark under investigation.

If two trademarks are similar, ordinary consumers will be confused with a little attention. This kind of infringement can be determined by the industrial and commercial bureau according to law.
