Legal analysis: The question of "whether a registered trademark is legal or not" should be discussed according to different situations. "Trademark cybersquatting" includes malicious cybersquatting and non-malicious cybersquatting. The purpose of malicious cybersquatting is to harm others and benefit themselves, which is illegal; Non-malicious cybersquatting (such as "goodwill cybersquatting" similar to negotiorum gestio) does not aim at harming others and benefiting themselves. Malicious cybersquatting is legal.

Legal basis: Article 15 of the Trademark Law of People's Republic of China (PRC) applies for registration of a trademark of the same or similar goods that is identical or similar to the unregistered trademark previously used by others. If the applicant has a contract, business relationship or other relationship with the other party but knows that the other party's trademark exists, the other party will not register it.
