In this article,two cases of Standard Essential Patents,ruled by the Supreme People's Court of the People's Republic of China,are presented and analyzed.The first Chinese anti-suit injunction in SEP litigation appeared in the first case through the method of behavior preservation,and the second case illustrates a clear intent by the Chinese courts to compete for global royalty rate jurisdiction.With international concerns raised about these cases,it is proved that the anti-suit injunction cases in China do not show any abusive or illegal conduct.The worldwide anti-suit injunctions in China are granted legitimately with legal jurisdiction over the cases,sufficient legal grounds for behavior preservation with the nature of anti-suit injunctions,the necessity of granting worldwide injunctions,and suitable granting standards.Several pieces of advice are proposed for the future application of anti-suit injunctions,including improvements in the predictability of validity scope,consistency of implementation,and clarification of penalties.
