Anti-Suit Injunction Issued in China: Comity, Pragmatism and Rule of Law

1 Anti-suit Injunctions issued in Huawei v Conversant and Xiaomi v Intel Digital

Chinese courts have issued two anti-suit injunctions recently in cross-border patent cases. The first is the Supreme Court’s ruling in Huawei v Conversant, (2019) Zui Gao Fa Zhi Min Zhong 732, 733 and 734 No 1. (here) Huawei, a Chinese telecom giant brought an action on 25 Jan 2018 in Jiangsu Nanjing Intermediate Court requiring determination of FRAND royalty for all Chinese patents held by Conversant that is essential to 2G, 3G and 4G standard (standard essential patent or ‘SEP’). Conversant brought another action in Düsseldorf, Germany on 20 April 2018 claiming Huawei infringed its German patents of the same patent family. On 16 Sept 2019, the Chinese court ordered a relatively low rate pursuant to Chinese standard and Conversant appealed to the Supreme Court on 18 Nov 2019. On 27 Aug 2020, the German Court held Huawei liable and approved the FRAND fee proposed by Conversant, which is 18.3 times of the rate determined by the Chinese court. Pursuant to Huawei’s application, the Chinese Supreme Court restrained Conversant from applying the German court to enforce the German judgment. The reasons include: the enforcement of the Düsseldorf judgment would have a negative impact on the case pending in Chinese court; an injunction is necessary to prevent irreparable harm to Huawei; the damage to Conversant by granting the injunction is significantly smaller than the damage to Huawei if not granting injunction; injunction will not harm public interest or international comity.
