We are at the leading edge of litigations. Each year, our one hundred or so IP litigators litigate hundreds of cases, accumulating abundant experiences with the dynamic practices of courts across China. We are at the forefront of frequently litigated issues, such as procedure, jurisdiction, enforcement, evidence admission, burden of proof, and interim reliefs. We litigate both civil and administrative cases before administrative agencies and at all levels of courts, with a concentration in more developed areas, such as Beijing, Shanghai, Guangdong, Shenzhen, Jiangsu, and Zhejiang. Our experience also extends to litigating criminal trade secret cases and arbitration matters.
Many of our cases are recognized as ground-breaking, not only creatively protect the interests of our clients but also help advancing the IP legal frontier. We have 30+ cases reported in the Supreme People's Court ("SPC") Gazette or selected by SPC for its annual 10/50 exemplary cases. Some of our cases involve parallel litigations in China as well as in other jurisdictions.
