Bronze - Individuals: litigation

Among the first three pioneering prosecution shops in China, CPA’s Beijing-Hong Kong twin engine has been receiving effusive praise for its patent offering: “I am really impressed by their attention to detail, problem-solving mentality, excellent grasp of complex technical and patent issues and fabulous skills in presenting the complex legal and technical matters to the judge or re-examination panels in a concise and clear way.” Deputy general manager Shaohui Yuan anchors the 230-strong patent prosecution team with aplomb. Drawing on his valuable training in Germany, he is adept at machinery processing and auto engineering drafting. Working closely with him on the prosecution front are Songqing Zou and Chunyuan Liu. Previously a research and development engineer at China Aerospace Science and Technology Corporation, Zou is notable for his work in the mechanical engineering field. Germany-trained patent attorney Liu has recently succeeded in securing a re-examination decision on behalf of Continental Automotive before the CNIPA. Over in the litigation department, Yanfeng Xiong has unrivalled insight into standard essential patent (SEP) litigation and invalidation proceedings in the telecommunication field. He attracts rave reviews from his patrons: “Yanfeng is really one of the most devoted IP professionals I’ve worked ever with. He can delve very deep into the legal and technical matters of the case and then come up with practical and clear strategies which help to shape the course of the cases. He is considered the game changer in some cases. With this, he is definitely one of the best patent attorneys in China I would like to recommend.” Another enthusiastic patron would describe him as “one of the best patent attorneys on Chinese soil”. Yuhe Wu is another sterling litigator – he brings a background in biotech to bear on business-critical patent clashes. The pair is joined by litigators Chunlong Tang and Liang Wang. Several of Tang’s winning cases have been recognised by the Supreme People’s Court, the Beijing High Court and the Beijing IP Court as their annual top 10 cases; while China-New York dual-qualified Wang has routinely brought home the wins in court with high-stakes patent infringement litigation, patent invalidation and trade secret litigation matters.
