IP litigation and enforcement

ZY Partners has a prominent IP litigation practice – a result of its lawyers’ remarkable track record over the past two decades. The firm is committed to serving the best interests of its clients through consistently workable solutions and out-of-the-box ideas and strategies.

The firm has recognised experience in conducting IP trials and appellate work in the areas of patents, copyright, trademarks, unfair competition and trade secrets. All of ZY Partners’ partners are experienced IP litigators who, having been a part of China’s IP circle for nearly 21 years, still vigorously litigate in Chinese courts nationwide to protect clients’ interests – often in complex situations. Many of the firm’s partners, lawyers and paralegals have experience in the courts or the State Intellectual Property Office (now the China National Intellectual Property Administration). Their familiarity with court procedures and judicial perspective has greatly helped with case strategising and preparation, and ensured the efficiency of their advocacy at court hearings.

The firm’s litigation team has unparalleled experience and unique abilities in handling complex IP litigation and technology-related matters in China. Many of their cases have been published as guiding precedents by the Supreme People’s Court, the Beijing High Court and courts in other parts of China.

The firm has notable trademark litigation practice. Each year the trademark team handles more than 100 cases before courts in Beijing, Shanghai and across China. It has successfully obtained favourable recognition or clarification on critical issues in trademark practice from the Supreme People’s Court and courts in Beijing.

ZY Partners has rich experience in representing clients and protecting their trade secrets against former employees’ unfair competition acts; the firm also helps clients with anti-counterfeiting enforcement through customs border protection, criminal prosecution and administrative and civil actions.
