ZY Partners

ZY Partners is a boutique law firm with more than 20 years of expertise, providing the full range of IP legal services to major multinational corporations, growing enterprises, high-tech companies and other innovative clients. The key partners of the firm have excellent credentials and are well recognised for delivering a top-quality service to clients. The firm has a team of more than 40 experienced lawyers and patent attorneys representing innovation-oriented multinational corporate clients in cross-border transactional, non-contentious and contentious matters.

IP litigation and prosecution

ZY Partners has a prominent IP litigation practice – a result of our lawyers’ remarkable track record over the past decade. We have secured our clients’ trust by successfully protecting and enhancing the value of their IP rights in various jurisdictions in China, and have litigated rigorously to protect our clients’ interests, often in complicated situations. A number of the cases that we have handled have been published as guiding precedents by the Supreme People’s Court and local courts.

ZY Partners has been nominated as a leading IP firm in China by Managing Intellectual Property, Chambers Asia Pacific, the IAM Patent 1000, the WTR 1000 and Client Choice since 2009, based purely on its solid track record.

The industries in which we have the most patent-related legal and practical experience include pharmaceuticals, telecommunications, electronics and chemistry. We have rich experience in representing multinational clients in patent prosecution, invalidation and enforcement actions before the Patent Office, the Patent Re-examination Board, courts and local IP offices.

ZY Partners also manages trademark portfolios for multinational clients in a variety of industries, including apparel, fashion, cosmetics, pharmaceuticals, telecommunications, electronics, machinery, education, automotive and food and beverages. We regularly represent our clients in trademark oppositions and appeals at the Trademark Office and the Trademark Review and Adjudication Board, as well as related judicial reviews in courts.


Our attorneys frequently work with multinational companies and law firms in the United States and Europe on antitrust filings with the Ministry of Commerce. We have advised on antitrust issues in connection with patent pools, industrial standards and distribution arrangements in multinational business concentration transactions.

We have defended the rights of multinational clients in antitrust private litigations in China. Such litigations involve standard-essential patents in the telecommunications area and reservation of single digits and letters for domain name registration.

Employment and regulatory

ZY Partners’ team includes lawyers experienced in the area of employment. In particular, our attorneys with regulatory administrative backgrounds in government authorities provide valuable insight when delivering strategic plans to enforce clients’ IP interests in China.


Our attorneys are frequently asked to advise on cross-border licensing in the areas of telecommunications and electronics. We have special expertise to advise our clients on how to resolve technical and commercial complexities in the Chinese business context. In addition, the experience of our attorneys in standard formation and antitrust-related standard regulations and IP policies has proved particularly valuable to our clients.


Our attorneys are active in legislative consulting and administrative lobbying to enhance the government’s perception of the significance of respecting and securing the interests of IP owners. Our partners have been substantially involved in drafting and commenting on China’s IP laws and regulations. Several of our attorneys are adjunct professors and lecturers at prestigious law schools in China. In addition, our attorneys are closely engaged in lobbying activities through foreign chambers of commerce or industrial associations, which puts us in a unique position to serve our clients at every level.


Our lawyers are licensed to practise in China and have extensive experience in conducting litigations in all jurisdictions and at all levels of the Chinese courts. Most of the lawyers at ZY Partners have graduated from top law schools in China and many of them have degrees in science or engineering, such as computer technology, biotechnology and chemistry. Most of our lawyers are also fluent in English.

We emphasise team integration for our clients’ litigation projects, by carefully selecting core members of the team with the most appropriate level of experience to provide a quality service. The leading partners of the core team fully participate in strategising, implementing and representing clients before the courts, with direct and efficient interaction with associates.
