Firm overview

“Wanhuida Intellectual Property” is a service mark shared by Wanhuida IP Agency and Wanhuida Law Firm. It emblemizes the home of some 500 dedicated professionals, including trademark attorneys, patent attorneys, attorneys-at-law and their proficient staff and the high quality of services they provide for thousands of our clients worldwide.

Wanhuida is now home for some 500 employees working exclusively in the field of intellectual property. It has some 120 IP lawyers specialized in IP litigation and enforcement work, 160 trademark attorneys, 80 patent attorneys and 80 other professionals, including investigators and supporting staff. Many of them are recognized leaders in their respective fields. They have a wide range of experiences from private practice, in-house counselling, to government services in courts, police departments and administrative agencies.

The firm’s professionals have broad and in-depth experience. Over the years, they have accumulatively litigated over thousands of IP cases in courts all over China, prosecuted tens of thousands of patent applications, and filed hundreds of thousands of trademark registrations. Many of the cases are first of its kind. They are recognized by industries, courts and administrative agencies as exemplary cases for their legal significance.

Wanhuida understands the law and its context through years of study and practice. It also actively participates in the policy process for the development of laws. Since its creation, the firm has been closely associated with the legislative progress of Chinese IP laws and regulations. It continues to play an active role in the improvement of the Chinese legal and regulatory environment. Its practitioners are involved in the processes for revising the trademark law, patent law, copyright law, anti-unfair competition law, and relevant judicial interpretations through submission of comments to draft laws and organizing platforms for discussion and communicating with authorities responsible for policy development.

The firm’s active involvement in policy and law developments gives it good sense on the direction of the laws and equips its professionals with insights that can be critical for protecting the interests of its clients. It also has the pulse on the application of the law in context through thousands of cases before courts and administrative agencies.

This mix of legal expertise and result-oriented practical approach has been critical to the firm’s past success and is the constant among the dynamic changes it will keep as it launches into the future.
