Recently, Intellectual Asset Management (IAM), the renowned intellectual property media platform under global legal media group Law Business Research, officially released its 2025 edition of the “IAM Patent 1000” rankings. Thanks to its continued dedication and outstanding performance in the patent field, Chang Tsi & Partners has once again been ranked among the top Chinese domestic firms for both Patent Litigation and Patent Prosecution.

In addition, partner Michael Wu was selected for both the Patent Litigation and Patent Prosecution individual rankings for Chinese lawyers. This double recognition highlights both his achievements and the firm’s broader capabilities in handling complex and high-stakes patent matters.

The IAM Patent 1000 is a globally authoritative guide published annually, covering key areas such as patent prosecution, litigation, transactions, and licensing. Based on extensive market research, client feedback, peer recommendations, and expert interviews, the guide identifies top-performing firms and individuals in each jurisdiction. It is widely regarded as one of the most influential rankings in the global patent legal services industry.
