Testimonials

2025

"One of the top-notch firms."

"They are very responsive, communicative, and are reasonably priced."

Linked Reviews
Patent

Case studies show the firm, representing patentee KPN, successfully defended a standard-essential patent through multiple invalidation challenges and subsequent administrative litigation, ultimately persuading the Intellectual Property Court of the Supreme People's Court to uphold the patent's validity. Clients include Alfdex and Nihon Nohyaku. 

Trade mark

Case studies show the firm successfully represented the client in an administrative lawsuit before the Beijing Intellectual Property Court, persuading the court to overturn the CNIPA's rejection and rule that the applied-for mark is registrable, as its distinctiveness should be assessed based on the overall impression of the mark rather than a mechanical dissection of its components.
