CCPIT Patent & Trademark Law Office

Firm overview:

CCPIT Patent & Trademark Office is among China’s foremost IP firms, known as a go-to choice for patent and trademark matters both within China and internationally. A peer agrees that CCPIT is one of “the top IP firms in China”. The firm has built on its heritage as China’s oldest full-service IP firm, growing alongside and contributing to the development of China’s patent system, to become a leader for non-contentious and contentious work.

The firm’s patents practice is widely acknowledged as top-tier, and offers a highly sophisticated prosecution service. An early frontrunner in representing foreign applicants in China, CCPIT is one of the few firms with a higher percentage of filings for international applicants than domestic. The firm is also recognised as a major player in patent enforcement and litigation.

Team overview:

President of the firm Chuanhong Long is a “leading and very senior” lawyer, a peer acknowledges. Long has been qualified as a patent attorney since 1996 and a lawyer since 1998. His practice has covered a broad range of patent matters, including prosecution, infringement and validity litigation, licensing, and portfolio management.

Patent attorney Juhua Luo is highlighted by a Japan-based multinational client as a go-to lawyer for patent prosecution. Luo’s practice encompasses all aspects of patent prosecution, as well as licensing, IP litigation and dispute resolution. Luo also “achieved great success” in patent defence and administrative litigations for the same client.
