China Patent Agent

What China Patent Agent does

China Patent Agent (H.K.) Ltd. (CPA) is a Hong Kong-headquartered intellectual property agency founded in 1984, operating as one of the three earliest-established IP firms in China. The firm delivers comprehensive IP legal services spanning patent prosecution (Chinese, PCT, and foreign applications), patent reexamination and invalidation, trademark registration and enforcement, copyright and software protection, trade secrets, unfair competition, licensing, assignment, mediation, and consulting. CPA serves both foreign multinational corporations seeking IP protection in China and Chinese enterprises pursuing overseas registration, operating a global office network across Hong Kong (HQ), Beijing, Shenzhen, Shanghai, New York, Tokyo, and Munich.

The firm's professional bench comprises approximately 230 patent attorneys, 40 trademark attorneys, and 20 litigators supported by total headcount of around 550 staff. CPA is organized around three practice pillars—Patents, Trademarks, and Legal Affairs—with technical specialization across 18+ domains including pharmaceuticals, biotechnology, semiconductors, AI, clean energy, automotive, chemicals, and telecommunications. The firm operates under an integrated "Beijing-Hong Kong twin-engine model" combining mainland China execution with offshore coordination for cross-border mandates. As of February 2025, CPA had accumulated approximately 230,000 invention patent grants, the only firm in China exceeding 200,000 grants.

CPA generates revenue through professional services fees tied to specific matters, with pricing determined per engagement rather than through disclosed subscription or productized models. Distribution is direct-to-enterprise via dedicated client teams and seven offices, with demand generation primarily driven by sustained recognition across major international IP directories (MIP, IAM Patent 1000, Chambers, Legal 500, WTR 1000, Asia IP, ALB) for over a decade, supplemented by industry conference participation, academic partnerships (notably a Peking University Law School scholarship program established in 2011), and professional publications.
