Patent team

ACIP is especially proud of its patent prosecution and litigation practice. The firm builds patent portfolios for clients from various industrial sectors with insights, quality and efficiency. In 2020 some 417 patent attorneys and patent engineers specialised in technical fields of three primary technical groups (electrical/electronics, informationa technology and software – 216 professionals; physics and mechanical engineering – 126 professionals; and life sciences and chemistry – 72 professionals) filed over 20,000 domestic applications for invention, utility model and design patents, over 1,200 Patent Cooperation Treaty applications before the China National Intellectual Property Administration (CNIPA, the Chinese Patent Office), and over 3,500 foreign-related applications.

Clients trust the firm’s patent attorneys to understand their technology, have comprehensive knowledge of patent-related and general laws and regulations, and plan commercial-oriented strategies. The attorneys’ fluency in numerous languages besides Chinese (eg, English, German, French, Japanese and Korean) ensures responsive and smooth communication with regard to both technical and legal aspects of their work. Patent drafting and prosecution are strictly supervised by senior patent attorneys that include former patent examiners and senior IP rights professionals who have previously worked in famous technology-based companies. Technology analysis, patent mining and training seminars are also frequently provided to clients.

ACIP has also built a team of 45 litigators since 2007, assisted by senior professionals including former re-examination board examiners and technical experts with abundant experience in patent litigation, invalidation and enforcement in the local courts and all the way to the Supreme Court, and before the CNIPA and local IP offices. With an experienced in-house investigation team, ACIP attorneys have helped numerous clients conduct pre-filing investigations and administrative actions to overcome the difficulty of evidence collection due to the absence of discovery in China. ACIP has also established a highly experienced team for patent invalidation in its Beijing office for quick action against attack or as defence in a dispute. In case of patent disputes, ACIP effectively helps its clients achieve their commercial goals by customising their strategies, using local investigation, licensing negotiation, patent assignment, filing or response to request of patent invalidation, administrative petitions, initiating lawsuits and actions against unfair competition.

ACIP specialises in the following, in particular:

  • patent prosecution, such as patent drafting and prosecution in China; patent registration in Hong Kong and Macau; patent re-examination and appeal; patent invalidation; patent search and analysis; and patent transactions and licensing; and
  • patent litigation and enforcement, such as investigation, notarisation and evidence collection; administrative enforcement; civil and criminal litigation against infringement and unfair competition; IP-related administrative litigation; and customs IP rights protection.
