Advance China IP Law Office

Advance China IP Law Office (ACIP) was founded in 1999 by leading Chinese IP law practitioners who wanted to build a firm that would be honest, efficient, professional and enterprising. Over 20 years later, ACIP has become one of the largest full-service IP law firm in China, with nearly 900 IP professionals helping clients from all over the globe to obtain and protect their IP rights in China and other countries.

ACIP’s professionals have kept their promise to clients:

  • to be a one-stop IP consultancy for the prosecution, litigation and enforcement of their IP rights by competent attorneys who are highly experienced in local practice;
  • to provide responsive communication and reliable solutions to their urgent problems;
  • to be flexible and creative when devising and providing customised services that are the most cost/time-effective to clients; and
  • to offer consistent and transparent quotations and billing.

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 2019 some 414 patent attorneys and patent engineers specialised in technical fields of three primary technical groups (electrical/electronics and software – 216 professionals; mechanical engineering – 126 professionals; and life sciences and chemistry – 72 professionals) filed over 9,000 domestic patent applications, over 1,500 Patent Cooperation Treaty applications before CNIPA (the Chinese Patent Office), and over 4,000 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, who also frequently provide technology analysis, patent mining and training to clients.

ACIP has also built a team of 45 litigators since 2007, assisted by a group of 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 CNIPA and local IP offices. With an experienced in-house investigation team, ACIP attorneys have helped numerous clients conduct pre-filing investigation and administrative action 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, licence negotiation, patent assignment, filing or responding to request of patent invalidation, administrative petitions, initiating lawsuits and actions against unfair competition.

ACIP especially specialises in:

  • patent prosecution, such as patent drafting and prosecution; 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 right protection.


ACIP has been listed in the IAM Patent 1000 2019; in Tier 1 for Patent Prosecution and Contentious in China Southern Region by MIP from 2014 through 2017; among the Top 10 Best Chinese IP Firms for Patent Prosecution by IPR Daily in 2017; as the Outstanding IP Service Team of China by China Intellectual Property Magazine; and as China Four-Star Patent Agency by China Intellectual Property News in 2016.


ACIP’s attorneys also actively contribute to local IP associations and international conferences, serving for example as vice president of the All-China Patent Attorney Association and as members of the China Intellectual Property Society; the International Association for the Protection of Intellectual Property; the International Federation of Intellectual Property Attorneys; the Intellectual Property Owners Association; and the American Intellectual Property Law Association.
