Our IP practice, especially patent practice, is uniquely situated under this rich international backdrop. We have provided services to multinational and domestic clients in profound legal experience and technical expertise. KWM’s high regard for clients’ intellectual property is the foundation of our business and our core practice. We aim to provide solutions to clients in their variety of IP-related issues. In that effort, we seek to break down old barriers and create new and innovative models to protect clients’ interests. We have been recognised as one of the leading IP practices in China by clients, peers and trade associations.

As one of the six large practice groups at the firm, our IP group provides full service in IP areas ranging from patents, trademarks and IP transactions to IP litigations. All the practices are spearheaded by 51 partners in different practice areas.

The patent prosecution team has more than 130 patent attorneys, patent agents and patent engineers covering all major technical fields including telecommunication, computer science, semiconductors, internet technology, electronics/electricity, pharmaceuticals, medical devices, biotechnology, chemicals, materials, automobiles, mechanicals and designs. The team provides our clients with high-quality patent searches/watch, patent application drafting and prosecutions. Our patent team is highly experienced in patent re-examinations, patent invalidations, opinions on patent validity and non-infringement, patent administrative lawsuits and advice on strategies for patent protection.

KWM’s patent litigation team has an authoritative presence in the highly competitive Chinese market. We have successfully represented many leading and influential patent litigations in China and set many new precedents. Many of our cases have been selected as annual representative IP cases by the Supreme People’s Court and other courts.

Our team has a wealth of experience in trial and appeal courts. Our winning recipe is the combination of technical competency and in-depth legal understanding. More than 85% of our patent attorneys have graduate degrees in technical areas and their ability in comparing patent claim features and targets can substantively aid our clients’ cases. Our colleagues with previous behind-the-bench experiences also add decent guides in focusing arguments to key issues. Our patent litigators have worked full time on patent infringement and invalidation cases for many years. We have developed special litigation capabilities and capacities in telecommunications, semiconductors, computer software, pharmaceutical and life sciences, artificial intelligence and robotics.
