King & Wood Mallesons

King & Wood Mallesons (KWM) is an international law firm headquartered in China. We have more than 1,500 lawyers in 13 offices across China, and over 2,400 lawyers in 28 offices spanning China, the United States, Australia, Europe, the Middle East and Japan. We are a one-stop shop for legal services covering (among others) China, the United Kingdom, the United States, Australia, Japan, Germany and Italy. With a large legal talent pool equipped with in-depth local legal knowledge, we offer services in multiple languages.

Our IP practice, especially in patents, is uniquely positioned against this rich international backdrop. Our deep legal experience and technical expertise has helped us assist multinational and domestic clients with their IP needs. KWM’s high regard for clients’ intellectual property is the foundation of our business and our core value. We aim to provide the best possible 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 in the firm, our IP group provides the full gamut of IP services covering patents, trademarks, copyright, 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 artificial intelligence (AI), 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 consulting/strategy, searches/watch, patent application drafting and prosecutions. Together with the IP ligation team, we are highly experienced in patent re-examinations, patent invalidations, opinions on patent validity and non-infringement (freedom to operate), patent administrative lawsuits, civil actions and advice on strategies for patent protection.

KWM’s patent litigation team has an authoritative presence in the highly competitive Chinese market. We are well known for successfully representing leading and influential patent litigations in China and set new landmarks and 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 to combine technical competency and in-depth legal understanding. Almost all 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, AI and robotics.
