Leader Patent & Trademark Firm

Since its creation in 2001, Leader Patent & Trademark Firm (Leader IP) has been delivering premium IP services to domestic and international companies across the full spectrum of IP matters – including patent mining, patent drafting, patent filing and prosecution, IP analysis and strategy, patent validity action, IP litigation, negotiation and dispute resolution. The team is made up of more than 400 professionals with solid technical backgrounds in various technologies including communication, integrated circuit, automotive industry, machinery Industry, material and chemistry; some 95% of them hold a master’s or doctorate degree, a considerable proportion has overseas work/study experience, and some hail from abroad.

Patent drafting and prosecution

Leader IP has significant experience in representing foreign clients in patent filings and prosecution in China. The firm’s strengths lie not only in preparing high-quality applications and response to office actions, but also – drawing from a forward-thinking approach and up-to-date knowledge – in streamlining procedures, saving time and controlling costs effectively. The grant-rate of invention patent applications represented by Leader IP is far higher than the national average. Taking the statistics for 2020 as an example, Leader IP’s grant-rate is around 75%, while the national average is only around 40%. Similarly, the average rounds of office actions for a patent handled by Leader IP are lower than 1.6 and the average examination period is shorter than 18 months.

Such strengths also stem from the firm’ professionals extensive experience in drafting domestic and PCT patent applications in Chinese/English and handling patent applications abroad, as well as from the lessons learned from invalidation and litigation cases.

Taking advantage of its wealth of experience in drafting patents, its rich experience in handling outgoing cases, its in-depth mastery of scientific expertise and its thorough study of Chinese patent regulations, Leader IP offers unique and deep insights into the best way to secure high-quality patents in China for foreign clients. The team is fully aware of the differences between China’s patent-related regulations and those in other countries; it is also familiar with various problems encountered by and targets of foreign patent applications entering China and can therefore provide valuable comments on document amendments and the use of appropriate procedures to optimise patent documents, thereby helping foreign clients to improve the efficiency and quality of their patents in China under controlled time and cost.

Patent validity action and infringement litigation

Moreover, Leader IP’s patent invalidation and litigation team has rich experience before the China National Intellectual Property Administration (CNIPA) and courts. In a series of more than 20 patent invalidation cases petitioned by Apple against Qualcomm, Leader IP managed, on behalf of Qualcomm, to uphold the validity of a high number of patents at issue – at a much higher than CNIPA’s historical data for such proceedings. In addition, many invalidation cases represented by Leader IP have been listed in each year’s Top 10 Patent Invalidation Cases. For instance, among the 2018 Top 10 Patent Invalidation Cases announced by the CNIPA, two cases handled by Leader IP were ranked as joint number one. Leader IP successfully represented clients in several other leading and influential patent infringement litigations that were later selected as representative IP cases or typical cases by the Supreme People’s Court and/or the IP Courts, such as the series of patent disputes between Ericsson and Huawei and the series of SEP and non-SEP infringement litigations initiated by Nokia against Shanghai Huaqin. Thanks to its deep experience in patent-related disputes, Leader IP also provides outstanding prior art searches, patent searches, infringement analyses, freedom-to-operate analyses, and litigation and/or invalidation strategies.
