Leader Patent & Trademark Firm

Leader Patent & Trademark Firm (Leader IP) has 19 years’ experience in dispensing excellent service to domestic and international companies across the full spectrum of IP matters. The professional team has 300 members with solid technical backgrounds in various technologies such as communication, integrated circuit, automotive industry, material and chemistry. A considerable proportion of our professionals have gained degrees abroad, including PhDs; some members are foreign nationals.

Leader IP’s strengths in representing foreign clients in patent filings and prosecution in China lie not only in preparing high-quality application documents and responses to office actions, but also in offering streamlined/time saving procedures and controlling costs effectively. The grant-rate of invention patent applications represented by Leader IP is far higher than the national average. For instance in 2019, Leader IP’s grant-rate was about 76% compared to the national average grant-rate of 44.3% (data from China National Intellectual Property Administration (CNIPA) official website). Meanwhile, the average rounds of office actions for a patent handled by Leader IP is below 1.8 and the average examination period is less than 22 months. Such strengths come from the long experience in drafting domestic and Patent Cooperation Treaty patent applications in Chinese/English and handling outgoing patent applications; these strengths also stem from the firm’s experience in invalidation/litigation cases. Taking advantage of drafting a large number of Chinese/English patents, the experience in handling outgoing cases, the in-depth mastery of scientific expertise and the thorough study of Chinese patent regulations, Leader IP has unique and deep insights into representing foreign companies to obtain high-quality patents. The team is highly aware of the differences between China’s patent-related regulations and those in other countries; familiarity with various problems and targets of foreign patent applications entering China helps the team make valuable amendment recommendations and use appropriate procedures to optimise the documents, thereby helping foreign clients to improve the efficiency and quality of their patents in China under controlled time and cost.

Moreover, Leader IP’s patent invalidation and litigation team has rich experience in patent invalidation proceedings and patent infringement actions. In a series of more than 20 patent invalidation cases petitioned by Apple against Qualcomm, Leader IP achieved on behalf of Qualcomm a ratio of maintaining patent that is significantly higher than CNIPA’s historical data. Many invalidation cases represented by Leader IP have been listed in each year’s Top 10 Patent Invalidation Cases chosen by the Patent Re-examination and Invalidation Board. For instance, two Leader IP’s cases were ranked as joint top one among the Top 10 Patent Invalidation Cases of 2018.

Leader IP also has a successful track record of representing clients in high-profile infringement litigations, with some cases selected as annual representative IP cases by the Supreme People’s Court and/or IP Courts, such as the series of patent infringement litigations between Qualcomm and Apple, the series of patent disputes between Ericsson and Huawei, and the series of standard essential patent and non-standard essential patent infringement litigations between Nokia and Shanghai Huaqin. This extensive experience in patent-related disputes means that Leader IP can also provide outstanding performance in prior art search, patent search, patent infringement analysis and freedom-to-operate analysis, among other things.

Fang Liu, the founder of Leader IP, has been engaged in intellectual property since 1995. She has received the highest honours for Chinese patent attorneys, being selected for instance among the “Top-Ten Influential People in National Intellectual Property System (Patent)” and “National Intellectual Property Leader”. Ms Liu channels over 25 years’ IP experience into truly impressive performances in the most complex cases and always offers the best IP solution for her clients, which include Huawei, Sony, Qualcomm and Siemens. In addition, she also acts as the technical investigator for the Chinese IP Courts and judicial technical experts.

Shuang Ma, who manages Leader IP’s international department and deals with complex and important cases for clients such as Qualcomm, Airbus, Hyundai MOBIS and DJI, provides comprehensive and intelligent advice for clients to obtain strong IP protection; she has an impressive track record of winning patent invalidation and litigation cases. She has been named “National Outstanding Patent Attorney” and employed as an expert for the national overseas IP protection platform.
