Bronze - Individuals: prosecution

For those who are in need of efficient filing, adept portfolio management and staunch defence of their patent rights in China, look no further than Linda Liu & Partners. Japanese clients have flocked to the Beijing partnership to assure sanctuary for their most important inventions at the CNIPA, but its reputation as the foremost safeguarder in the country flies further than the continent – it has recently assisted leading European tech giants in re-examining their critical invention patents. Seasoned litigator Sai Chen acquits herself with distinction in contentious disputes, which recently include a pair of big wins in design cases. Over at the prosecution unit, Tsinghua University PhD Junping Yan is a dab hand when it comes to materials science and inorganic chemistry, relishing the most complicated briefs. Having passed the U.S. Patent Bar in 2018, Nancy Song has been a key contact for the firm’s US clients and a redoubtable ally in IP strategy, portfolio management and technology transfer agreements. Another favourite of the international crowd is Peter (Baoyu) Zhang, who is equally comfortable getting stuck into a patent application and drafting an opinion for upcoming litigation. Turning his trained eye to all manner of biotech patent work, Wenhan Liu draws on subject-matter expertise and CNIPA experience to spell out how foreign companies can get better grants. Chuck (Chunqiao) WangHank (Xianhua) Shen and Yu Yan are among those making their debuts in the IAM Patent 1000 this year. Both Wang and Shen have excellent technical fluency and excel at both patent drafting and re-examination; Tokyo University chemistry PhD Yan has acted on high-profile invalidity cases throughout his career.
