Silver - Firms: prosecution
Founded in 1986 as China’s first privately owned IP firm, Sanyou IP remains a go-to firm for technically demanding patent applications. Currently home to 160 scientifically adept patent attorneys, the outfit has a crack prosecution team tasked with steering critical drafting matters by both domestic and global industry leaders. One recent highlight includes the successful prosecution of a cutting-edge LCD technology on behalf of LG Display. Playing a significant part in this matter is agile portfolio manager and electronic expert Jiuliang Liu. Working alongside him is head of patent drafting team Haiping Tao, whose rich experience in patent filing allows her to undertake pedagogical tasks frequently as a Chinese IP law expert. Having handled over 1,000 patent applications and almost 100 invalidation cases over the past 13 years, general manager Xiaolin Dang’s proven success extends from drafting to re-examination, licensing and disputes.
