Silver - Firms: prosecution
“Beijing Sanyou is special to us because of the professional relationships and trust we have developed with their leadership team.” Partner, patent attorney and qualified lawyer Xiaolin Dang is foremost among Beijing Sanyou practitioners, having handled over 1,000 patent applications and almost 100 invalidation cases over the past 13 years. The 180 patent attorneys that make up the crack prosecution team are tasked with steering critical patent applications through the grant process by both foreign and domestic clients. One recent highlight was an important matter for LG Chem, where Beijing Sanyou representatives secured the revocation of an examiner’s rejection based on deep understanding of the underlying technology. “They provide strategic advice on substantive matters, professional quality correspondence, attention to detail, precision in billing and genuine care for the clients’ best interests,” expounds one foreign associate, adding: “The number of important patent cases our firm has entrusted to Beijing Sanyou has increased significantly.”
Founded in 1986, Beijing Sanyou Intellectual Property Agency Ltd was the first private IP firm in China.
