Celine Liu

Celine Liu is Senior Counsel in the Washington, D.C. office of Wilson Sonsini Goodrich & Rosati, where she focuses on intellectual property litigation and counseling. She has experience litigating patent, trade secret, and licensing disputes in federal district courts, state courts, and before the U.S. International Trade Commission (ITC), having been involved in over 30 cases.

Ms. Liu's practice spans a broad range of technologies, including semiconductor technologies, mobile communications devices, wireless network communications products, LED lighting products, consumer electronics, computer cooling products, pharmaceuticals, and rare-earth products. Her tracked cases involve natural language processing patents, such as those related to virtual assistant technologies used by companies like Apple and Amazon. While her tracked appearances are exclusively on the plaintiff side, her firm profile indicates her involvement in both plaintiff and defense matters.

She was part of the Wilson Sonsini team that represented VB Assets, LLC in VB Assets, LLC v. Amazon.com, Inc. et al., which resulted in a jury ordering Amazon to pay $46.7 million for willfully infringing four patents related to its Alexa and Echo voice technologies. Ongoing royalty rates were also set in that case. Ms. Liu was also a member of the team that secured a complete defense verdict for Google in ReactX LLC v. Google LLC, a case alleging misuse of advertising technology. Additionally, she was part of the trial team that secured a jury victory for Epistar in a patent damages trial against Lowe's Home Centers, LLC, concerning LED filament bulbs.

While her firm, Wilson Sonsini, handles inter partes review (IPR) and post-grant review (PGR) proceedings before the Patent Trial and Appeal Board (PTAB) and ITC proceedings, Ms. Liu's individual firm profile notes her experience in "administrative proceedings" without specifically detailing her direct involvement in IPR/PGR proceedings in the U.S. She earned her J.D. from the University of Maryland Francis King Carey School of Law, an M.A. in Economics from Duke University, and a B.S. in Industrial Engineering and Management from National Chiao Tung University. She is admitted to the Bar of the District of Columbia.
