Jihong Lou is an associate in Quinn Emanuel’s Washington, DC office.  Her practice concentrates on patent litigation and appeal, with a particular emphasis on cases involving pharmaceuticals and biotechnology, including those arising under the Hatch-Waxman Act.  Jihong also represents clients in post-grant proceedings before the United States Patent and Trademark Office. 

Jihong has represented clients at all stages of patent litigation and appeal, from pre-litigation assessment, through claim construction, fact and expert discovery, to trial and appeal.  Drawing from her years of experience as a former Federal Circuit law clerk and a drug discovery project leader, Jihong applies her in-depth technical and legal experience in formulating case strategy, developing technical positions on infringement and invalidity, taking and defending depositions of fact and expert witnesses, preparing dispositive motions, and drafting key briefs.

Prior to law school, Jihong was a drug discovery project leader, group leader, and associate research fellow in medicinal chemistry at Pfizer, where she worked on drug discovery research projects in oncology, diabetes, ophthalmology, and virology therapeutic areas.  In 2008, she embarked on a career in law by attending law school in the evenings while working as a patent agent full time at a law firm.  From 2013 to 2017, Jihong served as a law clerk to the Honorable Alan D. Lourie on the United States Court of Appeals for the Federal Circuit.
