Cathy Lui concentrates on trade secrets litigation representing both plaintiffs and defendants in the biotech, retail and financial services industries. Cathy has a particular focus on obtaining and defending against temporary restraining orders and preliminary injunctions under exigent circumstances in fast-paced trade secret actions. 

Cathy has significant experience in actions arising from the Defend Trade Secrets Act (DTSA), which created the first federal civil misappropriation of trade secrets claim in May 2016.  Cathy has helped shape DTSA law on behalf of her clients through her involvement in some of the earliest DTSA litigation.  Many of her trade secrets cases involve parallel criminal proceedings. Cathy also engages in complex commercial litigation including breach of contract, fraud, and employee mobility cases. 

Cathy is an editor and contributing author of Orrick's trade secrets blog, Trade Secrets Watch, and regularly speaks and writes about trade secrets litigation.

Cathy is very involved in diversity and inclusion initiatives. She is co-chair of the Bay Area Asian American Bar Association Judiciary Committee and is also active in the California Minority Counsel Program, and the Firm's Asian American Affinity Group, hiring, and recruiting committees. Cathy's dedication to pro bono service was demonstrated by her work in an asylum merits hearing representing a Salvadoran religious activist persecuted by gangs in El Salvador. For her work on this matter, the Lawyers Committee for Civil Rights honored Cathy with the Father Cuchulain Moriarity Award. In addition, the Justice & Diversity Center of the Bar Association of San Francisco recognized Cathy as an Outstanding Volunteer in Public Service in 2014 through 2016 for her work with helping homeless clients remove outstanding warrants barring them from access to housing and employment.
