Chien (born September 10, 1973) is an Asian-American legal scholar who is a law professor at UC Berkeley School of Law, where she teaches, mentors students, and conducts cross-disciplinary research on innovation, intellectual property, and the criminal justice system, with a focus on how technology, data, and innovation can be harnessed to achieve their potential for social benefit.

[16] Chien founded the Paper Prisons Initiative,[17] which draws attention to the tens of millions of Americans unable to access employment, housing, voting, and resentencing opportunities available under the law, due to their past involvement with the criminal justice system.

[18] Chien has also worked on patent quality issues,[19] including testifying before the Senate Judiciary Committee.

Policy recommendations that she and her co-authors, in law review articles and other fora, have made have been adopted by the U.S. Supreme Court, in Congressional bills, at the US Patent and Trade Office, and by 32 states.Other recognition Chien has received include:
