Paul J. Loh

Partner/t 213-955-9240/f 213-955-9250


An original founding member of Willenken, Paul Loh is among a small group of lawyers of his generation who has spent much of his professional career actually trying cases.  Paul has tried over 50 jury trials to verdict, and over 80 court trials and arbitrations. 

Paul’s practice focuses on the defense of Fortune 500 corporations in high stakes litigation involving product liability and major torts, white collar criminal defense and internal investigations, intellectual property, class actions, and complex business litigation.  Because of his substantial trial experience, major companies turn to Paul for some of the most challenging cases on their dockets and have engaged him just months or weeks before trial specifically to act as trial counsel.

Recognized by The American Lawyer as a Top Rated Lawyer in White Collar Criminal Defense, and selected by the Los Angeles Daily Journal in 2007 as a “Top 20 Lawyer Under 40,” Paul is a graduate of Harvard Law School, and he previously served as an instructor in trial advocacy at the University of Southern California Gould School of Law.  He began his career as a criminal defense attorney, defending individuals and corporations in matters ranging from homicide, to securities fraud and RICO.  He later joined Quinn Emanuel Urquhart & Sullivan LLP, before leaving to help form Willenken in 2002.

Paul is a native Mandarin speaker and he has defended major Taiwanese and Chinese corporations in U.S. civil and criminal litigation matters.  Such matters include claims of trade secret misappropriation, antitrust (including international cartels), copyright and trademark infringement, patent infringement, and cyber piracy.

Paul is an avid baseball fan and, in his spare time, he enjoys running and traveling with his family.  He aspires to take his young daughters to visit all 50 states of the union before they leave the nest.
