Paul J. Loh

Paul Loh, a founding partner of Willenken LLP, is a nationally recognized trial lawyer who has spent his career in the courtroom. Over more than three decades, he has tried more than 120 jury trials, bench trials, and arbitrations. He is routinely called upon to serve as lead trial counsel for Fortune 500 companies and other major corporations in their most consequential disputes, including matters taken over on the eve of trial. He has secured significant victories in matters involving complex commercial litigation, class actions, intellectual property, product liability and mass torts, and white collar defense and government investigations.

Paul’s depth of trial experience is rare among practitioners of his generation, and his record reflects both the scale of the matters he handles and the results he delivers. He recently led a Willenken team that secured a judgment exceeding $500 million on behalf of a leading pharmaceutical company following trial in the Delaware Court of Chancery. This result earned the firm Benchmark Litigation’s 2025 “Impact Case Award.”

Paul’s ability to distill complex legal and factual issues into clear, compelling trial narratives—and to execute decisively under pressure—makes him a trusted advisor in bet-the-company litigation. He approaches every engagement with a rigorous, trial-first mindset. From the outset, he identifies the core themes that will resonate at trial and builds each phase of the case—fact development, motion practice, expert strategy, and presentation—around that narrative. At the same time, he provides clear-eyed, strategic counsel, advising clients when resolution is warranted and positioning them to achieve optimal outcomes, whether in the courtroom or at the negotiating table.

Paul’s work has been widely recognized by leading legal publications and industry peers. In 2026, he was named a “Leading Commercial Litigator” by the Daily Journal for the third consecutive year and was again recognized as one of the “500 Leading Litigators in America” by Lawdragon and as a “Litigation Star” nationally and in California by Benchmark Litigation. From 2021 to 2024, Paul was repeatedly recognized as a “Leader of Influence” by the Los Angeles Business Journal. In 2024, he was also named an “Attorney of the Year” finalist for the California Legal Awards hosted by Law.com’s The Recorder.

In addition to his practice, Paul is deeply committed to the development of trial advocacy. He serves as an instructor for the National Institute for Trial Advocacy (NITA) and previously taught trial advocacy at the University of Southern California Gould School of Law. He also remains dedicated to advancing access to justice and currently serves as the co-chair of the White Collar Defense and Internal Investigations Committee of the National Association of Minority and Women Owned Law Firms (NAMWOLF), is a member of the California Minority Counsel Program (CMCP), the National Asian Pacific American Bar Association (NAPABA), and the Defense Research Institute (DRI | Association of Lawyers Defending Business). From 2012 to 2026, Paul served on the board of Neighborhood Legal Services of Los Angeles, including as Board Chair.

Paul began his legal career as a criminal defense attorney, trying cases involving charges ranging from homicide to securities fraud and RICO. He later practiced at an Am Law 100 firm before co-founding Willenken LLP in 2002. He received his J.D. from Harvard Law School.

A native Mandarin speaker, Paul represents both U.S. and international clients, including major Asian corporations, in civil and criminal matters.
