Paul J. Loh

Partner/t 213.955.9240/f 213.955.9250


A founding member of the firm, 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 represents 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 as a “Top Rated Lawyer” by The American Lawyer, Paul has practiced complex civil and criminal litigation for more than a quarter of a century. He began his legal career as a criminal defense attorney, defending individuals and corporations in matters ranging from homicide to securities fraud and RICO. He then practiced complex commercial and criminal litigation at an Am Law 100 firm before leaving to form Willenken in 2002. Paul approaches legal problems with the keen and realistic perspective of a seasoned trial lawyer — if he believes that a case should settle or otherwise resolve short of trial because it is warranted by the facts, law, or business imperatives, he will not hesitate to advise the client candidly to do so. 

Paul is a native Mandarin speaker and he has defended major Asian corporations in United States civil and criminal litigation matters. As managing partner of Willenken, Paul enjoys working with and mentoring young and aspiring lawyers, both in the firm and the community. He previously served as an instructor in trial advocacy at the University of Southern California Gould School of Law. Dedicated to ensuring fair and equal access to justice for all in his community, Paul volunteers his time and resources to Neighborhood Legal Services of Los Angeles (NLSLA) and currently serves as president of the NLSLA Board of Directors.

Representative Matters

Representative Matters

  • Acumen Communications, Inc., et al. v. City of Covina et al. Defended Motorola Solutions in a business interference and bid-rigging suit concerning the provision of emergency response telecommunications systems to Southern California municipalities. Paul and his team obtained a complete dismissal of the action on motion to dismiss based on preemption by the Federal Telecommunications Act and for failure to state a claim for collusive conduct.
  • Confidential Matter. On behalf of two prominent utilities, prosecuted a large-scale breach of contract, breach of warranty, and fraud action against a major vendor for the supply of defective products and systems. After defeating defendant’s anti-SLAPP motion, Paul and his team seized the momentum and obtained a highly favorable confidential settlement which netted nearly 100% recovery on compensatory damages for the clients. 
  • Confidential Matter. Defended the nation’s largest supplier of business products and management systems in a putative nationwide class action alleging unlawful delivery and service charges in violation of the consumer protection statutes of 34 states, including California. Plaintiffs sought restitution of $1 billion in ill-gotten profits. While the plaintiffs' motion for class certification was pending, Paul and his team’s intensive investigation uncovered key impeachment evidence against the named plaintiffs. Paul leveraged these key revelations into a highly favorable, confidential individual settlement for the client, and then worked closely with the client to modify business practices to prevent or minimize the risks of future class action claims.
