A founding member of the firm, Paul Loh is a rarity among lawyers of his generation in that he has spent much of his professional career actually trying cases. Upon graduating from Harvard Law School in 1992, Paul immediately knew he wanted to be a trial lawyer and he set upon a deliberate path to try cases of a multitude of subject matters and sizes. Paul has now tried over 120 jury trials, court trials, and arbitrations.

Paul represents Fortune 500 and other major corporations in high-stakes disputes involving complex commercial litigation, product liability and major torts, white collar defense and government investigations, and class actions. Because of his substantial trial experience, major companies turn to Paul to prosecute or defend some of the most challenging cases on their dockets, and they have engaged him just months or weeks before trial to take over as lead trial counsel.

Paul approaches legal problems with the keen and realistic eye of a seasoned trial lawyer: from the inception of each case, he prepares fully as if it will go to trial. First, he probes and breaks down the key facts to formulate a core narrative and trial theme for conveying his client’s position. He then conducts focused discovery and initiates strategic legal motions to build on the narrative methodically, ultimately solidifying it into a compelling, authentic story. Concurrently, if he determines that a case should settle short of trial because the facts and law so warrant, Paul will not hesitate to advise his client to do exactly that.

Recognized as a “Top Rated Lawyer” by The American Lawyer and a “Local Litigation Star” by Benchmark Litigation, Paul has spent nearly 30 years honing his craft in civil and criminal litigation. He began his legal career as a criminal defense attorney, trying cases on behalf of individuals and corporations facing charges ranging from homicide to securities fraud and RICO. He then practiced commercial and criminal litigation at an Am Law 100 firm before leaving to form Willenken in 2002. Paul is a native Mandarin speaker and has defended both major Asian and American corporations in 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 is currently an instructor for the National Institute for Trial Advocacy (NITA), and 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, for which he has served on its board since 2012.

Willenken Wins Critical Liability Phase of High-Profile Lupron Supply Shortage Trial in Delaware Chancery Court
Willenken Secures Full Dismissal of Telecommunications Lawsuit
Firm Obtains Seven-Figure Breach of Contract Settlement on Behalf of National Retailer

The following is a representative sample of Paul’s casework:

  • Abbvie Endocrine, Inc. v. Takeda Pharmaceutical Company. Lead trial counsel for AbbVie in a high-stakes breach of contract case brought before the Delaware Chancery Court against Takeda Pharmaceutical Company for failing to supply AbbVie’s requirements for Lupron, the leading androgen deprivation therapy for the treatment of advanced prostate cancer, uterine fibroids, endometriosis, and precocious puberty. The matter arose out of serious quality deficiencies identified by the FDA at one of Takeda’s Japanese manufacturing facilities, which led to supply disruptions and a world-wide Lupron shortage. This is a closely-watched case recognized by the pharmaceutical industry as “one of the five big healthcare lawsuits” of the year. Drawing on his immense trial experience, Paul led the Willenken team in preparing and bringing phase one of the case to trial on an intensive, expedited schedule, and presented a compelling case which led the Court to rule that Takeda is liable for multiple breaches of the parties’ supply agreement. The case is now proceeding to a phase two trial on damages.
  • 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. With team, obtained a complete dismissal of the action on motion to dismiss based on pre-emption by the Federal Telecommunications Act and for failure to state a claim for collusive conduct.
  • Nation’s Largest Investor-Owned Utility v. World’s Largest Polyethylene Pipe Manufacturer. On behalf of two prominent energy 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, seized the momentum and obtained a highly favorable confidential settlement which netted nearly 100% recovery on compensatory damages for the clients.
  • International Staffing Firm v. Leading Contract Manufacturer. On behalf of the world’s leading electronics component contract manufacturer, successfully counterclaimed against an international staffing firm for fraud and, one week before trial, procured a dismissal of the entire affirmative complaint and a public apology press release from the plaintiff.
  • Individuals v. Nation’s Largest Supplier of Business Products and Management Systems. 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.
  • California Attorney General’s Office v. National Solar System Provider. Defended and favorably resolved 10 administrative enforcement proceedings brought by the California Attorney General’s Office charging one of the nation’s largest solar systems providers with contracting license violations in connection with the financing and lease of residential solar energy equipment and systems.
