Co-Leader of the Commercial Litigation Practice Group and member of the firm’s Banking, Bankruptcy & Creditors’ Rights Practice Group, Patrick Lannen has been integral to the growth and success of the firm’s high stakes and bet-the-company commercial practice.

Mr. Lannen is widely recognized for complex commercial and financial services litigation, banking and creditors’ right matters, and class, mass and multi-district actions.

In 2022 alone, Mr. Lannen tried four cases to verdict, over more than 28 days of trial in state and federal court, with more than $50 million or greater in exposure. He prevailed in full in each. The victories included landmark decisions in contract disputes, fraud cases, civil RICO, and regulatory cannabis issues of first impression.

While he has extensive experience in every facet of litigation in federal and state courts, from drafting the initial pleadings through the handling of trial and appeals, Mr. Lannen has particularized expertise in international contract disputes and finance restructures. In one such matter, he led a team that obtained a multimillion dollar judgment against a global manufacturing automotive corporation arising from a complex debt restructuring.

Having taken and defended hundreds of fact and expert depositions, successfully argued numerous motions, and having tried cases, Mr. Lannen represents Fortune 500 companies, as well as individuals throughout the country. He prepares to take matters to verdict, in an era when approximately 95% of cases settle.

While he is known to be a fierce litigator, Mr. Lannen also helps clients anticipate large-scale litigation risks before they happen to prevent wide scale litigation. In one case, he oversaw the use of arbitration agreements for thousands of employees for a national pizza chain that resulted in hundreds of dismissals of individual wage-and-hour claimants. Mr. Lannen obtained summary judgment on the issue of the interplay between the Federal Arbitration Act and the Fair Labor Standards Act, even on the collective action level, a milestone decision cited by the Harvard Law Review.  

Mr. Lannen regularly writes and speaks on class action and finance litigation topics.
