Co-leader of Plunkett Cooney’s Commercial Litigation Practice Group and a 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 his success in all aspects of banking, bankruptcy and commercial litigation. He has particular expertise involving UCC Articles 2 and 9, and real estate cross-border contract disputes. While he has extensive experience in every facet of litigation in state and, particularly, federal courts, Mr. Lannen has substantial experience representing commercial banks, funds and special servicers in receiverships, enforcements, debt sales and restructure.

In addition, he has considerable experience drafting origination documents for multi-loan facilities and syndicated transactions. For example, Mr. Lannen has led or participated in dozens of mortgage loan originations for properties involving mines, wetlands, multifamily, manufacturing and retail assets throughout Michigan, Ohio, Indiana, Canada, Florida, New York, and Wyoming with transaction values exceeding $3 billion.

Mr. Lannen has taken more than 120 cases to completion in federal court with more than 80 summary judgment grants. In 2022 alone, he 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 has had significant success defending class actions, having obtained multiple dismissals of putative representatives’ claims and denials of certification.  

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.  

A member of the firm's Board of Directors, Mr. Lannen regularly writes and speaks on class action and finance litigation topics.
