Jessica L. Ellsworth

Having argued more than three dozen appeals, Jessica Ellsworth focuses her practice on the Supreme Court and federal and state courts of appeals. She also partners with regulatory colleagues in Administrative Procedures Act challenges to government agency action, with the white collar group in False Claims Act (FCA) litigation, and with colleagues around the firm on issues of personal jurisdiction. In all these matters, she brings her appellate perspective to developing and managing case strategy and crafting dispositive motions.

Jess combines extensive knowledge of and experience in appellate courts with a keen ability to help clients approach and solve the litigation challenges they face.

Whether the case involves the FCA, a challenge to federal agency action, sovereign immunity, statutory interpretation, patent infringement, or a contrary jury verdict, Jess helps clients craft winning appellate briefs. Well-versed in appellate argument, she then presents clear and cogent arguments on behalf of her clients in federal courts of appeals around the country (most recently, the Federal, Second, and Fifth Circuits) and in state appellate courts (most recently, in Florida, Pennsylvania, and Maine). Jess has been named a Super Lawyers Rising Star for appellate litigation in 2013, 2014, 2015, and 2016.

Jess follows developments in the law on the issues that matter to her clients, and her clients span the automotive, pharmaceutical, life sciences, and financial services industries, among others.  She has successfully litigated motions to dismiss, motions for summary judgment, and appeals across all these industries.

Before joining the firm, Jessica served as a judicial clerk to the Honorable Martha Craig Daughtrey of the U.S. Court of Appeals for the Sixth Circuit and the Honorable Rebecca Beach Smith of the U.S. District Court for the Eastern District of Virginia. While in law school, Jessica was named Best Oralist by then-U.S. Supreme Court Justice David Souter in the Harvard Law School Ames Moot Court Competition.
