Having argued more than 60 appeals, Jessica Ellsworth focuses her practice on the Supreme Court and federal and state courts of appeals. She combines extensive experience in appellate courts with a keen ability to help clients solve the litigation challenges they face.

Jess has handled complex appeals arising from motions to dismiss through jury trials and spanning a wide spectrum of issues – from patent and trademark disputes to class certification, from statutory interpretation to contractual and jurisdictional issues.

Jess is a leader in administrative law where she regularly pursues and defends against Administrative Procedures Act challenges to government agency action, and she has a niche practice in litigating dispositive motions and appeals in False Claims Act (FCA) cases. She has represented clients in every federal court of appeals and a dozen state appellate courts.  In all these matters, she brings her appellate perspective to developing and managing case strategy to achieve her clients’ goals.

Hogan Lovells US LLP is known for its regular engagements on high-profile appellate mandates in the US Supreme Court, as well as in federal and state courts of appeal. Former Principal Deputy Solicitor General Neal Katyal shares leadership of the department with the highly regarded Cate Stetson, who recently hit a milestone of 100 arguments at appellate stage. Katyal is a minority appellate star, whose US Supreme Court legacy will include breaking Thurgood Marshall’s record for a number of arguments presented by a minority litigator. The past year saw Katyal take the lead on acting on behalf of the respondents in the closely watched case of Fulton v City of Philadelphia, which raises significant issues relating to religious rights and certification of same-sex couples as foster parents. Jessica Ellsworth’s wide-ranging practice includes multiple representations of clients in the higher education sector. Counsel Mitchell Reich is a rising star in the team.
