About Jason M.
Jason M. Wilcox built a career that moves between appellate benches and the conference rooms of a major law firm. He has a background in both technology and law, and his path has been marked by two prominent federal clerkships and steady advancement at Kirkland & Ellis.
He completed his undergraduate studies at Portland State University, earning a B.S. in computer science in 2004. He then turned to law and graduated from The University of Chicago Law School in 2009. Those two degrees—one technical, one legal—shape the contours of his practice.
After law school, Wilcox spent consecutive years on the federal bench. He clerked for Judge Jeffrey S. Sutton on the United States Court of Appeals for the Sixth Circuit in 2009. The following year he served as a law clerk to Justice Antonin Scalia at the Supreme Court of the United States. Those clerkships exposed him to high-stakes appellate work and to the procedural rigor required at the highest levels of the judiciary.
Wilcox joined Kirkland & Ellis LLP and rose through the firm’s ranks. He became a partner in 2015. At the firm he has worked on matters that reach federal trial courts and appellate panels. He is admitted to practice in Texas and in the District of Columbia, and he holds admission to the United States District Court for the Western District of Wisconsin and the United States District Court for the District of Colorado. Those admissions reflect frequent appearances in federal forums.
Outside the courtroom he maintains memberships in several bar and professional organizations. He is listed in the State Bar of Texas (since 2011) and the District of Columbia Bar (since 2012). He also participates in the Federal Circuit Bar Association, the Federalist Society, and the J. Reuben Clark Law Society. These affiliations place him in networks that address appellate procedure, federal practice, and the intersection of law and public policy.
Colleagues describe his background as one that combines technical training and appellate experience. His time on appellate benches informs how he frames legal arguments and structures briefs. At the firm he handles matters that require careful presentation to judges and juries, and he regularly prepares appeals for higher courts.
As of 2026 Jason M. Wilcox is a partner at Kirkland & Ellis LLP, where he practices in federal and appellate litigation.
