Clint’s practice focuses on trial and appellate litigation in state and federal courts.

Prior to joining Lightfoot, Clint served as a law clerk to federal judges at the trial and appellate levels. After finishing law school, Clint clerked for the Honorable Jimmie V. Reyna of the United States Court of Appeals for the Federal Circuit in Washington, D.C. He assisted Judge Reyna with appeals related to administrative law, intellectual property, and money suits against the federal government, including appeals in patent, copyright, trademark, government personnel and contracts, international trade, takings, and vaccine cases.

Clint spent two years clerking for the Honorable Roy S. Payne of the United States District Court for the Eastern District of Texas in Marshall. The Marshall division hosted twenty-eight civil trials while Clint was there, twenty-two of which were jury trials. Clint assisted Judge Payne and other judges in the district with many of these trials and other proceedings, including more than forty patent claim construction (or Markman) hearings.

Between clerkships, Clint worked as a litigation associate at a large law firm in Washington, D.C., and Atlanta, Georgia. He gained experience in civil cases and proceedings before the United States Patent and Trademark Office, including reexamination and inter partes review. Before law school, Clint spent three years preparing and prosecuting patent applications and appeals at the USPTO.

Clint’s graduate research focused on organic, polymer, and materials chemistry.

Clint was born and raised in Florence, Alabama.
