Mark Murphey Henry, JD., LL.M.

Mark Murphey Henry, P.A.

Mark is AV-Preeminent™ rated, a distinction earned through years of consistently outstanding legal work and a reputation for integrity. With decades of experience as a registered patent attorney and an LL.M. in agricultural law, he has developed a deep focus on protecting agricultural seed technology. Mark works closely with universities and multinational companies to navigate complex intellectual property matters and ensure long-term protection of innovation. He has handled more than 100 cases under the Plant Variety Protection Act, bringing a wealth of practical insight to the defense of plant breeders' rights. In addition to his legal practice, Mark has contributed to the field as an educator, teaching agricultural biotechnology law in the LL.M. program at the University of Arkansas School of Law.

Mark prosecutes and defends highly complex civil litigation and high-stakes, bet-the-company disputes involving trade secrets, patents, copyrights, and DMCA claims in federal courts across the country. His cases frequently address cutting-edge issues involving computer code, seed genetics, and architectural works. Licensed in six states and admitted to practice before the United States Patent and Trademark Office, he has served as lead counsel for clients in more than twenty-five states, offering broad strategic perspective and experience.

Mark brought one of the first cases under the Frank Broyles Publicity Rights Act, Ark. Code Ann. § 4-75-1101, helping to shape the early application of Arkansas’s right of publicity law. He successfully represented professional rodeo athlete Cody James in a case involving the unauthorized commercial use of James’s name and likeness. A decorated competitor, Cody has qualified for the Arkansas Rodeo Association Championships 22 times, is a seven-time ARA Champion, and has been named both Overall Rookie of the Year and Tie-down Roping Rookie of the Year by the Professional Rodeo Cowboy Association. Mark’s advocacy in Cody James v. Boot Barn, Inc., No. 4:22-cv-646-KGB (E.D. Ark. 2023), helped affirm the importance of protecting the identity and brand of professional athletes under Arkansas law.

He also serves as both trial and appellate counsel, offering a comprehensive approach to complex litigation. In Associated Electric Cooperative, Inc. v. Southwest Power Pool, Inc., Case No. 23-1293, (8th Cir. 2024), Mark secured a significant trial and appellate victory, successfully defending a $37.64 million claim in an energy dispute involving tariffed energy rates. The Eighth Circuit agreed that SPP had fully compensated AECI for the transactions in question and held that equitable recovery theories are not available when an express contract governs the parties’ relationship.

Mark is also known for taking a principled stand against improper litigation conduct. In Lyon v. The Academy, Inc., 2024 Ark. App. 386, he obtained Rule 11 sanctions against opposing Arkansas counsel Matthew Campbell and Elizabeth Lyon. The Arkansas Court of Appeals affirmed the sanctions, finding that their claims were frivolous, had no chance of success, and were brought solely to harass and drive up litigation costs—highlighting Mark’s commitment to professionalism and the integrity of the legal process.

When disputes arise with Walmart, Mark provides trusted counsel to both large and small vendors. Given that Walmart is headquartered in Northwest Arkansas and most of its contracts require disputes to be litigated in Benton County, Mark’s location in Fayetteville—home to the federal court for Northwest Arkansas—positions him ideally to handle these matters efficiently and effectively.

Mark is admitted to practice before the U.S. Supreme Court, the U.S. Courts of Appeals for the Eighth and Federal Circuits, and several federal district courts, including the Eastern and Western Districts of Arkansas, the District of Nebraska, and the Eastern and Western Districts of Oklahoma. He also represents clients before the Trademark Trial and Appeal Board in trademark matters.
