Dario Machleidt is an intellectual property litigator. He has represented clients in a wide variety of complex matters, including patent, copyright, trademark, and trade secret disputes. His experience includes litigating patent cases before the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court. Most recently, Mr. Machleidt was a member of the team that obtained a $20.3 million jury verdict on behalf of Kilpatrick Townsend client Dr. Mark A. Barry. On November 11, 2016, in Mark A. Barry, M.D. v. Medtronic, Inc., an East Texas jury found that Medtronic willfully infringed Dr. Barry’s patents and rejected Medtronic’s invalidity defenses. Mr. Machleidt conducted a direct examination and cross-examined a Medtronic witness during the seven-day trial. The National Law Journal recognized the verdict as one of the “Top 100 Verdicts of 2016.”

Between March and April 2014, Mr. Machleidt served as a Special Deputy Prosecutor in the King County Prosecuting Attorney’s Office. He served as co-trial counsel in five felony jury trials. Mr. Machleidt selected juries, presented opening statements and closing arguments, and examined numerous witnesses during his time as a Special Deputy Prosecutor.

Prior to joining Kilpatrick Townsend, Mr. Machleidt worked as an associate in the Seattle office of a national law firm. While there, he played a critical role in Bowman v. Monsanto Co., a pro bono patent case that reached the U.S. Supreme Court. He was the only associate to chair the Supreme Court oral argument. During law school, Mr. Machleidt served as a judicial extern for Judge Randall R. Rader of the U.S. Court of Appeals for the Federal Circuit. He was also a Comments and Articles Editor of the Pacific Rim Law & Policy Journal.
