Biography

Ryan Patrick is a partner in Haynes Boone’s White Collar and Government Investigations Practice. Ryan is an experienced investigator, judge and trial lawyer who has handled or supervised nearly every type of criminal and civil enforcement matter. There are few lawyers with Ryan’s unique experience. 

Ryan has spent his career in the courtroom, first as a state prosecutor, then as a Texas district court judge, and finally as the United States Attorney for the Southern District of Texas. From 2018 to 2021 Ryan oversaw one of the largest DOJ offices and the busiest criminal and appellate docket in the country.

Ryan has handled a broad array of white-collar and traditional criminal cases in federal and state court, including False Claims Act, Foreign Corrupt Practices Act, and money laundering. He has both investigated and represented foreign actors, elected officials and corporate defendants in the banking, biotech, energy, healthcare, and space industries. During his time as an assistant district attorney, Ryan was a specially trained prosecutor in the investigation of vehicular crimes cases, and he finished his state career assigned to the Special Crimes/Major Offenders section where he handled proactive investigations into the most complex and dangerous criminal organizations along with other one-off exceptional cases. Two of his final trials as state prosecutor was securing a life sentence in a 30-year-old cold case murder and the successful prosecution of a man who spray painted a gallery displayed Picasso.

Along with a robust federal defense practice, Ryan maintains a criminal state practice representing individuals and companies investigated or charged under Texas criminal statutes. Ryan is the first call from his partners at Haynes Boone for state criminal matters – from corporations facing state Attorney General civil investigations to individual clients under arrest or investigation for any number of crimes across the state.

Ryan’s extensive experience in the courtroom is evidenced in more than 50 first and solo chair jury trials and oral arguments before the 5th Circuit Court of Appeals. As a judge Ryan presided over more than 100 jury trials in four and a half years on the bench.

Having earned his private pilot’s license in 2007, Ryan’s knowledge and passion in aviation has helped him advise clients involved in FAA civil investigations and having been a state elected official, Ryan’s knowledge of the Texas Ethics Code has benefited firm clients navigating state campaign finance laws.
