Mark S. Werbner

Mark S. Werbner is considered by his peers to be one of the nation’s most accomplished trial lawyers. He has extensive courtroom experience, having tried more than 150 jury cases across a broad range of areas throughout Texas and the United States. Helping businesses as well as individuals, Mark’s focus is on complex business litigation and white-collar criminal defense. 

Mark remembers the many times he has stood in a courtroom with his client before a verdict is read, and he understands what an important moment that is in a person’s life. As both a trial lawyer and counselor, he sees it as his job to listen to potential clients, to learn as much about their situation as he can, and then to show what he can do to help them.

Practice Areas:  Business Litigation, White Collar Criminal Defense, Healthcare Fraud, Securities & Financial Fraud

Representative Cases

Mark’s courtroom accomplishments include some of the largest jury verdicts in the country, and his work has been widely recognized by both his colleagues and the press. He is lead co-counsel for Terror Victims v. Arab Bank, a groundbreaking international terrorism lawsuit that has been featured on the Fox News Channel, Court TV, The Wall Street Journal, and other national and international media. In 2014, Mark helped convince a New York federal jury to issue liability findings against Arab Bank, clearing the way for a financial damages trial. The verdict represented the first time in U.S. history that a foreign bank has been found liable for materially supporting terrorism.

In May 2015, Mark argued and won a U.S. Supreme Court ruling in a patent infringement case where the firm previously had won a sizable judgment. The original jury verdict was recognized by VerdictSearch and Texas Lawyer newspaper as one of the top 10 verdicts statewide in 2011. 

In October 2017 Mark returned to the U.S. Supreme Court, as it considered whether corporations could face liability for violating the Alien Tort Statute in Jesner v. Arab Bank.
