David’s second career, as a trial lawyer and patent litigator, follows a career in professional baseball that spanned five seasons. His journey as a minor-league catcher and coach in the Seattle Mariners, Oakland A’s, and Texas Rangers organizations was chronicled by Texas Lawyer and by Baylor Law School’s Rocket Docket, which described his most recent baseball adventure as a member of New Zealand’s 2012 World Baseball Classic team.

David’s passion to compete and win has translated well into his legal pursuits. With more than a dozen years of law practice under his belt, David enjoys litigating complex cases across multiple fields, including intellectual property, business, oil and gas, sports and entertainment, and consumer-related matters.

David’s courtroom experience, which includes numerous first-chair engagements, includes successful trials in both federal and state court, in Texas and outside of Texas. Since 2007, he has focused the vast majority of his time and efforts representing plaintiffs in high-stakes patent litigation. He was elected by his fellow IP lawyers to serve as Chair of the Tarrant County Bar Association’s Intellectual Property Section from 2009 to 2010.
