People
Natalie Arbaugh is a trial lawyer with a passion for top-notch client service, creative problem solving, and courtroom excellence. Her extensive experience has led her to be recognized multiple times as one of Benchmark Litigation’s “Top 250 Women in Litigation,” ranked by Chambers USA, listed in The Best Lawyers in America®, selected to the Texas Super Lawyers list, and named “Winning Woman” by Texas Lawyer.
Natalie represents plaintiffs and defendants in a variety of industries in state and federal courts throughout the country in complex—and often high-profile—business and intellectual property disputes. From handling breach of contract matters to trade secret litigation to class actions, she is skilled at distilling even the most complex of business disputes into a simple story that resonates with judges and juries alike. Her intellectual property practice focuses on trade secret and departing employee issues, including noncompete counseling and litigation, and trademark litigation.
Natalie’s trial experience includes an eight-year case in which she co-counseled with the Texas Attorney General’s office to try one of the largest and most complex fraud cases in Texas history. Resulting in the largest Medicaid fraud settlement in Texas, this record-breaking case led to her prior law firm being named a “Litigation Department of the Year” finalist and contributed to Natalie being named a “Winning Woman” by Texas Lawyer. She also was a key member of the trial team for the widely publicized insider trading case brought by the SEC against billionaire entrepreneur Mark Cuban. Following a three-week trial in Dallas federal court, the jury cleared Mr. Cuban of any wrongdoing.
In an IP case covered by Law360, Natalie obtained sanctions against her opponent after methodically building a case to show that the defendants falsified and modified evidence and committed perjury and fraud in an attempt to undermine her client’s trademark infringement claims and assert superior trademark rights. She decisively persuaded the court otherwise, and following a bench trial, obtained a $42 million judgment for her client. In awarding her client its attorneys’ fees, the trial court judge stated, “Counsel’s skill and expertise has been evident throughout this litigation, and their performance under taxing circumstances has been impressive.”
The most fulfilling aspect of Natalie’s career is the strong relationships she builds with her clients. They rely on her as a trusted legal advisor—someone collaborative, innovative, and deeply invested in guiding them toward the best possible outcome, whether that means winning at trial, resolving a dispute early, or finding a creative business solution. Natalie understands that her clients need thoughtful, strategic counsel to navigate their most pressing challenges, and she treats their priorities as her own. She works closely with them to evaluate risks, make informed decisions, and resolve complex issues long before a case ever reaches the courtroom.
