​Natalie Arbaugh is a trial lawyer and Principal in the Dallas office of Fish & Richardson. Ms. Arbaugh has a passion for top-notch client service, creative problem solving, and court​room excellence.  Natalie’s clients view her as a trusted legal advisor—a collaborative partner who helps guide them to a "win" in solving their problems, whatever form that win may take.  She recognizes that her clients need and deserve well-thought out strategic advice to guide them toward the best solutions for their business problems.  Her clients are her priority, twenty-four/seven.​

Ms. Arbaugh 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.  Her practice emphasizes general business and IP litigation, with an emphasis on trademark/anti-counterfeiting litigation, trade secret, non-compete and non-solicitation counseling and litigation.  Additionally, Ms. Arbaugh handles qui tam/False Claims Act litigation, copyright litigation and other general business litigation, including class actions, breach-of-contract, fraud, and breach of fiduciary duty, as well as employment litigation.​

Ms. Arbaugh has led over a hundred trademark infringement matters on behalf of leading luxury fashion designers, and as part of her clients’ national anti-counterfeiting campaigns. In a recent case, Ms. Arbaugh obtained sanctions against her opponent after methodically building a case to show that the defendants falsified and modified evidence, committed perjury, and committed fraud on the United States Patent and Trademark Office in conjunction with applying for a federal trademark registration—all in an effort to defend against her client’s claims of trademark infringement and to convince the court that the defendant had trademark rights superior to those of her client. Ms. Arbaugh resoundingly convinced the court otherwise, and obtained summary judgment and $38M in trebled damages on behalf of her client.  In awarding Fish 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 case was covered by Law360 (November 2014 and July 2015)

Ms Arbaugh has tried nearly 30 cases as lead counsel or second chair, including many high-profile matters. Before she reached the age of 40, Ms. Arbaugh was co-lead counsel and tried one of the largest and most complex fraud cases in Texas history. That effort took place over eight years, included the review of millions of pages of documents and over 150 depositions, and resulted in the largest Medicaid fraud settlement in Texas.  The record-breaking case resulted in Fish being named a Litigation Department of the Year finalist and contributed to Ms. Arbaugh being named a 2014 "Winning Woman" by Texas Lawyer Magazine.  Ms. Arbaugh also was a key member of the trial team for the widely publicized insider trading case brought by the Securities and Exchange Commission against billionaire entrepreneur and long-time Fish client, Mark Cuban. The jury cleared Mr. Cuban of any wrongdoing following a three-week trial in Dallas federal court.  This trial earned Fish’s litigation department to be named among Texas’ best in 2014.

Ms. Arbaugh’s passion for top notch client service and courtroom excellence have led to many honors.  Most recently, Natalie was chosen as a "Winning Woman" by Texas Lawyer (2014) and as one of the Best Lawyers in Dallas by D Magazine (2014-2015). Natalie was also frequently named a "Rising Star" by Texas Monthly Magazine, recognizing top and up-and-coming attorneys in Texas (2005, 2007, 2008, 2009, 2010, and 2011).

Following law school, Ms. Arbaugh served as a law clerk to the Honorable Deborah Hankinson of the Texas Supreme Court.

Ms. Arbaugh and her husband Jesse, a dentist, have been married for ten years. They have one daughter who is ten years old and enjoys running the household.  In her free time, Ms. Arbaugh enjoys college football, yoga, volunteering as a Court Appointed Special Advocate (CASA) and taking part in Attorneys Serving the Community, an organization that brings together women lawyers to combine their resources and talents to support local nonprofit organizations whose programs benefit women, children, and families.
