Overview

William J. Barrow is an associate in Mayer Brown’s Washington DC office and is a member of the Intellectual Property Group. Bill protects and defends clients’ intellectual property rights in district courts throughout the country, before the US International Trade Commission (ITC), and before the US Patent and Trademark Office (USPTO). Having begun his career prosecuting electrical and computer software patents, Bill is often sought out for his understanding of the interplay between litigation and USPTO procedure. His experience in this regard leads to the early identification of favorable case strategies and mechanisms for implementing those strategies in concert with his clients’ business goals in mind. Clients rely on Bill not just to manage their matters, but as a trusted advisor to advance and protect their business interests before, during, and after litigation.

Bill’s litigation experience spans nearly ten years and countless industries, with a particular emphasis on consumer electronics, telecommunications, software, and automobiles. Bill has litigated cases from inception through trial, on the plaintiff and defendant side, and has counseled numerous foreign companies on navigating the US market. Bill also advises smaller businesses on how to leverage and protect their intellectual property.

Bill is frequently invited to speak and write on complex intellectual property issues, including IP valuation, licensing, and post grant proceedings before the US Patent Trial and Appeal Board (PTAB). Bill is also substantially active in a number of legal organizations, devotes substantial time to advancing diversity and inclusion in the legal industry, and contributes regularly to various firm initiatives:

  • Bill recently served as Chair of the Intellectual Property Section of the National Bar Association (NBA)—the nation’s oldest and largest national network of predominantly African-American attorneys and judges. Bill has also served in various leadership roles on the Patent Litigation Committee of the American Intellectual Property Law Association (AIPLA).  
  • In 2018, Mayer Brown selected Bill as its Fellow for the Leadership Council on Legal Diversity (LCLD)—an organization of nearly 300 members, consisting of general counsel of major corporations and managing partners of the nation’s leading law firms, whose goal is to facilitate the development of diverse legal talent for positions of leadership.
  • Bill is the Chair and founder of Mayer Brown Black Lawyers (DC), an affinity group Bill established to foster and promote the recruiting and retention of African-American attorneys in Mayer Brown’s Washington, DC office. In addition to advancing the interests of this affinity group, Bill also works with firm management and the other affinity group leaders to identify ways to increase diversity and inclusion across the firm.
  • Bill also devotes a significant portion of his time to mentoring younger attorneys through his involvement in the NBA, AIPLA, and LCLD.
  • Bill is active in Mayer Brown’s pro bono program. In 2016, Bill helped secure the release of a client by successfully convincing the US Court of Appeals for the 7th Circuit that new case law should apply retroactively under Teague v. Lane.

Since 2014, Bill has been recognized as a "Rising Star" in intellectual property by Super Lawyers Magazine. In his spare time, Bill enjoys cycling and martial arts.
