Dave De Bruin is a creative and seasoned first-chair patent trial and appellate lawyer. Chambers USA: America's Leading Lawyers for Business has characterized Dave as an "impressive litigator," citing sources stating he possesses "an extremely acute legal mind" and noting his "ability to think his way around any issue." While Dave is well-equipped to argue legal issues and to explain complex technology to lay judges and juries, he understands that at trial, the human story behind the dispute must be told. He also understands that litigation may not always be the best approach to achieve a client's goals.

Dave has successfully tried patent cases in a variety of venues. In 2009, he obtained a liability jury verdict in the Central District of California on a patent covering 3D computer modeling in orthodontics, leading to a recovery publicly valued in excess of $90M. Dave has first-chaired jury trials in the rocket docket of the Western District of Wisconsin and, in a last minute substitution of lead trial counsel, obtained a willful infringement finding against Walmart in the District of Colorado. The technology in Dave's cases have ranged from mechanical and electrical devices to biological and chemical patents.

Although he is admitted to the U.S. Patent and Trademark Office and has a physics degree from M.I.T., Dave's judgment as a litigator is informed by the substantial non-patent business litigation he lead during the first decade and a half of his career, which included securities fraud, RICO, insolvency and telecommunications fraud, and first-chairing a five-week long accountant liability trial that remains a leading accountant liability and attorney misconduct case in Wisconsin.

Dave has successfully argued numerous patent cases before the Federal Circuit Court of Appeals and prepared an amicus brief whose arguments were noted in a recent en banc ruling. He also has served as an arbitrator deciding securities claims and IP insurance coverage issues and submitted testimony as a Markman expert. Dave also authors patent opinions and provides IP counseling.
