“There are few trial lawyers in the exclusive world of Silicon Valley high-tech circles as trusted as Daralyn Durie,” says Lawdragon’s 500 Leading Lawyers in America. Chambers & Partners reports that she is “out-of-this-world good. She has great instincts, is a great thinker and is just phenomenal.” She has been selected by Benchmark Litigation as one of the top 20 trial lawyers in California and one of the top 100 trial lawyers in the United States, Chambers & Partners as one of the top 6 patent litigators in California and one of the top 10 intellectual property lawyers nationwide, Super Lawyers as one of the top 10 lawyers in Northern California, the Daily Journal as one of the top 100 lawyers in California, and by Law360 as an Icon of IP and MVP. Benchmark Litigation reports that “going against her was like going against a boxer in which you know you’re going to get hurt.”
Daralyn recently scored back-to-back wins in two of the first post-COVID in person jury trials, achieving a defense verdict for Activision Blizzard in a copyright infringement action in the Eastern District of Texas over Call of Duty Black Ops 4, and less than a month later winning $178 million and a finding of willful infringement in a patent infringement action against Novartis in the Northern District of California over a melanoma therapy. She has served as lead counsel for Genentech in a series of cases enforcing the Cabilly family of patents, which generated billions in licensing revenue, as lead counsel in high stakes biosimilar litigation over one of Genentech’s most successful products, and successfully defended Google against claims of copyright infringement arising from the scanning of works in major library collections, resulting in her being named one of California Lawyer Magazine’s Attorneys of the Year.
Following law school, Daralyn clerked for the Honorable Douglas Ginsburg on the United States Court of Appeals for the District of Columbia Circuit. She then began work at Keker & Van Nest as an associate and became a partner of the firm in January 1999. Daralyn co-founded Durie Tangri in 2009. Daralyn is a fellow in the American College of Trial Lawyers, a past President of the Board of Directors of the Northern California Association of Business Trial Lawyers, a former co-chair of the Lawyer Representatives to the Ninth Circuit Judicial Conference, and a court-appointed Early Neutral Evaluator for the Northern District of California. She has testified before the Federal Trade Commission, speaks frequently on intellectual property issues, and is a co-author of a two-volume practice guide on California civil trials. When not in trial, she can often be found riding on two wheels around California and beyond.
