“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. Daralyn has been selected by Benchmark Litigation as one of the top 100 trial lawyers in the United States, Chambers & Partners as one of the top 20 patent litigators in California, the Daily Journal as one of the top 100 lawyers and one of the top 75 intellectual property lawyers in California, and by Law360 as an Icon of IP and MVP.

Daralyn recently won a federal jury trial for Orange in which the jury cleared the company of a $60 million dollar trade secret misappropriation claim as well as hacking claims brought by Bay Area startup Telesocial. Daralyn regularly represents companies such as Twitter, LinkedIn, and Netflix in high stakes patent cases. She has served as lead counsel for Genentech in a series of cases enforcing the Cabilly family of patents, which have generated almost $4 billion in licensing revenue. She obtained a summary judgment victory for Twitter in a case seeking 5% of Twitter’s revenue, a result recently affirmed on appeal. She 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 in 2015. Daralyn has represented defendants in nationwide and international class actions, including defending The Gap against claims brought by 45,000 foreign contract workers challenging conditions in garment factories in Saipan and Google against click fraud in Google’s Adwords program. More recently, Daralyn won a defense jury verdict on behalf of the California State University against a class of over 170,000 CSU students contending that that fee increases amounted to double-billing.

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 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 recently won the American Bar Association’s closing argument competition at its annual litigation section meeting, besting three of the top litigators in the country. She has testified before the Federal Trade Commission and speaks frequently on intellectual property issues. She is a co-author of a two-volume practice guide on California civil trials.

In high school, Daralyn was the Canadian national independent school debate champion. She and Mark Lemley, as debate partners at Stanford, had the distinction of being demolished by the English National Champion Oxford debate team their freshman year.
