Ragesh Tangri has represented clients ranging from individuals to Fortune 100 companies in a wide variety of cases and in jurisdictions across the country.

He recently represented Volt Delta Resources LLC and Maintech Inc. in a copyright infringement and false advertising lawsuit brought by Oracle regarding Maintech’s provision of hardware support for Sun servers.  Oracle alleged that Maintech and co-defendant Terix infringed Oracle’s copyrights to its Solaris operating system by providing third-party maintenance services to their customers.  The case was resolved in June 2015.  Ragesh represented Google Inc. in a high-stakes breach of contract matter brought by teleconferencing company Wyde Voice in San Francisco Superior Court.  He successfully defended Palo Alto Networks against a far-reaching trade secret misappropriation and patent infringement case targeted at PAN’s revolutionary next-generation firewall products.  The federal district court granted summary judgment for PAN on all of the trade secret misappropriation claims, finding the plaintiff time-barred by the statute of limitations.  Shortly thereafter, the plaintiff agreed to walk away from his patent infringement claims in exchange for an agreement that PAN would not pursue attorneys’ fees.  Ragesh defended a developer of Bluetooth devices against trade secret misappropriation, unjust enrichment and tortious interference claims in the Western District of Texas. He has represented numerous start-up companies in claims brought by former business partners and persons claiming to co-founders, often centering on allegations of trade secret misappropriation or copyright infringement.

Ragesh has represented numerous major law firms in professional negligence claims, arising from work done in a variety of underlying areas including intellectual property litigation, patent prosecution, general corporate matters, and tax.  He has represented clients in claims alleging incorrect labeling of nutritional supplements.

Ragesh also has represented the selling shareholders of numerous companies in litigation arising from post-closing matters, including both claims against buyers for failure to pay contingent compensation and claims brought by buyers against escrowed consideration. 

Prior to founding Durie Tangri, he represented Google, Inc. and Kai-Fu Lee in a trade-secret and non-compete claim brought by Microsoft, resulting in Dr. Lee's being permitted to take a position with Google in China. He represented Intel Corporation in litigation brought by Frank Shum concerning the inventorship of patents, as well as damages claims under state law. He assisted Broadcom in its dispute with Qualcomm, litigating the scope of the exclusion order to be granted by the United States International Trade Commission. And he helped represent Cadence Design Systems in its long-running dispute with Avant! Corporation, including arguing the successful Ninth Circuit appeal of the district court's denial of a preliminary injunction, and participating in a multi-week criminal restitution hearing that led to an award of over $180M.

Ragesh clerked for the Hon. A. Raymond Randolph on the United States Court of Appeals for the District of Columbia Circuit. He joined Keker & Van Nest in 1994 and became a partner there in 1999. He has taught the Introduction to Civil Procedure and Law on Lawyering courses at Boalt Hall, and spoken frequently on issues including trade secret law, professional negligence, ethics, claim construction, and the differences between the U.S. and Canadian legal systems.

Ragesh serves on the Boards of Governors of the Association of Business Trial Lawyers, the Bar Association of San Francisco’s Justice and Diversity Center, the Northern District Historical Society (President), the California Law Review, The Shotgun Players, and the Food Craft Institute, as well as Membership Chair and Member of the Executive Committee of the Edward J. McFetridge Inn of Court.  He previously served as a member and co-chair of the Lawyer Representatives of the Northern District of California to the Ninth Circuit Judicial Conference, as a member and Chair of the BASF’s Judiciary Committee and as a member of the Board of Directors of Slow Food Nation. 

Ragesh was named as one of the Best Lawyers’ 2016 Lawyers of the Year in Northern California.  He has been recognized by Chambers & Partners as a leading practitioner in Intellectual Property, and ranked by Best Lawyers for Bet-the-Company Litigation, Commercial Litigation, Legal Malpractice Law, Intellectual Property and Patent Litigation, Patent Law and Trade Secrets Law.  He has been ranked by SuperLawyers as a top rated intellectual property litigation attorney from 2005 through 2016 and was ranked as one of the Top 100 Attorneys in Northern California in 2011, 2012 and 2013.
