Ragesh Tangri has represented clients ranging from individuals to Fortune 100 companies in cases ranging from legal malpractice and commercial litigation to high-stakes intellectual property and trade secret matters in jurisdictions across the country.
Ragesh recently represented a major California law firm accused of malpractice; a multi-week arbitration brought a favorable result for his client. He 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.
Ragesh recently invalidated four patents directed to nutritional supplements on a motion to dismiss. He has also represented clients in claims alleging incorrect labeling of nutritional supplements. He 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. He represented Google Inc. in a high-stakes breach of contract matter brought by teleconferencing company Wyde Voice in San Francisco Superior Court.
Ragesh 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 also defended a developer of Bluetooth devices against trade secret misappropriation, unjust enrichment and tortious interference claims in the Western District of Texas.
Ragesh 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. He 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. 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.
