Nathan Dooley


Nathan serves as counsel on high profile complex commercial litigation matters filed in California. He represents some of the firm’s most prominent clients. 

His successes include a string of victories in consumer class action cases brought in state and federal court.  He successfully defended class action claims brought against shippers, retailers, and cosmetic manufacturers. He also represented a group of corporate plaintiffs in a successful class action against a Chinese manufacturer of faulty dehumidifiers that caused hundreds of house fires across the country. He advises food manufacturers on matters related to contamination, labeling, trademarks, and intellectual property. He recently procured a large settlement on the behalf of a food manufacturer that suffered contamination of its product by a third party. 

Nathan has extensive trial and appellate experience in the intellectual property arena, where he has successfully prosecuted actions against salespeople and executives who wrongfully absconded with trade secrets to start their own firms. He successfully defended engineers and entrepreneurs accused of misappropriating trade secrets and copyright infringement after leaving large corporations to launch their own successful products. He has defeated claims of alleged trademark infringement, copyright infringement, and has substantial experience with high-profile patent litigation. 

Fluent in Korean, Nathan has led investigations into large claims in South Korea and served as trial counsel in an international arbitration against a large Korean corporation in the International Chamber of Commerce. Nathan’s trial victories extend to a Grammy-Award winning music producer, and he has quashed attempts to extort public figures with libelous accusations, discretely handling such matters without any publicity. 

He earned his law degree from the University of California Berkeley School of Law (Boalt Hall). After law school, he clerked for the Honorable Carolyn B. Kuhl of Los Angeles Superior Court, the Honorable S. James Otero of the U.S. District Court for the Central District of California, and the Honorable Arthur Alarcon of the Ninth Circuit Court of Appeals. He earned a master's degree from Queen's University in Canada and a bachelor's degree from the University of Saskatchewan.
