Ben Hattenbach is a partner in the Los Angeles office of Irell & Manella LLP, where he serves as a member of the firm’s Executive Committee. His practice focuses on intellectual property litigation and counseling, with particular emphasis on the trial of patent infringement matters.
In each of the past seven years, the Los Angeles and San Francisco Daily Journals named Mr. Hattenbach one of the top 75 intellectual property litigators in California. He has been described as “an exceptionally talented patent litigator who fully dedicates himself to his clients,” “fantastically smart” and "super-bright, creative and tenacious" (Chambers USA), “amazing” and "one of the country's best patent attorneys under 40” (The Legal 500), and “just fantastic” and “a tactically clever lawyer who thinks 15 moves ahead” (IAM 1000). Recently, while representing patent holders during a span of just eight months, he obtained five separate nine-figure verdicts and settlements, four of which had a value exceeding $200 million.
Mr. Hattenbach has litigated patent disputes before numerous federal and state courts, as well as the International Trade Commission and arbitration panels. He also regularly litigates contested proceedings, such as inter partes reviews, before the United States Patent and Trademark Office. On the transactional and counseling side, he provides strategic guidance regarding patent portfolio management, licensing and acquisitions. He is a registered patent attorney.
Mr. Hattenbach received bachelor’s and master’s degrees in Engineering, both with distinction, from Harvey Mudd College in 1992 and 1993, respectively. He received his J.D. degree from the University of California at Berkeley (Boalt Hall) in 1996, where he was admitted to the Order of the Coif and served as executive editor of the Berkeley Technology Law Journal.
In his spare time Mr. Hattenbach is an internationally published landscape photographer who enjoys exploring remote wilderness areas.
