David Herron, former Chair of O’Melveny’s Electronic Discovery and Document Retention Practice, has dedicated his practice almost exclusively to eDiscovery litigation, advice and counsel in matters ranging from complex, multi-district litigation, to federal and state court-based class actions, and other disputes.

O’Melveny’s eDiscovery practice is well-regarded for its experience in handling of major eDiscovery litigation, and is known for providing experienced, proactive and defensible advice on cutting-edge eDiscovery issues that confront the Firm’s clients. David and his eDiscovery colleagues handle and advise on all aspects of eDiscovery preparedness and compliance, which includes advising about the design and implementation of defensible, effective and cost-contained document retention, collection and review programs; managing eDiscovery throughout the entire litigation life cycle; and litigating eDiscovery preservation, collection and production issues. David also has deep experience in litigating and defending corporations against attacks on their eDiscovery compliance, and pursuing and defending claims of evidence spoliation.

Perhaps the largest eDiscovery case in US litigation history, AMD v.
