For more than two decades, Jim Cox has successfully advised clients on their most challenging and difficult matters in litigation and arbitration. Jim's experience includes complex technology-related disputes, international disputes, class actions, and disputes involving corporate acquisitions. Jim is now applying that legal experience, together with his background in computer science, to the innovative fields of cryptocurrency and the blockchain, addressing Bitcoin, Ethereum, and other virtual currencies, as well as broader applications of distributed-ledger technology.

Jim has advised clients in dozens of matters around the country, including in litigation matters in state and federal courts involving claims based on a wide variety of legal theories. He also has significant experience with international legal disputes and has represented clients in matters pending before the ICC and other leading international arbitral institutions. Among other significant matters, Jim secured a judgment of $57.5 million, following a three-week arbitral proceeding, for claims relating to the acquisition of a business. He was also called in to take over the defense of a nationwide class action on behalf of a major computer services provider facing hundreds of millions of dollars in potential claims. The case settled favorably just before the class certification hearing.
