Jones Day

Jones Day is a global law firm that provides a wide range of legal services to corporations, financial institutions, government entities, and other organizations across numerous industries. Its practice areas include litigation, corporate law, finance, intellectual property, tax, labor and employment, and regulatory matters, allowing it to advise clients on complex transactions, disputes, and compliance issues. The firm serves clients domestically and internationally, drawing on its deep sector knowledge to tailor solutions to specific business needs and jurisdictional requirements. Jones Day’s approach emphasizes interdisciplinary collaboration, bringing together lawyers from different specialties to address multifaceted challenges faced by its clientele.

Headquartered in Cleveland, Ohio, United States of America, the firm maintains a substantial international presence with offices located in major business centers throughout North America, Europe, Asia, the Middle East, and Latin America. This geographic footprint enables Jones Day to support cross‑border matters and provide local insight while leveraging a unified global platform. The firm is widely recognized for its strength in high‑stakes litigation and its ability to handle large‑scale, sophisticated corporate transactions, attributes that have contributed to its standing among the leading legal service providers worldwide. In December 2020, Jones Day experienced a data breach involving its vendor Accellion, where threat actors linked to the Clop group accessed and posted confidential files; the firm confirmed the incident was confined to the vendor’s system, denied any direct network intrusion or ransomware event, and initiated investigations and client notifications in response to the event. Structurally, Jones Day operates as a partnership, with its lawyers serving as partners and owners of the firm, and it does not have a parent corporation or external shareholders. This partnership model underpins its governance and aligns the interests of its legal professionals with the firm’s long‑term client service objectives.
