K&L Gates LLP

What K&L Gates LLP does

K&L Gates LLP is a global law firm formed in 2005 through the merger of Kirkpatrick & Lockhart (with roots dating to the 1880s) and Gates & Ellis (established in the 1940s), operating today as an integrated international legal platform with approximately 42 offices across the United States (20), Europe, the Middle East, Asia, Australia, and South America. The firm serves three primary customer segments: multinational corporations, government and public entities, and financial institutions and investors, providing comprehensive legal services across corporate/M&A, litigation, energy, financial services, intellectual property, government affairs, and emerging areas including AI governance and data center infrastructure. K&L Gates is recognized with 28 practice rankings in Chambers Global 2026 across 17 jurisdictions and nearly 40 practice rankings in Legal 500 EMEA 2026.

The firm's core product is professional legal services delivered through partner-led client relationships, with billing structures including hourly rates (e.g., partner rates up to £1,100/hour in London), fixed fees, and contingent arrangements depending on matter type. K&L Gates has invested substantively in AI tooling, deploying Legora as its primary AI platform firm-wide alongside Westlaw Precision AI, Vincent, and Microsoft 365 Copilot for legal research, drafting, and contract review. The firm achieved ISO/IEC 42001:2023 certification for its AI Management System (one of the first major law firms globally), maintains ISO 27001 and ISO 27701 certifications, and created a Global AI and Innovation Partner role to coordinate AI strategy, governance, and workflow automation across the platform. Revenue is not publicly disclosed; headcount of 1,001–5,000 and the firm's positioning within the Am Law 100-tier imply annual revenue in the $1B–$5B range, though the firm operates through a partnership structure with no external equity ownership.
