Morrison & Foerster

What Morrison & Foerster does

Morrison & Foerster LLP is a global law firm founded in 1883 and headquartered in San Francisco, operating 19 offices across the United States, Asia, and Europe. The firm serves Fortune 100 companies, financial institutions, and leading technology and life sciences companies through partner-led client engagements, with practice depth in intellectual property litigation, complex commercial litigation, M&A, regulatory compliance, financial services, and emerging areas including AI, data privacy, and cybersecurity. Notable mandates include advising SoftBank on its $41 billion investment round in OpenAI, defending OpenAI and Anthropic in AI copyright litigation, and advising Sumitomo Forestry on its $4.5 billion acquisition of Tri Pointe Homes.

The firm's core technology layer centers on its June 2026 strategic partnership with Legora, which deploys AI as a firmwide platform for attorneys. The platform supports document review and analysis, automation of routine legal tasks, customized workflow building, and emerging agentic capabilities for multi-step task execution. Beyond the Legora deployment, MoFo distributes legal expertise through eight podcast series, nine specialized blogs, dedicated resource centers covering AI, cybersecurity, privacy, sanctions, and stablecoins, and an active alumni and client alert network. The firm pursues a hybrid client segmentation approach organized by both size tier (Fortune 100) and vertical (technology, life sciences, financial services).

The business model is a traditional professional services fee structure, with revenue generated through hourly rates, fixed fees for specific matters, contingency fees, and transaction-based fees that vary by practice area and engagement complexity. Pricing is quote-based and not publicly disclosed. MoFo operates as a limited liability partnership owned and controlled by its partners, with Eric T. McCrath serving as Chair; the firm is not publicly traded and has no parent company or external equity backing. Recent growth has been fueled by record financial results in 2025/2026, the 2023 Durie Tangri merger that brought approximately 36 IP and litigation lawyers, the February 2026 Seattle office launch staffed by 15 lateral partners, and the Legora AI partnership.
