What WilmerHale does
WilmerHale (legally Wilmer Cutler Pickering Hale and Dorr LLP) is a private international law firm formed in 2001 through the merger of Wilmer Cutler Pickering and Hale Dorr. The firm operates from 12 offices across the United States (Boston and Washington DC as dual headquarters; New York, Los Angeles, Palo Alto, San Francisco, Denver, Dayton), the United Kingdom (London), Belgium (Brussels), and Germany (Berlin and Frankfurt), with more than 1,100 lawyers and a workforce of 1,001-5,000. It is governed as a limited liability partnership owned by its equity partners, with a Managing Partner, Deputy Managing Partner, and Management Committee, and has no parent company or external investment backing.
The firm's practice is organized around four core platforms - Corporate (M&A, capital markets, private equity, venture capital, emerging companies, cross-border transactions), Litigation (complex commercial disputes, government and regulatory litigation, white collar defense, international arbitration), Regulatory and Government Affairs (FDA, SEC, USTR, FTC, sanctions, customs, government contracts), and Securities and Financial Services - supplemented by specialized groups in Intellectual Property, Antitrust and Competition, International Trade, Cybersecurity, Artificial Intelligence, and Crisis Management. Supporting service lines include DiscoverySolutions (integrated e-discovery and document review) and a thought-leadership program (the In the Public Interest podcast, client alerts, and topical blogs). More than 100 lawyers hold senior government credentials spanning the USTR, DOJ, Solicitor General's office, SEC, FTC, FCC, FBI, CIA, and State Department.
WilmerHale generates revenue through the traditional professional-services billing model: hourly rates and matter-specific fixed fees for high-stakes legal work, delivered via partner-led teams to enterprise clients across financial services, life sciences, technology, media, and other regulated industries. The go-to-market is direct partner relationships and lateral-hire-driven capability expansion, supported by thought leadership and rankings (Top 3 American Lawyer A-List 2025; 2025 Law Firm of the Year; Chambers, Legal 500, Benchmark, Best Lawyers, Vault placements). Named engagements include the Biogen/Apellis $5.6B acquisition, Netflix patent defense, the NYT/Palin defamation victory, the Silicon Valley Bank receivership matter, Anthropic's DOD blacklisting challenge, and ongoing securities-litigation defense for Norfolk Southern.
