What Cozen O'Connor does
Cozen O'Connor is a full-service U.S. law firm headquartered in Philadelphia, Pennsylvania, founded in 1970 and operating as a private professional corporation. The firm employs over 1,000 attorneys across 35 offices in the United States, Canada, and the United Kingdom, and is ranked among the top 100 law firms in America with reported gross revenue of approximately $800 million. Its core legal practices span litigation (including class actions and product liability), corporate and M&A, intellectual property, real estate, labor and employment, technology/privacy/data security, and government relations; ancillary wholly-owned businesses extend the platform into public strategies, strategic communications, cybersecurity advisory, family office services, subrogation, e-discovery, and legal technology. The firm is a member of the Am Law 100 cohort and serves global Fortune 500 corporations, middle-market and growth-stage companies, and high-net-worth individuals.
The firm's revenue model follows traditional professional services billing — hourly rates, fixed fees, contingency arrangements, and retainer agreements on multi-year enterprise engagements — with client acquisition driven by attorney-led business development, reputation, and industry recognition (Chambers USA, IAM Patent 1000, Best Lawyers, U.S. News Best Law Firms). On the technology side, Cozen O'Connor has adopted DeepJudge for AI-enhanced legal research and knowledge management and has piloted Laurel and Harvey AI, with deployment decisions governed by a structured evaluation framework led by its Chief Strategy and Innovation Officer. The firm is led by Executive Chairman and CEO Michael J. Heller, who has been unanimously re-elected to multiple terms.
