Overall firm rank
Cooley's practice is closely associated with technology, life sciences and the investors that finance growing businesses. Its work includes company formation, venture financing, public offerings, acquisitions and investment-fund matters. The firm advises companies at different stages of development, from early ventures to established public businesses.
Life sciences is a particularly distinctive part of that history. Cooley identifies its work incorporating Genentech in 1976 as an early milestone, and its current practice serves biotechnology, pharmaceutical, medical-device, diagnostics and digital-health businesses. Licensing and collaboration agreements sit alongside financing and acquisition work, reflecting the importance of intellectual property and commercial partnerships in those industries.
Cooley also maintains litigation and regulatory practices rather than limiting its work to company-side transactions. Its overview identifies shareholder disputes, intellectual-property litigation, cybersecurity, healthcare and FDA matters among its capabilities. That combination connects the funding and development of innovative businesses with the regulatory obligations and disputes they encounter as they grow.
