What Coblentz Patch Duffy & Bass LLP does
Coblentz Patch Duffy & Bass LLP is a San Francisco-based limited liability partnership founded in 1890 that operates as a mid-sized, full-service independent law firm. It fields 170+ attorneys organized across 10 practice areas — Corporate, Data Privacy & Cybersecurity, Employment, Exempt Organizations, Family Wealth, Intellectual Property, Litigation, Real Estate, Tax, and White Collar Defense & Investigations — and serves enterprise, institutional, and high-net-worth clients in 15+ industries including sports (San Francisco 49ers), healthcare (California Pacific Medical Center / Sutter Health), real estate development (Tejon Ranch), cultural/educational nonprofits (California Academy of Sciences, Exploratorium), telecommunications (DISH Network), aviation (Jackson Square Aviation, Pegasus Aviation), and artificial intelligence. The firm differentiates itself by having survived as an independent Bay Area mid-market firm while many competitors consolidated into national platforms, with deep regional relationships and TAGLaw membership providing international referral coverage.
The firm generates revenue through traditional professional-services billing: hourly attorney rates scaled by seniority, practice area, and matter complexity, with select fixed-fee arrangements on routine matters and multi-year client engagements common. Its go-to-market is relationship-led and partner-driven, supported by thought-leadership channels including the "Unfamiliar Terrain" blog, Law360 publications, ULI/Bisnow speaking engagements, and sustained analyst recognition (Legal 500 Elite, Best Lawyers, Benchmark Litigation, Super Lawyers). The firm is led by Managing Partner Sara Finigan (since 2025, previously Co-Managing Partner since April 2018) and operates from a single San Francisco headquarters at One Montgomery Street.
Firmographics: founded 1890; private partnership; 101-250 total employees per disclosure; 170+ attorneys; sole office in San Francisco, California; senior leadership transition completed in 2025; legal services positioned as premium Bay Area counsel for sophisticated matters (e.g., $14.2 million jury verdict, $500 million aviation-financing matters, U.S. Supreme Court amicus activity).
