We also have leading practices in the areas of patent litigation, tax, investment management, and labor and employment.

Our clients include FORTUNE 50 companies to start-ups and everything in between. We represent pharmaceutical and biotech companies; computer, electronics, software, e-commerce, and technology companies; banking, insurance, and financial services institutions; industrial, food, cosmetic, and consumer product companies; healthcare providers and hospitality companies; hedge, private equity, and venture capital funds; and professional sports teams, entertainment, and media companies.

Our attorneys are regularly recognized by Chambers and Best Lawyers, and several have appeared on the Daily Journal's "Top Labor & Employment Attorneys," "Top 100 Attorneys," "Top Women Attorneys," and "Top Intellectual Property Attorneys" lists. In addition, Managing Intellectual Property and LMG Life Sciences have recently recognized attorneys from the San Francisco office in their publications.

Like our colleagues across the firm, we are passionate about community involvement. Our attorneys are actively involved in numerous pro bono matters, including representing victims of domestic violence and those seeking asylum, challenging capital punishment in California, supporting the fight for marriage equality, and protecting the rights of the homeless.
