Bay Area Presence

Bay Area

At the heart of the Bay Area, with offices in Palo Alto and San Francisco, we are uniquely positioned to advise Northern California’s most prominent technology companies, private equity firms and financial institutions—as well as global leaders across industries. Since opening our Palo Alto office in 1999, we have grown in step with the region’s dynamic market and our clients’ evolving needs, a trajectory that spurred the launch of our San Francisco office in early 2026. Today, clients rely on our Bay Area team for deep technology-focused experience and the exceptional resources of a premier global law firm.

Top Lawyers in CA
Lawyers from the Firm’s Palo Alto and San Francisco offices have recently been named to the Daily Journal’s “Top 100 Lawyers in California,” “Top 20 Under 40 in California” and “Top 100 IP Lawyers in California” surveys

Augmented by the Firm’s network of 12 other offices worldwide, our Bay Area team guides clients on their most important matters across an array of areas, including:

We advise leading clients across the full spectrum of the technology sector—from artificial intelligence, data centers and digital infrastructure to software, semiconductors and telecom—and deliver cutting-edge counsel to innovators in banking, biotech, healthcare and consumer products. Our clients include both well-known players and emerging companies in these sectors, as well as investors, lenders and underwriters.
