Debevoise Taps Elite Litigator Josh Lerner Amidst Tech Trade Secret Surge

SAN FRANCISCO, CA – July 01, 2026 – International law firm Debevoise & Plimpton LLP has announced a significant addition to its West Coast team, welcoming Josh Lerner as a partner in the Commercial Litigation Group based in its San Francisco office. A senior trial lawyer with a formidable reputation in high-stakes disputes, Mr. Lerner's arrival signals a strategic deepening of the firm's capabilities in the epicenter of the global technology and life sciences industries.

Mr. Lerner will focus on complex commercial and intellectual property (IP) litigation, bringing his extensive courtroom experience to a legal market grappling with an unprecedented rise in enterprise-defining disputes. The move is seen as a direct response to the escalating demand from tech and life sciences clients for elite counsel capable of navigating the intricate and often perilous landscape of trade secrets and IP law.

A Strategic Response to a Shifting Legal Landscape

Lerner’s arrival comes at a critical juncture for West Coast industries. California has long been the nation's leader in trade secrets litigation, a trend that has only accelerated. In recent years, federal trade secret filings have surged to their highest levels in over a decade, with California's courts managing the lion's share of this caseload. This litigation boom is driven by a confluence of factors, including intense competition, high employee mobility, and the proliferation of disruptive technologies like artificial intelligence (AI), which creates new frontiers for IP protection and theft.

As companies race to protect their most valuable proprietary information, the need for battle-tested litigators has never been greater. "Technology companies are at the center of a broader rise in trade secrets and commercial disputes across industries, often on compressed timelines and headed toward trial," said Debevoise's Presiding Partner Peter Furci. The firm's strategic recruitment of Lerner is a clear acknowledgment of this reality, positioning it to offer clients the sophisticated, trial-ready representation required in this high-stakes environment.

A Battle-Tested Litigator for High-Stakes Disputes

Josh Lerner is widely recognized as a seasoned first-chair trial lawyer who has built a career representing market-leading companies in their most critical matters. Before joining Debevoise, he served as partner and Co-Chair of the trade secrets practice at another prominent international law firm, where he managed some of the largest trade secret cases in the country.

His experience is both deep and varied. It includes a pivotal in-house role as senior litigation counsel at biotech giant Genentech, giving him a rare client-side perspective on corporate objectives and risk management. This blend of in-house insight and private practice prowess is highly valued by clients, who have praised his ability to deliver "common sense advice informed by deep subject matter knowledge." Mr. Lerner's practice covers the full spectrum of complex disputes, from IP and business torts to founder conflicts and sensitive internal investigations involving data and intellectual property.

Debevoise leadership lauded his credentials. In a joint statement, Maeve O’Connor and Michael Schaper, Co-Chairs of the Commercial Litigation Group, said, "Josh is a seasoned first-chair trial lawyer with deep experience advising market-leading companies on business-critical disputes. He is a terrific addition to our top-notch commercial litigation practice, and we look forward to working with him on the most challenging matters for the most innovative clients, both on the West Coast and across the country."

Reflecting on his move, Mr. Lerner noted the unique opportunity presented by the firm's platform. "Debevoise has a strong track record handling complex disputes for technology clients," he said. "The firm's litigation platform and client base create an opportunity to build on and expand that work on the West Coast, including in matters where trial readiness is critical."

Bolstering a Growing West Coast Powerhouse

Lerner's hire is not an isolated event but the latest in a series of strategic moves that underscore Debevoise's commitment to the West Coast. The firm launched its San Francisco office in 2021 with the express purpose of providing on-the-ground support for its growing roster of technology and private investment clients in the region. Since then, the office has experienced a period of sustained and deliberate growth.

The firm has consistently added top-tier litigation talent, including partners specializing in white-collar defense, IP litigation, and complex commercial disputes, creating a multi-faceted team capable of handling a wide array of sophisticated matters. This strategic investment in personnel has been matched by a physical one; the firm recently announced it was nearly doubling its San Francisco office footprint, a clear signal of robust client demand and a long-term commitment to the Bay Area market.

Mr. Furci underscored this strategy, noting the "strong demand among our Bay Area clients, especially in the technology and asset management industries, for representation on a broad range of complex litigation matters." By adding a litigator of Lerner's caliber, the firm not only meets existing client needs but also enhances its competitive posture in a fiercely contested market.

Navigating the Competitive Bay Area Legal Market

The Bay Area is home to a dense ecosystem of legal talent, including specialized IP boutiques and global law firms all vying for a piece of the lucrative tech and life sciences litigation market. In this environment, the recruitment of elite partners like Josh Lerner is a key differentiator. His move highlights the ongoing "talent wars" where firms compete to attract seasoned professionals with proven track records and deep sector expertise.

With this addition, Debevoise reinforces its standing as a premier destination for complex litigation. Mr. Furci stated that, "Josh brings the battle-tested courtroom experience and sector focus clients need in that environment and further strengthens our already robust litigation platform in San Francisco." This strategic hire empowers the firm to compete for and win the most challenging, high-value disputes, solidifying its reputation as a litigation powerhouse on the West Coast and across the country.
