Boies Schiller Flexner LLP announced today that it has expanded in California with the hire of Margaux Poueymirou as partner in the firm’s San Francisco office.
Margaux is an experienced litigator who has represented plaintiffs and defendants in complex litigation disputes involving antitrust, intellectual property, and AI issues. Her work on cases over the use of copyrighted works to train generative AI models has given her a deep understanding of the technical aspects of how AI platforms are developed.
“We’ve known Margaux for several years and have had the opportunity to see her talent first-hand. It’s clear she brings a trial lawyer’s mentality and tenacity in representing clients in complex, high-stakes litigation in the technology sector,” said San Francisco office leader Maxwell Pritt, who heads the firm’s work in Kadrey v. Meta Platforms, Tremblay v. OpenAI, and Doe v. GitHub with Margaux. “She’ll be an excellent addition to our San Francisco office, and I’m looking forward to continuing to work with her and the rest of the attorney team, along with our co-counsel, on these cutting-edge cases.”
Margaux joins from the Joseph Saveri Law Firm where she played a key role representing software developers, authors, and other plaintiffs in pioneering AI copyright cases against technology companies. She also has extensive experience in antitrust litigation, primarily representing opt-out plaintiffs in complex matters involving anticompetitive and fraudulent practices in the healthcare and pharmaceutical sectors.
“In joining BSF, I was particularly drawn to the firm’s willingness to handle cases on both sides of the v,” Poueymirou said. “As AI increasingly transforms every industry, plaintiffs and defendants alike will need to navigate an evolving landscape. Today’s AI-related litigation will define the contours of AI and copyright law, but antitrust, privacy, and other commercial issues are likely to be implicated in future litigation. It’s an exciting time to be working in this area, and I’m looking forward to continuing to grow my practice.”
An inaugural public interest fellow at the University of California, Irvine School of Law, Poueymirou regularly dedicates her time to pro bono work. She has drafted amicus briefs on gun regulation and successfully argued compassionate release motions for incarcerated individuals under the First Step Act.
“We’re excited to add Margaux to our growing presence in California,” said BSF Chairman and Managing Partner Matthew L. Schwartz. “It’s obvious that AI is creating change on a drastic scale across industries, and Margaux’s expertise will be valuable to clients as they navigate the inevitable regulatory changes and litigation challenges that arise.”
