Securities Litigation and Enforcement


Bruce G. Vanyo is co-head of Katten’s Securities Litigation and Enforcement practice and a member of the firm’s Board of Directors. Bruce maintains active practices in the firm’s New York and Century City offices. He has been called the “Dean of Securities Litigation” by many of his peers, and in his more than 37 years of practice has defended more major securities cases—well over 300—than many other lawyers in the country. Described as “very savvy in the shareholder litigation space” (Chambers USA), Bruce has represented some of the most prominent US companies, including The Boeing Company, Dell Computer, Hewlett Packard, Genentech and Bank of America, and has a strong record of success, winning more than 80% of his cases during the last 12 years while settling many others.

Bruce’s national practice consists of defending securities class actions and derivative litigation, representing clients before the Securities and Exchange Commission and assisting board committees in conducting internal investigations. His clients have come from industries including technology, life sciences, aviation, film, banking, mining, real estate and insurance, with headquarters in more than 20 different states as well as in several foreign countries.

Bruce has pioneered much of the securities law that has been favorable to defendants. When the technology industry was besieged by class actions, he was tapped to lead its securities litigation reform efforts, creating and drafting for Congress the pleading and safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Bruce has been described as a “towering figure in securities litigation,” having earned his reputation through a “remarkable skill set and an understated but authoritative demeanor” (Chambers USA). His colleagues in the defense bar have said publicly that he “comes up with new and novel arguments that other lawyers don’t see” and that “he doesn’t just think about the move he’s about to make and the likely response—he’s five steps ahead.” A prominent plaintiff’s lawyer publicly described Bruce as having “compassion not only for the CEO or CFO but also the employees of the company and concern about what the future of the company is going to be.”

Prior to joining Katten in 2006, Bruce was chairman of the Securities Litigation Group at Wilson Sonsini Goodrich & Rosati, where he founded the Litigation Department and served as its chairman from 1984 until 1996. Before that, Bruce handled securities fraud, antitrust and other complex litigation at McCutchen, Doyle, Brown & Enersen. He also served as a law clerk for Judge William H. Timbers of the US Court of Appeals for the Second Circuit.

Bruce Vanyo


Katten has a team that is ‘extremely responsive and just as knowledgeable‘. ‘Hands down my number one choice‘, remarks a client, who praises the firm’s ‘very pragmatic lawyers who understand business concerns, not just legal ones‘. Bruce Vanyo leads the practice from Los Angeles and has ‘a well-earned reputation as the godfather of securities litigation defense; his track record backs it up and he is unparalleled in his knowledge‘. Among the firm’s ‘extremely smart attorneys with strong intuition and a strategic mindset‘ are Chicago-based Michael Diver, LA-based Richard Zelichov (‘exceptional, very bright‘) and Christina Costley and, in New York, Jason Vigna. A highlight for the team was its work in securing the dismissal of four securities class actions consolidated in California on behalf of Natera, in which plaintiffs alleged that the company’s IPO offering documents were false and misleading.
