About Katherine Lubin Benson

Katherine Lubin Benson is a partner in our San Francisco office specializing in securities and derivative suits and antitrust class actions.

Katherine currently represents court-appointed co-lead plaintiffs in shareholder derivative litigation against Fox Corporation’s directors and officers pending in Delaware Chancery Court, In re Fox Corporation Derivative Litigation, C.A. No. 2023-0418-BWD (Del. Ch.), and court-appointed co-lead plaintiff in securities fraud litigation against Block, Inc. and its executives pending in the Northern District of California, Gonsalves v. Block, Inc., et al., No. 5:25-cv-00642-NW (N.D. Cal.).

Her previous successful cases include a shareholder derivative action against The Boeing Company’s officers and directors . Katherine represented Co-Lead Plaintiffs the New York State Comptroller Thomas P. DiNapoli, as trustee of the New York State Common Retirement Fund, and the Fire and Police Pension Association of Colorado in the action alleging breach of fiduciary duty in connection with the board of directors’ oversight of the 737 MAX’s design and development. In February 2022, the Delaware Chancery Court approved a settlement comprised of a $237.5 million cash payment and extensive corporate governance reforms including a new board director, mandated director expertise, and an ombudsperson program.

Katherine was also a key member of the Lieff Cabraser team representing Co-Lead Plaintiff Fire and Police Pension Association of Colorado in a shareholder derivative action against Wells Fargo’s current and former officers and directors arising from the illicit sales practices scandal . The case settled for a $240 million cash payment and corporate governance reforms in April 2020. The settlement represents the largest insurer-funded derivative settlement in history.

Katherine is also an experienced antitrust litigator. Her recent antitrust successes include representing a class of hospitals, third-party payors, and uninsured persons in an antitrust class action against defendants Momenta Pharmaceuticals, Inc. and Sandoz Inc. for their alleged monopolization of enoxaparin, the generic version of the anti-coagulant blood clotting drug Lovenox. The settlement, totaling $120 million, is the second-largest indirect purchaser antitrust pharmaceutical settlement fund in history. Lieff Cabraser’s work on the case was recognized by the American Antitrust Institute, which honored the firm with the 2020 Outstanding Private Practice Antitrust Achievement award. Katherine was awarded AAI’s Outstanding Antitrust Litigation Achievement by a Young Lawyer award for her contributions to the case.

Katherine has served as a Co-Chair of the Lawyer Representative Committee to the Ninth Circuit Judicial Council, on the Board of Directors of the Bar Association of San Francisco, and on the Northern District Practice Program Board of Directors.

It is solely the responsibility of lawyers and law firms to ensure that any information they provide complies with all applicable laws and rules of professional conduct.

Lawyers.com Client Reviews

Martindale-Hubbell® Client Review Ratings™ display reviews submitted by individuals who have either hired or consulted the lawyers or law firms.

The Client Review Rating score is determined through the aggregation of validated responses. People who submit reviews are either individuals who consulted with the lawyer/law firm or who hired the lawyer/law firm and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be anyone who consults or hires a lawyer including in-house counsel, corporate executives, small business owners, and private individuals.

Martindale-Hubbell validates that a reviewer is a person with a valid email address. As part of the review process, respondents must affirm that they have had an initial consultation, are currently a client or have been a client of the lawyer or law firm identified, although Martindale-Hubbell cannot confirm the lawyer/client relationship as it is often confidential. The content of the responses is entirely from reviewers.

Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review. For more information on Martindale-Hubbell Client Review Ratings, please visit our Client Review Page

Martindale Peer Reviews

Martindale-Hubbell® Peer Review Ratings™ are the gold standard in attorney ratings, and have been for more than a century. These ratings indicate attorneys who are widely respected by their peers for their ethical standards and legal expertise in a specific area of practice.

The Martindale-Hubbell Peer Review Ratings process is the gold standard due to its objectivity and comprehensiveness. Lawyers solicited for peer reviews include both those selected by the attorney being reviewed and lawyers independently selected by Martindale-Hubbell. All reviewers are verified as attorneys through Martindale-Hubbell’s extensive attorney database. Only attorneys practicing at least three years and receiving a sufficient number of reviews from non-affiliated attorneys are eligible to receive a Rating.

What are the different Martindale-Hubbell Peer Review Ratings?*

• AV Preeminent®: The highest peer rating standard. This rating signifies that a large number of the lawyer’s peers rank him or her at the highest level of professional excellence for their legal knowledge, communication skills and ethical standards.

• Distinguished: An excellent rating for a lawyer with some experience. This rating indicates the attorney is widely respected by their peers for high professional achievement and ethical standards.

• Notable: This rating indicates that the lawyer has been recognized by a large number of their peers for strong ethical standards.

Lawyers who have received peer reviews after 2009 will display more detailed information, including practice areas, summary ratings, detailed numeric ratings and written feedback (if available). Details for individual reviews received before 2009 are not displayed.

Attorneys that receive reviews from their peers, but not a sufficient number to establish a Martindale-Hubbell Peer Review Rating, will have those reviews display on our websites.
