Jake Walker

Jake Walker is a partner with offices in Boston and the Bay Area who focuses primarily on federal securities litigation throughout the country. He has helped recover over half a billion dollars on behalf of investors.

Jake is currently litigating on behalf of investors against Semtech (C.D. Cal.), Monolithic Power Systems (W.D. Wash.), and James Hardie (N.D. Ill.), among others. He was part of the team that secured a reversal in the U.S. Court of Appeals for the Eleventh Circuit in the NextEra securities litigation, which has since resulted in a settlement pending preliminary court approval (S.D. Fla.), and also helped reach a settlement in litigation against Biogen (D. Mass.), also pending preliminary court approval.

In the past several years, Jake has led litigation teams that recovered $40 million from Immunomedics (D.N.J.), $32.8 million from Snap, Inc. in litigation arising from its initial public offering (Cal. Sup. Ct.), $25 million from Lyft, Inc. in litigation arising from its IPO (N.D. Cal.), $25 million from the Tezos Foundation (N.D. Cal.) in litigation arising from the cryptocurrency's initial coin offering, $11 million in litigation against Mammoth Energy (W.D. Okla.) arising out of an indictment for bribery related to the company's business restoring power in Puerto Rico following Hurricane Maria, $8.5 million from Trevena (E.D. Pa.) arising out of the company's description of its interactions with the FDA, and $14.25 million from Tricida (N.D. Cal.) regarding its interactions with the FDA. Jake was also co-counsel in a case against Mattel, Inc. (C.D. Cal.) arising out of the company's need to restate earnings following a whistleblower letter, which resulted in a $98 million recovery for investors.

Jake has also obtained recoveries on behalf of investors in Gossamer Bio (S.D. Cal.), Bit Digital (S.D.N.Y.), EZCORP, Inc. (W.D. Tex.), Amicus Therapeutics (D.N.J.), Atossa Therapeutics (W.D. Wash.), Onyx Pharmaceuticals (Cal. Sup. Ct.), and Globalscape, Inc. (W.D. Tex.), among others. In addition to his securities litigation work, Jake assisted the firm in its work on the $14.7 billion settlement in the Volkswagen Diesel engine multi-district litigation, and has also led consumer litigation, including obtaining 100% recovery of damages for Massachusetts subscribers to newspapers published by Gatehouse Media, who were overcharged by the company.

Jake has been at the forefront of integrating AI and automation into the firm's securities practice, developing tools that monitor securities filings, market data, news, and judicial decisions to identify potential fraud and surface emerging developments more quickly than traditional review allows.

Prior to joining Block & Leviton in 2015, Jake was an associate at two of the country's top defense firms: Gibson Dunn in Palo Alto and Skadden, Arps in Boston. There, he represented boards of directors, corporate acquisition targets, and acquirers in litigation related to mergers and acquisitions. Jake represented defendants in litigation related to the $5.3 billion private equity acquisition of Del Monte Foods Company, as well as in litigation related to Intel's $7.7 billion acquisition of McAfee Inc. He has also represented numerous third parties, including various investment banks, in M&A litigation in California and Delaware courts.

Although Jake's career has centered on securities and corporate governance litigation, he also has significant experience representing several large technology companies, including in the defense of consumer class actions related to privacy and technology issues. He is a Certified Information Privacy Professional and has a deep understanding of technology and privacy issues. Jake has also represented companies in antitrust class actions and investigations, stockholder derivative actions, securities class actions, and in investigations before the F.T.C. and the Massachusetts Attorney General's Office.

Jake graduated from Babson College with a B.S. degree in Business Administration in 2001 and received his law degree, with honors, from the University of Michigan in 2010. He was named a "Rising Star" in securities litigation by Super Lawyers from 2016 to 2020 and has been selected to Super Lawyers from 2023 to 2026.

Outside the office, Jake has run six marathons over the past two years, including the Dopey Challenge at Disney World in 2026 — completing a 5K, 10K, Half Marathon, and Full Marathon over four consecutive days.
