Jake Walker is a partner who focuses primarily on federal securities litigation throughout the country. He has been named a “Rising Star” in securities litigation since 2016 by Super Lawyers.

Among other cases, Jake is actively litigating on behalf of investors against Immunomedics, Inc. (D.

Jake is also instrumental in the appeal to the First Circuit on behalf of investors in Keryx Biopharmaceuticals (1st Cir.) arising from the company’s misstatements concerning a key supplier.

In the past year, Jake has led litigation teams that recovered $32.8 million from Snap, Inc. in litigation arising from its initial public offering (Cal. Sup.

Jake has also obtained recoveries on behalf of investors in 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 also 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.

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.

He has also represented numerous third parties, including various investment banks, in M&A litigation in California and Delaware courts.

While Jake’s ten-year career has centered on securities and corporate governance litigation, Jake 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.
