David Reichenberg

Cozen O'Connor PC

As a leading antitrust litigator, David Reichenberg has become the cornerman top companies turn to when they need a skilled and passionate lawyer to champion their cause. This passion and skill has taken him to the highest levels of the field, successfully representing companies like Google, Netflix, Arista Networks, YouTube, and Twitter.

David’s defense of Netflix in a class action and his prosecution of a monopolization claim on behalf of Arista against Cisco Systems were both awarded the antitrust matters of the year by the Global Competition Review.

As a fierce advocate for his clients, he regularly advises Fortune 500 and other companies on the antitrust implications of potential business initiatives and has counseled and litigated on behalf of clients regarding all forms of unfair competition law, including intellectual property and trade secrets.

David has coordinated responses to investigations by the U.S. Department of Justice and Federal Trade Commission (on both the offensive and defensive sides), and he is active in the ABA Antitrust Section, currently serving as a vice chair on the Trial Practice Committee. David started his career at a leading antitrust boutique, focusing on merger clearance and litigation, which included the successful resolution of a CID in federal court.

David’s pro bono work is also a source of great pride, including representing individual litigants prosecuting civil rights claims in Federal Court.  Most recently, Dave was the first-chair on a trial team that secured a favorable jury verdict in the Eastern District of New York on a 1983 claim under the Fourth Amendment.

David has been recognized as a rising star by Super Lawyers, and he earned his undergraduate degree, with honors and distinction, from Cornell University. David earned his law degree from Fordham University School of Law, where he was the ADR editor of the Urban Law Journal, member of the Moot Court Board and received the top grade in EU Competition Law.
