Jeffrey Blumenfeld is a partner at Crowell & Moring, specializing in antitrust and complex litigation, including cartel investigations and trials, competition issues facing technology companies, and the intersection of intellectual property and competition law.

Jeffrey has significant antitrust experience in counseling, litigation and trial of both civil and criminal antitrust matters. He has defended corporations and individuals in criminal price-fixing investigations and trials, and has represented both plaintiffs and defendants in monopolization and attempted monopolization cases, as well as in mergers and acquisitions.

Jeffrey's years of trial experience in complex civil and criminal cases - as an Assistant United States Attorney, at the Antitrust Division, and in private practice - equip him to meet clients' needs when trial is the best option.

A long-time trial attorney in the Antitrust Division of the U.S. Department of Justice, Jeffrey served as chief of the Department's trial staff in United States v. AT&T and also served as assistant chief of the Special Regulated Industries Section.

Jeffrey has extensive legal experience with technology-driven issues, including the overlap among technology, intellectual property and competitive issues. Jeffrey serves as antitrust counsel to Via Licensing, the nation's leading administrator of IP licensing programs, and is counsel to the Open Patent Alliance, which was formed to accelerate the widespread adoption and deployment of WiMAX technology and products. In the technology space, Jeffrey works closely with senior management - including CEOs, CFOs, marketing, sales and strategic business units.

In addition to serving on the Boards of Directors of several client companies, Jeffrey served as Chief Legal Officer and General Counsel of Rhythms NetConnections Inc., a broadband network facilities and services provider, from its founding in mid-1997 to March, 2001.

Based on his expertise in competition and strategy in technology industries, Jeffrey was chosen by former Assistant Attorney General for Antitrust Anne Bingaman, as well as by her successor, Joel Klein, to serve as special counsel to the Antitrust Division on a number of high-profile antitrust investigations, including the investigations that became US v Visa and MasterCard, and US v Microsoft.

His broad experience enables Jeffrey to consistently represent his clients across multiple forums, including in federal and state courts, at the Department of Justice, before the Federal Communications Commission, and in Congress. Jeffrey is also one of the most experienced regulatory litigators, and has litigated and tried matters at the FCC and at state commissions across the country, ranging from complex engineering and technology issues, to economic, costing and pricing issues, to competitive conduct issues.

Adjunct Professor at Georgetown University Law Center, offering courses in Communications Law and Trial Practice, Jeffrey is also a regular speaker at industry conferences, as well as at meetings of state and federal communications regulators.

A cum laude graduate of Brown University in Philosophy of Religion, Jeffrey earned his J.D. from the University of Pennsylvania.
