Glenn concentrates his complex litigation practice principally in the areas of antitrust, telecommunications and technology policy. Glenn has nearly three decades of significant experience in high-tech litigation, with an emphasis on the impact of convergence and legal uncertainty between legacy industries and the new economy.

Glenn's core competence is in antitrust law, in which he has practiced since working at the Justice Department's Antitrust Division in connection with the AT&T divestiture. Among other things, he authored the influential February 1999 white paper by the Software & Information Industry Association proposing a divestiture remedy in the United States v. Microsoft antitrust case, and served as counsel for the Project to Promote Competition and Innovation in the Digital Age (ProComp) and the Computer & Communications Industry Association in connection with the government's prosecution and appeals. He has also participated in virtually all of the most important regulatory, judicial and legislative proceedings affecting telecommunications and the Internet for the past 30 years. For instance, Glenn was one of a handful of lawyers selected by the United States Court of Appeals for the Eighth Circuit in St. Louis to present oral argument in Iowa Utilities Board v. FCC, the first federal appeal of the FCC's local competition rules implementing the Telecommunications Act of 1996, and represented Web pioneer Netscape in 1997 in the first antitrust case involving the Internet market.

Glenn’s technology policy work has involved an array of subjects. He has represented major software and Internet-centric companies in matters involving domain name competition, standards, cybersecurity, privacy, intellectual property, broadband access, universal service, Internet regulation and spam. Glenn has served as lead trial and appellate counsel in numerous high-profile cases arising out of regulation and competition in network effects markets and on the interface between intellectual property and competition law. These include a landmark 2004 appellate reversal of the FCC's media concentration rules, the largest reported jury verdict in Maryland in 2005, and the first federal litigation challenging the regulated status of VoIP technology.

Glenn's clients have over the years comprised a veritable who's who roster of the IT industry leadership, including MCI, Netscape, Oracle, Google, Excite@Home, RIAA, Tellme, Echelon, EMusic, Travelocity, Winstar, Siebel, Sling Media and others.

Admitted to practice in the District of Columbia, Virginia and California, Glenn is a 1981 graduate of Columbia Law School, where he was notes and comments editor of the Columbia Law Review, and a cum laude graduate of Brandeis University.
