Antitrust law has long been a centerpiece of Glenn Manishin’s legal career, in which he is the only attorney to have appeared as counsel-of-record in the most significant antitrust cases spanning two generations — the US v. AT&T and US v. Microsoft monopolization cases. He was principal decree (MFJ) counsel for MCI, McCaw Cellular and other competitors before the late District Judge Harold Greene for more than a decade. Glenn then authored a landmark February 1999 White Paper by the Software & Information Industry Association proposing a divestiture remedy for the Microsoft antitrust litigation. He served as counsel for ProComp (The Project to Promote Competition in the Digital Age) and the Computer & Communications Industry Association — along with former Judges Robert Bork and Kenneth Starr — in the Tunney Act and subsequent federal appellate challenge to the government’s 2002 Microsoft settlement consent decree. Glenn has more recently handled a series of ground-breaking antitrust cases arising out of the relationship between regulation and competition in network effects industries and the interface between IP and antitrust law. In the M&A arena, he has secured “early termination” of pre-merger antitrust review from both DOJ and FTC, without a “second request,” in more than $100B worth of M&A deals involving cable television set-top boxes, automobile fleet transportation, hospital-physician practice acquisitions and other markets, with coordinated international merger clearances in Russia, China, Canada, Brazil, Mexico and other countries.
