Robert W. Cobbs is an Associate at Cohen Milstein and a member of the firm's Antitrust practice group.

Currently, Mr. Cobbs is litigating the following notable matters:

  • Anadarko Basin Oil and Gas Lease Antitrust Litigation (W.D. Okla.): Co-lead counsel for plaintiffs in class actions alleging that Chesapeake Energy, SandRidge Energy and a former executive of both companies conspired to rig bids for leases of land held by private landowners in parts of Oklahoma and Kansas.  This litigation follows the U.S. Department of Justice’s early 2016 indictment of a co-founder and former CEO of Chesapeake Energy for allegedly participating in this bid-rigging conspiracy. Plaintiffs allege that Defendants illegally conspired to stabilize and depress the price of royalty and bonus payments paid to landowners in the Anadarko Basin oil and gas province — a massive geological formation holding natural gas and oil deposits that includes large parts of Oklahoma and Kansas.  Pursuant to this conspiracy, Plaintiffs allege that Defendants communicated about and agreed on prices, allocated particular geographic areas between themselves, and rigged bids for leases of land, lowering acquisition prices across the region and thereby harming the proposed class of landowners. A motion for the preliminary approval of a $6.95 million settlement is pending before the court.
  • Interest Rate Swaps Antitrust Litigation (S.D.N.Y.): Cohen Milstein serves as co-lead counsel in a groundbreaking antitrust class action representing the Public School Teachers’ Pension and Retirement Fund of Chicago and a proposed buy-side investor class against numerous Wall Street investment banks.  The class alleges that the defendants conspired to prevent class members from trading IRS on modern electronic trading platforms and from trading with each other, all to protect the banks’ trading profits from inflated bid/ask spreads.
  • Stock Lending Antitrust Litigation (S.D.N.Y.):  Cohen Milstein serves as co-counsel in a groundbreaking antitrust class action alleging that major investment banks conspired to prevent the stock lending market from evolving by boycotting and interfering with various platforms and services designed to increase transparency and reduce costs in the stock lending market. On September 27, 2018, the court declined to grant Defendants’ motion to dismiss and ruled that investors may proceed with their class action.


Prior to joining Cohen Milstein, Mr. Cobbs clerked for the Hon. Pierre N. Leval, United States Court of Appeals for the Second Circuit; and for the Hon. J. Rodney Gilstrap, United States District Court for the Eastern District of Texas. 

Mr. Cobbs graduated from Amherst College with a B.A. in English and Russian, magna cum laude with distinction, and received his J.D. from Yale Law School. During law school, he served as a Notes Editor of the Yale Law Journal and as a Submissions Editor of the Yale Journal on Regulation.
