55 W. Monroe-Hearn

The firm has a longstanding and successful antitrust practice. Paul Slater in particular, who has taught antitrust law since the 1970s, specializes in antitrust law and devotes the majority of his time to antitrust matters. Other members of the firm are also regularly involved in its antitrust practice. 

While the list of antitrust matters we have handled is long, representative matters include the following:

  • In connection with the United Airlines bankruptcy, we were retained as special counsel to the Official Committee of Unsecured Creditors to investigate and prosecute alleged antitrust violations by a large group of public debt holders who controlled a significant percentage of planes in United’s fleet.
  • Our firm, along with a prominent Chicago patent firm, conducted a 4-week jury trial in which our client, M3 Systems, was accused of infringing two of C.R. Bard’s biopsy device patents and in which M3 countersued Bard for antitrust violations. The jury found for M3 Systems and against Bard on all counts, invalidated the patents at issue, and awarded M3 Systems several million dollars in antitrust damages. In 1999, the U.S. Supreme Court refused to review the Federal Circuit’s decision affirming the key patent and antitrust verdicts.
  • We were also counsel for plaintiffs in litigation involving claims that the plaintiffs had been thwarted in their efforts to acquire the Chicago Bulls of the National Basketball Association. After separate trials on liability and damages, the district court entered judgment for plaintiffs against all defendants.
