Some significant cases include:

  • Successfully secured a significant victory for a Fortune 500 publishing company with the full dismissal of a multi-district antitrust litigation in the Southern District of New York. The multi-district litigation consolidated a number of putative class action lawsuits alleging that our client, along with other textbook publishers and retailers, violated various federal and state antitrust laws through its implementation of Inclusive Access, a program authorized by federal regulation whereby students may be automatically billed for and automatically receive digital course materials selected by their professor.
  • Representing a contact lens manufacturer in the defense of an antitrust lawsuit brought by a discount retailer alleging anticompetitive pricing. Also defending our client in follow-on consumer class action suits that have arisen over the alleged price-fixing of contact lenses.

The plaintiffs are direct purchasers (wholesalers and chain stores) that alleged that our client conspired with other major chocolate manufacturers to fix the price of chocolate singles and “kings” in the U.S. between 2002 and 2007. The district court concluded that the record evidence led to the conclusion that “plaintiffs have adduced no evidence tending to exclude the possibility that defendants acted independently.” The Third Circuit affirmed the decision.
  • Successfully secured the dismissal of a multi-million dollar federal antitrust lawsuit against our client, a major pharmaceutical manufacturer. The Third Circuit Court of Appeals dismissed all antitrust claims against our client on the grounds that the plaintiff did not have the antitrust injury that is necessary for antitrust standing under Sections 1 and 2 of the Sherman Act.
  • Defended one of the major financial guaranty insurance companies in a series of antitrust claims brought by municipal bond issuers. In two separate groups of cases, the municipalities alleged wide-ranging conspiracies among insurers and others in both the sale of bond insurance and in the sale of municipal bond derivatives.
  • Representing a major financial institution in an antitrust lawsuit brought by another financial services company. In this follow-on suit to a Department of Justice case, the plaintiff sought damages for injuries allegedly suffered as a result of certain credit card rules.
