    When two of the three leading health plans in Massachusetts entered into merger discussions, Choate offered antitrust guidance to both parties.  Choate counseled Harvard Pilgrim Health Care and Tufts Health Plan, whose merger discussions made front-page news, on the issues that significant competitors face in mergers, including what information the competitors are permitted to share with one another.

    Choate litigators won dismissal of an antitrust class action in the first decision of its kind to apply vertical analysis in the area of private label retailing—a sector that has become increasingly important during the recession.  Class action lawyers attacked an agreement between high-tech manufacturer Hewlett-Packard and its leading retailer, Staples, alleging that the agreement had an unlawful impact on private label sales.  By demonstrating that the agreement was lawful because HP and Staples have a primarily vertical relationship, Choate’s original and creative defense won dismissal of the case.
