The United States Department of Justice confirmed today that the Penguin group has made a settlement offer in New York District Court to end its ongoing e-book price fixing antitrust investigation. If accepted by the Department of Justice and the judge, only Apple and Macmillan will remain as defendants in the suit. Under the agreement's terms, Penguin must cease doing business with any e-book seller it is currently doing business with which does include Apple. The publisher will also be prohibited from signing deals with distributors that limit discounts for two years.
