Six U.S. manufacturers of broad-spectrum antibiotics derived a large percentage of their sales from overseas markets, including India, Iran, the Philippines, Spain, the Republic of Korea, Germany, Colombia, and Kuwait. The manufacturers agreed to a common plan of marketing, whereby territories were divided and prices for products were set. The members of the plan also agreed not to grant foreign producers licenses to the manufacturing technology of any of their ‘‘big money’’ drugs. May the above foreign countries recover treble damages for violation of the U.S. antitrust laws? Why?
