This casebook supplement is, in itself, a compendium of modern antitrust law. It presents or summarizes the ten U.S. Supreme Court antitrust cases decided since Trinko in 2004, which span almost all areas of antitrust law from resale price maintenance and tying to predatory buying, price-squeezing, joint ventures, the single-entity doctrine, extraterritorial jurisdiction, and the antitrust/regulation interface. As well, it presents contemporary merger and monopoly analysis, merger guideline revisions, the FTC's revitalization of its unfairness jurisdiction, and challenges to reverse payment pharmaceutical settlements, and it contains sufficient substantive excerpts from the European Microsoft case to allow an appreciation of the US/EU fault lines.
