Companies are generally under no antitrust obligation to sell or license their products to, or provide their assets for use by, another company. As the Supreme Court explained almost a century ago, “as a general matter, the Sherman Act ‘does not restrict the long recognized right of [a] trader or manufacturer engaged in an entirely private business, freely to exercise [its] own independent discretion as to parties with whom [it] will deal.’”(1) Notwithstanding this general principle, courts, including the Supreme Court, have held that, under certain circumstances, the antitrust laws require a monopolist to deal with a rival.
