PAYING FOR DELAY : PHARMACEUTICAL PATENT SETTLEMENT AS A REGULATORY DESIGN PROBLEM

Over the past decade, drug makers have settled patent litigation by making large payments to potential rivals who, in turn, abandon suits that (if successful) would increase competition. Because such "pay-for-delay" settlements postpone the possibility of competitive entry, they have attracted the attention of antitrust enforcement authorities, courts, and commentators. Pay-for-delay settlements not only constitute a problem of immense practical importance in antitrust enforcement, but also pose a general dilemma about the proper balance between innovation and consumer access.
