Solving the Patent Settlement Puzzle

Courts and commentators are sharply divided about how to assess reverse payment patent settlements under antitrust law.   The essential problem is that a PTO-issued patent provides only a probabilistic indication that courts would hold the patent is actually valid and infringed, and parties have incentives to structure reverse payment settlements to exclude entry for longer than this patent probability would merit.   Some favor comparing the settlement exclusion period to the expected litigation exclusion period, but this requires difficult case-by-case assessments of the probabilities of patent victory.   Others instead favor a formal scope of patent test that allows such settlements for non-sham patents if the settlement does not delay entry beyond the patent term, preclude non-infringing products, or delay non-settling entrants.   However, the formal scope of patent test excludes entry for longer than merited by the patent strength, and it provides no solution when there is either a significant dispute about infringement or a bottleneck issue delaying other entrants.   This paper provides a way out of this dilemma.  It proves that when the reverse payment amount exceeds the patent holder’s anticipated litigation costs, then under standard conditions the settlement will, according to the patent holder’s own probability estimate, exclude entry for longer than both the expected litigation exclusion period and the optimal patent exclusion period, which both harms consumer welfare and undermines optimal innovation incentives.   Further, whenever a reverse payment is necessary for settlement, it will also have those same anticompetitive effects according to the entrant’s probability estimate.  This proof thus provides an easily administrable way to determine when a reverse payment settlement is necessarily anticompetitive, without requiring any inquiry into the patent merits.  We also show that, contrary to conventional wisdom, patent settlements without any reverse payment usually (but not always) exceed both the expected litigation exclusion period and the optimal patent exclusion period, and we suggest a procedural solution to resolve such cases.

Setting Examples, Not Settling

Ross MacDonald

91 Texas L. Rev. 419

PDF Document

In this Note, Mr. MacDonald argues that the Securities and Exchange Commission must structurally rethink the way it enforces securities laws because the current system is radically inadequate.   Part II discusses the history of this system.  Part III details the incentives behind the settlement regime, and Part IV documents its rabid and uncompromising failures on both a theoretical and empirical level.  Part V suggests two solutions bringing more cases to trial and imposing individual, rather than corporate, liability as methods for bringing securities laws enforcement back to deterrence equilibrium, where the harm of violating the laws actually compares to the expected costs of those violations.   Ross MacDonald argues that only at such an equilibrium can the public reasonably expect to see the number of financial frauds decrease to an acceptable level.

Blowing the Whistle on Civil Rights

Ralph C. Mayrell

91 Texas L. Rev. 449

PDF Document

In this Note, Mr. Mayrell sets out to explain the legal theory through which civil rights litigators can effectively litigate claims against local government discriminators using the False Claims Act (FCA).   Part I briefly outlines the scheme of antidiscrimination laws and regulations that are potentially enforceable under the FCA and their limitations.   Part II lays out the legal theory of how an antidiscrimination action could form the basis of an FCA claim and provides recent examples of courts favorably reacting to plaintiffs’ use of the FCA in civil rights suits.   Part III briefly proposes that agencies use their contracting flexibility to add relevant constitutional requirements.   Part IV discusses the potential legal and policy hazards of using the FCA to increase the liability of local governments for civil rights violations.
