Patent settlements between rivals restrain competition in many different ways. Antitrust requires them to be "proportional" in that their anti-competitive effects are commensurate with the firms' expectations about (counterfactual) patent litigation. Because these expectations are private and...

Patent settlements between rivals restrain competition in many different ways. Antitrust requires that their anticompetitive effects are reasonably commensurate with the firms’ expectations about (counterfactual) patent litigation. Because these expectations are private and non-verifiable,...

One of the most intractable competition issues for the European Commission (the “Commission”) over the last ten years has been to define the circumstances in which the licensing conduct or litigation strategy of a standard-essential patent (often referred to as “SEP”) holders amount to...

Courts are rarely asked to judge beauty. Such a subjective practice would normally be anathema to the ideal of objective legal standards. However, one area of federal law has a long tradition of explicitly requiring courts to make aesthetic decisions: the law of design. New designs may be...

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 that the patent is actually valid and infringed, and...

A generic drug maker that has been sued for infringing a patent on a branded drug will sometimes promise, as part of an agreement settling the litigation, to delay selling its drug until as late as the expiration of the patent term. I adapt the standard optimal patent term model to determine...

Patent holdup occurs when a patent holder extracts higher royalties ex post (after the payor has committed to use of the patented technology) than it could have negotiated ex ante, where the difference is not explained by an increase in the technology's value. To date, the literature principally...

The Patent Trial and Appeal Board (PTAB) is a recently-formed division of the Patent Office in which patents can be challenged as invalid, and which differs from federal courts in a number of respects. We investigate whether monopolist-patentees and their prospective rivals are using the PTAB...

Injunctions for standard essential patents (SEPs) — that is, patents that are essential to practice an industry standard — have been at the center of the antitrust debate for more than a decade. In July 2015, the Court of Justice of the European Union (CJEU) issued its long awaited decision...
