In Patent Inflation, I argued that the asymmetry in Federal Circuit review of Patent and Trademark Office (PTO) decisions would lead over time to inflation in the boundaries defining what inventions are patentable. In short essays, Professor Arti Rai and Lisa Ouellette have offered valuable commentary, including both qualitative (Rai) and quantitative (Ouellette) evidence bearing on the question of inflation. In this brief response, I explain how their evidence is consistent with—indeed, bolsters—the theory presented in Patent Inflation. Direct Federal Circuit reversals of PTO decisions make up only a small portion of that court’s caseload. But those cases have exerted outsized influence on the development of the law, particularly across a number of the most significant patent doctrines. This is just as Patent Inflation would predict.

Jonathan Masur’s argument regarding “Patent Inflation” rests on the assumption that PTO behavior is determined almost entirely by a desire to avoid reversal of its patent denials by the Federal Circuit. Although the U.S. Patent and Trademark Office (PTO) is certainly a weak agency over which the Federal Circuit has considerable power, Masur overestimates the extent to which high-level PTO administrators are concerned about Federal Circuit reversals and underestimates institutional influences that are likely to operate in a deflationary direction. The PTO is influenced not only by the Federal Circuit and other inflationary forces, but also by executive branch actors, industry players, and workload concerns that push in a deflationary direction.

In Prods and Pleas, Benjamin Ewing and Douglas Kysar claim that the American legal system needs to adopt novel solutions to deal with the question of global warming. In this Essay, I start from the premise that some form of legal response to global warming is appropriate, but then conclude that the traditional allocation of responsibility between private rights of action (for large concentrated harms) and direct government administrative action (for diffuse harms) remains the proper approach. In light of the worldwide nature of the problem, the only domestic responses to this issue should be through coordinated action at the federal level. Accordingly, I agree with the Supreme Court’s decision in American Electric Power Co. v. Connecticut and conclude further that the comprehensive powers lodged in the Environmental Protection Agency should not only block private rights of action under federal law, but under state law as well.
