In view of the billions of dollars and enormous effort that might otherwise be wasted, the public interest will be best served if the Supreme Court of the United States reaches the merits of the present challenges to the Patient Protection and Affordable Care Act (ACA) during its October 2011 Term. Potentially standing in the way, however, is the federal Tax Anti-Injunction Act (TAIA), which bars any “suit for the purpose of restraining the assessment or collection of any tax.” The dispute to date has mostly turned on the fraught and complex question of whether the ACA’s exaction for being uninsured qualifies as a “tax” for purposes of the TAIA. We argue that the Supreme Court need not resolve this issue because the TAIA does not apply for a distinct reason: the present challenges to the ACA do not have “the purpose” of restraining tax assessment or collection. In order for the TAIA not to bar refund suits, the TAIA must be read to bar suits with the immediate purpose of restraining tax assessment or collection. The present challenges do not have such an immediate purpose because the very authority to assess or collect will not exist until long after the litigation is concluded. Among other virtues, this resolution of the TAIA question does not predetermine whether the tax power justifies the minimum coverage provision.

**This is the sur-reply to a series of responses to Jonathan Masur's recent article, Patent Inflation, which appeared in the December issue of YLJ. For Professor Arti Rai's response, see here. For Lisa Ouellette's response, see here.**

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.
