Winning Strategies at the PTAB, Part II: Common Pitfalls That Patent Owners Should Avoid

Part I of this article discussed how the Patent Trial and Appeal Board (PTAB) is a very different tribunal from district courts. It is a venue where fact and issues of law are decided by technical specialists, who are also highly trained in patent law, instead of lay judges and juries. It also discussed the formidable challenge presented to patent owners by the PTAB, where inter partes review (IPR) institution rates are about 67% and final written decisions find all challenged claims unpatentable up to 70% of the time. Part II will discuss strategies that give patent owners a better chance at successfully navigating the IPR process.

Winning Strategies at the PTAB, Part I: Bring Your Game

Litigating the validity of claims in an inter partes review (IPR) at the Patent Trial and Appeal Board (PTAB) is vastly different from litigating validity in district court. PTAB judges are scientists and engineers, and they are also patent attorneys. They have significant technical training, and most have advanced technical degrees. You can assume they know substantive patent law cold. PTAB judges represent a very different audience from a lay judge or a jury in district court.
