PTAB Trials


The America Invents Act (AIA) created several proceedings for challenging patent validity at the U.S. Patent and Trademark Office. These proceedings, which are held before the Patent Trial and Appeal Board (PTAB), include inter partes review (IPR), post‑grant review (PGR), and the transitional program for covered business method patents (CBM).

MBHB attorneys are uniquely qualified to handle proceedings before the PTAB. Indeed, not only do our attorneys have extensive litigation experience and comprehensive knowledge of the underlying technologies, but we also interact with the U.S. Patent and Trademark Office on a daily basis. Moreover, we have decades of experience handling cases before the PTAB and its predecessor, the Board of Patent Appeals and Interferences. With this specialized blend of skills, we know exactly what it takes to represent clients in all aspects of PTAB proceedings— from pre-institution strategy through oral hearing (and beyond).

Our attorneys are also dedicated to monitoring the latest developments at the PTAB, which puts us in the best possible position to educate and advise our clients on this quick-paced alternative to district court patent litigation. The News & Events and Publications tabs contain presentations and articles we have authored on topics relating to PTAB litigations.
