The invalidation rate of patents in America Invents Act (AIA) proceedings, particularly inter partes reviews (IPRs), has been extremely high since the inception of the Patent Trial and Appeal Board (PTAB). Currently, a patent reaching a final written decision in an IPR will on average have 78% of its claims found invalid. Perhaps more surprising, when there is a final written decision, 70% of the time all challenged claims in the patent are found invalid.
