Patent Trial and Appeal Board (PTAB) performance benchmarks for dispositions, pendency, inventory, and other tracking measures.


Under Construction: PTAB is migrating to a new statistics format for AIA trials. We are moving all of our outcome statistics into a new quarterly “Outcome Roundup” format that includes outcome information on a by-petition, by-patent, and by-claim basis. We will continue publishing non-outcome trial statistics on a monthly basis. In addition, we now provide end of year outcome statistics for fiscal year 2019 for AIA trials below, and expect to provide the same for fiscal year 2020 soon.
