An inter partes review (IPR) is a post-grant procedure to challenge the validity of a patent at the US Patent Office before the Patent Trial and Appeal Board (PTAB). Anyone other than the patent owner can start an IPR and most are filed by an accused infringer. Initiating an IPR requires filing a request explaining why the challenged patent claims are invalid, supporting prior art documents, and written expert testimony with the PTAB. The patent owner files responsive arguments and expert testimony documents. There is no live testimony but the attorney for each side eventually argues before the PTAB. A successful IPR can result in the entire patent or some claims being cancelled.
