Inter Partes Review (“IPR”) was first made available via the America Invents Act (AIA) on September 16, 2012 as a counterpart to Post Grant Review. Accordingly, IPR is a procedure in which a third party may challenge the validity of patent claims based on existing prior art. Since its enactment, early statistics demonstrate that a staggering 87% success rate for the Petitioners to institute a trial with the Patent & Trial Appeal Board (“PTAB”) against the Patent Owners in the first year and equally favorable 76% success rate in the second year.
