Inter partes review (“IPR”) has been popularly adopted and used as a strategy for invalidating patent claims due to its compact and expedited process. The Board is required to render an institution decision within 3 months of preliminary briefings on issues of claim patentability and a final decision within 12 months of any instituted proceeding. Such a time frame allows both a petitioner and a patent owner to reach a conclusion on the patentability dispute. Further, the expedited schedule allows each party to understand its relative strength of argument, leading to a settlement within a relatively short period of time as compared to a proceeding before a federal district courts, thereby saving time and expense in the patent dispute.
