As set forth in part 1 of this article, the question of how a real party in interest (RPI) to an inter partes review (IPR) is determined has presented challenges and uncertainties for litigants. The RPI analysis is critical for both petitioners and patent owners, as a failure to identify an RPI may result in denial of institution, termination of an instituted trial, or severe estoppel consequences for a petitioner (and its RPIs and privies) in a parallel district court or International Trade Commission (ITC) litigation.
Whether a non-petitioner party is an RPI is a highly fact-dependent question and, accordingly, the RPI determination varies with the specific facts in each case.

The PTAB decisions to date have touched on different categories of entity situations, including:
