The Director denied the PGR petition and instituted no trial because Petitioner failed to identify Venator as a real party in interest within the statutory filing period.

“However, as I previously explained, RPIs are not limited to entities that are actually funding and controlling the proceeding but include entities that have the ability to control the proceeding. See Tianma, IPR2025-01579, Paper 12 at 9–10. Petitioner argues that its two owners do not have unilateral control of Petitioner. However, unilateral control is not the standard, and control of Petitioner is vested solely in its two owners as members of the Board of Directors. See Moyes Decl. ¶ 7. Accordingly, I am not persuaded that Venator and Lanxess do not have the ability to control” slip op. at 3

“Patent Owner further argues that Petitioner cannot correct its RPI listing because adding an RPI would require a new filing date that places the Petition outside the 9-month window for filing a PGR.
