“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.

“Given my determination in PGR2026-00003 as to the ’790 patent’s PGR eligibility, and because a patent cannot be both PGR eligible and IPR eligible at the same time, it is appropriate to vacate institution of this IPR.

RAI Strategic Holdings, Inc., IPR2020-01188, Paper 12 at 10–12 (PTAB Jan. 13, 2021); Paper 6, 3 n.2 (Samsung acknowledging that the ’790 patent is not eligible for simultaneous IPR and PGR).

“Today’s decision is consistent with Return Mail and—even if Return Mail reached the opposite conclusion—would be comfortably within the Office’s settled broad discretion in deciding whether to use its limited resources to institute IPR in any given case.

Feb. 13, 2026) (“[T]he Director has broad and protected discretion not to launch an IPR, even when the statutory pre-conditions are met.”). Indeed, as to the exercise of discretion, as I stated in the Memorandum, “the integrity of PTAB proceedings depends on knowing who is behind a petition—who funds it, directs it, and/or benefits from it. Any opacity in that chain of control invites exploitation, may facilitate technology transfer contrary to U.S. law, regulation, and interests, and serves only to undermine public confidence in the integrity of the patent system.” Memorandum 4.
