Short Summary
ControlTec requests the PTAB Director to overturn the institution of an IPR on its expired ’847 patent, arguing that the patent’s long life creates strong settled expectations and that the cited Carter reference was already deemed non‑material. The petition seeks discretionary denial under § 314(a).
Detailed Summary
In a Request for Director Review (IPR2025‑00636), patent owner ControlTec, LLC asks the PTAB Director to vacate the September 30, 2025 decision that instituted an inter partes review of U.S. Patent 7,421,847. ControlTec contends that the patent, having been in force for 17‑18 years, generates strong settled expectations that merit discretionary denial of institution under 35 U.S.C. § 314(a). The petitioner further argues that the Carter reference cited by the petitioner was already found non‑material by the USPTO in a 2007 international search report, so there is no material error to justify review. The request cites numerous prior IPR decisions to illustrate a pattern of discretionary denials for older patents and urges the Director to follow that framework to avoid waste of Board resources.
