Proceedings overview
There is one active ex parte reexamination proceeding on file for US Patent 11,284,475. This proceeding was granted, indicating that substantial new questions of patentability were raised for the challenged claims. This means the patent's claims are currently under reexamination, creating uncertainty regarding their validity.
90/015,103 — Unified Patents, LLC v. Wilus Institute of Standards and Technology, Inc.
- Type: Ex Parte Reexamination
- Filed: 2026-02-03
- Status: On March 10, 2026, the Central Reexamination Unit (CRU) granted the request, finding "substantial new questions of patentability" for the challenged claims of the '475 patent. The reexamination is currently pending.
- Judge panel: Not publicly available for ex parte reexaminations.
- Petition grounds: The request was filed by Unified Patents, LLC, as part of its efforts to address patents in the Wi-Fi 6 SEP space, implying challenges under 35 U.S.C. §§ 102 and/or 103 based on prior art.
- Institution decision: Granted on 2026-03-10. The CRU found "substantial new questions of patentability" for the challenged claims.
- Final Written Decision: Not yet issued, as the reexamination is currently pending.
- Settlement / termination: Not applicable; ex parte reexaminations are not inter partes proceedings and do not typically involve settlements between a petitioner and patent owner in the same way.
- Appeal: Not applicable at this stage.
- Defensive value: This active reexamination casts a shadow over the validity of the challenged claims. A defendant facing assertion of this patent could potentially leverage the ongoing reexamination to argue for a stay in district court proceedings or to negotiate a more favorable settlement, as the ultimate scope and validity of the claims are uncertain. If the reexamination results in claim cancellation or narrowing, it would significantly weaken any infringement allegations.
Strategic summary
Currently, the claims of US 11,284,475 are UNTESTED in the context of an inter partes AIA trial, but they are undergoing an ex parte reexamination. This reexamination was granted, meaning the USPTO found sufficient grounds to revisit the patentability of at least some claims. There are no claims that have been formally CANCELED or SUSTAINED through an inter partes proceeding, nor are there any estoppel implications from such trials. The fact that Unified Patents, a defensive aggregator, initiated the reexamination suggests a concerted effort to challenge patents in the Wi-Fi 6 SEP space, indicating a perceived vulnerability in the patent.
Recommended next steps
The ex parte reexamination (Control No. 90/015,103) is currently pending. It would be prudent to monitor the progress of this reexamination closely. The next major milestone will be the Examiner's Action, which will detail the grounds for unpatentability.
