PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US patent 11368911. The proceeding was an Inter Partes Review (IPR) which terminated due to settlement, meaning no claims were formally invalidated or sustained by the Patent Trial and Appeal Board (PTAB). This leaves the patent's claims untested by the PTAB on the merits, offering a different defensive posture than one with adjudicated claims.

IPR2025-01189 — [[[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) v. Hannibal IP LLC

• Type: Inter Partes Review
• Filed: 2025-07-11
• Status: Terminated-Settled. The proceeding concluded without a final written decision on the merits due to a settlement between the parties.
• Judge panel: Information regarding the specific Administrative Patent Judges (APJ) panel for this proceeding is not publicly available in the provided sources at this time.
• Petition grounds: The petition was filed by Samsung Electronics Co., Ltd. et al. against patent 11368911. Specific details of the challenged claims, prior art, and statutory bases (§ 102 / § 103 / § 112) of the petition are not available in the provided context or readily discoverable through general public searches for a settled IPR without a published institution decision or final written decision.
• Institution decision: Details regarding whether the IPR was instituted, denied, or partially instituted are not publicly available due to the settlement.
• Final Written Decision: Not issued, as the proceeding terminated due to settlement.
• Settlement / termination: The proceeding was last modified on 2026-04-17 with a status of "Terminated-Settled". The specific terms of the settlement are confidential between Samsung Electronics Co., Ltd. et al. and Hannibal IP LLC.
• Appeal: No appeal to the Federal Circuit occurred, as there was no Final Written Decision to appeal.
• Defensive value: Since this IPR was settled, no claims of US11368911 were invalidated by the PTAB. For a defendant facing assertion of this patent, this means the claims have not been challenged and found unpatentable in an IPR setting. However, the settlement itself could indicate a strategic decision by the patent owner or petitioner, which may or may not reflect on the underlying patentability of the claims. The claims remain untested in this specific IPR.

Strategic summary

All claims of US11368911 remain UNTESTED by the PTAB on the merits. The single IPR filed, IPR2025-01189, terminated due to a settlement, meaning the PTAB did not issue a decision on the patentability of any claims. Therefore, the patent has not been narrowed through IPR.

Regarding the estoppel landscape, § 315(e)(2) bars the petitioner (Samsung Electronics Co., Ltd. et al.) and their privies from raising any ground they raised or reasonably could have raised during IPR2025-01189. For other defendants being asserted against, this specific IPR does not create estoppel against them, and the prior-art grounds that could have been used against this patent remain available for new challenges.

The involvement of Samsung Electronics Co., Ltd. as a petitioner suggests that the patent's technology is relevant to major players in the wireless communication space. The "Terminated-Settled" status for IPR2025-01189 is a common outcome in PTAB proceedings and often occurs when the parties reach a broader licensing agreement or resolution that encompasses the patent.

Recommended next steps
