PTAB challenges

Proceedings overview

There is one active AIA trial proceeding on US Patent 11,950,105, which is currently in the "Trial Instituted" status. This means the patent's claims are actively being challenged, and the outcome will significantly impact the defensive posture for any defendant.

IPR2025-01206 — [[[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. Sai C. Manapragada

• Type: Inter Partes Review
• Filed: 2025-07-03
• Status: Trial Instituted (as of 2026-04-06). This means the PTAB has determined that there is a reasonable likelihood that at least one challenged claim is unpatentable, and a trial has commenced.
• Judge panel: Not publicly available yet.
• Petition grounds: Not publicly available yet, but IPRs typically challenge claims under 35 U.S.C. §§ 102 and/or 103 based on patents or printed publications.
• Institution decision: Instituted on 2026-04-06. The PTAB's reasoning for institution is not publicly detailed in the provided snippet but generally involves finding a reasonable likelihood that at least one challenged claim is unpatentable.
• Final Written Decision: Not yet issued, as the proceeding is active.
• Settlement / termination: No settlement or termination information is available.
• Appeal: No appeal information is available as a Final Written Decision has not been issued.
• Defensive value: This active IPR means that the patent's validity is currently under scrutiny. While no claims have been invalidated yet, the institution of trial indicates the petitioner has raised strong arguments. Defendants facing assertion should closely monitor this proceeding, as a Final Written Decision invalidating claims would significantly weaken the patent owner's position.

Strategic summary

Currently, all claims of US Patent 11,950,105 are UNTESTED by a Final Written Decision from the PTAB. IPR2025-01206 is actively challenging the patent, but a verdict on claim validity is pending.

The estoppel landscape will be shaped by the outcome of IPR2025-01206. If a Final Written Decision is issued, the petitioner (Samsung Electronics Co., Ltd. et al.) and their privies will be estopped from asserting invalidity grounds they raised or reasonably could have raised during the IPR. For other defendants, any prior art grounds not addressed or raised in this IPR could potentially still be available.

The filing of IPR2025-01206 by Samsung Electronics Co., Ltd. et al. indicates that at least one significant entity views the patent as a potential threat worth challenging. The "Trial Instituted" status suggests the PTAB found the petition to be of sufficient merit to proceed to trial. Unified Patents also filed this case (IPR2025-01206), which is a defensive aggregator and a signal that the patent is considered a potential issue for a broader industry.

Recommended next steps

If you are a defendant facing assertion of US Patent 11,950,105, it is critical to track the progress of IPR2025-01206. The PTAB has a statutory one-year deadline to issue a Final Written Decision from the date of institution (April 6, 2026), meaning an FWD is expected by April 6, 2027. Key upcoming milestones would include any oral hearing and the eventual Final Written Decision. You can monitor the progress of this case on the USPTO PTAB E2E portal.
