IPR2026-00244 — X Corp. v. Search And Share Technologies LLC

• Type: Inter Partes Review
• Filed: 2026-02-18
• Status: Pending (The proceeding is ongoing, and no institution decision or final written decision has been issued yet. The statutory deadline for an institution decision is typically six months from the petition's filing date, placing it around August 2026.)
• Judge panel: Not yet publicly available or assigned, as the proceeding is in its early stages before an institution decision.
• Petition grounds: Specific claims challenged, prior art, and statutory bases (e.g., § 102 / § 103) are not yet publicly detailed in the provided information or readily available from initial searches.
• Institution decision: Not yet issued.
• Final Written Decision: Not yet issued.
• Settlement / termination: No settlement or termination has been reported; the proceeding is active.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This active IPR indicates that the patentability of US10180952's claims is currently being contested. For a defendant, this means there is an ongoing challenge to the patent's validity, and the outcome could significantly impact any assertion built upon it. The patent is not yet "hardened" by surviving an IPR, nor have any claims been canceled.

Strategic summary

As of the current date, US Patent 10,180,952 has one active Inter Partes Review (IPR) proceeding, IPR2026-00244, which was filed on 2026-02-18 by X Corp. This proceeding is in its early stages and is currently listed as "Pending," meaning no institution decision has been rendered, and consequently, no claims have been canceled, sustained, or otherwise adjudicated by the PTAB. Therefore, all claims of US10180952 remain untested by a final PTAB decision.

The estoppel landscape has not yet been formed by this proceeding, as there is no final written decision. If IPR2026-00244 proceeds to a final written decision, the petitioner (X Corp.) and its privies would be estopped from raising invalidity grounds that were raised or reasonably could have been raised in the IPR for claims found patentable. However, until then, the full spectrum of prior-art grounds under § 102 and § 103 remains potentially available to other defendants. The presence of Unified Patents in the public record as associated with the IPR petitioner, "Unified Patents PTAB Data," suggests a potential pattern signal that a defensive aggregator is involved in challenging the patent.

Recommended next steps

The IPR2026-00244 proceeding is pending, meaning the PTAB has not yet decided whether to institute a trial. The institution decision deadline is approximately six months from the filing date, which would be around August 2026. Monitoring the PTAB E2E system for updates on IPR2026-00244 is crucial to track the institution decision. If the petition is instituted, further milestones will include a scheduling order, potential oral hearing, and the Final Written Decision due approximately one year from institution.
