PTAB challenges

Proceedings overview

One AIA trial proceeding has been filed against US patent 11671702, which resulted in a discretionary denial. This gives a defendant a mixed defensive posture, as the patent claims were not tested on the merits, but the petitioner failed to institute a review.

IPR2025-01520 — [[[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. Snapaid Ltd.

• Type: Inter Partes Review
• Filed: 2025-09-05
• Status: Discretionary Denial — The PTAB declined to institute the IPR.
• Judge panel: Not publicly available for discretionary denials without a full institution decision.
• Petition grounds: Not publicly detailed as the petition was discretionarily denied.
• Institution decision: Denied (Discretionary Denial) — 2026-03-11. The PTAB issued a decision denying institution under 35 U.S.C. § 314(a). The specific reasoning for the discretionary denial would be contained within the order, often relating to efficiency, parallel litigation, or other factors under Fintiv or NHK Spring precedents.
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: No Federal Circuit appeal has been initiated as the proceeding was denied institution and did not result in a final written decision on the merits.
• Defensive value: The discretionary denial means the validity of claims in US11671702 was not decided by the PTAB on the merits. While this means the claims technically "survived" the IPR, it doesn't strengthen their patentability against prior art, but rather indicates a procedural victory for the Patent Owner. However, the specific grounds raised in this petition by Samsung Electronics Co., Ltd. et al. are likely estopped from being raised again by them or their privies in future proceedings, under 35 U.S.C. § 315(e)(1).

Strategic summary

All claims of US11671702 remain UNTESTED by the PTAB on the merits. The single IPR filed, IPR2025-01520, was discretionarily denied, meaning the PTAB did not proceed to a full review of the patentability of the challenged claims. As such, no claims have been canceled or sustained through an AIA trial at the PTAB.

Regarding estoppel, the petitioner, Samsung Electronics Co., Ltd. et al., and any parties in privity with them, are estopped from raising in a future proceeding or civil action any ground that was raised or reasonably could have been raised in IPR2025-01520, according to 35 U.S.C. § 315(e)(1). For other potential defendants not in privity, the prior art grounds that could have been raised in IPR2025-01520 are theoretically still available for new IPR petitions.

There is no discernible pattern of multiple IPRs from the same petitioner or aggressive PTAB appeals by the patent owner at this time. The petitioner, Samsung Electronics Co., Ltd. et al., is a major operating company, indicating potential assertion of the patent against such entities.

Recommended next steps

For a defendant facing assertion of this patent, the full discretionary denial order for IPR2025-01520 should be reviewed to understand the PTAB's specific reasoning, which may reveal insights into potential future IPR strategies or weaknesses in the patent. The docket for IPR2025-01520 can be accessed via the Unified Patents portal (which cites the PTAB case). Given the discretionary denial, careful consideration should be given to whether a new IPR petition would face similar procedural hurdles, potentially by distinguishing the grounds or addressing the PTAB's stated concerns in the denial decision.

If the patent is currently being asserted, a deeper analysis of the claims and prior art could still reveal strong invalidity arguments that were not fully adjudicated at the PTAB due to the discretionary denial.
