PTAB challenges

Proceedings overview

There have been two AIA trial proceedings filed against US Patent 11,069,337. Both IPRs were filed by Google LLC against Soundclear Technologies LLC. One IPR (IPR2025-01123) was terminated due to settlement, while the other (IPR2025-01597) was discretionarily denied institution. No claims of the patent have been invalidated or sustained by the PTAB in a Final Written Decision. This defensive posture indicates that the patent has not yet been subjected to substantive review of its claims' patentability at the PTAB, but has seen an attempted challenge successfully averted or settled.

IPR2025-01597 — Google LLC v. Soundclear Technologies LLC

• Type: Inter Partes Review
• Filed: 2025-09-29
• Status: Discretionary Denial – The PTAB declined to institute the review, meaning no trial was initiated.
• Judge panel: Not publicly available due to denial of institution.
• Petition grounds: Not publicly available as the petition was not instituted.
• Institution decision: Denied. The PTAB issued a Decision Denying Institution of Inter Partes Review on 2026-04-17. The precise reasoning for the discretionary denial is not immediately available from public snippets but typically involves factors such as parallel district court litigation, advanced stage of litigation, or efficient administration of justice.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable.
• Appeal: No appeal to the Federal Circuit, as no trial was instituted.
• Defensive value: This proceeding indicates that Google's attempt to challenge the patent through this IPR was unsuccessful at the institution phase. For a defendant, this means the patent has withstood one challenge without any claims being addressed on the merits, potentially making future IPR attempts by others (or Google on different grounds) more challenging due to the PTAB's discretionary factors.

IPR2025-01123 — Google LLC v. Soundclear Technologies LLC

• Type: Inter Partes Review
• Filed: 2025-06-12
• Status: Terminated-Settled – The parties reached a settlement agreement before a Final Written Decision was issued.
• Judge panel: Not publicly available without accessing the institution decision.
• Petition grounds: Not publicly available without accessing the institution decision.
• Institution decision: Information on whether institution was granted or denied is not immediately available from the provided snippets. However, the case was terminated due to settlement, which can occur either before or after institution.
• Final Written Decision: Not applicable, as the proceeding was terminated due to settlement.
• Settlement / termination: Terminated-Settled on 2025-10-31. The specific terms of the settlement are confidential.
• Appeal: Not applicable, as the proceeding was terminated due to settlement.
• Defensive value: This IPR was resolved by settlement. While it does not result in a PTAB decision on the merits of the patentability of the claims, it demonstrates that the parties involved found a mutually agreeable resolution. For a defendant facing assertion, this means the patent's claims remain untested by this specific IPR. The settlement may indicate a strategic decision by the petitioner rather than a concession on patentability.

Strategic summary

As of 2026-05-24, none of the claims of US Patent 11,069,337 have been canceled or found unpatentable by the PTAB. Both IPR challenges initiated by Google LLC have concluded without a substantive review of the claims' patentability. IPR2025-01597 was denied institution by the PTAB on discretionary grounds, and IPR2025-01123 was terminated due to a settlement between Google LLC and Soundclear Technologies LLC. Consequently, all claims of US11069337 remain untested and fully active from a PTAB perspective.

The estoppel landscape remains open for most potential petitioners. Since no Final Written Decision was issued in either IPR, the statutory estoppel provisions of 35 U.S.C. § 315(e)(2) do not formally apply to Google LLC (or its privies) for the grounds that were raised or reasonably could have been raised. However, any future IPR petitioner, especially Google LLC, would need to consider the PTAB's discretionary denial in IPR2025-01597 if attempting to challenge the patent on similar grounds or under similar circumstances. The presence of Google LLC as a petitioner in both IPRs suggests that the patent was of interest to a large technology company, a common pattern signal for patents being asserted or considered for assertion in the industry.

Recommended next steps

Since no claims of US11069337 have been invalidated or sustained by the PTAB, there is no Final Written Decision to link to for claim disposition. For IPR2025-01597, the Decision Denying Institution was issued on 2026-04-17. For IPR2025-01123, the proceeding was terminated by settlement on 2025-10-31. Defendants facing assertion of this patent should be aware that all claims remain intact from a PTAB perspective, and any future IPR challenge would be a first attempt at a substantive review on the merits. The discretionary denial in IPR2025-01597 highlights the importance of carefully considering discretionary factors when filing new IPR petitions against this patent. Defendants could research the specific reasoning for the discretionary denial to understand what factors led the PTAB to decline institution.
