IPR2025-00472 — Google LLC v. BrodTi Inc.

• Type: Inter Partes Review
• Filed: 2025-01-17
• Status: Final Written Decision
• Judge panel: Not publicly available from the provided patent information or general Google Patents litigation links. I would need access to the PTAB E2E system to confirm the specific judge panel.
• Petition grounds: The specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103) are not available from the provided patent text. This information would typically be found in the institution decision and the petition itself.
• Institution decision: The proceeding status indicates "Instituted" (as it has reached a Final Written Decision). The specific date of institution and the Board's reasoning for instituting on particular claims and grounds are not provided in the patent text and would require accessing the institution decision document from the PTAB E2E system. The provided information only states "Pending - Instituted" for the IPR.
• Final Written Decision (if issued): As of July 1, 2026, the status is "Final Written Decision". However, the specific verdict at a claim-level granularity (which claims were canceled, sustained, or held patentable) and the panel's reasoning are not available in the provided patent text. This information would be contained within the public FWD document on the USPTO PTAB Decisions portal.
• Settlement / termination: No information regarding settlement or termination is provided in the patent text.
• Appeal: No information regarding an appeal to the Federal Circuit is provided in the patent text.
• Defensive value: Without the details of the Final Written Decision, the defensive value is unknown. If claims were invalidated, it would significantly narrow the scope of the patent for any defendant. If claims were upheld, it would indicate a hardened patent against these specific IPR grounds.

Strategic summary

As of July 1, 2026, there is one concluded AIA trial proceeding (IPR2025-00472) for US Patent 11416898, which has reached a Final Written Decision. The current status "Final Written Decision" means the Board has issued a ruling on the patentability of the challenged claims. However, without access to the full FWD document, it is not possible to determine which claims of 11416898 are CANCELED vs. SUSTAINED vs. UNTESTED. This significantly impacts the assessment of the patent's strength and the viability of any infringement theories.

The estoppel landscape, per § 315(e)(2), would bar Google LLC (the petitioner) and its privies from raising any ground they raised or reasonably could have raised in this IPR. For other defendants facing assertion, the prior-art grounds remain available, subject to any specific findings in the FWD regarding the patentability of the claims and the prior art considered. No pattern signals can be observed from a single proceeding.

Recommended next steps

To understand the full impact of IPR2025-00472, a defendant should:

1. Obtain and review the Final Written Decision for IPR2025-00472. This document will explicitly state which claims, if any, were found unpatentable and which were confirmed. The FWD would be accessible via the USPTO PTAB Decisions database by searching for "IPR2025-00472". This will be critical for understanding the current scope and enforceability of US11416898.
2. Analyze the grounds for invalidation (or confirmation). The FWD will detail the specific prior art and statutory bases (§ 102/103) used by the Board. This analysis is crucial for understanding the estoppel implications for the petitioner and informing potential defenses for other parties.
3. Check for Federal Circuit appeal. While no appeal information is explicitly provided, it is common for FWDs to be appealed. The Federal Circuit's docket should be checked using the IPR number or patent owner/petitioner names to see if an appeal was filed and its current status.

IPR2025-00472 — Google LLC v. BrodTi Inc.

• Type: Inter Partes Review
• Filed: 2025-01-17
• Status: Final Written Decision
• Judge panel: The specific judge panel for IPR2025-00472 is not explicitly provided in the public information available. However, Frances L. Ippolito is listed as a panel judge in an IPR with the same number, but the status is "Pending - Instituted" for Google LLC v. Brodti Inc.. Other common PTAB judges mentioned in general 2025 PTAB activity include Ken B. Barrett, James A. Tartal, Robert J. Silverman, and Jeffrey N. Fredman.
• Petition grounds: The specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103) are not available from the provided patent text or general search results. This information would typically be detailed in the petition and institution decision document. IPR challenges are statutorily constrained to invalidity challenges under Sections 102 and 103, based on prior art consisting of patents and printed publications.
• Institution decision: The proceeding status indicates "Instituted" (as it has reached a Final Written Decision). The institution decision for IPR2025-00472 was dated 2025-07-24. The Board institutes an IPR if it determines there is a reasonable likelihood that the petitioner would prevail with respect to at least one challenged claim. Historically, the Board's institution rate has varied, and the Director can exercise discretion to deny institution based on various factors, including co-pending litigation (Fintiv factors), settled expectations (e.g., patent age, commercialization, assertion history), and the petitioner's litigation strategy.
• Final Written Decision (if issued): The proceeding status is "Final Written Decision," meaning the Board has issued a ruling on the patentability of the challenged claims. However, the specific verdict at a claim-level granularity (which claims were canceled, sustained, or held patentable) and the panel's reasoning are not available in the provided patent text or general search results. This information would be contained within the public FWD document on the USPTO PTAB Decisions portal.
• Settlement / termination: No information regarding settlement or termination is provided in the patent text or search results.
• Appeal: No information regarding an appeal to the Federal Circuit is provided in the patent text or search results. Challenges to institution decisions are generally unreviewable on appeal. However, merits-based determinations in a FWD can be appealed to the Federal Circuit.
• Defensive value: The defensive value of IPR2025-00472 is currently unknown without the specifics of the Final Written Decision. If claims were invalidated, it could significantly limit the scope of the patent for any defendant. If claims were upheld, it would suggest a patent that has withstood a validity challenge, potentially strengthening the patent owner's position.

Strategic summary

As of July 1, 2026, IPR2025-00472 has concluded with a Final Written Decision. However, the critical outcome—which claims of US11416898 were CANCELED versus SUSTAINED versus UNTESTED—is not available without reviewing the actual Final Written Decision document. This lack of information leaves a significant gap in understanding the current enforceability and scope of the patent.

Regarding the estoppel landscape, Google LLC (the petitioner in IPR2025-00472) and its privies would be estopped from raising any ground that was raised or reasonably could have been raised in the IPR with respect to any claim that reached a Final Written Decision. For other potential defendants, prior art grounds remain available, provided they were not actually litigated and decided in this IPR or fall outside the scope of IPR (e.g., § 112 grounds or certain public use/on sale grounds). There are no discernible pattern signals, such as multiple IPRs from the same petitioner or aggressive PTAB appeals by the patent owner, given only one proceeding is on record.

Recommended next steps

1. Obtain and review the Final Written Decision for IPR2025-00472 immediately. This document is paramount. It will provide the definitive legal status of the challenged claims of US11416898. The FWD would be publicly accessible through the USPTO PTAB Decisions portal. Without this document, any assessment of the patent's validity and defensive strategy is speculative. The FWD will detail the specific claims addressed and the Board's findings (e.g., "Claims 1-5 are found unpatentable," or "Claims 1-5 are found patentable").
2. Analyze the FWD for claim-by-claim outcomes and reasoning. Pay close attention to the Board's interpretation of the claims and the prior art. If claims were invalidated, specifically note the invalidated claim numbers and the prior art references cited. This information will inform any non-infringement or invalidity arguments.
3. Investigate any Federal Circuit appeal. Determine if the Final Written Decision for IPR2025-00472 has been appealed to the Federal Circuit. This can be checked on CourtListener or the Federal Circuit's official docket by searching for the IPR number or the parties involved. An ongoing appeal could alter the final status of the claims.
