PTAB challenges

Proceedings overview

One AIA trial proceeding has been filed against US patent 9843786, resulting in an institution denial. This leaves all claims of the patent untested by PTAB. For a defendant, this means the patent has not been subjected to IPR scrutiny, and all claims are presumed valid from a PTAB perspective.

IPR2025-01037 — Intel Corp. et al. v. General Video LLC

• Type: Inter Partes Review
• Filed: 2025-05-23
• Status: Discretionary Denial — the petition for IPR was denied institution by the PTAB.
• Judge panel: As of the current date, the specific judge panel for this discretionary denial is not publicly available in the provided information or easily retrievable through general search without access to the full PTAB filings for IPR2025-01037.
• Petition grounds: The detailed petition grounds (claims, art, statutory basis) are not publicly available in the provided information or easily retrievable through general search without access to the full PTAB filings for IPR2025-01037.
• Institution decision: Denied (date not specified in the provided information, but the "last modified" date of 2026-03-10 indicates activity post-filing that could relate to the decision). The reason for the denial was "Procedural", implying the denial was not based on the merits of patentability but on a procedural issue or discretion.
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied before trial.
• Appeal: No appeal to the Federal Circuit, as institution was denied.
• Defensive value: The petition for IPR2025-01037 was denied institution on procedural grounds, meaning the patent claims themselves were not evaluated for patentability in this proceeding. Therefore, this IPR has no direct impact on the validity of the patent's claims for a defendant. It indicates that the specific arguments and prior art presented in this petition were not advanced to a full trial.

Strategic summary

All claims of US9843786 remain untested by PTAB proceedings. IPR2025-01037 was denied institution on procedural grounds, meaning the merits of the patentability of the claims were not addressed. This implies that no claims have been canceled or sustained by the PTAB in this particular proceeding, and all claims are currently presumed valid.

The estoppel landscape for future petitioners remains largely open. Since IPR2025-01037 was denied institution, the petitioner (Intel Corp. et al.) and its privies are not estopped under 35 U.S.C. § 315(e)(2) from raising any grounds that were raised or reasonably could have been raised in this petition, as no final written decision was issued. This means that a defendant facing assertion of this patent still has a full range of prior-art grounds available for a potential future IPR.

Regarding pattern signals, only one IPR has been filed against US9843786, and it was denied institution. The petitioner, Intel Corp. et al., is a known entity that engages in patent challenges, suggesting a defensive aggregator like Unified Patents might be involved or that the patent has attracted attention from operating companies. The denial on "procedural" grounds suggests a potential technicality in the petition filing rather than a strong affirmation of the patent's validity on the merits.

Recommended next steps

If you are a defendant and are being asserted against with US9843786, the absence of a substantive PTAB review means the patent's claims have not been formally challenged and upheld or invalidated by the Board.

It would be advisable to:

• Investigate the specific reasons for the "Discretionary Denial" in IPR2025-01037, as this could reveal weaknesses in the original petition that might be avoided in a future challenge, or specific procedural hurdles implemented by the PTAB that are worth noting. This information would typically be found in the PTAB's Institution Decision, which can be accessed through the USPTO PTAB E2E system by searching for IPR2025-01037.
• Conduct a thorough prior art search to assess the patentability of the claims independently. Since no claims were tested, a strong prior art defense remains a viable strategy.
• Consider filing your own IPR petition if a robust prior art basis is found, as there are no estoppel issues stemming from IPR2025-01037. Ensure any new petition addresses the procedural issues that led to the prior denial.
• Monitor for any further PTAB activity on US9843786.
• The status "Not Instituted - Procedural" is listed on the Google Patents page as well.
