PTAB challenges

Proceedings overview

Two Inter Partes Review (IPR) proceedings, IPR2025-01035 and IPR2025-01034, have been filed against US Patent 12037004. Both petitions have a status of "Discretionary Denial," meaning the PTAB declined to institute a full review of the challenged claims. This indicates that the patent has survived these initial challenges and is hardened against these specific IPRs, providing a strong defensive posture for the patent owner against these petitioners and grounds.

IPR2025-01035 — Tesla Inc. v. Granite Vehicle Ventures LLC

• Type: Inter Partes Review
• Filed: 2025-05-28
• Status: Discretionary Denial. This means the PTAB, in its discretion, declined to institute an IPR trial. It does not reflect a ruling on the merits of the patentability challenges.
• Judge panel: Not publicly available in the provided information. However, institution decisions are typically made by the Director of the USPTO in consultation with at least three PTAB judges.
• Petition grounds: The specific claims, prior art, and statutory bases (§ 102 / § 103 / § 112) for the petition are not detailed in the provided information.
• Institution decision: Denied (Discretionary Denial) on 2025-12-04. The reasoning for discretionary denial often involves factors beyond the merits of the patentability challenge, such as the stage of parallel district court litigation or inconsistent claim construction positions by the petitioner.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: Not applicable, as institution was denied. Appeals to the Federal Circuit are generally barred for institution decisions.
• Defensive value: The patent owner prevailed at the institution stage, meaning the claims challenged in this IPR were not subjected to a full PTAB review based on the arguments presented by Tesla Inc. This makes an IPR-based defense using the same or similar grounds against this patent by Tesla Inc. or its privies significantly harder due to estoppel.

IPR2025-01034 — Tesla Inc. et al. v. Granite Vehicle Ventures LLC

• Type: Inter Partes Review
• Filed: 2025-05-28
• Status: Discretionary Denial. This means the PTAB, in its discretion, declined to institute an IPR trial. It does not reflect a ruling on the merits of the patentability challenges.
• Judge panel: Not publicly available in the provided information. However, institution decisions are typically made by the Director of the USPTO in consultation with at least three PTAB judges.
• Petition grounds: The specific claims, prior art, and statutory bases (§ 102 / § 103 / § 112) for the petition are not detailed in the provided information.
• Institution decision: Denied (Discretionary Denial) on 2025-12-04. The reasoning for discretionary denial often involves factors beyond the merits of the patentability challenge, such as the stage of parallel district court litigation or inconsistent claim construction positions by the petitioner.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: Not applicable, as institution was denied. Appeals to the Federal Circuit are generally barred for institution decisions.
• Defensive value: The patent owner prevailed at the institution stage, meaning the claims challenged in this IPR were not subjected to a full PTAB review based on the arguments presented. This makes an IPR-based defense using the same or similar grounds against this patent by the petitioner (Tesla Inc. et al.) or their privies significantly harder due to estoppel.

Strategic summary

Currently, all claims of US Patent 12037004 remain UNTESTED on the merits through PTAB proceedings, as both IPR2025-01035 and IPR2025-01034 resulted in discretionary denials of institution. This means no claims have been canceled or sustained by the PTAB in these proceedings. The patent owner, Granite Vehicle Ventures LLC, has successfully fended off these challenges at the initial stage.

The estoppel landscape under § 315(e)(2) will bar Tesla Inc. (and any parties in privity with them) from asserting, in any other civil action or ITC proceeding, invalidity grounds that were raised or reasonably could have been raised in IPR2025-01035 and IPR2025-01034. Since both petitions were denied institution, the specific prior-art grounds that "reasonably could have been raised" might be a point of contention, but the petitioner is generally estopped from re-litigating grounds that were presented to the PTAB. For a defendant currently being asserted against who is not Tesla Inc. or in privity with them, all prior-art grounds remain available.

Both IPRs were filed by Tesla Inc. (or Tesla Inc. et al.), indicating a concerted effort by this entity to challenge the patent. The fact that both were met with discretionary denials suggests a potential pattern related to the PTAB's discretionary denial factors, which can include the status of parallel litigation or positions taken by the petitioner in other forums.

Recommended next steps

Since both IPRs resulted in discretionary denials, there are no claims invalidated to cite in a defense. No active proceedings are pending at the trial stage for US Patent 12037004.
