PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 11909010. It is an Inter Partes Review (IPR) currently in a pending status. This means the patent's validity is currently under challenge, and no claims have been definitively invalidated or sustained by the PTAB through a final written decision. For a defendant, this indicates the patent is actively being tested, and its long-term defensive posture depends on the outcome of this pending IPR.

IPR2026-00381 — Tesla Inc. v. CHARGELOGIC LLC

• Type: Inter Partes Review
• Filed: 2026-06-18
• Status: Pending – The petition has been filed, and the Patent Trial and Appeal Board (PTAB) has not yet issued a decision on whether to institute the review.
• Judge panel: Information regarding the assigned judge panel is not yet publicly available, as the proceeding is in its early stages before an institution decision.
• Petition grounds: Details of the specific claims challenged, prior art references, and statutory bases (§ 102 for anticipation, § 103 for obviousness, or § 112 for written description/enablement issues) raised in the petition are not yet publicly available since the institution decision has not been made.
• Institution decision: The PTAB has not yet issued a decision on institution. Under statute, the Board typically has six months from the petition's filing date to decide whether to institute review. Therefore, a decision is anticipated around 2026-12-18.
• Final Written Decision: Not applicable, as the IPR has not yet reached the institution phase, let alone a final written decision.
• Settlement / termination: Not applicable, as the proceeding is in its initial pending phase.
• Appeal: Not applicable, as no final written decision has been issued by the PTAB.
• Defensive value: This IPR means that the patent US11909010 is currently under direct challenge for its patentability. While the claims remain "untested" by a final PTAB decision, a defendant facing assertion of this patent should closely monitor this proceeding, as its outcome will directly impact the patent's strength and the viability of invalidity arguments.

Strategic summary

Currently, all claims of US Patent 11909010 are considered UNTESTED by any PTAB final written decision. The patent is the subject of a newly filed Inter Partes Review, IPR2026-00381, by Tesla Inc. against CHARGELOGIC LLC. Since this IPR was filed on 2026-06-18, it is in its earliest stages, and no substantive decisions regarding claim validity have been rendered. This means the patent has not yet been narrowed through PTAB proceedings, nor have its claims been judicially affirmed by a final written decision.

Regarding the estoppel landscape, no estoppel currently applies under 35 U.S.C. § 315(e)(2) for this patent. This is because estoppel only arises after a final written decision is issued in an IPR. Until such a decision is made, a defendant currently being asserted against would not be barred from raising any prior-art grounds that could have been raised in an IPR, provided they are not otherwise estopped by other means (e.g., prior district court litigation).

This is the first IPR filed against US Patent 11909010, indicating an initial challenge to the patent. The involvement of Tesla Inc. as a petitioner suggests potential commercial interest in the technology covered by the patent or in the ongoing litigation. No pattern of multiple IPR filings by the same petitioner or aggressive PTAB appeals by the patent owner can be observed at this early stage.

Recommended next steps

For a defendant facing an assertion of US11909010, the immediate recommended step is to closely monitor IPR2026-00381. The most critical upcoming milestone is the institution decision, expected around 2026-12-18. If the IPR is instituted, the PTAB will then proceed to trial, which typically has a statutory deadline of one year from institution to reach a Final Written Decision. The outcome of this institution decision will significantly influence the defensive strategy regarding this patent.
