IPR2026-00379 — Tesla Inc. v. CHARGELOGIC LLC

• Type: Inter Partes Review
• Filed: 2026-06-18
• Status: Pending. This IPR was filed recently and has not yet reached the institution decision stage.
• Judge panel: Information regarding the assigned judge panel is not yet publicly available through general web search for such a newly filed proceeding.
• Petition grounds: Specific details regarding the claims challenged, prior art cited, and statutory bases (§ 102 / § 103 / § 112) of the petition are not yet publicly available through general web search for this recently filed IPR.
• Institution decision: Not yet decided. The PTAB has a statutory deadline of six months from the filing date of the preliminary response (or waiver thereof) to issue an institution decision. Given the IPR was filed on 2026-06-18, the institution decision is pending.
• Final Written Decision: Not applicable; the proceeding has not reached this stage.
• Settlement / termination: Not applicable; the proceeding is active and in its early stages.
• Appeal: Not applicable; no Final Written Decision has been issued.
• Defensive value: As this IPR is in its very early stages, it currently offers no definitive defensive value regarding claim validity. However, the fact that Tesla Inc. has filed an IPR indicates a potential challenge to the patent's validity, which could impact future assertion strategies if claims are ultimately invalidated. For a defendant facing assertion, monitoring this IPR's progress will be crucial.

Strategic summary

Currently, all claims of US11508996 are UNTESTED through the PTAB AIA trial process, as the single filed IPR (IPR2026-00379) is still pending and has not yet reached an institution decision. This means no claims have been canceled or sustained by the PTAB.

The estoppel landscape under § 315(e)(2) has not yet been formed, as no Final Written Decision has been issued. Once an FWD is issued, the petitioner (Tesla Inc.) and its privies will be barred from asserting in district court or the ITC any grounds of invalidity that were raised or reasonably could have been raised in the IPR. For other defendants, all prior-art grounds remain available for challenge unless they are in privity with Tesla.

The filing of IPR2026-00379 by Tesla Inc. is a significant signal, as Tesla is a major player in the electric vehicle industry. This suggests that the patent's claims are relevant to their interests and that they perceive potential validity weaknesses. The patent owner, CHARGELOGIC LLC, will now need to defend the patent's claims before the PTAB.

Recommended next steps

For a defendant currently being asserted against, the primary next step would be to closely monitor IPR2026-00379. Key upcoming milestones include the filing of the Patent Owner's Preliminary Response and the subsequent institution decision by the PTAB. The institution decision, which is due approximately six months after the filing of the preliminary response (or its waiver), will indicate which, if any, claims and grounds will proceed to trial. The statutory deadline for the Final Written Decision, if the IPR is instituted, will be one year from the date of institution. Access to the full petition document, ideally through the USPTO PTAB E2E system, would provide detailed information on the specific claims challenged and prior art asserted by Tesla, which could inform a defendant's own invalidity analyses.

It is worth noting that the patent has Google Patents listing "Family has litigation," with a US case filed in the Texas Western District Court, indicating ongoing district court activity which may be related to the IPR.
