PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US patent 12240456, which is currently pending. This means the patent has not yet been subjected to a final validity determination by the PTAB, and its claims remain untested through this specific IPR process. The current defensive posture for a defendant is that the claims are presumed valid and the IPR is in its early stages.

IPR2026-00228 — Tesla, Inc. v. Bulletproof Property Management LLC

• Type: Inter Partes Review
• Filed: 2026-01-23
• Status: Pending. This IPR is in the preliminary stages, with the institution decision not yet issued. The statutory deadline for the institution decision is typically six months from the petition's filing date.
• Judge panel: The judge panel information is not yet publicly available through general web search for this pending proceeding.
• Petition grounds: Specific claims challenged, prior art cited, and statutory bases (§ 102 / § 103) are not yet publicly detailed through general web search. This information would typically be found in the filed petition, which is not readily accessible via public search results at this early stage.
• Institution decision: Not yet issued. The decision on whether to institute the IPR is expected around July 2026 (six months from the filing date).
• Final Written Decision: Not yet issued, as the IPR is still in the institution phase.
• Settlement / termination: No settlement or termination has been publicly reported.
• Appeal: No appeal activity, as no Final Written Decision has been issued.
• Defensive value: This proceeding indicates that at least one party, Tesla, Inc., is challenging the patentability of claims in US12240456. However, given its pending status, it offers no immediate defensive leverage beyond the existence of the challenge itself. The outcome of the institution decision and any subsequent Final Written Decision will be crucial for assessing the patent's strength.

Strategic summary

Currently, all claims of US12240456 remain UNTESTED by a Final Written Decision from the PTAB. IPR2026-00228 is in its initial phase, with no institution decision yet rendered, meaning no claims have been cancelled or sustained through this process.

Regarding the estoppel landscape, if IPR2026-00228 is instituted, Tesla, Inc. (and its privies) would be estopped under 35 U.S.C. § 315(e)(2) from asserting invalidity grounds that were raised or reasonably could have been raised during the IPR against the instituted claims. However, this estoppel only applies after a Final Written Decision. Until then, all prior-art grounds remain potentially available.

A pattern signal is that Tesla, Inc. is the petitioner in this IPR, which aligns with their position as a defendant in the related district court litigation (case 1:25-cv-00665). This suggests a coordinated defense strategy against Bulletproof Property Management LLC's patent assertions.

Recommended next steps

• Monitor IPR2026-00228: The next significant milestone for this IPR is the institution decision, which is anticipated around July 23, 2026. This decision will determine whether the PTAB will proceed with a full trial on the challenged claims. Monitoring the PTAB's Electronic Filing System for updates on this case is crucial.
• Review Petition Filings: If access to the PTAB E2E system is available, review the full petition for IPR2026-00228 to understand the specific claims challenged, the prior art cited, and the arguments presented by Tesla, Inc. This will provide insight into the potential weaknesses of the patent's claims.
