PTAB challenges

Proceedings overview

As of May 29, 2026, there is one active Post-Grant Review (PGR) proceeding, PGR2026-00045, on file for US Patent 12,395,359. This proceeding is currently in the preliminary phase, with no institution decision yet rendered. Therefore, no claims have been invalidated or sustained by the PTAB at this time. This gives a defendant facing assertion of this patent an opportunity to monitor the ongoing challenge and potentially leverage its outcome, but the patent's claims remain presumptively valid.

PGR2026-00045 — Okta, Inc. et al. v. Thales DIS France SA

• Type: Post-Grant Review (PGR)
• Filed: 2026-05-07
• Status: Pending. The proceeding is in the preliminary stage, awaiting a decision on institution.
• Judge panel: Information regarding the assigned judge panel is not publicly available in immediate search results for this recently filed case.
• Petition grounds: The detailed petition grounds, including which specific claims are challenged, the prior art asserted, and the statutory bases (§ 102 / § 103 / § 112), are typically contained within the petition document itself. As of today's date, this information is not readily summarized in public search results for this newly filed PGR.
• Institution decision: Not yet issued. The PTAB has a statutory deadline of six months from the petition's filing date (approximately November 7, 2026) to decide whether to institute the PGR.
• Final Written Decision: Not applicable. No Final Written Decision has been issued as the case is in its early stages.
• Settlement / termination: Not applicable. The case is still active and has not been settled or terminated.
• Appeal: Not applicable. There has been no Final Written Decision to appeal.
• Defensive value: This active PGR indicates that the patent's claims are currently under examination by the PTAB. If Okta, Inc. et al. are successful in instituting the PGR, and subsequently in invalidating claims, it could significantly weaken the patent owner's position. Conversely, if institution is denied or claims are sustained, it would strengthen the patent. Defendants should closely monitor this proceeding for its potential impact.

Strategic summary

Currently, all claims (1-14) of US 12,395,359 are UNTESTED by a final PTAB decision, as the single pending PGR, PGR2026-00045, is in its very early stages. No claims have been canceled or sustained by the PTAB. The patent has not been narrowed through any AIA trial, and its full scope remains intact.

Regarding the estoppel landscape, since PGR2026-00045 has not yet reached an institution decision, no estoppel under § 315(e)(2) or § 325(e)(2) has attached to the petitioner (Okta, Inc. et al.) or its privies. All prior-art grounds, including those that may be raised in the pending PGR, are still theoretically available to other potential challengers or defendants. There are no clear pattern signals from this single, recent filing, such as multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner. The patent owner, Thales, is a large operating company, which is common for patent prosecution but doesn't inherently signal NPE behavior in PTAB filings.

Recommended next steps

Since PGR2026-00045 is pending, any defendant facing assertion of US 12,395,359 should:

• Monitor the PTAB docket for PGR2026-00045 (USPTO E2E link: https://ptab.uspto.gov/#/proceeding/PGR2026-00045) closely, particularly for the institution decision, which is expected around November 7, 2026.
• Review the petition once it becomes fully public to understand the specific claims challenged and the prior art asserted by Okta, Inc. et al. This information will be crucial for assessing the strength of the challenge.
• Evaluate whether the grounds raised in PGR2026-00045 are relevant to any infringement theories being asserted.
