PTAB challenges

Proceedings overview

There is one active Post-Grant Review (PGR) proceeding currently on file for US Patent 12353917, which is in a pending status. This means no claims have been invalidated or sustained by the Patent Trial and Appeal Board (PTAB) yet. For a defendant, this indicates that the patent's claims are currently under challenge, but their validity has not yet been finally determined by the PTAB.

PGR2026-00042 — Wealth Inc. v. Vanilla Technologies Inc.

• Type: Post-Grant Review
• Filed: 2026-04-07
• Status: Pending. The petition has been filed and is awaiting a decision on institution by the PTAB.
• Judge panel: Information not publicly available yet at this early stage of the proceeding.
• Petition grounds: Wealth Inc. has challenged all 20 claims of the '917 patent. The petition alleges that the claims are invalid on two primary grounds: ineligibility under 35 U.S.C. § 101, and obviousness based on prior art.
• Institution decision: Not yet issued. The PTAB typically has six months from the petition filing date to decide whether to institute a Post-Grant Review.
• Final Written Decision: Not applicable as institution has not yet occurred.
• Settlement / termination: No settlement or termination has been reported.
• Appeal: No appeal has been filed as no Final Written Decision has been issued.
• Defensive value: This proceeding indicates that all 20 claims of US Patent 12353917 are currently under review for validity. Any assertion of these claims should consider the potential for their cancellation, particularly if the institution decision is favorable to the petitioner.

Strategic summary

As of 2026-05-29, all 20 claims of US Patent 12353917 are currently UNTESTED by a Final Written Decision, as the single Post-Grant Review (PGR2026-00042) is in a pending status awaiting an institution decision. No claims have been canceled or sustained by the PTAB.

The estoppel landscape under 35 U.S.C. § 315(e)(2) for Wealth Inc. (and its privies) will only become active if the PGR is instituted and proceeds to a Final Written Decision. If the PTAB issues a Final Written Decision, Wealth Inc. would be estopped from raising any ground that it raised or reasonably could have raised during the PGR. For any other defendant, all prior-art grounds, including those for ineligibility under § 101 and obviousness under § 103, remain available for challenge in future proceedings or litigation, as there is no final PTAB determination on any claim yet.

There are no pattern signals to discern at this time, as only one PGR has been filed on this patent, and it is in its nascent stages. There is no indication of multiple filings by the same petitioner, aggressive PTAB appeals by the patent owner, or involvement of defensive aggregators.

Recommended next steps

As PGR2026-00042 is still pending, the critical upcoming milestone is the institution decision deadline. The PTAB has a statutory deadline of six months from the petition filing date (2026-04-07) to decide whether to institute the PGR. This means an institution decision can be expected by approximately 2026-10-07. A defendant facing assertion of this patent should closely monitor the PTAB's institution decision for PGR2026-00042, as it will significantly impact the perceived strength and validity of the patent. Access to the public docket for PGR2026-00042 on the USPTO PTAB E2E system would provide real-time updates on filings and orders.
