PTAB challenges

Proceedings overview

One Post-Grant Review (PGR) proceeding, PGR2026-00026, has been filed against US patent 12305206 by Albaugh, LLC, and is currently in the early, pre-institution phase. This means no claims have been invalidated or sustained by the PTAB yet. For a defendant, this indicates that the patent is currently undergoing a validity challenge at the USPTO, and the outcome of this proceeding will be crucial for any future assertion of the patent.

PGR2026-00026 — Albaugh, LLC v. BASF SE

• Type: Post-Grant Review
• Filed: 2026-02-20
• Status: Pending. The petition was filed, and the proceeding is in the pre-institution phase.
• Judge panel: The judge panel information is not publicly available at this early stage of the proceeding.
• Petition grounds: The specific claims challenged and prior art asserted in the petition for PGR2026-00026 are not available from the provided search snippets. A PGR allows for broader grounds for challenging patent validity than an IPR, including challenges under §§ 101, 102, 103, and 112 (except for best mode).
• Institution decision: Not yet issued. The Patent Owner has two months from the filing date (February 20, 2026) to file a brief requesting discretionary denial, and the Petitioner has three months from the notice date to oppose this request. The Patent Owner may also file a preliminary response within three months of the notice date.
• Final Written Decision: Not applicable; no decision has been issued yet.
• 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: This active PGR indicates that the patent's validity is currently under scrutiny at the PTAB. If the PGR is instituted and proceeds to a Final Written Decision, the outcome could significantly impact the strength of the patent. While pending, it introduces uncertainty regarding the patent's enforceability.

Strategic summary

Currently, all claims of US patent 12305206 are UNTESTED by a Final Written Decision from the PTAB. The single Post-Grant Review, PGR2026-00026, is in its initial stages, meaning no claims have been canceled or sustained by the Board. The patent owner, BASF SE, is currently defending the patent's validity against the petitioner, Albaugh, LLC.

Regarding the estoppel landscape, since no institution decision has been made, there is no estoppel under 35 U.S.C. § 315(e)(2) for the petitioner (Albaugh, LLC) or its privies yet. If the petition is instituted, estoppel would only apply to grounds that were raised or reasonably could have been raised by the petitioner in the proceeding, upon a final written decision. PGRs are generally "favored" in the PTAB's discretionary denial calculus due to their tight filing window (no later than nine months from patent grant) and proximity to examination, which might make it harder for the patent owner to achieve discretionary denial compared to an IPR.

There are no apparent pattern signals, such as multiple proceedings by the same petitioner or aggressive PTAB appeals by the patent owner, given that only one proceeding has been filed and it is still very early.

Recommended next steps

For a defendant facing assertion of US patent 12305206:

• Monitor PGR2026-00026 closely: The institution decision for PGR2026-00026 is a critical upcoming milestone. It is typically issued within six months of the petition filing date (February 20, 2026), meaning an institution decision is expected around August 2026. The Patent Owner has two months from the notice date to file a brief requesting discretionary denial, and the Petitioner has three months from the notice date to oppose this request. The Patent Owner may also file a preliminary response to the petition no later than three months from the date of the notice.
• Review the filed petition: Although not explicitly provided in the search results, obtaining and thoroughly analyzing the petition filed in PGR2026-00026 is crucial. This document will detail the specific claims challenged and the prior art and statutory grounds (§§ 101, 102, 103, and/or 112) used to challenge them. This information is essential for understanding the potential weaknesses of the patent and for informing any parallel defense strategy.
• Assess potential for intervention/joinder: If considering a PTAB challenge, evaluate the claims and grounds in PGR2026-00026. If the claims or art are relevant to your interests, consider potential joinder opportunities if institution is granted.
• No PTAB activity beyond this PGR: There is currently no other PTAB activity (e.g., IPRs or CBMs) on file for US patent 12305206, other than the pending PGR2026-00026.
