PTAB challenges

Proceedings overview

One AIA trial proceeding has been filed against US patent 12214225, with a status of "Institution Denied." This outcome means the claims of the patent were not reviewed on the merits, which generally strengthens the patent owner's defensive posture as the claims remain intact.

PGR2026-00010 — Wella Operations US LLC v. Eric D. PRESSLY et al

• Type: Post-Grant Review
• Filed: 2025-11-04
• Status: Institution Denied – The PTAB declined to institute a review of the challenged claims.
• Judge panel: Not publicly available from the search results for the Institution Decision.
• Petition grounds: The petition challenged claims 1-20 of US Patent 12,214,225 B2 under 35 U.S.C. §§ 101, 102, and 103.
• Institution decision: Denied on 2026-04-23. The Board denied institution, determining that the petitioner, Wella Operations US LLC, did not demonstrate that claims 1-20 are unpatentable under 35 U.S.C. §§ 101, 102, or 103, and thus did not show a reasonable likelihood of prevailing with respect to at least one challenged claim.
• Final Written Decision: Not issued, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: There is no indication of an appeal to the Federal Circuit regarding the denial of institution for PGR2026-00010 in the search results.
• Defensive value: The patent owner prevailed at the institution stage, meaning the claims were not invalidated or even formally challenged on the merits by this proceeding. For a defendant, this indicates that an attempt to invalidate claims 1-20 via PGR on the grounds raised by Wella Operations US LLC was unsuccessful, and the patent's claims remain robust against these specific arguments. A new PGR petition would need to present substantially different and compelling arguments to have a chance at institution.

Strategic summary

All 20 claims of US patent 12214225 remain untested by an AIA trial proceeding. The sole Post-Grant Review, PGR2026-00010, filed by Wella Operations US LLC, was denied institution, meaning the PTAB did not find sufficient merit in the petition's arguments to proceed to a full review. As a result, no claims have been canceled or narrowed, and all claims (1-20) are currently sustained.

Regarding the estoppel landscape, since institution was denied in PGR2026-00010, statutory estoppel under 35 U.S.C. § 315(e)(2) does not apply to Wella Operations US LLC or its privies for the grounds raised. However, depending on the specific reasons for the denial, principles of res judicata or collateral estoppel might make it difficult for Wella to re-challenge the same claims on the exact same grounds. For other potential defendants, this institution denial poses no estoppel, meaning they are free to challenge the patent on any available prior-art grounds. The initial Google Patents listing mentions "Unified Patents PTAB Data" as a petitioner, but the specific "PTAB proceedings on file" block in the prompt explicitly states "Wella Operations US LLC." I have used Wella Operations US LLC as the petitioner based on the provided canonical list.

The current pattern signals show a patent that has successfully defended against an initial PTAB challenge. The lack of instituted proceedings or subsequent filings could indicate a perceived strength of the patent's claims or that potential challengers are assessing the denial reasoning before acting.

Recommended next steps

For a defendant facing assertion of this patent, the PTAB's denial of institution in PGR2026-00010 is an important data point. It indicates that the arguments presented by Wella against claims 1-20 under §§ 101, 102, and 103 were not persuasive enough to meet the institution threshold.
A defendant should obtain and thoroughly analyze the "Institution Denied" decision for PGR2026-00010 (available at USPTO PTAB Decisions) to understand the PTAB's specific reasoning for denying institution. This analysis will be crucial to determine if a new PTAB petition can be crafted with different or stronger arguments and evidence to overcome the previous denial.
Given that there are no active PTAB proceedings, the patent currently stands with all its claims intact. The absence of further PTAB activity after the denial suggests that potential challengers might be hesitant or still strategizing.
