PTAB challenges

Proceedings overview

There are two AIA trial proceedings on file for US Patent 11262766. One proceeding has a status of Discretionary Denial, meaning institution was denied, and the other has a status of Trial Instituted, indicating that a trial is ongoing for that IPR. This gives a defendant a mixed defensive posture; one challenge was dismissed at the institution phase, while another is actively challenging the patent's validity.

IPR2026-00159 — Wybotics, Co. Ltd. et al. v. Zodiac Pool Systems LLC

• Type: Inter Partes Review
• Filed: 2025-11-25
• Status: Trial Instituted – The PTAB has granted the petition and initiated a trial to assess the patentability of the challenged claims.
• Judge panel: Not publicly available in the provided information.
• Petition grounds: Not publicly available in the provided information.
• Institution decision: Instituted – A notice from the USPTO indicates that institution was granted for IPR2026-00159. The specific reasoning for institution is not detailed in the available snippets.
• Final Written Decision (if issued): Not yet issued, as the status is "Trial Instituted."
• Settlement / termination: Not settled or terminated.
• Appeal: No appeal information available, as a Final Written Decision has not been issued.
• Defensive value: This active IPR proceeding indicates that the patentability of claims in US11262766 is currently being challenged. A defendant facing assertion of this patent should closely monitor the outcome of this IPR, as a final written decision finding claims unpatentable would significantly weaken the patent owner's position.

IPR2026-00200 — Beatbot Technology (USA) Co. Ltd. et al. v. Zodiac Pool Systems LLC

• Type: Inter Partes Review
• Filed: 2026-01-26
• Status: Discretionary Denial – The PTAB denied institution of the IPR, likely based on discretionary factors.
• Judge panel: Not publicly available in the provided information. (Note: Since October 20, 2025, the USPTO Director decides whether to institute IPR and PGR trials, rather than a panel of APJs.)
• Petition grounds: Not publicly available in the provided information.
• Institution decision: Denied – The institution of inter partes review was denied for IPR2026-00200. The specific reasoning for the discretionary denial is not detailed in the available snippets, but discretionary denials can occur for various reasons, including considerations related to parallel litigation or the efficient administration of the PTAB.
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: While petitions challenging IPR institution denials have been filed at the Federal Circuit, they have generally been rejected. It is not known if an appeal was filed for this specific case.
• Defensive value: The discretionary denial of this IPR means that the challenged claims of US11262766 were not subjected to a full PTAB trial in this specific proceeding. This strengthens the patent owner's position against challenges based on the grounds presented in this particular petition. However, it does not prevent new IPR petitions from being filed on different grounds or by different parties, subject to statutory bars and discretionary considerations.

Strategic summary

Currently, the patent US11262766 is facing an active challenge in IPR2026-00159, where a trial has been instituted, meaning the patentability of certain claims is under review by the PTAB. The specific claims under challenge are not detailed in the provided information. Conversely, IPR2026-00200, filed by Beatbot Technology, was met with a discretionary denial, indicating that the PTAB, under the Director's new institution policy (effective October 20, 2025), chose not to proceed with a full review. Therefore, for the grounds raised in IPR2026-00200, the claims remain untested by a PTAB final written decision. The current status suggests that some claims of US11262766 are under active review in IPR2026-00159 and thus are neither definitively sustained nor canceled, while other claims (potentially those challenged in the denied IPR) remain unchallenged at the PTAB.

Regarding the estoppel landscape, for IPR2026-00200, because institution was denied, the petitioner (Beatbot Technology) is generally not estopped under § 315(e)(2) from raising those same grounds in district court or the ITC, as no final written decision on the merits was issued. However, for IPR2026-00159, if a final written decision is issued, the petitioner (Wybotics) and its privies would be estopped from asserting invalidity grounds that were raised or reasonably could have been raised during the IPR. Unified Patents, a defensive aggregator, has filed IPRs in other cases, but is not listed as a petitioner for IPR2026-00159 or IPR2026-00200 against this patent.

Recommended next steps

For a defendant currently facing assertion of US patent 11262766, the most critical next step is to closely monitor IPR2026-00159, which is in the "Trial Instituted" phase. The outcome of this proceeding will directly impact the validity of the challenged claims. You should aim to determine which specific claims are being challenged in IPR2026-00159 and the asserted prior art. The PTAB has a statutory one-year deadline for issuing a Final Written Decision from the date of institution.

Additionally, while IPR2026-00200 was denied institution, understanding the reasoning behind the discretionary denial would be valuable. Although the decision itself is not publicly detailed in the provided snippets, discretionary denials can sometimes be influenced by factors such as parallel district court litigation or the strength of the petition compared to a patent owner's preliminary response.
