IPR2026-00245 — FanDuel, Inc. et al. v. Winview IP Holdings LLC

• Type: Inter Partes Review
• Filed: 2026-02-03
• Status: Pending. The petition has been filed, and the PTAB is currently evaluating whether to institute the trial. The last modification date of 2026-05-12 indicates ongoing activity, likely related to preliminary responses or PTAB internal review.
• Judge panel: Information regarding the assigned judge panel is not publicly available at this stage of the proceeding from the provided search results.
• Petition grounds: The specific claims challenged, prior art references, and statutory bases (§ 102 / § 103) are not detailed in the provided information or readily available from general public records without direct access to the petition.
• Institution decision: Not yet issued. The statutory deadline for the institution decision is typically six months from the filing date, which would be around 2026-08-03.
• Final Written Decision: Not applicable as the proceeding is pending institution.
• Settlement / termination: No information regarding settlement or termination is available as the proceeding is pending.
• Appeal: Not applicable as no Final Written Decision has been issued.
• Defensive value: As this IPR is still pending institution, it currently has no direct impact on the patent's validity. However, the existence of a petition from a known entity like FanDuel, Inc. suggests that the patent's claims are being scrutinized. If instituted, it will indicate the PTAB believes there is a reasonable likelihood that at least one claim is unpatentable, requiring the patent owner to defend those claims.

Strategic summary

Currently, all claims of US patent 12005349 remain untested by a PTAB Final Written Decision. The single Inter Partes Review, IPR2026-00245, is in the pre-institution phase, meaning no claims have been canceled or confirmed patentable by the PTAB yet. Without details on the specific claims challenged in the petition for IPR2026-00245, it is not possible to identify which claims are currently under threat or which remain entirely untested by this specific proceeding.

Regarding the estoppel landscape, if IPR2026-00245 is instituted and proceeds to a Final Written Decision, § 315(e)(2) would bar the petitioner (FanDuel, Inc. et al.) and their privies from raising any ground they raised or reasonably could have raised during the IPR. However, since the proceeding is pending institution, the scope of potential estoppel is not yet defined. For a defendant being asserted against who is not a privy to FanDuel, Inc. et al., all prior-art grounds remain potentially available for a future PTAB challenge.

The filing of IPR2026-00245 by FanDuel, Inc. et al. against Winview IP Holdings LLC indicates a potential dispute in the gaming and programming synchronization space. The current assignee, Winview IP Holdings LLC, is identified, and Unified Patents is noted as the source for the PTAB data, indicating their involvement in tracking or possibly initiating these types of challenges. This pattern suggests an active interest in challenging patents in this area, but as only one proceeding is listed, it's premature to conclude an aggressive pattern of IPR filings or appeals from the patent owner.

Recommended next steps

• Since IPR2026-00245 is pending institution, the next key milestone for this proceeding is the institution decision, expected around 2026-08-03. Monitoring this decision will be critical. If instituted, the full scope of challenged claims and prior art will become clear.
• It is advisable to obtain and review the petition for IPR2026-00245 to understand the specific claims being challenged and the prior art asserted against them. This would inform potential defenses or counter-arguments if facing assertion of this patent.
• Continue monitoring the USPTO PTAB E2E system for updates on IPR2026-00245, specifically for the institution decision and any subsequent trial stages.
