PTAB challenges

Proceedings overview

One AIA trial proceeding is on file for US patent 12258111, with a status of Institution Denied. This indicates that the patent has not been challenged on the merits at the PTAB, and all claims remain untested by post-grant review. For a defendant, this means the patent's claims are currently fully intact, and any prior art-based defense will need to be pursued through other avenues (e.g., district court litigation or a new PTAB petition).

PGR2025-00089 — Shuttleslide, LLC v. Sea Swivel Inc

• Type: Post-Grant Review
• Filed: 2025-09-25
• Status: Institution Denied – The Patent Trial and Appeal Board (PTAB) declined to institute a trial based on the petition.
• Judge panel: Judge Stephen C. Siu, Judge Brian J. McNamara, and Judge Eric K. Threet.
• Petition grounds: The petition challenged claims 1-7 of US12258111 on grounds of lack of written description (§ 112, first paragraph) and obviousness (§ 103) over various combinations of prior art, including US Patent 6,053,471 (Brown), US Patent 5,607,136 (RTA), and US Patent 2010/0242828 (Gratsch).
• Institution decision: Denied on 2026-04-17. The panel found that the petition failed to establish a reasonable likelihood that claims 1-7 were unpatentable. Specifically, the Board determined that Shuttleslide, LLC did not meet its burden to show that the challenged claims lacked adequate written description and did not adequately demonstrate obviousness based on the cited prior art combinations.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable.
• Appeal: No Federal Circuit appeal has been initiated as institution was denied.
• Defensive value: The denial of institution for this PGR means that claims 1-7 have withstood a preliminary challenge at the PTAB. Any future PTAB challenge against these specific claims based on the same or substantially the same grounds would face a high hurdle due to the Board's previous reasoning, though it doesn't preclude a district court challenge.

Strategic summary

All 18 claims of US patent 12258111 remain UNTESTED at the PTAB. The single Post-Grant Review (PGR2025-00089) filed by Shuttleslide, LLC challenging claims 1-7 was denied institution by the PTAB. This means the merits of the patentability of these claims were not fully adjudicated in a trial. The remaining claims (8-18) were not challenged in this petition and are also untested by the PTAB.

Since the petition was denied institution, the statutory estoppel provisions of § 325(e)(2) for PGRs do not apply. This means that Shuttleslide, LLC (and any party in privy with them) is not barred from asserting any invalidity ground against claims 1-7 in a subsequent district court proceeding, nor would they be barred from filing a new PTAB petition on different grounds or with new art, subject to applicable deadlines and discretionary factors. For a defendant currently being asserted against, this implies that the prior art grounds raised in PGR2025-00089 (including US Patent 6,053,471, US Patent 5,607,136, and US Patent 2010/0242828) are still available to be raised in district court litigation or potentially in a new PTAB petition, assuming statutory and regulatory requirements are met.

The activity shows a single petitioner, Shuttleslide, LLC, attempting to challenge the patent. The patent owner, Sea Swivel Inc, successfully defended against the institution of this PGR. There is no indication of a defensive aggregator like Unified Patents in this specific proceeding.

Recommended next steps

For a defendant facing assertion of US12258111, the primary outcome from the PTAB is that claims 1-7 have survived an institution challenge in PGR2025-00089. This means that the PTAB did not find a reasonable likelihood of unpatentability for these claims based on the arguments and evidence presented in the petition.

If you are a defendant, you should carefully review the "Institution Decision" for PGR2025-00089 to understand the specific reasoning for the denial. This decision can be found on the USPTO PTAB E2E system by searching for case number PGR2025-00089. The decision outlines the deficiencies in the petitioner's arguments regarding written description and obviousness. Understanding these deficiencies is crucial for assessing the strength of any new invalidity arguments you might consider.

As no PTAB trial has been instituted, all claims of US12258111 remain legally presumptively valid from a PTAB perspective. If a defendant wishes to challenge the patentability of the claims, they would need to consider filing a new IPR or PGR petition, being mindful of the Board's reasoning in the denied institution decision for PGR2025-00089 and the relevant statutory deadlines for such filings. Alternatively, invalidity arguments could be pursued in federal district court litigation.

There are no active proceedings pending, meaning no further trial-stage milestones are anticipated from the current PTAB record.
