PTAB challenges

Proceedings overview

There are two AIA trial proceedings on file for US patent 8104492, both of which are Inter Partes Reviews (IPRs) filed by Treasure Garden, Inc. Both IPRs, IPR2025-01006 and IPR2025-01005, reached a status of "Discretionary Denial" as of November 24, 2025. This means that the PTAB declined to institute review of the challenged claims in both cases, leaving all claims of the patent intact. From a defendant's perspective, this indicates the patent has survived two IPR challenges, making future IPR-based defenses potentially more difficult, especially if based on similar grounds.

IPR2025-01006 — Treasure Garden, Inc. v. ATLEISURE LLC

• Type: Inter Partes Review
• Filed: 2025-05-22
• Status: Discretionary Denial — The PTAB declined to institute an IPR trial.
• Judge panel: Information not publicly available without specific PTAB docket access for this procedural status.
• Petition grounds: The specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103) are not publicly available in detail for a discretionary denial without accessing the full petition and decision documents. However, given the nature of IPRs, it would typically involve challenges to claims 1-7 based on anticipation and/or obviousness over prior art patents or publications.
• Institution decision: Denied (discretionary) — The PTAB issued a decision declining institution as of a date prior to the "last modified" date of 2025-11-24. The reasoning for a discretionary denial often relates to factors like parallel district court litigation, advanced stage of litigation, or inefficient use of PTAB resources, rather than the merits of patentability.
• Final Written Decision: Not issued, as institution was denied.
• Settlement / termination: The proceeding was terminated by discretionary denial, not settlement.
• Appeal: No appeal to the Federal Circuit, as no Final Written Decision was issued.
• Defensive value: The discretionary denial means that the claims challenged in this petition remain patentable. Any future IPR challenging the same claims on the same or substantially similar grounds by the same petitioner (or those in privity) may face estoppel under 35 U.S.C. § 315(e)(1). For other potential defendants, the exact grounds raised are unknown without the petition, but the fact that institution was denied suggests that a different IPR strategy (e.g., different prior art, different claims) might be necessary.

IPR2025-01005 — Treasure Garden, Inc. v. ATLEISURE LLC

• Type: Inter Partes Review
• Filed: 2025-05-22
• Status: Discretionary Denial — The PTAB declined to institute an IPR trial.
• Judge panel: Information not publicly available without specific PTAB docket access for this procedural status.
• Petition grounds: The specific claims challenged, prior art asserted, and statutory bases (§ 102 / § 103) are not publicly available in detail for a discretionary denial without accessing the full petition and decision documents.
• Institution decision: Denied (discretionary) — The PTAB issued a decision declining institution as of a date prior to the "last modified" date of 2025-11-24. Similar to IPR2025-01006, the reasoning for a discretionary denial likely involved procedural or policy considerations rather than a full merits review.
• Final Written Decision: Not issued, as institution was denied.
• Settlement / termination: The proceeding was terminated by discretionary denial, not settlement.
• Appeal: No appeal to the Federal Circuit, as no Final Written Decision was issued.
• Defensive value: All claims challenged in this IPR remain patentable. Similar to IPR2025-01006, the petitioner (or those in privity) may be estopped from raising the same or substantially similar grounds in future proceedings. This outcome strengthens the patent owner's position against IPR challenges using the grounds presented in this petition.

Strategic summary

As a result of these two IPRs, all claims (1-7) of US8104492 remain sustained and untested on the merits by the PTAB. Neither IPR reached the institution stage where the patentability of the claims would have been substantively reviewed. Both IPR2025-01006 and IPR2025-01005 were met with "Discretionary Denial," meaning the PTAB decided not to institute a trial for reasons typically related to judicial efficiency or parallel proceedings, rather than a determination of patentability on the merits.

The estoppel landscape for Treasure Garden, Inc. (and its privies) under 35 U.S.C. § 315(e)(1) is that they are likely barred from raising any ground that was raised or reasonably could have been raised in these petitions in future USPTO proceedings or district court litigation. For a defendant not in privity with Treasure Garden, Inc., all prior-art grounds, including those that might have been raised in the denied petitions, are theoretically still available for a new IPR petition, as the PTAB did not make a merits-based finding on patentability.

A clear pattern signal is that Treasure Garden, Inc. filed two IPRs concurrently (both filed on 2025-05-22), indicating a concerted effort to challenge the patent. The discretionary denial, rather than a merits-based decision, suggests that the PTAB may have applied its Fintiv factors or similar discretionary considerations, possibly due to ongoing district court litigation involving the same parties and patent. The current assignee, ATLEISURE LLC, successfully defended against these two IPR petitions by securing discretionary denials.

Recommended next steps

For a potential defendant, since both IPRs resulted in discretionary denials and no claims were invalidated, there are no specific Final Written Decisions to link to for claim cancellation. The patent, with all claims intact, retains its full scope for assertion.

Given the discretionary denials, a potential defendant considering an IPR would need to carefully assess the reasons for denial in IPR2025-01006 and IPR2025-01005. If these denials were based on Fintiv factors (i.e., considerations of parallel district court litigation), any new IPR petition should attempt to distinguish itself by, for example, being filed earlier in any parallel litigation, presenting compelling new prior art, or challenging different claims. A thorough review of the public records for these IPRs (which would require access to the PTAB's End-to-End (E2E) system for the institution decisions) would be essential to understand the specific reasoning behind the discretionary denials and to formulate an effective strategy.

If no new PTAB activity is initiated, the patent remains unadjudicated on the merits at the PTAB.
