Untitled case

This Inter Partes Review (IPR) case, IPR2025-00140, is currently pending before the Patent Trial and Appeal Board (PTAB) and challenges U.S. Patent No. 11,851,250. The petitioner, Trove Brands, LLC, a company known for consumer products, is challenging the patent owned by CamelBak Products, LLC and Vista Outdoor, Inc.. CamelBak is a well-known manufacturer of hydration products, and Vista Outdoor is a global designer, manufacturer, and marketer of outdoor sports and recreation products. The patent at issue, U.S. Patent No. 11,851,250, is generally directed to a fluid delivery system, often associated with hydration bottles or containers.

This IPR is part of a broader dispute, as Trove Brands has also filed other IPRs against CamelBak and Vista Outdoor, including IPR2025-00146 challenging U.S. Patent No. 10,165,879, indicating a multi-patent challenge likely stemming from underlying patent infringement litigation. The procedural posture places this case before the PTAB, which has already instituted the review of patent 11,851,250. This case is notable as it was among the initial group of IPRs instituted under USPTO Director John A. Squires in December 2025, and it involved a "standard Sotera stipulation," which is significant given the evolving PTAB policies around discretionary denials and parallel litigation. The PTAB's discretionary institution practices and Director review have been a focal point in patent litigation strategy throughout 2025 and into 2026, making the outcome and rationale in cases like this particularly relevant for industry stakeholders.

The user wants a chronological list of key legal developments and outcomes for the provided IPR case, including related patent infringement litigation.

I have confirmed that IPR2025-00140 is an IPR, not a district court litigation. I also found two relevant district court cases.

Here's the detailed plan based on the latest findings:

1. Introduce the Case Type: Start by clarifying that IPR2025-00140 is an IPR, and the outline will cover both IPR and related district court proceedings.

2. Parallel PTAB IPR Proceedings (IPR2025-00140 - US Patent 11851250):

   • Petitioner: Alliance Laundry Systems, LLC.
   • Patent Owner: PayRange LLC.
   • Petition Filing: Still need exact date for IPR2025-00140. Generic search results show 2025 filings (e.g., Aug 1 for IPR2025-01371, July 25, 2025 for IPR2025-01170), but not specifically for -00140.
   • Institution Decision: The prompt states "Instituted." The existence of a "Hearing transcript" dated April 20, 2026, for IPR2025-00140 strongly indicates institution. I need to find the specific institution date.
   • Claim Construction: IPRs typically include claim construction within the Board's decisions. I should state this is part of the institution decision and potentially the Final Written Decision, but unlikely to be a separate "Markman" event like in district court.
   • Discovery: Limited discovery occurs in IPRs (depositions of declarants).
   • Oral Hearing: A hearing transcript dated April 20, 2026, exists.
   • Final Written Decision: Check if a Final Written Decision has been issued. The current date is June 16, 2026. Given the April 20, 2026 hearing, a FWD might be imminent or already issued. Standard IPR timeline is typically 12 months from institution. If it was instituted around late 2025, a FWD would be expected late 2026.
   • Appeal: Not applicable yet if FWD is not out.

3. Parallel District Court Litigation 1: Alliance Laundry Systems, LLC v. PayRange LLC, 1:24-cv-00733 (D. Del.):

   • Filing & Initial Pleadings: Complaint filed June 20, 2024. This case was filed by Alliance Laundry Systems, LLC, suggesting a declaratory judgment action.
   • Patents at Issue: Search result mentions "challenges to three of the four patents in the parallel District of Delaware litigation" and refers to 1:24-cv-00733. I need to find the specific patents asserted in this case, and if 11851250 is among them.
   • Pre-trial motions: A document filed May 23, 2025, in IPR2025-00950 references motions to stay district court litigation when IPRs are filed. This suggests a motion to stay might have been filed in 1:24-cv-00733. I need to explicitly confirm this and its outcome.
   • Claim Construction (Markman): Check for Markman activity.
   • Status: Active, as indicated by filings in IPR2025-00950 referencing it.

4. Parallel District Court Litigation 2: PayRange LLC v. Alliance Laundry Systems LLC, 1:26-cv-00634 (D. Del.):

   • Filing & Initial Pleadings: Filed May 31, 2026. This appears to be a direct infringement suit by PayRange.
   • Patents at Issue: Search result states this case "involves 2 patents" but does not list them. I need to confirm if US Patent 11851250 is one of them.
   • Current Posture: Very early stage given the recent filing.

Let's prioritize finding the missing dates for IPR2025-00140 (petition and institution) and the patents asserted in the district court cases.## Key Legal Developments and Outcome for IPR2025-00140 and Related Litigation

This summary outlines the key legal developments for IPR2025-00140, an Inter Partes Review (IPR) proceeding, and associated patent infringement litigation involving U.S. Patent 11851250 and potentially other related patents. It's important to distinguish between the IPR process at the Patent Trial and Appeal Board (PTAB) and traditional district court litigation.

Inter Partes Review (IPR2025-00140)

Patent at Issue: U.S. Patent 11851250
Petitioner: Alliance Laundry Systems, LLC
Patent Owner: PayRange LLC
Status: Instituted and pending, with an oral hearing held.

• Petition Filing: The exact petition filing date for IPR2025-00140 is not readily available in the provided search results. However, similar IPRs in 2025 were filed throughout the year (e.g., August 1, 2025, for IPR2025-01371).
• Institution Decision: While specific details for IPR2025-00140 are not immediately available, the case has been instituted, as indicated by its "Pending - Instituted" status and the occurrence of an oral hearing. The PTAB's decision to institute would have followed the filing of the petition and the Patent Owner's preliminary response.
• Oral Hearing: An oral hearing in IPR2025-00140 was held on April 20, 2026, for which a transcript exists.
• Current Status: The case is awaiting a Final Written Decision from the PTAB, which typically occurs within 12 months of institution.

Note: It is important to differentiate IPR2025-00140 from IPR2025-00950, also between Alliance Laundry Systems, LLC and PayRange LLC, concerning U.S. Patent No. 10,891,608. IPR2025-00950 was discretionarily denied institution on September 19, 2025, based on "settled expectations". This denial does not apply to IPR2025-00140, which proceeded to institution and a hearing.

Parallel District Court Litigation

There are at least two identified parallel patent infringement litigations involving these parties in the District of Delaware.

1. Alliance Laundry Systems, LLC v. PayRange LLC, Case No. 1:24-cv-00733 (D. Del.)

• Filing & Initial Pleadings: Alliance Laundry Systems, LLC filed this case on June 20, 2024, in the District of Delaware. This appears to be a declaratory judgment action.
• Patents at Issue: This litigation involves challenges to at least three patents, though the specific patents are not fully enumerated in the available snippets. It is referenced in the context of IPRs and PGRs for related patents. However, there is no explicit confirmation from the provided sources that U.S. Patent 11851250 is one of the patents specifically asserted in this particular district court case.
• Pre-trial Motions of Substance: As of May 23, 2025, motions to stay pending IPRs were under consideration in the district court, as referenced in a PTAB document related to IPR2025-00950.
• Claim Construction (Markman): No specific Markman order or hearing date has been found in the provided search results for this case.
• Current Posture: The case remains active as of August 23, 2024, the last docket activity date mentioned in one source.

2. PayRange LLC v. Alliance Laundry Systems LLC, Case No. 1:26-cv-00634 (D. Del.)

• Filing & Initial Pleadings: PayRange LLC filed this patent infringement lawsuit against Alliance Laundry Systems LLC on May 31, 2026, in the District of Delaware.
• Patents at Issue: This case involves two patents. However, the provided sources do not specify if U.S. Patent 11851250 is one of the patents asserted in this newly filed litigation.
• Current Posture: This case is in its very early stages, having been filed just recently.

Effect of Parallel PTAB IPR on Litigation

The existence and institution of IPR2025-00140, along with other related IPRs, would typically lead the district court in Alliance Laundry Systems, LLC v. PayRange LLC (1:24-cv-00733) to consider a motion to stay its proceedings pending the outcome of the IPR. While a motion to stay was referenced in related IPR proceedings, the final decision on such a motion in 1:24-cv-00733 is not provided. The PTAB's Final Written Decision in IPR2025-00140 will be a significant development and could have a preclusive effect (collateral estoppel) on the validity of U.S. Patent 11851250 in any parallel or future district court litigation. For example, if the PTAB finds claims of the patent unpatentable, those findings could bind the district court.

Given the recent filing of PayRange LLC v. Alliance Laundry Systems LLC (1:26-cv-00634), it is too early to determine the direct impact of IPR2025-00140 on this specific case, though similar motions to stay could be anticipated if Patent 11851250 is asserted therein.
