Untitled case

Unified Patents, a member-based organization focused on deterring what it deems "frivolous patent litigation" by Non-Practicing Entities (NPEs), initiated an Inter Partes Review (IPR) against U.S. Patent No. 11,347,657 before the Patent Trial and Appeal Board (PTAB). The patent is owned by Radian Memory Systems LLC, a company that develops software-defined flash technology aimed at enhancing data storage performance and efficiency. Radian Memory Systems LLC has been characterized as an NPE in related district court proceedings, and its business model involves licensing its patented technology, particularly concerning improved management of flash solid-state drives (SSDs). In the IPR, Unified Patents was joined by Samsung Electronics America Inc. and Samsung Electronics Co. Ltd., indicating that Samsung was likely a target of Radian's patent assertions.

The patent at issue, U.S. Patent No. 11,347,657, generally relates to "Symphonic Cooperative Flash Management" technology for solid-state drives. This technology aims to improve how flash memory is managed in SSDs, particularly in data center and enterprise operations, by replacing the traditional Flash-Translation-Layer (FTL) with a cooperative management system involving host-side software libraries and SSD firmware. This approach seeks to deliver better performance, reduce costs, and extend the endurance of flash storage. The IPR was filed at the Patent Trial and Appeal Board (PTAB), a specialized administrative tribunal within the U.S. Patent and Trademark Office (USPTO) that reviews the patentability of claims in issued patents based on prior art. The case ultimately reached a settlement between the parties.

This case is notable for several reasons. It exemplifies Unified Patents' strategy of challenging patents asserted by NPEs, particularly those impacting large operating companies like Samsung in critical technology sectors such as computer architecture, software, and information security. Furthermore, this IPR was linked to parallel patent infringement litigation filed by Radian Memory Systems LLC against Samsung in the Eastern District of Texas (Civil Action No. 2:24-cv-01073). That district court case garnered significant attention when the U.S. Department of Justice (DOJ) and the USPTO filed a rare Statement of Interest, arguing against categorical denials of injunctive relief for NPEs and highlighting the challenges of calculating monetary damages for patent infringement. While Radian's preliminary injunction motion in the district court was later withdrawn, the government's intervention underscored the broader policy debate surrounding NPEs and patent remedies, making the IPR's settlement a resolution to a multi-faceted dispute across different legal venues.

IPR2025-01378: Key Legal Developments and Outcome

This analysis details the key legal developments and outcome for IPR2025-01378, an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB) concerning U.S. Patent No. 11,347,657. The case, initiated by Unified Patents, concluded in a settlement.

Filing & Initial Pleadings

The Inter Partes Review petition, IPR2025-01378, challenging U.S. Patent No. 11,347,657, was filed on August 5, 2025. While the case metadata identifies Unified Patents as the plaintiff, specific PTAB records for IPR2025-01378 list Samsung Electronics America Inc. and Samsung Electronics Co. Ltd. as the Petitioners. The Patent Owner for the challenged patent is Radian Memory Systems LLC.

Pre-Institution and Settlement

The case reached a settlement, with a termination date recorded as December 30, 2025. In an IPR, a settlement can occur at various stages, including before the PTAB decides whether to institute the review. The prompt's indication of "Settlement" as the status and the short timeframe between filing and termination suggest that the parties likely settled prior to a formal institution decision being issued by the PTAB, thereby avoiding a full trial at the Board.

Final Disposition

The final disposition of IPR2025-01378 was a settlement. This outcome means the parties resolved their dispute regarding the patent outside of a contested PTAB trial and final written decision. Settlements are a common occurrence in IPR proceedings, with the PTAB reporting varying settlement rates for IPRs.

Parallel PTAB IPR/PGR Proceedings

This case itself is a PTAB IPR proceeding. No other parallel PTAB IPR or Post-Grant Review (PGR) proceedings on U.S. Patent No. 11,347,657 were identified in the available information. The settlement effectively resolved the challenge to patent 11,347,657 within the context of this IPR.

Inapplicable Litigation Stages

It is important to note that many of the requested elements for patent infringement litigation, such as answers, counterclaims, pre-trial motions (like motions to dismiss, transfer, or summary judgment in a district court context), claim construction (Markman) outcomes, discovery milestones, trial events, verdicts, and post-trial motions (JMOL, new trial, fees), are not directly applicable to an IPR proceeding, especially one that concluded in a settlement prior to a full trial. An IPR is an administrative process focused on the patentability of claims based on prior art, rather than a full-scale infringement lawsuit.

Unified Patents, as a petitioner in Inter Partes Review (IPR) proceedings, often utilizes a combination of in-house counsel and external law firms to represent them before the Patent Trial and Appeal Board (PTAB). While the specific counsel of record for IPR2025-01378 (U.S. Patent No. 11,347,657) is not explicitly detailed in publicly available summaries without direct access to the case's docket, general information regarding Unified Patents' legal representation in IPRs can be inferred from their typical practices and past cases.

Unified Patents employs a team of in-house Senior Patent Counsel who are actively involved in managing and litigating patent office proceedings, including drafting IPR petitions, motions, and briefs. These in-house attorneys often have extensive experience with PTAB proceedings.

When Unified Patents engages outside counsel, firms specializing in patent litigation and PTAB practice are typically retained. For example, in IPR2021-01260, Unified Patents was represented by attorneys from Erise IP, P.A. as lead and back-up counsel, alongside Unified Patents' own in-house counsel.

Based on this, the counsel for Unified Patents in IPR2025-01378 would likely consist of:

• In-house counsel from Unified Patents: These attorneys, such as Senior Patent Counsel, would manage the proceedings internally and contribute to the legal strategy and filings. Members of their current team with PTAB experience include Jonathan Stroud (COO & CLO), Jenn Bisk, Kyla Bulter, Kelly Hughes, T.J. Murphy, Vinu Raj, Jordan Rossen, Andrea Shoffstall, David Seastrunk, and Jason Wejnert. Jordan Rossen and Roshan Mansinghani (Head of Operations) have been listed as backup counsel for Unified Patents in other IPRs.
• Outside counsel from a law firm specializing in PTAB litigation: These firms provide specialized expertise and resources for drafting and litigating the IPR petition. In prior cases, Erise IP, P.A. attorneys Jason R. Mudd, Kelly R. Hughes, and Eric A. Buresh have served as lead and backup counsel for Unified Patents in IPRs.

To identify the exact counsel for IPR2025-01378, one would need to consult the specific "Power of Attorney" or initial petition filings within the PTAB's electronic filing system for that case number. Without direct docket access for this specific IPR, the precise names and roles of the attorneys involved cannot be definitively stated at this time.

This case is an Inter Partes Review (IPR) before the Patent Trial and Appeal Board (PTAB), not a traditional patent infringement case. In an IPR, Unified Patents is the "Petitioner," and the entity defending the patent is the "Patent Owner." The request for counsel representing the "defendant(s)" will be interpreted as a request for counsel representing the Patent Owner in IPR2025-01378.

Due to the nature of PTAB proceedings, specific counsel information for IPR2025-01378, particularly for the Patent Owner, is not readily available through general web searches without direct access to the PTAB's End-to-End (E2E) system or specific docket filings. The available search results discuss Unified Patents' internal legal team and provide general statistics on law firms frequently involved in PTAB cases, but do not pinpoint the specific counsel for the Patent Owner in IPR2025-01378.

As the filings for IPR2025-01378 are not publicly accessible through the conducted web searches, the counsel of record representing the Patent Owner cannot be identified at this time. Without direct access to the PTAB docket for this specific case, it is not possible to provide the names, roles, firms, or experience of the Patent Owner's attorneys.
