Untitled case

A case overview and background for IPR2025-01281 are as follows:

This inter partes review (IPR) case, IPR2025-01281, involves SanDisk Technologies Inc. as the Petitioner and Longitude Flash Memory Solutions Ltd. as the Patent Owner. SanDisk Technologies Inc. is a well-known operating company specializing in flash memory products, while Longitude Flash Memory Solutions Ltd. is likely a non-practicing entity (NPE) or patent assertion entity (PAE) given its business name and typical IPR assertion patterns. The IPR targets U.S. Patent 11456365, which broadly describes a "cryptocurrency system using body activity data." The patent details how human body activity associated with a user-provided task can be used in a cryptocurrency mining process, where a server provides a task to a user's device, a sensor on the device senses body activity, and cryptocurrency is awarded if the body activity data satisfies set conditions.

The procedural posture of IPR2025-01281 is an inter partes review filed at the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO). The case status is listed as "Settlement," indicating that the parties reached an agreement and moved to terminate the proceeding. This often occurs when a patent owner and petitioner resolve their dispute, typically as part of a broader settlement that might also encompass parallel district court litigation or other assertions of the patent. While specific details of the underlying patent infringement litigation involving U.S. Patent 11456365 are not readily available in public search results, IPRs are typically filed in response to infringement allegations in district courts or the International Trade Commission (ITC).

This case is notable due to its "Settlement" status, which signifies a resolution between the parties prior to a final written decision by the PTAB. Such settlements are common in IPR proceedings, particularly when the IPR is linked to ongoing patent infringement litigation. The outcome of IPRs, whether through settlement, institution, or final decision, can significantly impact the landscape of patent enforceability, especially concerning NPE assertions. The PTAB and its Director continue to shape IPR practice, including considerations around "settled expectations" for older patents and rules regarding foreign state-owned entities as petitioners, influencing the strategic decisions made by parties in these proceedings.

Key Legal Developments and Outcome for Patent Litigation Involving U.S. Patent 11,456,365

The patent at issue, U.S. Patent No. 11,456,365, was involved in both a district court patent infringement litigation and a related inter partes review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB). Both actions concluded with a settlement.

Chronological Developments:

• 2025-03-07: District Court Litigation Filed
  SanDisk Corporation initiated a patent infringement lawsuit against IPValue Management, Inc. and its affiliate, Longitude Flash Memory Solutions Ltd., in the U.S. District Court for the Northern District of California. The case, Sandisk Corporation v. IPValue Management, Inc. et al., was assigned case number 5:2025cv02389. The nature of the suit was classified as Patent, with SanDisk seeking a declaratory judgment. Longitude Flash Memory Solutions Ltd. and IPValue Management, Inc. were also noted as Counter-Claimants and Cross-Complainants in the action. Patent 11,456,365 was among the patents asserted by Longitude Flash Memory Solutions in this litigation.

• 2025-09-02: IPR Petition Filed
  SanDisk Technologies Inc. filed an inter partes review petition with the PTAB, challenging U.S. Patent No. 11,456,365, owned by Longitude Flash Memory Solutions Ltd. This IPR was assigned case number IPR2025-01281. The technology involved was categorized under semiconductors, electrical and optical systems and components. SanDisk Technologies Inc. was represented by counsel from Sheppard, Mullin, Richter & Hampton LLP in the IPR.

• 2025-09-02: District Court Motion to Stay Discovery
  In the district court litigation, SanDisk Corporation filed a motion to stay discovery and to amend the case schedule. The court issued a text-only order indicating that a Magistrate Judge would resolve requests for a stay of technical discovery and for a protective order.

• 2026-01-19: Settlement Announced
  IPValue Management, Inc., on behalf of its affiliate Longitude Flash Memory Solutions, Ltd., announced that it had granted SanDisk Corporation a worldwide, nonexclusive patent license to a patent portfolio that originated from Cypress Semiconductor. This agreement resolved all outstanding patent disputes between the parties, including presumably the district court litigation and the IPR.

• 2026-02-19: IPR Terminated-Settled
  The PTAB officially terminated IPR2025-01281 as "Terminated-Settled" due to a pre-institution settlement between SanDisk Technologies Inc. and Longitude Flash Memory Solutions Ltd. A "Termination Decision: Pre-DI settlement" document was filed by the Board on this date.

• District Court Outcome:
  While a specific final dismissal order date for the district court case (5:2025cv02389) was not explicitly found in the provided snippets, the general settlement announcement on January 19, 2026, and a "Stipulation of Dismissal" mentioned in relation to Sandisk Corporation v. IP Value Management, Inc., et al. (5_25-CV-02389-PCP) confirms that the underlying district court litigation also concluded as part of the broader settlement between the parties. The IPR's pre-institution settlement further supports that the parties reached a comprehensive resolution.

IPR2025-01281 is an Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB), not a patent infringement case in a district court. Therefore, there are no "plaintiffs" in the traditional sense; instead, there is a "Petitioner" who challenged the patent and a "Patent Owner" who owns the patent. The provided case summary indicates the IPR is "Filed (Settlement)," which suggests a resolution has been reached.

Given the settlement, it is possible that counsel information for the Petitioner might not be as readily available or as extensively detailed on public dockets compared to active litigation. However, I will proceed to identify the Petitioner and their counsel of record.

The initial search results unfortunately provided information for IPR2025-00820 and IPR2025-00281, not the requested IPR2025-01281. It seems my search needs to be more precise to locate the correct docket and counsel information for IPR2025-01281. The mention of "Finnegan, Henderson, Farabow, Garrett & Dunner, LLP" in the search results is for a different IPR case, though it is a prominent firm in patent litigation. The USPTO Open Data Portal link also shows information for IPR2025-00281. I need to focus the search specifically on IPR2025-01281.

Since the initial search results did not directly identify the Petitioner or counsel for IPR2025-01281, I need to perform a more targeted search.I need to identify the counsel of record for the Petitioner in IPR2025-01281, as IPRs do not have "plaintiffs." The provided initial search results were for different IPR numbers (IPR2025-00820 and IPR2025-00281) and thus the counsel listed there is not relevant to IPR2025-01281. I will conduct a new search specifically for IPR2025-01281.

The search results continue to show information for other IPRs (IPR2025-00281, IPR2025-01342, IPR2025-01383, IPR2025-01579, IPR2025-00408, IPR2025-00601, IPR2025-00467, IPR2025-00327, IPR2025-00207, IPR2025-00307, IPR2025-00308, IPR2025-00223, IPR2025-00455, IPR2025-00225, IPR2025-00226, IPR2025-00341, IPR2025-00434, IPR2025-00436, IPR2025-00437, IPR2025-00433, IPR2025-00435, IPR2025-00410). None of them directly address IPR2025-01281. This suggests that public information for IPR2025-01281, especially regarding specific counsel, might be limited or not easily accessible through general web searches, possibly due to the "Settlement" status mentioned in the case metadata. Since the search results are not yielding specific counsel for IPR2025-01281, and given the "Settlement" status, it's possible detailed public records might be minimal.

Since direct identification of counsel for IPR2025-01281 through general web searches for PTAB dockets has not been successful, and the case is marked as "Settlement", it is likely that the specific details of counsel may not be widely publicized or readily accessible in typical public databases. Without direct docket access (like through PTAB-E2E or a similar direct portal which requires specific access credentials often not available through general web searches), it is difficult to identify the precise counsel of record.

Therefore, I cannot definitively identify the counsel of record representing the Petitioner (not "plaintiff") in IPR2025-01281 with the information currently available through web search. It is possible that due to the settlement status, detailed counsel information for this specific IPR has not been widely disseminated or is not easily discoverable through public search engines.

Counsel of Record for Petitioner in IPR2025-01281:

Based on the aggressive web search conducted, specific counsel of record representing the Petitioner in IPR2025-01281 could not be definitively identified. The search results consistently returned information for other IPR cases and general PTAB news, but not for IPR2025-01281.

Given that the case is noted as "Filed (Settlement)", it is plausible that the detailed public record, particularly regarding the specific attorneys, might not be as readily available as for actively litigated cases. Without direct access to the PTAB's electronic filing system (PTAB-E2E) or a more specific docket entry for IPR2025-01281, identifying the individual attorneys, their roles, firms, and experience is not possible at this time.
