InnoMemory v. Lanner Electronics: Memory Patent Dismissed With Prejudice
InnoMemory, LLC filed suit against Lanner Electronics, Inc. in the Eastern District of Texas asserting US7057960B1, a patent covering power-reduction methods for memory device refresh operations. The parties jointly stipulated to dismissal with prejudice after 333 days, with each side bearing its own costs and attorneys’ fees.
Memory Power Patent Ends in Prejudicial Dismissal After E.D. Texas Filing
InnoMemory, LLC filed this patent infringement action on 19 August 2024 in the United States District Court for the Eastern District of Texas, asserting US7057960B1 against Lanner Electronics, Inc. The asserted patent covers a method and architecture for reducing power consumption in memory devices during refresh operations — a technically significant function in embedded computing and network appliance hardware, the type of product Lanner is known to manufacture.
The case closed on 18 July 2025 via a Joint Stipulation of Dismissal filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court accepted the stipulation and dismissed all claims and causes of action with prejudice. Each party was ordered to bear its own costs, expenses, and attorneys’ fees. The ‘with prejudice’ designation is legally consequential: InnoMemory is permanently barred from reasserting the same claims against Lanner on this patent.
At 333 days, the case resolved before any reported trial or dispositive ruling, consistent with a negotiated resolution reached after initial pleadings or early-stage proceedings. The mutual cost-bearing arrangement suggests neither party extracted a clear financial concession from the other, at least as reflected in the public record. Whether a licensing agreement or other commercial terms accompanied the dismissal is not disclosed in the court docket.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) — joint stipulation dismissal explained
A dismissal under Rule 41(a)(1)(A)(ii) requires signatures from all parties who have appeared, making it a consensual exit. Because it was entered ‘with prejudice,’ the dismissal carries the same preclusive effect as a final judgment on the merits. InnoMemory cannot re-litigate the same patent claims against Lanner in any federal court. This is the most final form of voluntary dismissal available.
Claim preclusion appliesInnoMemory permanently surrenders its claims against Lanner
By agreeing to dismissal with prejudice, InnoMemory forfeits any future right to assert US7057960B1 against Lanner Electronics on the same grounds. This outcome typically reflects either a licensing resolution reached off the public record, or a litigation-risk calculation that made continued prosecution commercially unviable. The mutual cost-bearing clause suggests InnoMemory did not extract a fee-shifting award.
No right to refileLanner secures permanent resolution — at its own legal cost
Lanner Electronics emerges with a final judgment-equivalent bar against further claims from InnoMemory on this patent. However, each party bearing its own costs means Lanner absorbed its own defense expenses without reimbursement. Whether Lanner obtained a license or simply defeated the claim commercially is not disclosed. The outcome provides certainty for Lanner’s product line going forward.
Full claim bar securedUS7057960B1 remains active — risk persists for other memory hardware makers
The dismissal with prejudice resolves only InnoMemory’s claims against Lanner. US7057960B1 itself is not invalidated and InnoMemory retains the right to assert it against other manufacturers of memory-intensive hardware. Companies producing embedded computing, network appliances, or server memory products should treat this patent as an ongoing enforcement risk and consider FTO analysis.

Official order — verbatim text
The court’s order accepts the parties’ joint stipulation verbatim and enters dismissal with prejudice as to all claims and causes of action in the member case. The explicit ‘with prejudice’ language — and the court’s directive to close the member case while maintaining the lead case — suggests this was part of a multi-defendant or consolidated proceeding. The cost-neutrality clause precludes fee-shifting arguments and indicates a negotiated resolution rather than a litigation win for either side.
US7057960B1 — Memory Device Power Reduction in Refresh Operations
US7057960B1, filed under application number US10/629667, covers a method and architecture for reducing the power consumption of memory devices during refresh operations. Memory refresh is a mandatory process in DRAM-based systems that periodically rewrites stored data to prevent degradation — it is power-intensive and continuous. The patent addresses optimisation of this cycle, a technically meaningful contribution in contexts where power budgets are constrained, such as embedded computing, network appliances, and edge hardware.
From a strategic standpoint, this patent sits at the intersection of memory efficiency and embedded systems — a domain that has grown significantly in commercial relevance as energy-efficient computing architectures become a design priority. Lanner Electronics, a manufacturer of network appliance hardware, is precisely the type of company whose products would incorporate DRAM subsystems subject to this patent’s claims. The patent’s continued validity post-dismissal means it represents an active assertion risk for any competitor operating in memory-intensive hardware markets.
Should your product team run an FTO against US7057960B1?
Any organisation designing or commercialising hardware that incorporates DRAM or DRAM-adjacent memory subsystems — including network appliances, embedded computing platforms, edge servers, and industrial computing systems — should treat US7057960B1 as a live FTO concern. The patent survived this litigation intact, and InnoMemory has demonstrated willingness to enforce it in E.D. Texas. Products featuring power-optimised memory refresh architectures are squarely within the patent’s potential claim scope.

What this case signals for the memory hardware IP landscape
Rapid joint dismissals in E.D. Texas patent cases often mask private licensing deals — the public record rarely tells the full story.
E.D. Texas remains a preferred venue for memory patent assertions
InnoMemory’s choice of the Eastern District of Texas is consistent with its reputation as a plaintiff-friendly venue for patent infringement actions. Hardware and memory technology patent holders continue to file here at elevated rates. Companies with products touching memory refresh architectures should monitor new filings in this district closely.
With-prejudice dismissals protect defendants but do not kill the patent
Lanner’s resolution creates a strong legal shield against InnoMemory specifically, but US7057960B1 remains valid and enforceable against the broader market. Other network appliance and embedded system vendors face the same assertion risk. A proactive FTO analysis of this patent is advisable for any company operating in adjacent product categories.
InnoMemory v Lanner — key questions answered
Dismissal with prejudice means all of InnoMemory’s claims against Lanner Electronics are permanently extinguished. InnoMemory cannot refile the same patent infringement claims based on US7057960B1 against Lanner in any federal court. The dismissal carries the same legal finality as a judgment on the merits, triggered here by a joint stipulation under Rule 41(a)(1)(A)(ii).
No. The patent was not adjudicated on its merits and was not declared invalid. The dismissal with prejudice extinguishes claims only as between InnoMemory and Lanner. US7057960B1 remains in force and InnoMemory retains the right to assert it against other defendants. Third-party hardware manufacturers should not treat this outcome as clearing the patent from the market.
The Eastern District of Texas is a consistently popular venue for patent assertion entities due to its established patent docket, historically plaintiff-friendly procedural norms, and experienced patent judiciary. InnoMemory’s choice of this district is consistent with broader filing patterns among non-practising entities asserting hardware and memory technology patents. The court also maintains a large lead-case/member-case docketing structure, consistent with multi-defendant enforcement campaigns.
US7057960B1 covers a method and architecture for reducing power consumption in memory devices during refresh operations — specifically addressing DRAM refresh cycle optimisation. Companies at risk include manufacturers of network appliances, embedded computing hardware, edge servers, and any product integrating DRAM subsystems with power-optimisation features. The patent’s claims are broad enough to warrant FTO analysis before product launch in these categories.
Under 35 U.S.C. § 285, exceptional patent cases can result in attorney fee awards to the prevailing party. The mutual cost-bearing clause in this dismissal forecloses any fee-shifting claim — neither InnoMemory nor Lanner will recover legal expenses from the other. This arrangement is commonly seen in negotiated patent resolutions and does not indicate which party, if any, made a financial payment as part of settling the underlying dispute.
