InnoMemory v. Axiomtek: Memory Refresh Patent Suit Dismissed With Prejudice
InnoMemory, LLC asserted US7057960B1 — a patent covering power-reduction methods for memory device refresh operations — against Axiomtek Co., Ltd. in the Eastern District of Texas. The case ended with a voluntary dismissal with prejudice after 274 days, closing all claims permanently and leaving each party to bear its own legal costs.
E.D. Tex. Memory Patent Suit Ends Before Substantive Merits Ruling
On August 19, 2024, InnoMemory, LLC filed a patent infringement action against Axiomtek Co., Ltd. in the United States District Court for the Eastern District of Texas (Case No. 2:24-cv-00681). The asserted patent, US7057960B1, covers a method and architecture for reducing power consumption in memory devices during refresh operations — a technically significant area given the pervasive use of DRAM and similar memory in computing and embedded systems products of the kind Axiomtek manufactures.
The case closed on May 20, 2025, when InnoMemory filed a Notice of Dismissal under Rule 41(a)(1)(A)(i), voluntarily dismissing all claims with prejudice. The court accepted and acknowledged the notice, formally dismissed all pending claims and causes of action with prejudice, and denied all other pending relief as moot. Critically, the order specifies that each party shall bear its own costs, expenses, and attorneys’ fees — suggesting no settlement payment was memorialised in the court record.
At 274 days, the case resolved without any substantive ruling on infringement, validity, or claim construction — consistent with an early-stage resolution before significant litigation milestones such as Markman proceedings. The dismissal with prejudice is notably stronger than a voluntary dismissal without prejudice, permanently barring InnoMemory from reasserting the same claims against Axiomtek on US7057960B1. The underlying commercial terms, if any, remain undisclosed on the public docket.

Dismissed with prejudice: what the Rule 41 order means for both parties
Rule 41(a)(1)(A)(i): plaintiff-initiated dismissal with prejudice
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case before the defendant serves an answer or motion for summary judgment. When the notice specifies ‘with prejudice,’ the dismissal operates as a final adjudication on the merits — permanently extinguishing the plaintiff’s right to re-file the same claims against the same defendant on the same patent.
Permanent bar on re-filingInnoMemory permanently relinquishes its claims against Axiomtek
By filing with prejudice, InnoMemory has permanently surrendered its ability to reassert US7057960B1 against Axiomtek in any future action. This is a materially stronger concession than a without-prejudice dismissal. Whether a confidential licence or other commercial arrangement underpins this outcome is not disclosed on the public docket — the order is silent on any payment or cross-licence.
Claims extinguishedAxiomtek secures permanent closure — no invalidity ruling obtained
Axiomtek, represented by Jones Day, achieves finality against this specific assertion without a court ruling on infringement or validity. While Axiomtek is shielded from future InnoMemory claims on US7057960B1, the patent itself remains in force and could be asserted against other defendants. Axiomtek bears its own legal costs with no fee-shifting award.
Protected from re-assertionUS7057960B1 survives — third parties remain exposed
Because the dismissal resolves only the dispute between InnoMemory and Axiomtek, US7057960B1 retains full legal force. Other companies in the embedded computing, industrial hardware, or memory-intensive device space who have not obtained a licence or favourable ruling remain potentially exposed to assertion. The lack of any claim construction or validity decision means the patent’s scope is untested in litigation.

Official order — verbatim text
The court’s order tracks InnoMemory’s notice precisely, accepting the with-prejudice designation and invoking Rule 41(a)(1)(A)(i) — a provision requiring no court approval when filed before a defendant’s responsive pleading. The explicit denial of all other pending relief as moot, combined with the own-costs directive, indicates no fee-shifting motion had advanced far enough to survive. No substantive finding on infringement, validity, or claim scope was made, leaving US7057960B1 legally intact for assertion elsewhere.
US7057960B1 — Memory Device Power Reduction in Refresh Operations
US7057960B1 (Application No. US10/629667) is a granted US utility patent covering a method and architecture specifically designed to reduce power consumption in memory devices during refresh operations. Refresh cycles are a fundamental and power-intensive requirement of volatile memory such as DRAM — the patent addresses the energy cost of these unavoidable operations, making it relevant to any system where memory endurance and thermal management are design constraints, including embedded computing, industrial hardware, and IoT platforms.
From a strategic perspective, power-efficient memory refresh sits at the intersection of semiconductor design and embedded systems — a space occupied by a wide range of hardware OEMs, SoC vendors, and industrial computing companies. A patent assertable against a company like Axiomtek, which produces embedded boards and systems incorporating commercial DRAM, suggests broad potential applicability across the sector. The patent’s continued enforceability post-dismissal makes it a live risk factor for any competitor operating in this technology space without a licence or design-around.
Should your engineering team run an FTO against US7057960B1?
Any company designing or commercialising products that incorporate DRAM or other volatile memory with refresh cycles — including embedded computing boards, industrial PCs, edge computing modules, or memory controllers — should consider whether US7057960B1 reads on their architecture. The patent’s focus on refresh-phase power reduction means it is most relevant to teams working on power-optimised memory subsystems, low-power embedded designs, or products targeting energy-constrained deployment environments.
PatSnap Eureka’s FTO Search Agent can map the claim language of US7057960B1 against your product’s memory architecture, identify prior art that could inform an invalidity argument, and surface related continuations or family members that may present parallel risk. Given that this patent has never received judicial claim construction, an FTO grounded in rigorous claim charting is especially valuable before any product launch or investment decision in this technology area.

What this case signals for the embedded memory IP landscape
A with-prejudice dismissal in E.D. Tex. before any substantive ruling leaves the patent’s enforceability intact — and industry exposure unresolved.
With-prejudice dismissals signal finality — but only for the named defendant
InnoMemory’s choice to dismiss with prejudice under Rule 41(a)(1)(A)(i) permanently bars reassertion against Axiomtek. However, US7057960B1 remains active and enforceable. Any other embedded computing or memory device manufacturer should treat this outcome as a signal to audit their own exposure rather than evidence that the patent is invalid or unenforceable.
E.D. Tex. remains a preferred venue for memory and semiconductor patent assertions
The Eastern District of Texas continues to attract patent infringement filings in the semiconductor and memory device space. Early resolution — here, without a Markman hearing — is increasingly common when defendants engage experienced counsel quickly. Axiomtek’s retention of Jones Day suggests a well-resourced defence posture that may have contributed to the swift resolution.
InnoMemory v Axiomtek — key questions answered
The with-prejudice dismissal permanently bars InnoMemory from reasserting the same claims under US7057960B1 against Axiomtek. However, it does not invalidate the patent or prevent assertion against other defendants. Third parties in the embedded computing and memory device space remain exposed to potential infringement claims on US7057960B1.
US7057960B1 covers a method and architecture for reducing power consumption in memory devices specifically during refresh operations. Refresh cycles are an inherent requirement of volatile memory such as DRAM, and the patent addresses power optimisation in that process — making it relevant to embedded systems, industrial computing, and any product incorporating power-sensitive memory subsystems.
The case closed after only 274 days, before any substantive milestones such as claim construction or summary judgment. InnoMemory filed a Rule 41(a)(1)(A)(i) notice of voluntary dismissal with prejudice, which does not require court approval at that procedural stage. The public record does not disclose why InnoMemory chose to dismiss — potential explanations include a confidential settlement, licensing resolution, or strategic reassessment.
The own-costs order means neither party obtained a fee-shifting award under 35 U.S.C. § 285 (exceptional case) or Rule 54. This is consistent with early voluntary dismissal before any substantive litigation conduct could support an exceptional-case finding. It does not confirm or deny whether a confidential payment was made between the parties outside the court record.
Yes. The dismissal with prejudice resolves only the dispute between InnoMemory and Axiomtek and contains no ruling on validity or enforceability. US7057960B1 remains a granted, enforceable US patent. Companies designing memory systems or embedded computing products that incorporate DRAM refresh architectures should conduct freedom-to-operate analysis to assess their exposure.
