InnoMemory v. Kleberg Bank: Patent Suit Dismissed Without Prejudice in 45 Days
InnoMemory, LLC asserted US7057960B1 — covering power-reduction architecture for memory device refresh operations — against Kleberg Bank, National Association in the Southern District of Texas. The case closed in just 45 days when InnoMemory filed a voluntary dismissal without prejudice, leaving the door open for future action.
A 45-Day Patent Suit Against a Regional Bank That Left Questions Open
On February 2, 2025, InnoMemory, LLC filed a patent infringement action against Kleberg Bank, National Association in the U.S. District Court for the Southern District of Texas (Case No. 4:25-cv-00436), assigned to Judge Keith P. Ellison. The sole patent asserted was US7057960B1, directed to a method and architecture for reducing power consumption in memory devices during refresh operations — a technical domain typically associated with semiconductor and embedded systems design rather than financial services.
The case resolved in just 45 days: on March 19, 2025, InnoMemory filed a Notice of Voluntary Dismissal pursuant to Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure, and the court directed the clerk to close the case. The dismissal was entered without prejudice, meaning InnoMemory has not forfeited its right to reassert the same claims against Kleberg Bank or other defendants in a future action.
The 45-day duration and absence of any filed answer or substantive motion suggest the dismissal occurred before Kleberg Bank formally responded to the complaint — a procedural posture that permits Rule 41(a)(1) voluntary dismissal as of right. The public record does not disclose whether the parties reached a private settlement, whether InnoMemory encountered claim-mapping difficulties, or whether the filing was part of a broader licensing campaign. Those questions remain unanswered from available filings.
Filing to Voluntary dismissal in 45 days
45 days — well below the median district court patent case duration of 2+ years
Voluntarily dismissed without prejudice: what the ruling means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court approval needed
Under Rule 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case without a court order before the defendant serves an answer or a motion for summary judgment. The court’s order here confirms this procedural path: InnoMemory filed a Notice, and the court simply directed the clerk to close the file. No judicial merits determination was made. The patent’s validity and any alleged infringement remain legally unresolved.
No merits adjudicationWithout prejudice: the case can be refiled — but was it settled?
A dismissal without prejudice means InnoMemory retains the right to assert US7057960B1 against Kleberg Bank again, subject to any applicable statute of limitations. A dismissal with prejudice would have permanently barred refiling. The court order specifies ‘without prejudice,’ but the public record is silent on whether a private settlement was reached. Either an undisclosed agreement or a unilateral strategic withdrawal could explain the filing — both are consistent with this procedural outcome.
Refiling risk remainsKleberg Bank escapes judgment — but faces residual litigation risk
Kleberg Bank achieved case closure without an adverse finding, and no costs or fees were awarded against either party. However, because the dismissal is without prejudice, the bank cannot treat this as a final resolution of InnoMemory’s patent claims. If no confidential settlement was reached, Kleberg Bank should assess whether its use of the memory-related technology at issue remains a potential exposure point for a future action by InnoMemory or a related entity.
No fee award; exposure persistsShort-cycle patent filings against financial institutions: a pattern to monitor
Cases asserting hardware or memory architecture patents against financial sector defendants — which typically use commercial off-the-shelf technology — often reflect licensing campaign strategies. A 45-day lifecycle before voluntary dismissal is consistent with pre-answer settlement negotiations or a reassessment of claim mapping. Banks and financial institutions operating infrastructure relying on memory-intensive systems should monitor US7057960B1 and track whether InnoMemory pursues similar actions against comparable defendants.

Official order — verbatim text
The court’s order tracks the precise language of Rule 41(a)(1)(A)(i), confirming that InnoMemory acted before Kleberg Bank filed an answer, making the dismissal effective as of right without judicial discretion. The ‘without prejudice’ designation is legally significant: it means no claim preclusion attaches, US7057960B1 survives fully enforceable, and InnoMemory may refile. The order makes no finding on infringement, validity, or damages — the merits of the patent dispute remain entirely open.
US7057960B1 — Memory Device Refresh Power Reduction Architecture
US7057960B1 (application number US10/629667) claims a method and architectural framework for reducing the power consumed by memory devices during refresh cycles — an operation required to maintain data integrity in dynamic memory such as DRAM. Power efficiency in refresh operations is a commercially significant design challenge in embedded systems, mobile devices, and large-scale server infrastructure. The patent’s grant as a utility patent with a B1 designation indicates it issued without post-issuance amendment, suggesting the claims emerged from prosecution in their originally filed form.
For the semiconductor and memory systems sector, US7057960B1 represents potential coverage over a low-level architectural optimisation that is broadly applicable across product categories — from consumer DRAM to enterprise storage controllers. Its assertion against a financial institution, rather than a memory manufacturer or OEM, suggests the patent holder may be targeting downstream end-users of memory technology rather than its direct producers. This strategy, if pursued systematically, could implicate any organisation operating memory-intensive IT infrastructure procured from third-party vendors.
Should your product team run an FTO against US7057960B1?
Any organisation deploying memory systems that implement power-optimised refresh architectures — including server OEMs, embedded systems vendors, cloud infrastructure providers, and even large enterprises relying on commercial DRAM-based hardware — should assess their exposure to US7057960B1. The fact that InnoMemory targeted a regional bank, rather than a chip manufacturer, signals a willingness to pursue end-user defendants. If your product or infrastructure stack incorporates dynamic memory refresh optimisation at any level, an FTO review is warranted.
PatSnap Eureka’s FTO Search Agent can map the claims of US7057960B1 against your specific product architecture, identify overlapping prior art that may bear on validity, and surface any related continuation or family patents that could extend the assertion landscape. Eureka also monitors new filings by associated entities, so your team receives early warning if InnoMemory or Rabicoff Law initiates parallel actions in this technology domain.

What this case signals for the memory patent and financial sector IP landscape
A 45-day voluntary dismissal without prejudice rarely closes the book on a patent assertion campaign. Here is what IP teams should take away.
Without-prejudice dismissals preserve plaintiff optionality — monitor for refiling
InnoMemory’s withdrawal under Rule 41(a)(1)(A)(i) leaves US7057960B1 fully intact and enforceable. Financial institutions and technology vendors in the memory systems space should place this patent on watch and track any new filings by InnoMemory or associated entities. A rapid dismissal before answer is a common feature of licensing-driven litigation cycles.
Banks are non-obvious targets for memory architecture patents — audit your stack
Kleberg Bank’s position as a defendant in a memory refresh power-reduction patent suit highlights how financial institutions can face hardware-layer patent risk through the commercial IT infrastructure they procure. In-house IP teams at banks should consider whether their technology supply chain creates indirect exposure to patent claims that nominally target semiconductor or embedded systems technology.
InnoMemory v Kleberg — key questions answered
It means InnoMemory chose to end the case before Kleberg Bank filed an answer, using Rule 41(a)(1)(A)(i). No court ruled on the merits. The ‘without prejudice’ designation means InnoMemory retains the right to refile the same patent claims against Kleberg Bank in a future action, subject to applicable limitations periods.
US7057960B1 covers a method and architecture for reducing power consumption in memory devices during refresh operations — a hardware-layer technology typically associated with DRAM and embedded systems. Its assertion against Kleberg Bank, a financial institution, suggests an end-user targeting strategy, where the patent is applied to commercial IT infrastructure rather than to the memory hardware’s original manufacturer.
Yes. Because the dismissal was entered without prejudice, no claim preclusion applies. InnoMemory may refile an action asserting US7057960B1 against Kleberg Bank provided the applicable statute of limitations — generally six years for patent infringement under 35 U.S.C. § 286 — has not expired for the relevant acts of infringement.
The 45-day duration is consistent with InnoMemory filing the voluntary dismissal before Kleberg Bank served an answer, which is the procedural window for a Rule 41(a)(1)(A)(i) dismissal as of right. This rapid resolution may reflect a private settlement, a strategic reassessment of claim mapping against a banking defendant, or early resolution of a licensing demand. The public record does not disclose which of these occurred.
Financial institutions increasingly face patent assertions targeting the commercial IT infrastructure they procure, including memory-intensive server and storage systems. Patents covering memory refresh, power management, or DRAM architecture can be asserted against end-users if the hardware deployed is alleged to practise the claimed method. Banks should conduct periodic FTO reviews of their core infrastructure technology and monitor assertion activity by patent holders in the semiconductor and memory systems domain.
