InnoMemory v. First National Bank of Bastrop: Patent Suit Ends in 79 Days
InnoMemory, LLC filed a patent infringement action in the Western District of Texas asserting US7057960B1 — a patent covering power-reduction architectures for memory device refresh operations — against First National Bank of Bastrop. The case closed in just 79 days when InnoMemory voluntarily dismissed its claims with prejudice before the defendant filed any answer or dispositive motion.
A pre-answer exit: InnoMemory drops memory patent suit with finality
On February 2, 2025, InnoMemory, LLC filed suit against First National Bank of Bastrop in the Western District of Texas (Case No. 7:25-cv-00043), asserting infringement of US7057960B1. The patent covers a method and architecture for reducing power consumption in memory devices during refresh operations — a technical area associated with embedded or enterprise memory systems rather than traditional financial services products, making the choice of defendant commercially notable.
The action ended on April 22, 2025, when the court acknowledged InnoMemory’s Notice of Voluntary Dismissal With Prejudice filed the previous day. InnoMemory invoked FRCP 41(a)(1)(A)(i), which permits a plaintiff to unilaterally dismiss before the opposing party serves an answer or summary judgment motion. Because First National Bank of Bastrop had not yet done either, the dismissal was self-effectuating and required no court order to take legal effect. The with-prejudice designation extinguishes InnoMemory’s right to refile these specific claims against this defendant.
A 79-day lifecycle — ending before any substantive defendant pleading — is consistent with pre-litigation resolution dynamics: the parties may have reached a private agreement, or InnoMemory may have determined the litigation was not viable once defendant counsel engaged. The public record is silent on any settlement terms. Each party bearing its own costs suggests no financial concession was extracted, though private licensing arrangements, if any, would not appear on the docket.

Dismissed with prejudice: what the voluntary exit means for both parties
FRCP 41(a)(1)(A)(i): plaintiff’s right to exit before answer
Rule 41(a)(1)(A)(i) grants a plaintiff the unilateral right to dismiss an action without a court order, provided the defendant has not yet served an answer or motion for summary judgment. Here, First National Bank of Bastrop had taken neither step, so InnoMemory’s notice was self-effectuating under Fifth Circuit precedent (In re Amerijet Int’l). No judicial approval was required; the filing itself terminated the case.
Self-effectuating dismissalWith prejudice: InnoMemory permanently barred from refiling these claims
A voluntary dismissal with prejudice operates as a final adjudication on the merits under res judicata principles. InnoMemory has permanently relinquished its right to sue First National Bank of Bastrop again on the same claims under US7057960B1. This contrasts with a without-prejudice dismissal, which would preserve the right to refile. The public record does not indicate why InnoMemory chose the more final with-prejudice form — a private settlement or licensing agreement may have been the underlying driver.
Res judicata bar appliesBank exits without any admission or pleading on record
First National Bank of Bastrop never filed an answer, counterclaim, or dispositive motion. The defendant emerges from this action with a clean docket record — no finding of infringement, no invalidity ruling on US7057960B1, and no cost award against it. Each party bearing its own fees means the bank absorbed its own legal costs for the 79-day period. It is permanently protected from this specific plaintiff on these specific claims.
No liability findingUS7057960B1 survives — validity untested by this action
Because the case resolved before any substantive merits engagement, the validity, enforceability, and scope of US7057960B1 were never adjudicated. The patent’s claims remain open to future assertion against other defendants. Any entity operating memory systems that may implicate this patent’s refresh-power claims should note that no claim construction or invalidity analysis exists in this case’s record to rely upon as prior art or estoppel.

Official order — verbatim text
The court’s order confirms InnoMemory’s dismissal was procedurally valid under FRCP 41(a)(1)(A)(i): because First National Bank of Bastrop had not served an answer or summary judgment motion, no judicial action was needed to effectuate termination. The with-prejudice designation is particularly significant — it reflects InnoMemory’s voluntary choice to extinguish its own claims permanently, likely suggesting a private resolution rather than a strategic withdrawal for refiling.
US7057960B1 — Memory Device Refresh Power-Reduction Method and Architecture
US7057960B1 (application no. US10/629667) claims a method and architecture directed at reducing power consumption in memory devices specifically during refresh operations — a critical aspect of DRAM and related memory technology management. Refresh operations require periodic recharging of memory cells and represent a meaningful power draw, particularly in embedded, mobile, or high-density memory environments. The patent’s focus on architectural solutions suggests claims that may extend beyond a single implementation to cover broader system-level approaches to power management in refresh cycles.
For the memory semiconductor and systems sector, this patent’s continued validity without any judicial narrowing means claim scope remains as broad as the patent office granted. Companies building or licensing DRAM controllers, embedded memory subsystems, or power-management firmware for memory devices should treat US7057960B1 as an active risk vector. The assertion against a bank — an unlikely direct manufacturer — may suggest the patent holder is targeting technology users rather than developers, broadening the pool of potentially exposed entities.
Should you run an FTO analysis against US7057960B1?
Any R&D team or product group developing memory controllers, SoC architectures, or firmware that governs DRAM refresh cycles should assess exposure to US7057960B1. The patent’s claims around power-reduction methods during refresh operations could implicate a broad range of products — from enterprise server memory to embedded IoT memory subsystems. Financial institutions and enterprise technology buyers deploying memory-intensive infrastructure are also potentially within scope based on this case’s assertion pattern.

What this case signals for the memory technology patent assertion landscape
A pre-answer dismissal with prejudice in a W.D. Tex. patent suit raises questions about assertion strategy and private resolution dynamics.
Pre-answer dismissals may conceal private licensing activity
When a plaintiff voluntarily dismisses with prejudice before the defendant files any pleading, the most commercially plausible explanation is a private settlement or licensing agreement. The public record here is silent on terms. IP teams monitoring InnoMemory’s portfolio activity should track subsequent licensing disclosures or further filings against similar defendants.
US7057960B1 validity remains untested — assertion risk persists for memory sector
No claim construction, invalidity argument, or IPR record was generated by this action. For companies developing or deploying memory architectures that involve refresh-cycle power management, US7057960B1 remains a live assertion risk. An FTO analysis against this patent is advisable given the absence of any judicial narrowing of its claims.
InnoMemory v First — key questions answered
InnoMemory, LLC filed a patent infringement suit against First National Bank of Bastrop in the Western District of Texas on February 2, 2025, asserting US7057960B1. The case was voluntarily dismissed with prejudice by InnoMemory on April 21, 2025, before the defendant filed any answer or dispositive motion. The court acknowledged the self-effectuating dismissal on April 22, 2025. Each party bore its own costs.
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. When filed with prejudice, the dismissal permanently bars the plaintiff from refiling the same claims against the same defendant — it operates as a final judgment on the merits. Without prejudice would preserve the right to refile; with prejudice does not.
US7057960B1 is a US patent (application no. US10/629667) that claims a method and architecture for reducing power consumption in memory devices during refresh operations. It is directed at DRAM and related memory technology where refresh cycles — periodic recharging of memory cells — represent a significant power draw. The patent has not been subjected to claim construction or IPR review in this case, leaving its full scope judicially untested.
No. Because InnoMemory chose to dismiss with prejudice, res judicata principles bar it from reasserting the same patent claims under US7057960B1 against First National Bank of Bastrop in any future action. The with-prejudice designation was InnoMemory’s own election and was not compelled by the court, suggesting the parties may have reached a private resolution prior to the filing.
No. The dismissal resolved only InnoMemory’s claims against First National Bank of Bastrop. No invalidity ruling, claim construction order, or IPR institution decision was generated. US7057960B1 remains fully enforceable against other parties, and its claim scope is as broad as granted. Companies in the memory semiconductor, embedded systems, or enterprise infrastructure sectors should treat the patent as an active assertion risk.
