InnoMemory v. Rio Bank: Patent Infringement Action Dismissed With Prejudice in 78 Days
InnoMemory, LLC brought a patent infringement action against Rio Bank in the Western District of Texas, asserting US7057960B1, which covers methods for reducing power consumption in memory device refresh operations. The case closed in just 78 days after InnoMemory filed a voluntary dismissal with prejudice under FRCP 41(a)(1)(A)(i), before Rio Bank had served any answer or dispositive motion.
Pre-Answer Dismissal With Prejudice Ends Memory Patent Suit Against Rio Bank
On February 3, 2025, InnoMemory, LLC filed a patent infringement complaint against Rio Bank in the U.S. District Court for the Western District of Texas (Case No. 7:25-cv-00046), asserting US7057960B1. The patent, filed under application number US10/629667, covers a method and architecture for reducing power consumption in memory devices during refresh operations — a technology area relevant to hardware-level memory management.
On April 21, 2025, InnoMemory filed a Notice of Voluntary Dismissal With Prejudice, invoking FRCP 41(a)(1)(A)(i). Because Rio Bank had not yet served an answer or motion for summary judgment, the notice was self-effectuating — the case terminated automatically without requiring a court order. The dismissal with prejudice means InnoMemory is permanently barred from bringing the same claims against Rio Bank on this patent. Each party was ordered to bear its own costs, expenses, and attorney fees.
The 78-day lifecycle — from filing to closure — is notably compressed, suggesting the dispute was resolved or abandoned before any substantive litigation commenced. No court filings indicate that claim construction, discovery, or dispositive motions were reached. The public record does not disclose whether a confidential settlement preceded the dismissal, or whether InnoMemory simply elected not to pursue the action further; the with-prejudice designation, however, forecloses any future re-filing of these specific claims against Rio Bank.

Dismissed with prejudice: what the voluntary exit means for both parties
FRCP 41(a)(1)(A)(i): self-effectuating dismissal before answer
Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action unilaterally — without a court order — by filing a notice before the defendant serves an answer or motion for summary judgment. Because Rio Bank had not yet responded, InnoMemory’s notice was immediately operative. The court’s order simply confirmed the procedural posture; it did not itself terminate the case. The with-prejudice designation was chosen by the plaintiff, not imposed by the court.
FRCP 41(a)(1)(A)(i)With prejudice: this door is permanently closed against Rio Bank
A dismissal with prejudice operates as a final adjudication on the merits, barring InnoMemory from ever re-filing the same patent claims against Rio Bank. This is a materially stronger concession than a dismissal without prejudice, which would preserve the right to re-file. The public record does not disclose what — if anything — prompted InnoMemory to accept this permanent bar, though it is consistent with a negotiated resolution or a strategic decision not to proceed.
Permanent claim barRio Bank exits without admitting infringement or paying adjudicated damages
Rio Bank achieved closure without serving a single substantive filing. No answer, no invalidity counterclaims, and no motion for summary judgment appear on the docket. The with-prejudice dismissal provides Rio Bank with a res judicata shield against InnoMemory’s US7057960B1 claims — a commercially clean outcome. Each party bearing its own costs also means Rio Bank incurred no fee-shifting liability, though its own legal costs through counsel at Kelly Hart & Hallman LLP remain undisclosed.
Defendant protectedUS7057960B1 remains live — other defendants are unaffected by this dismissal
The with-prejudice dismissal is specific to Rio Bank. US7057960B1 remains an issued, enforceable U.S. patent and could be asserted against other parties. Companies whose products or platforms incorporate memory architectures addressing refresh-cycle power consumption should note that this resolution does not neutralise the patent’s enforcement potential. The patent’s application date context and continued validity suggest ongoing FTO risk for hardware and embedded-systems vendors.

Official order — verbatim text
The court’s order confirms that InnoMemory’s Notice of Voluntary Dismissal With Prejudice was self-effectuating under FRCP 41(a)(1)(A)(i) — no judicial action was required to terminate the case. The with-prejudice designation is legally significant: it constitutes a final adjudication on the merits for purposes of claim preclusion, permanently barring InnoMemory from re-asserting US7057960B1 against Rio Bank. The fee-neutrality order — each party bearing its own costs — is standard for voluntary dismissals at this stage and does not reflect any finding on the merits of the infringement allegations.
US7057960B1 — Memory Device Power Reduction in Refresh Operations
US7057960B1 (application no. US10/629667) covers a method and architecture directed at reducing power consumption in memory devices specifically during refresh operations. Refresh cycles — the periodic process by which DRAM and similar volatile memory technologies recharge stored data — are a known source of power overhead in memory-intensive systems. A patent addressing architectural approaches to minimising this overhead sits at the intersection of hardware design and energy efficiency, areas of sustained commercial importance in embedded systems, mobile computing, and data-centre memory management.
From a strategic standpoint, a patent covering memory refresh power reduction has broad potential applicability across any product category relying on DRAM or similar volatile memory — from banking infrastructure and fintech hardware platforms to consumer electronics and industrial embedded systems. The assertion of this patent against a regional bank suggests InnoMemory may be targeting technology deployed in financial services infrastructure, though the specific accused products were not detailed in the public docket. The patent’s enforceability was not tested in this case, making competitor risk assessment dependent on independent claim analysis.
Should your team run an FTO against US7057960B1?
Any R&D team or product organisation working with memory architectures that include refresh-cycle optimisation or power-reduction techniques should treat US7057960B1 as a relevant FTO target. This applies to hardware vendors, DRAM controller designers, SoC developers, and platform teams in fintech or enterprise infrastructure whose products rely on memory refresh management. The patent was asserted in active litigation as recently as early 2025, confirming it is being actively monitored and enforced by its holder.

What this case signals for the memory technology IP landscape
A swift with-prejudice exit in W.D. Texas often signals more than a simple withdrawal — here is what practitioners should read into it.
Pre-answer dismissals with prejudice frequently signal a negotiated exit
When a plaintiff voluntarily dismisses with prejudice before the defendant has even answered, it typically suggests either a private settlement or a strategic reassessment. The with-prejudice designation — a stronger concession than required — is consistent with an agreed resolution, though the public record is silent on terms. IP professionals should treat this pattern as a potential indicator of licensing activity.
US7057960B1 is unresolved as to validity — FTO risk persists for the sector
No invalidity ruling, IPR, or claim construction was reached in this case. The patent survived this litigation entirely on procedural grounds. For any company whose products involve memory device refresh architectures, US7057960B1 remains a live enforcement risk. A targeted FTO analysis against this patent is warranted before product launch or design finalisation in the relevant hardware stack.
InnoMemory v Rio — key questions answered
The case was voluntarily dismissed with prejudice by InnoMemory on April 21, 2025, under FRCP 41(a)(1)(A)(i), before Rio Bank served an answer or any dispositive motion. The dismissal was self-effectuating and constitutes a permanent bar on InnoMemory re-filing the same claims against Rio Bank. Each party bore its own costs.
The dismissal with prejudice applies only to InnoMemory’s claims against Rio Bank. US7057960B1 remains an issued, enforceable U.S. patent. InnoMemory retains the right to assert it against other defendants. No validity or claim construction ruling was made, so the patent’s legal scope is unchanged by this dismissal.
US7057960B1 (application no. US10/629667) is a U.S. patent covering a method and architecture for reducing power consumption in memory devices during refresh operations. It is relevant to hardware designers and developers working with volatile memory technologies such as DRAM, where refresh cycles represent a measurable power overhead.
The public record does not disclose InnoMemory’s reasons. Filing a voluntary dismissal under FRCP 41(a)(1)(A)(i) before the defendant answers is procedurally straightforward and requires no court approval. The with-prejudice designation — stronger than required — is consistent with either a negotiated resolution or a strategic decision not to pursue the litigation, though neither is confirmed by the docket.
No. The dismissal does not extinguish or limit US7057960B1’s enforceability against third parties. Because no invalidity finding, IPR, or claim construction was issued, the patent’s scope and validity remain untested. Companies in the memory architecture and hardware sectors should treat this patent as a live FTO concern and conduct independent claim analysis before deploying relevant technology.
