InnoMemory v. TP-Link: Memory Patent Dismissed With Prejudice in 94 Days
InnoMemory, LLC asserted US7057960B1 — a patent covering power-reduction architecture for memory device refresh operations — against TP-Link Technology Co., Ltd. in the Eastern District of Texas. The plaintiff voluntarily dismissed the case with prejudice just 94 days after filing, permanently foreclosing refiling of the same claims.
A swift, permanent exit: InnoMemory drops TP-Link memory patent suit
On 19 August 2024, InnoMemory, LLC filed Case No. 2:24-cv-00683 in the Eastern District of Texas, asserting infringement of US7057960B1 against TP-Link Technology Co., Ltd. The patent in suit covers a method and architecture for reducing power consumption in memory devices during refresh operations — a foundational concern in DRAM and embedded memory design. InnoMemory was represented by Rabicoff Law LLC, a firm with a notable volume practice in E.D. Texas patent assertions.
The case closed on 21 November 2024, just 94 days after filing, when InnoMemory filed a Notice of Voluntary Dismissal with prejudice under Rule 41(a)(1)(A)(i). The court accepted and acknowledged the notice, dismissing all pending claims with prejudice and denying all other relief as moot. Critically, each party was ordered to bear its own costs, attorneys’ fees, and expenses — indicating no fee-shifting agreement was memorialised in the record.
A dismissal with prejudice at this early stage — before any defendant response or substantive motion practice appears on the docket — typically signals a private resolution, a licensing agreement, or a strategic recalculation by the plaintiff. The public record is silent on whether any consideration changed hands. The with-prejudice designation is significant: InnoMemory is permanently barred from asserting the same claims of US7057960B1 against TP-Link, raising questions about the patent’s enforceability and commercial value going forward.
Filing to Voluntary dismissal in 94 days
94 days — well under the E.D. Texas median; suggests pre-trial resolution
Dismissed with prejudice: what this outcome means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss — but at a cost
Under Rule 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss before the defendant serves an answer or a motion for summary judgment. Filing with prejudice, however, is an irrevocable waiver — the plaintiff surrenders the right to re-litigate the same claims against this defendant. The court accepted the notice without requiring TP-Link’s consent, consistent with the rule’s pre-answer timing.
Permanent claim barInnoMemory permanently forfeits its infringement claims against TP-Link
By dismissing with prejudice, InnoMemory extinguished its ability to reassert US7057960B1 against TP-Link in any future proceeding. If this was a strategic settlement, the terms are not public. If it reflects a weakness in the claim, the with-prejudice designation compounds that exposure — and may signal vulnerability to other defendants or potential IPR petitioners watching the docket.
No re-filing permittedTP-Link exits without a merits ruling — but no fee award either
TP-Link avoids any adjudication on infringement or validity, which offers a clean exit but no declaratory judgment protecting it. The own-costs order means TP-Link cannot recover its defence expenditures. Future assertion of US7057960B1 by InnoMemory against TP-Link is permanently barred, but the patent remains live against other parties unless challenged or expired.
Clean exit, no recoveryUS7057960B1 survives — but its enforcement posture is now weakened
The swift with-prejudice dismissal against a major networking OEM may signal licensing friction or claim-scope concerns in the memory refresh power domain. Other defendants in related assertions — or prospective licensees — may take note of InnoMemory’s inability to sustain this action. Companies designing or selling products with DRAM or embedded memory refresh architectures should monitor the patent’s remaining claim scope and any related continuations.

Official order — verbatim text
The court’s order accepts the plaintiff’s Rule 41(a)(1)(A)(i) notice without substantive analysis — the with-prejudice designation was plaintiff’s own choice, not imposed by the court. The absence of any finding on infringement or validity means TP-Link holds no declaratory judgment shield, while InnoMemory is permanently barred from reasserting these claims against this defendant. The moot denial of all other relief and the own-costs order are procedurally routine at this stage.
US7057960B1 — Memory device power reduction in refresh operations
US7057960B1, filed under application number US10/629667, protects a method and architecture for reducing power consumption in memory devices during refresh operations — a process essential to DRAM and certain embedded memory architectures where periodic refresh cycles consume significant energy. The patent addresses a known bottleneck in memory system design: the power overhead imposed by mandatory refresh cycles that maintain data integrity in volatile memory.
Power-efficient memory refresh is commercially significant across consumer electronics, networking equipment, mobile platforms, and data centre hardware. TP-Link’s product portfolio — spanning routers, switches, and smart home devices — incorporates memory subsystems where this architecture could theoretically apply. The assertion against a high-volume networking OEM suggests InnoMemory identified a broad potential licensing base, though the swift withdrawal may indicate claim-scope limitations or prior art exposure that undermines broad enforcement.
Should your product team run an FTO against US7057960B1?
Any R&D or product team working on devices incorporating DRAM, LPDDR, or embedded memory with refresh-cycle management should treat US7057960B1 as a live FTO item. The patent’s focus on power-reduction architecture during refresh operations is broadly applicable to networking hardware, IoT devices, mobile SoCs, and edge computing modules — all sectors with increasing memory efficiency demands.

A with-prejudice walk-away against a well-resourced OEM in E.D. Texas carries strategic weight beyond the docket.
Early dismissal with prejudice is a red flag for patent enforcement viability
When a plaintiff files with prejudice before the defendant even enters an appearance, it typically suggests either a private deal was struck or the plaintiff assessed significant risk — claim construction, prior art, or eligibility concerns. Either scenario is worth tracking if US7057960B1 appears in your technology landscape.
No fee award leaves TP-Link’s defence costs unrecovered
The own-costs order is standard in voluntary dismissals absent a consent judgment. TP-Link received no § 285 exceptional case fee award, which is consistent with the pre-answer timing — courts rarely find exceptional case status without substantive motion practice. Defendants in similar early-stage assertions should note this ceiling on cost recovery.
InnoMemory v TP-Link — key questions answered
A dismissal with prejudice under Rule 41(a)(1)(A)(i) permanently bars InnoMemory from reasserting the same claims of US7057960B1 against TP-Link. The court accepted InnoMemory’s own notice — it was not forced by the court — meaning InnoMemory elected this outcome. No finding on infringement or validity was made.
No. The with-prejudice designation is an absolute bar against refiling the same claims against TP-Link. InnoMemory could potentially assert different claims or related patents, but the specific claims dismissed in Case No. 2:24-cv-00683 cannot be relitigated against TP-Link in any forum.
The public record does not disclose a reason. Common explanations for a pre-answer voluntary dismissal with prejudice include: a confidential settlement or licence agreement; a reassessment of claim strength following pre-suit due diligence gaps; or a strategic decision to avoid costly Markman or invalidity proceedings. The own-costs order does not confirm or deny a monetary settlement.
US7057960B1 covers a method and architecture for reducing power consumption in memory devices during refresh operations — relevant to DRAM and embedded memory used in networking and consumer electronics hardware. TP-Link’s broad product portfolio of routers and smart devices incorporating memory subsystems likely made it a target for this assertion.
No. A voluntary dismissal with prejudice carries no finding on validity or infringement. US7057960B1 remains a granted patent unless challenged via inter partes review, ex parte reexamination, or found invalid in a separate proceeding. Other potential defendants cannot rely on this dismissal as prior adjudication on the patent’s merits.
