InnoMemory v. JPMorgan Chase: Memory Patent Dispute Ends in Dismissal

A patent infringement action targeting one of the world’s largest financial institutions has concluded quietly — but strategically. In InnoMemory, LLC v. JPMorgan Chase Bank, N.A. (Case No. 2:24-cv-00151), the Eastern District of Texas issued a dismissal with prejudice on April 23, 2025, following a joint motion by both parties confirming the dispute had been privately resolved. The case, which centered on two U.S. patents covering integrated circuit memory technology, lasted approximately 418 days from filing to closure.

For patent attorneys, IP professionals, and R&D leaders operating in the semiconductor and memory technology space, this case reflects a recognizable pattern: NPE-driven patent assertion in a plaintiff-friendly venue, followed by a confidential resolution before trial. While the settlement terms remain undisclosed, the litigation arc — from filing in Marshall, Texas, to joint dismissal — offers meaningful lessons about assertion strategy, defensive posturing, and the ongoing commercialization of legacy memory patents against technology-dependent enterprises.

Case Overview

The Parties

Patents at Issue

Two U.S. patents formed the foundation of InnoMemory’s infringement claims, covering foundational memory performance and energy efficiency concepts:

• • U.S. Patent No. 7,057,960 B1 — Integrated circuit RAM architecture for multi-word reads per clock cycle.
• • U.S. Patent No. 6,240,046 B1 — Method and architecture to reduce power consumption in memory devices during refresh operations.

Litigation Timeline & Procedural History

InnoMemory filed suit on March 1, 2024, in the U.S. District Court for the Eastern District of Texas — a venue long favored by patent plaintiffs for its historically plaintiff-friendly docket management and experienced patent litigation bench. The case was designated as a first-instance district court matter.

The 418-day duration — just under 14 months — is consistent with pre-trial resolution timelines in Eastern District NPE cases, where defendants frequently engage in parallel IPR (Inter Partes Review) proceedings at the USPTO, aggressive early motion practice, or direct settlement negotiations to avoid full trial exposure. No trial was held.

The case was resolved through a Joint Motion to Dismiss (Docket No. 82), with both parties representing to the court that the matter had been privately resolved. No publicly disclosed damages figure, licensing terms, or injunctive relief order exists in the record.

The Verdict & Legal Analysis

Outcome

On April 23, 2025, the Eastern District of Texas granted the parties’ Joint Motion to Dismiss, ordering that all claims and causes of action between InnoMemory, LLC and JPMorgan Chase Bank, N.A. are DISMISSED WITH PREJUDICE. Each party was ordered to bear its own costs, expenses, and attorneys’ fees. All pending requests for relief were denied as moot.

The dismissal with prejudice — as opposed to without prejudice — confirms this was a final, negotiated resolution, not an abandonment. InnoMemory cannot re-file identical claims on these patents against JPMorgan Chase in a future action.

No damages amount was publicly disclosed. Settlement terms, if any, remain confidential.

Verdict Cause Analysis

The case was initiated as a straightforward patent infringement action. The joint dismissal, while procedurally unremarkable, carries strategic weight:

• JPMorgan Chase’s defense deployment of four law firms signals an early, aggressive defensive strategy designed to increase litigation costs and signal credible trial readiness — a common tactic against NPE plaintiffs who face asymmetric cost pressure.
• InnoMemory’s decision to resolve pre-trial is consistent with NPE economics: licensing revenue secured without trial risk represents a successful assertion outcome, even if terms remain private.
• The absence of any reported claim construction ruling, summary judgment decision, or Markman hearing order on the public docket suggests resolution occurred in the relatively early-to-mid litigation phase.

Legal Significance

While this case produced no published legal opinion, its significance lies in what it reflects about NPE assertion strategy targeting financial sector defendants using foundational semiconductor patents. Financial institutions like JPMorgan Chase are increasingly named defendants in memory and computing patent cases because their infrastructure operations implicate the same technology claims originally directed at hardware manufacturers.

The patents-in-suit — both issued in the early 2000s — represent mature, pre-litigation-reform-era IP assets being actively monetized. Their claims on multi-word RAM read cycles (U.S. 7,057,960) and low-power refresh architectures (U.S. 6,240,046) touch technologies embedded throughout enterprise computing stacks, creating broad assertion surface area.

Strategic Takeaways

For Patent Holders & Asserting Entities:

Financial sector defendants with deep pockets and reputational stakes often resolve NPE assertions to avoid prolonged discovery and litigation distraction, even when defenses are available. Selecting Eastern District of Texas remains a viable venue strategy for NPE plaintiffs targeting infrastructure-dependent enterprises.

For Accused Infringers:

Deploying multi-firm defense teams signals credible trial readiness and may accelerate resolution on favorable terms. Consider parallel USPTO proceedings (IPR/PGR) as cost-effective leverage tools, particularly against older patents with potential prior art exposure.

For R&D Teams:

Memory architecture patents from the early 2000s remain active litigation assets. Freedom-to-operate (FTO) analyses for products using legacy RAM architectures should account for NPE-held portfolios. Power-reduction memory techniques, particularly refresh optimization methods, are a recognized assertion category warranting proactive IP clearance.

Industry & Competitive Implications

This case is one data point in a larger trend: NPE entities asserting foundational semiconductor and memory patents against end-user enterprises rather than (or in addition to) chip manufacturers. Financial institutions, cloud providers, and enterprise software companies are increasingly exposed because their technology infrastructure relies on patented hardware innovations they did not design or manufacture.

For the memory technology sector broadly, the monetization of U.S. 7,057,960 and U.S. 6,240,046 signals that early-2000s RAM and refresh patents remain commercially viable assertion vehicles more than two decades after issuance. IP professionals tracking NPE activity in the semiconductor space should monitor InnoMemory’s broader patent portfolio and any related litigation filings.

The multi-defendant “member case” language in the court’s dismissal order — referencing an “above-captioned member case” — suggests JPMorgan Chase may have been one defendant among several in a coordinated multi-defendant assertion campaign, a standard NPE strategy to maximize licensing yield.

Companies evaluating exposure to similar claims should consider proactive patent landscape analyses covering multi-word memory access architectures and low-power DRAM refresh methodologies.

❓ Frequently Asked Questions

What patents were involved in InnoMemory v. JPMorgan Chase?
The case involved U.S. Patent No. 7,057,960 B1 (multi-word RAM read architecture) and U.S. Patent No. 6,240,046 B1 (low-power memory refresh method and architecture).

Why was the case dismissed with prejudice?
Both parties filed a joint motion representing the matter had been privately resolved. Dismissal with prejudice is a final resolution — InnoMemory cannot reassert these specific claims against JPMorgan Chase on these patents.

How does this case affect memory technology patent litigation?
It reinforces the pattern of NPE assertion of legacy semiconductor patents against enterprise-sector end users, with pre-trial resolution remaining the dominant outcome in Eastern District of Texas NPE cases.
