A patent infringement lawsuit targeting DDR memory technology in banking infrastructure ended not with a trial verdict, but with a mutual walk-away. In InnoMemory, LLC v. Broadway National Bank (Case No. 5:22-cv-00905), filed in the Western District of Texas, both parties agreed to dismiss all claims and counterclaims with prejudice — each bearing its own legal costs. The case, which ran for 705 days before closing on July 22, 2024, centered on two U.S. patents covering memory technology allegedly infringed through DDR memory systems deployed across Broadway National Bank’s computing infrastructure, including automated teller machines.

For patent attorneys tracking NPE (non-practicing entity) assertion strategies, IP professionals monitoring financial sector patent exposure, and R&D teams managing freedom-to-operate (FTO) risks in memory technology, this case offers a revealing window into how DDR memory patent litigation is being pursued — and resolved — outside of courtroom adjudication. The stipulated dismissal reflects strategic calculus on both sides that warrants careful analysis.

Case Overview

The Parties

The Patents at Issue

Two U.S. patents formed the foundation of InnoMemory’s infringement claims, both covering computing memory system architecture and relevant to DDR memory standards.

• • U.S. Patent No. 7,057,960 B1 — Covers memory technology relevant to DDR memory system architecture.
• • U.S. Patent No. 6,240,046 B1 — An earlier patent in the memory technology space, suggesting a portfolio with temporal depth across DDR generations.

The Verdict & Legal Analysis

Outcome

The case was **dismissed with prejudice** pursuant to a **Joint Stipulation of Dismissal** under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All of InnoMemory’s infringement claims and all of Broadway National Bank’s counterclaims were terminated. Critically, **each party agreed to bear its own costs, expenses, and attorneys’ fees** — a mutual cost-neutrality arrangement that forecloses any future re-filing of the same claims.

No damages were awarded. No injunctive relief was granted. No disclosed settlement amount is part of the public record.

Verdict Cause Analysis

The dismissal with prejudice — without disclosed monetary consideration — invites several strategic interpretations:

Confidential Settlement: The most commercially common explanation is an undisclosed licensing agreement or lump-sum payment negotiated privately before dismissal. The “each party bears its own costs” language is frequently used in settlements where the defendant pays an undisclosed sum, allowing both sides to avoid fee-shifting arguments.

Defendant’s Resistance: Broadway National Bank, as an end-user institution rather than a memory manufacturer, likely had strong incentives to contest the assertion on both infringement and damages grounds. End-user defendants often present unfavorable damages profiles for plaintiffs, as royalty calculations tied to banking operations rather than memory product revenues can be complex and modest.

Portfolio Risk Assessment: InnoMemory may have weighed the litigation cost against the anticipated licensing value from a single regional bank defendant — particularly with no manufacturer co-defendant sharing defense costs or contributing to invalidity challenges.

Legal Significance

This case does not produce a precedential ruling on claim construction, patent validity, or infringement of the asserted patents. The dismissal with prejudice under Rule 41(a)(1)(A)(ii) is self-executing upon filing — as the court noted, citing Yesh Music v. Lakewood Church, 727 F.3d 356, 362 (5th Cir. 2013) — requiring no judicial merits determination.

However, the case contributes to the evidentiary landscape of **end-user DDR memory patent litigation**, demonstrating that assertion strategies targeting financial institutions for DDR memory usage face natural commercial and litigation pressure points.
