Case Overview
The Parties
⚖️ Plaintiff
A patent holding entity asserting rights over memory-related semiconductor technologies, consistent with non-practicing entities (NPEs) active in technology-adjacent industries.
🛡️ Defendant
A major U.S. financial services company operating across retail and commercial banking, deploying integrated circuit memory systems across its IT infrastructure.
The Patents at Issue
This case involved two U.S. patents covering integrated circuit memory architecture and power-saving refresh methods, addressing foundational aspects of memory device functionality. Both patents are registered with the U.S. Patent and Trademark Office (USPTO).
- • U.S. Patent No. 7,057,960 B1 — Covers an integrated circuit random access memory capable of reading either one or more than one data word in a single clock cycle.
- • U.S. Patent No. 6,240,046 B1 — Covers a method and architecture for reducing power consumption in memory devices during refresh operations.

The Verdict & Legal Analysis
Outcome
On April 15, 2024, InnoMemory filed a notice of voluntary dismissal with prejudice, terminating all claims against Regions Financial. The court closed the case the following day, April 16, 2024, without issuing any substantive ruling on the merits or awarding any damages.
Key Legal Issues
The dismissal was effectuated pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss an action without a court order *before* the opposing party serves either an answer or a motion for summary judgment. This “self-effectuating” rule means no court order was required for termination. The critical distinction is the dismissal “with prejudice,” which permanently bars InnoMemory from reasserting the same claims against Regions Financial for these specific patents.

Defense Strategy
Early, credible defense can resolve quickly
✅ Key Takeaways
Rule 41(a)(1)(A)(i) dismissals with prejudice permanently bar reassertion — a material consequence plaintiffs must weigh.

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 (memory refresh power reduction method), both asserted against Regions Financial Corporation.
InnoMemory filed a voluntary notice of dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i) before Regions Financial served an answer or summary judgment motion. No public explanation was provided; a confidential settlement is one plausible explanation.
It reinforces that early, credible defense engagement can resolve NPE assertions quickly — and that plaintiffs must carefully consider the permanent consequences of with-prejudice voluntary dismissals.
