Intercurrency Software v. Nium: Voluntary Dismissal in Cross-Border Payment Patent Dispute

Introduction

A patent infringement lawsuit targeting one of fintech’s fastest-growing cross-border payment platforms has ended not with a courtroom battle, but with a quiet exit. Intercurrency Software LLC voluntarily dismissed its case against Nium Pte. Ltd. with prejudice on March 2, 2026 — a resolution that raises as many strategic questions as it answers.

Filed July 9, 2025, in the Eastern District of Texas before Chief Judge Rodney Gilstrap, the case centered on two U.S. patents covering apparatus and methods for consolidated trading and international payment platforms. Nium’s Instarem Personal and Business international payment platforms were identified as the accused products. The case closed after 236 days without a merits ruling, damages award, or injunctive relief.

For patent attorneys, in-house counsel, and fintech R&D teams, this dismissal-with-prejudice carries meaningful strategic signals — from prosecution posture to assertion risk in cross-border payment technology. Understanding what happened, and why it matters, requires unpacking the procedural record and the competitive landscape it reflects.

Case Overview

The Parties

Patents at Issue

Two issued U.S. patents formed the basis of the infringement claims, addressing integrated, multi-function financial transaction architectures:

• • U.S. Patent No. 10,062,107 B1 — Apparatus and methods for a consolidated trading platform
• • U.S. Patent No. 11,620,701 B1 — A continuation-family patent extending related claims into fintech payment processing

The Accused Products

Nium’s Instarem Personal and Business international payment platforms and systems were accused of infringing these patents. Instarem processes cross-border transactions across dozens of currency corridors, making it commercially significant and a high-profile target in cross-border payment patent litigation.

Legal Representation

Plaintiff: Christopher A. Honea of Garteiser Honea PLLC — a Tyler, Texas-based firm with extensive experience in patent assertion before Judge Gilstrap

Defendant: Christian Taylor Tatum, Kyle Soren Sorenson, and Syed Kamil Fareed of McDermott Will & Emery LLP and McDermott Will & Schulte LLP — global firms with deep IP litigation defense capabilities

Litigation Timeline & Procedural History

The Eastern District of Texas — and specifically Judge Gilstrap’s docket — remains among the most plaintiff-favorable patent venues in the United States, known for efficient case management, strong patent precedent, and high trial rates. Garteiser Honea PLLC’s selection of this venue was consistent with its established litigation pattern before Judge Gilstrap.

The case resolved at the first-instance district court level without reaching claim construction, summary judgment, or trial. The plaintiff filed a Notice of Voluntary Dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i) — a unilateral dismissal mechanism available before a defendant serves an answer or motion for summary judgment — or, in some circumstances, by court order thereafter.

The 236-day duration suggests the parties engaged in some pre-trial activity before Intercurrency opted to exit. No published claim construction order, inter partes review (IPR) petition, or summary judgment ruling appears in the available case record, meaning the strategic calculus behind the dismissal remains largely private.

The Verdict & Legal Analysis

Outcome

The case was dismissed with prejudice on March 2, 2026, pursuant to Intercurrency Software LLC’s voluntary Notice of Dismissal (Dkt. No. 54). Chief Judge Gilstrap accepted the notice and ordered each party to bear its own costs, expenses, and attorneys’ fees. All remaining claims were denied as moot.

No damages were awarded. No injunctive relief was granted or denied on the merits. The dismissal with prejudice means Intercurrency cannot refile the same claims against Nium on these patents — a legally significant endpoint.

Verdict Cause Analysis

The operative cause was a voluntary dismissal under Rule 41(a)(1)(A)(i), meaning Intercurrency initiated the exit without adjudication of the merits. Several strategic scenarios could explain this outcome:

Scenario 1 — Pre-litigation settlement or licensing agreement: The most common explanation for NPE voluntary dismissals with prejudice is a negotiated resolution. A licensing agreement reached privately would render continued litigation unnecessary, and dismissal with prejudice would confirm the matter fully resolved.

Scenario 2 — Patent validity concerns: If Nium’s defense team identified vulnerabilities in U.S. Patent Nos. 10,062,107 or 11,620,701 — whether through prior art searches, IPR threat, or claim construction challenges — Intercurrency may have strategically withdrawn to preserve licensing leverage in future assertions against other targets.

Scenario 3 — Adverse claim construction signals: Early Markman briefing or informal judicial guidance suggesting unfavorable claim interpretations could motivate a plaintiff to exit before a binding adverse ruling issued.

The fee-splitting order (each party bears its own costs) is neutral on its face, consistent with both a settlement scenario and a straightforward voluntary exit.

Legal Significance

Because the case dismissed without prejudice on the merits, it carries limited direct precedential value regarding the validity or scope of U.S. Patent Nos. 10,062,107 and 11,620,701. However, the dismissal with prejudice does establish that Intercurrency’s claims against Nium on these specific patents are permanently extinguished — a material fact for any future freedom-to-operate (FTO) analysis involving Nium’s Instarem platform.

Strategic Takeaways

For patent holders and assertion entities:

• Voluntary dismissal with prejudice forecloses reassertion against the same defendant — a significant concession that should only follow confirmed licensing revenue or a deliberate portfolio strategy decision
• NPE assertions in fintech are increasingly meeting well-resourced defense teams capable of mounting IPR petitions and prior art campaigns that fundamentally threaten patent viability

For accused infringers:

• Engaging experienced defense counsel (as Nium did with McDermott Will & Emery) early and aggressively can create conditions that motivate plaintiff withdrawal before costly trial proceedings
• Cross-border payment technology defendants should maintain proactive IPR and prior art analysis capabilities as a standard defense toolkit

For R&D teams:

• U.S. Patent Nos. 10,062,107 and 11,620,701 remain issued and enforceable against other parties — fintech companies developing consolidated international payment platforms should conduct thorough FTO analysis against this patent family
• Patent families with continuation relationships (as here, with application Nos. 11/736,583 and 17/948,217) may harbor additional continuation applications not yet asserted

Industry & Competitive Implications

The Intercurrency v. Nium dispute reflects a broader trend of patent assertion activity targeting fintech infrastructure companies as cross-border payment technology matures and patent portfolios in this space become increasingly contested.

Cross-border payment platforms — processing multi-currency transactions across complex regulatory environments — are built on layered software architectures that map naturally onto software patent claims involving consolidated trading and payment systems. As companies like Nium scale globally, they present higher-value assertion targets, attracting NPE attention.

The outcome here suggests that well-capitalized fintech defendants with sophisticated IP defense counsel can negotiate or litigate their way to favorable exits even in plaintiff-friendly venues like the Eastern District of Texas. For Nium, the dismissal with prejudice on these patents clears a specific IP overhang from its Instarem platform’s commercial operations.

For the broader fintech sector, this case signals that cross-border payment patent litigation is active and will likely intensify as the market grows. Companies should treat patent risk management — including portfolio monitoring, FTO analysis, and IPR readiness — as a core operational function rather than a reactive legal concern.
