Intercurrency Software vs. Aux Cayes FinTech: Voluntary Dismissal in FinTech Patent Case

Introduction

In a case that underscores the complex litigation calculus facing FinTech patent plaintiffs, Intercurrency Software, LLC voluntarily dismissed its patent infringement claims against Aux Cayes FinTech Co. Ltd. — operator of the OKX and OKCoin cryptocurrency exchange platforms — with prejudice just months after filing. Case No. 2:24-cv-00117, decided before Chief Judge Rodney Gilstrap in the Eastern District of Texas, involved three U.S. patents directed at currency exchange and financial transaction technologies.

Filed on February 20, 2024, and formally closed on January 12, 2026, the case lasted 692 days in total — yet the operative dismissal came far earlier in the proceedings. For patent attorneys, IP professionals, and R&D leaders operating in the cryptocurrency and FinTech space, this case raises important questions about assertion strategies, venue selection, and the realities of litigating software patents in one of the nation’s most active patent courts.

Case Overview

The Parties

The Patents at Issue

Three U.S. patents formed the basis of Intercurrency’s infringement claims. All three patents fall within the domain of **FinTech patent infringement**, specifically software-implemented financial transaction systems — a category that continues to face significant validity scrutiny under 35 U.S.C. § 101 following Alice Corp. v. CLS Bank International.

• • U.S. Patent No. 10,776,863 — directed at currency exchange software systems
• • U.S. Patent No. 11,449,930 — covering financial transaction processing methods
• • U.S. Patent No. 10,062,107 — relating to earlier currency conversion technologies

The Accused Products

The platforms accused of infringement — **OKX** and **OKCoin** — are full-featured cryptocurrency exchange platforms offering currency conversion, trading, and financial transaction processing at scale. Their core exchange functionalities were the apparent focus of Intercurrency’s infringement theory.

Legal Representation

Plaintiff Intercurrency Software was represented by **Christopher A. Honea** of **Garteiser Honea PLLC**, a Texas-based firm with an established practice in patent assertion and NPE litigation. No defendant counsel is reflected in the available case record, which is consistent with an early voluntary dismissal before formal responsive pleadings were likely required.

Litigation Timeline & Procedural History

The case was filed on February 20, 2024, and the voluntary dismissal occurred on May 28, 2024. The formal administrative closure of the case was on January 12, 2026, which accounts for the longer stated duration in the court record.

**Venue selection** in the Eastern District of Texas — specifically before Chief Judge Rodney Gilstrap in Marshall — was a deliberate strategic choice. Judge Gilstrap’s docket historically represents one of the highest volumes of patent litigation in the United States, and the court is widely regarded as plaintiff-favorable in terms of scheduling and trial access.

The case was filed as part of a **consolidated docket**, with the court’s order specifically directing that the remaining consolidated cases remain open while closing only Member Case No. 2:24-cv-00117-JRG. This structure suggests Intercurrency pursued parallel litigation against multiple defendants simultaneously — a common NPE enforcement strategy.

The total docket duration of 692 days reflects administrative closure timing rather than active litigation, as the dismissal itself occurred within approximately 97 days of filing.

The Verdict & Legal Analysis

Outcome

The case concluded via **voluntary dismissal with prejudice** pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), filed by Plaintiff Intercurrency Software LLC. Chief Judge Gilstrap accepted and acknowledged the dismissal, ordering that:

• • All claims against Aux Cayes FinTech Co. Ltd. and OK Group are **dismissed with prejudice**
• • **Each party bears its own costs, expenses, and attorneys’ fees**
• • All pending relief requests are **denied as moot**

No damages were awarded. No injunctive relief was granted. The dismissal with prejudice means Intercurrency **cannot re-file** the same claims against the same defendants in any federal court.

Verdict Cause Analysis

The record reflects an **infringement action** as the asserted cause — meaning Intercurrency alleged that OKX and OKCoin’s exchange functionalities directly infringed one or more claims across the three asserted patents. However, the case did not reach claim construction, summary judgment, or trial.

A voluntary dismissal this early — before a defendant has served an answer or motion for summary judgment — is often driven by one or more of the following strategic realities:

1. Settlement reached: The parties may have negotiated a private licensing agreement, with dismissal as a condition. The court’s order that each party bears its own fees is consistent with a structured resolution.
2. Validity risk assessment: Defendants in FinTech patent cases frequently signal early intentions to file inter partes review (IPR) petitions at the USPTO. Faced with potential invalidation of software patents already vulnerable under § 101, plaintiffs may elect to exit litigation before spending significant resources.
3. Claim mapping deficiencies: Early defendant communications or informal claim charts may have revealed weaknesses in Intercurrency’s infringement theory against OKX/OKCoin’s specific implementation.

Legal Significance

This case adds to a broader pattern of **early-stage NPE dismissals** in FinTech patent litigation, particularly where software patents covering currency conversion or transaction processing face the twin threats of § 101 eligibility challenges and IPR petitions. The patents here — particularly the older ‘107 patent with a 2007 priority application — may carry claim language susceptible to abstract idea challenges under *Alice*.

The **consolidated case structure** is also noteworthy. Patent plaintiffs who file against multiple defendants simultaneously often settle with individual defendants on confidential terms, creating an information asymmetry that benefits early-settling defendants.

Strategic Takeaways

For Patent Holders:

• • Early voluntary dismissal preserves relationship capital and avoids adverse claim construction rulings that could damage the broader portfolio’s licensing value.
• • Asserting patents in consolidated actions against multiple defendants requires careful sequencing — settling strategically with one defendant can generate licensing revenue while avoiding unfavorable precedent.

For Accused Infringers:

• • Aggressive early signaling — including pre-answer communications about IPR petitions and § 101 vulnerabilities — can accelerate plaintiff reconsideration of litigation economics.
• • The absence of attorneys’ fee recovery (each party bears own costs) highlights the importance of early case assessment; fee-shifting under Octane Fitness requires demonstrating an “exceptional case,” which is difficult pre-answer.

For R&D Teams:

• • Cryptocurrency exchange platforms must maintain robust **freedom-to-operate (FTO)** analyses for core transaction processing and currency conversion functionalities, which remain active NPE targets.
• • Building detailed technical documentation distinguishing your platform’s implementation from asserted patent claims supports early resolution.

Industry & Competitive Implications

The FinTech and cryptocurrency sector continues to attract significant NPE patent assertion activity. Currency conversion software, exchange matching engines, and transaction processing systems represent functionally rich targets for patent portfolios developed during the early internet and financial software era.

OKX’s global scale makes it a visible and commercially attractive litigation target, despite the jurisdictional complexities of suing a foreign-domiciled entity. Aux Cayes FinTech’s ability to resolve this matter before significant litigation costs accrued represents a favorable outcome for the defendant.

For the broader crypto exchange industry — including Coinbase, Kraken, Binance.US, and similar platforms — this case signals continued NPE attention to core exchange functionalities. Companies operating in this space should proactively audit their exposure to software patents covering **multi-currency transaction processing**, **exchange rate conversion algorithms**, and **financial data processing systems**.

The case also reflects the continuing relevance of the **Eastern District of Texas** as a venue of choice for patent plaintiffs, notwithstanding post-TC Heartland venue constraints — particularly when defendants have sufficient U.S. contacts.
