AIRWALLEX PTY. LTD. et al. v. Intercurrency Software LLC

This case involves an inter partes review (IPR) proceeding, IPR2025-01446, before the Patent Trial and Appeal Board (PTAB) between AIRWALLEX PTY. LTD. as petitioner and Intercurrency Software LLC as patent owner. Airwallex, along with its subsidiaries AIRWALLEX (SINGAPORE) PTE. LTD. and AIRWALLEX USA LLC, is a multinational financial technology operating company based in Australia. It provides a digital payment platform and solutions for businesses and individuals, facilitating global payments, currency exchange, and financial operations. Conversely, Intercurrency Software LLC is identified as a patent assertion entity (PAE) or non-practicing entity (NPE), primarily engaged in IP licensing and enforcement related to currency trading and financial software, rather than offering its own commercial products.

The core of the dispute revolves around US Patent 11620701, which Intercurrency Software LLC asserted against Airwallex. This patent generally pertains to "Advanced financial platform methods" and "currency exchange and international payment processing space," specifically covering "software-implemented methods or systems related to multicurrency transactions." The alleged infringement by Airwallex involved its digital payment and currency exchange services, including those supporting international invoices, global payments, and foreign exchange rates, which Intercurrency Software claimed utilized the technology described in its patent.

The IPR was filed on August 29, 2025, challenging the validity of US Patent 11620701 before the Patent Trial and Appeal Board. This PTAB action ran parallel to an underlying patent infringement lawsuit, Intercurrency Software LLC v. Airwallex (Singapore) Pty. Ltd. et al. (Case No. 2:24-cv-01011), filed in the U.S. District Court for the Eastern District of Texas. The Eastern District of Texas is a prominent venue for patent litigation, often favored by patent plaintiffs due to its efficient patent docket and established procedural rules. The IPR proceeding ultimately concluded in a settlement on October 2, 2025. This case is notable as it exemplifies an NPE (Intercurrency Software LLC) asserting its fintech-related patent portfolio against a significant operating company in the global payments and foreign exchange industry (Airwallex), with the IPR serving as a defensive strategy by the accused infringer, ultimately leading to a negotiated resolution rather than a full judicial determination.

The patent infringement litigation, Intercurrency Software LLC v. Airwallex (Singapore) Pty. Ltd. et al. (Case No. 2:24-cv-01011), commenced in the U.S. District Court for the Eastern District of Texas, ran in parallel with an Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB). The case ultimately concluded in a settlement, leading to the dismissal of both proceedings.

Here is a chronological overview of the key legal developments and outcomes:

• 2024-12-09 – Complaint Filed: Intercurrency Software LLC initiated the patent infringement lawsuit against Airwallex (Singapore) Pty. Ltd. in the U.S. District Court for the Eastern District of Texas. The lawsuit asserted infringement of US Patent 11620701.
• 2025-01-23 – Service of Process: Airwallex was formally served with the complaint via its U.S. subsidiary, Airwallex US, LLC.
• 2025-04-18 – First Amended Complaint Filed: Intercurrency Software LLC filed a First Amended Complaint for Patent Infringement. This document included references to "IPR2025-01446," indicating that Airwallex was already preparing or had initiated its IPR challenge even before the formal IPR filing date.
• 2025-08-29 – IPR Petition Filed: AIRWALLEX PTY. LTD., along with its subsidiaries, filed an Inter Partes Review petition (IPR2025-01446) before the PTAB, challenging the validity of US Patent 11620701.
• 2025-09-19 – District Court Case Dismissed: The U.S. District Court for the Eastern District of Texas issued an "ORDER DISMISSING CASE WITH PREJUDICE," signed by District Judge Rodney Gilstrap. This dismissal was a result of a confidential settlement reached between Intercurrency Software LLC and Airwallex. Given the relatively early stage of the litigation (less than a year from filing), substantive pre-trial motions (such as motions to dismiss, transfer, or stay pending IPR), claim construction proceedings, or extensive discovery milestones were likely avoided due to the settlement.
• 2025-10-02 – IPR Concludes in Settlement: Following the dismissal of the district court litigation, the parallel IPR proceeding (IPR2025-01446) before the PTAB also concluded in a settlement. This indicates a comprehensive resolution of the dispute covering both the district court claims and the validity challenge at the PTAB.
