Intercurrency Software v. Plus500 Ltd — Dismissed With Prejudice After 182 Days
Intercurrency Software LLC asserted three U.S. patents covering currency trading platform technology against Plus500 Ltd in the Eastern District of Texas. The case closed after just 182 days when Intercurrency voluntarily dismissed all claims with prejudice — permanently extinguishing its right to refile against Plus500 on these patents.
Three fintech patents, one rapid exit: the Plus500 dismissal explained
Filed on 17 April 2024 in the Eastern District of Texas before Judge Rodney Gilstrap, Intercurrency Software LLC brought an infringement action asserting three patents — US10776863B1, US11449930B1, and US10062107B1 — against Plus500 Ltd’s trading platforms and systems. Garteiser Honea PLLC represented the plaintiff; Gillam & Smith LLP appeared for Plus500.
On 16 October 2024, Intercurrency filed a Notice of Voluntary Dismissal under Rule 41(a)(1)(A)(i), dismissing all claims against Plus500 with prejudice. Because Plus500 had not yet answered the complaint or moved for summary judgment, the dismissal was procedurally available without court approval. Judge Gilstrap accepted and acknowledged the notice, formally closing the case. Critically, the with-prejudice designation bars Intercurrency from reasserting these same patent claims against Plus500 in any future action.
The 182-day lifespan — ending before substantive motion practice — suggests the parties likely reached a private resolution, or Intercurrency concluded continued prosecution was commercially unviable against this particular defendant. The public record does not disclose whether any licensing agreement or settlement payment accompanied the dismissal; the court order is silent on that point. The own-costs arrangement is standard for pre-answer voluntary dismissals and does not signal which party held the stronger position on the merits.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, but at a cost
Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss without court approval before the defendant answers or moves for summary judgment. Intercurrency exercised this right but elected the with-prejudice variant — a deliberate choice that permanently forecloses reassertion of these three patents against Plus500. The court’s role was limited to accepting and acknowledging the notice; no merits ruling was issued.
No merits adjudicationWith-prejudice dismissal: Intercurrency’s claims are permanently extinguished
A with-prejudice dismissal carries the force of a final judgment on the merits for claim-preclusion purposes. Intercurrency retains ownership of the three patents and may still enforce them against other parties, but these specific claims against Plus500 cannot be revived. This is a materially different posture from a without-prejudice dismissal, which would preserve the option to refile. The public record does not confirm whether a licensing payment or settlement accompanied this exit.
Claims permanently barred vs. Plus500Plus500 achieves permanent peace on these three patents
Plus500 secured a with-prejudice dismissal without having to answer the complaint, brief a motion, or incur the cost of substantive litigation. The res judicata effect means Intercurrency’s three asserted patents cannot be wielded against Plus500 again in U.S. federal court. Plus500 bears its own legal costs under the order, suggesting no fee-shifting relief was sought or granted — consistent with an early, pre-answer resolution.
Full preclusion achievedFintech trading platform IP: what the swift exit signals for the sector
Early with-prejudice dismissals in EDTX patent cases frequently suggest an out-of-court licensing agreement, though this cannot be confirmed from the public record. For other trading platform operators, the three Intercurrency patents remain live enforcement tools — this case does not affect their validity or enforceability against third parties. Competitors in the CFD and multi-asset trading space should monitor Intercurrency’s filing history for further assertions of this portfolio.

Official order — verbatim text
The court’s order does not resolve any disputed patent claim on its merits — it solely accepts Intercurrency’s voluntary notice under Rule 41(a)(1)(A)(i). The operative legal consequence is the with-prejudice designation, which Judge Gilstrap’s order explicitly confirms: ‘all claims by Plaintiff in the above-captioned case are DISMISSED WITH PREJUDICE.’ The own-costs directive forecloses any fee-shifting argument by either side arising from this case. No validity, infringement, or claim construction findings appear in the record.
US10776863B1, US11449930B1 & US10062107B1 — Currency Trading Platform Technology
The three asserted patents — US10776863B1 (App. No. 16/113289), US11449930B1 (App. No. 17/019359), and US10062107B1 (App. No. 11/736583) — cover electronic systems and methods relating to currency exchange and multi-asset trading platforms. The portfolio spans multiple application generations, with the earliest application number (11/736583) suggesting priority dating that predates the modern CFD and retail FX trading boom, giving Intercurrency potentially broad claim coverage across contemporary platform architectures.
For companies operating electronic trading platforms — particularly in the CFD, FX, and retail multi-asset segments where Plus500 competes — this portfolio represents a non-trivial enforcement risk. The breadth of the three-patent family, combined with Intercurrency’s willingness to file in EDTX before Judge Gilstrap, suggests a commercially sophisticated licensing strategy. Platform operators that have not conducted freedom-to-operate analysis against this portfolio should consider doing so, particularly given the patents’ continued validity post-dismissal.
Should your trading platform team run an FTO against US10776863B1?
Any company operating an electronic trading platform — including CFD brokers, FX platforms, cryptocurrency exchanges, and multi-asset retail trading systems — should assess exposure to the Intercurrency portfolio. The three patents cover platform-level trading and currency exchange functionality that is broadly implemented across the industry. A failure to conduct FTO analysis leaves product and engineering teams exposed to demand letters and EDTX litigation with no advance preparation.
PatSnap Eureka’s FTO Search Agent enables IP and R&D teams to map claim-level coverage across US10776863B1, US11449930B1, and US10062107B1 against your platform’s specific architecture. Eureka surfaces prior art, identifies claim dependencies, and flags continuation risk from related application families — giving you a defensible, documented clearance position before any enforcement action is filed.

What this case signals for the fintech trading platform IP landscape
A pre-answer, with-prejudice exit in EDTX typically reflects calculated strategy — not weakness. Here is what practitioners should note.
With-prejudice dismissals are permanent — third parties are not protected
The dismissal resolves only Intercurrency’s claims against Plus500. The three asserted patents — US10776863B1, US11449930B1, and US10062107B1 — remain in force and can be asserted against any other trading platform operator. Companies in the CFD, FX, and multi-asset trading space should treat this portfolio as an active enforcement risk.
EDTX pre-answer dismissals often signal undisclosed licensing activity
Cases that close before the defendant files an answer — particularly in the Eastern District of Texas under Judge Gilstrap — statistically correlate with private licensing resolutions. While no agreement is on the public record here, the speed of resolution and each-party-bears-costs arrangement is consistent with a negotiated exit rather than a unilateral retreat by Intercurrency.
Intercurrency v Plus500 — key questions answered
The with-prejudice dismissal under Rule 41(a)(1)(A)(i) permanently bars Intercurrency Software from reasserting the three patents — US10776863B1, US11449930B1, and US10062107B1 — against Plus500 Ltd in any future U.S. federal court action. It does not affect Intercurrency’s ability to assert the same patents against other defendants, as the preclusive effect runs only between the specific parties to this case.
No. The case was voluntarily dismissed before Plus500 answered the complaint or any substantive motion was filed. Judge Gilstrap’s order contains no validity, infringement, or claim construction findings. The patents US10776863B1, US11449930B1, and US10062107B1 remain in force with their presumption of validity intact.
The Eastern District of Texas, particularly before Judge Rodney Gilstrap, is a historically plaintiff-favoured patent venue known for efficient case management and substantial patent litigation experience. EDTX’s local patent rules and scheduling orders are well-established, making it a frequent choice for patent licensing entities asserting fintech and software patents. Venue challenges are possible but were not reached in this case given the pre-answer dismissal.
The order directs each party to bear its own costs, expenses, and attorneys’ fees, which forecloses any fee-shifting claim arising from this specific case. It does not, however, represent a finding under 35 U.S.C. § 285 that the case was exceptional — no such analysis was conducted. The arrangement is procedurally standard for pre-answer voluntary dismissals and should not be read as a merits assessment of either party’s litigation position.
The complaint identified Plus500’s trading platforms and systems as the accused products. Plus500 Ltd is a publicly listed multi-asset trading platform provider and CFD broker. The specific technical features of Plus500’s platform alleged to infringe the three Intercurrency patents were not disclosed in the publicly available court record before the case was dismissed.
