Future Motion v. Tony Lai: Permanent Injunction Over Floatwheel Electric Skateboard
Future Motion, Inc., maker of the Onewheel self-balancing electric skateboard, sued Tony Lai in Oregon federal court alleging infringement of four utility patents by the Floatwheel Adv and Adv Pro models. After Lai failed to respond, the court entered default judgment and permanently enjoined all U.S. sales and imports of the infringing products across 575 days of proceedings.
Onewheel maker secures permanent ban on Floatwheel clones via default
Future Motion, Inc., the Santa Cruz-based company behind the Onewheel self-balancing electric skateboard, filed suit on 27 November 2023 in the U.S. District Court for the District of Oregon against Tony Lai, the operator behind the Floatwheel brand. The complaint asserted infringement of four U.S. patents — US11590409B2, US10456658B1, US11273364B1, and US9598141B1 — all directed at core technologies in self-balancing, single-wheel electric rideable devices, against the Floatwheel Adv and Adv Pro product lines.
Lai did not respond to the complaint, and the court ultimately entered a default judgment on 24 June 2025 — the court’s final judgment in the matter. The judgment permanently enjoins and restrains Lai from offering, selling, or importing the infringing products into the United States, and critically, from publicly posting content that induces infringement of Future Motion’s asserted patents. The court retained jurisdiction to enforce the terms going forward.
At 575 days from filing to closure, the timeline is notably extended for a default judgment, suggesting the process involved formal service complications or overseas defendant logistics consistent with aftermarket hardware sellers. No damages figure appears in the public record — the injunctive relief alone signals Future Motion’s primary objective was market exclusion rather than monetary recovery. The inducement provision is particularly notable, suggesting Floatwheel’s online presence was a key vector for alleged infringement activity.

Default judgment and permanent injunction: what the ruling means for both parties
Default judgment: liability without a merits contest
A default judgment is entered when a defendant fails to appear or respond to a complaint. The court accepts the plaintiff’s well-pleaded allegations as true and may grant the relief sought. Here, Judge Armistead entered a permanent injunction — one of the most severe remedies in patent law — without Lai mounting any defence. This forecloses future challenges to liability on these patents in this proceeding.
Default — no merits contestFuture Motion secures sweeping U.S. market exclusion
The permanent injunction prohibits Lai from offering, selling, or importing the Floatwheel Adv and Adv Pro models into the United States. The additional restraint on posting content that induces infringement extends the injunction to online channels — a meaningful provision for a product sold primarily through direct-to-consumer web storefronts. Future Motion has effectively removed a direct hardware competitor from the U.S. market through this ruling.
Injunction granted — U.S. market clearedLai faces permanent U.S. sales ban with no path to contest
By failing to respond, Lai lost the opportunity to challenge validity or non-infringement of Future Motion’s four patents. The default judgment binds him permanently, and the court’s retained jurisdiction means any violation risks contempt proceedings. While Lai could theoretically move to vacate the default under FRCP 55(c) or 60(b) by demonstrating good cause, that window narrows over time and typically requires showing a meritorious defence.
Permanently enjoined — no U.S. salesFuture Motion signals aggressive enforcement of its Onewheel IP moat
This ruling, combined with Future Motion’s history of patent enforcement, suggests a deliberate strategy to use its patent portfolio as a moat against aftermarket and clone-device entrants. The inducement restraint is a template other IP holders in the consumer hardware space may seek to replicate. Competitors developing self-balancing single-wheel rideables should conduct FTO analysis against all four asserted patents before commercialising in the U.S.

Official order — verbatim text
The court’s verdict language — permanently enjoining sales, offers, imports, and inducement-related public posting — reflects the full breadth of remedies available under 35 U.S.C. § 271 in a default context. Because no invalidity or non-infringement defence was raised, the four asserted patents stand unrebutted as to this defendant. The retained-jurisdiction clause signals the court anticipates potential enforcement proceedings, consistent with injunctions against parties who may attempt to resume commercial activity under altered branding or channels.
US11590409B2 — self-balancing single-wheel electric rideable systems
The four asserted patents — US11590409B2, US10456658B1, US11273364B1, and US9598141B1 — collectively cover the core engineering of single-wheel self-balancing electric rideables: the control algorithms, mechanical architecture, sensor integration, and stability systems that define the Onewheel product category. The earliest application, US15/063071 (issuing as US9598141B1), reflects foundational IP dating to the mid-2010s, establishing Future Motion as an early mover in a category it largely created.
Collectively, these four patents construct an overlapping coverage matrix that makes designing around Future Motion’s IP portfolio a significant technical and legal challenge. For competitors in the self-balancing rideable space — including aftermarket hardware builders, OEM suppliers, and e-commerce importers — each of these patents represents a separate infringement vector. The Floatwheel case demonstrates that Future Motion monitors the market actively and is prepared to litigate to injunction even against individual operators.
Should your team run an FTO against US11590409B2 and related patents?
Any R&D team or product company developing a single-wheel self-balancing electric rideable for the U.S. market must conduct freedom-to-operate analysis against all four patents asserted in this case. The permanent injunction entered here — covering sales, imports, and online inducement — illustrates the full commercial exposure. This is not limited to direct Onewheel competitors: companies developing adjacent rideable, personal mobility, or robotic balancing platforms should also assess claim scope.
PatSnap Eureka’s FTO Search Agent allows IP and R&D teams to map claim scope across US11590409B2, US10456658B1, US11273364B1, and US9598141B1 simultaneously, identify design-around opportunities, and monitor for continuation filings that may extend Future Motion’s coverage. With Future Motion’s demonstrated enforcement posture, proactive FTO review before U.S. market entry is commercially essential.

What this case signals for the electric rideable IP landscape
Future Motion’s default judgment outcome reinforces its enforcement posture and raises the stakes for any competitor in the self-balancing rideable market.
Four-patent assertion raises the invalidation bar for challengers
Asserting four patents simultaneously against a single product line creates a stacking problem for any potential challenger: all four must be invalidated or designed around to clear the path. The default here means none were tested in litigation, leaving Future Motion’s portfolio intact and unrebutted in this forum.
Inducement-restraint provision extends the injunction to digital channels
The explicit prohibition on posting content that induces infringement is broader than a standard product injunction. For companies selling consumer hardware online, this signals that U.S. courts may extend injunctive relief to cover promotional and instructional content — not just the physical product itself.
Future v Tony — key questions answered
The court entered a default judgment in favour of Future Motion on 24 June 2025. The judgment permanently enjoins Tony Lai from offering, selling, importing, or inducing infringement of Future Motion’s four asserted patents in the United States. The court retained jurisdiction to enforce the terms.
Future Motion asserted four U.S. patents: US11590409B2, US10456658B1, US11273364B1, and US9598141B1. All four relate to self-balancing single-wheel electric rideable technology. The Floatwheel Adv and Adv Pro models were identified as the infringing products.
Beyond prohibiting physical sales and imports, the court’s order restrains Lai from publicly posting information that induces others to infringe Future Motion’s patents. This extends the injunction to online content — tutorials, promotional materials, and platform listings — that could facilitate third-party infringement, making the remedy significantly broader than a standard product-level injunction.
The public record does not specify the cause of delay. However, 575 days is notably long for an unopposed default action. This timeline is consistent with complications in effecting service of process on individual defendants, particularly those potentially located outside the United States, which the court must formally confirm before entering judgment.
A defaulted defendant may move to vacate under FRCP 55(c) or 60(b), but must demonstrate good cause — typically including a meritorious defence, lack of culpable conduct, and no prejudice to the plaintiff. Such motions face a high bar, particularly after a final judgment has been entered and the court has issued a permanent injunction. The window for successful challenge narrows significantly over time.
