Hangzhou Chic v. Urbanmax & Gyroor: Federal Circuit Affirms Hoverboard Design Patent Win
Hangzhou Chic Intelligent Technology and Unicorn Global secured a Federal Circuit affirmance against Urbanmax, Gyroor US, and eight Tomoloo storefronts for infringing four USD design patents covering self-balancing vehicles. The appeal ran 547 days before the court found no reversible error in the decision below.
Four Design Patents, Ten Defendants, One Federal Circuit Affirmance
Hangzhou Chic Intelligent Technology Co., Ltd. and Unicorn Global, Inc. — collectively the IP holders behind a portfolio of self-balancing hoverboard designs — brought an infringement action against a set of marketplace sellers including Urbanmax, Gyroor US, and multiple Tomoloo-branded storefronts. The case centred on four U.S. design patents (USD784195, USD737723, USD785112, USD738256) covering the ornamental appearance of human-machine interaction vehicles, commonly known as hoverboards or self-balancing scooters.
The matter proceeded to the Federal Circuit as Case No. 24-1471, filed 14 February 2024 and closed 14 August 2025. The court’s disposition — ‘ORDERED AND ADJUDGED: AFFIRMED’ — confirms that the appellate panel found no reversible error in the lower court’s handling of the infringement claims. The basis of termination is recorded as ‘Appeal Dismissed,’ which in Federal Circuit practice is consistent with the appeal being resolved on the merits through affirmance rather than a procedural dismissal on grounds unrelated to substance.
The 547-day appellate timeline suggests a fully-briefed appeal rather than a summary disposition, implying the defendants mounted substantive challenges to the underlying findings. What drove the outcome — whether design patent claim scope, ordinary observer test application, or a preliminary injunction challenge — is not fully detailed in the public record. The affirmance leaves the original infringement ruling intact and removes the appellate avenue for the named seller-defendants.

Federal Circuit affirms: what the ruling means for both parties
Affirmance means the lower decision stands in full
When the Federal Circuit issues an ‘AFFIRMED’ disposition, it signals the appellate panel found no reversible legal or factual error in the tribunal below. The original infringement findings — including any injunctive or damages relief — remain operative. The defendants exhausted their appellate right at this level; the only remaining avenue would be a petition for rehearing en banc or certiorari to the Supreme Court, both of which face high thresholds.
No reversible error foundChic and Unicorn Global’s design rights emerge strengthened
For Hangzhou Chic and Unicorn Global, the affirmance validates the enforceability of all four USD design patents against marketplace sellers. The ruling reinforces that the ornamental design scope of these self-balancing vehicle patents is sufficient to capture competing products. This outcome typically signals that further enforcement actions against similarly situated sellers would face a strengthened precedential backdrop at the Federal Circuit level.
Design patents upheldUrbanmax, Gyroor, and Tomoloo entities left without appellate cover
The named defendants — marketplace sellers operating under Urbanmax, Gyroor US, and multiple Tomoloo storefronts — have now exhausted their Federal Circuit appeal. The affirmance closes the appellate avenue and leaves the original liability findings intact. Continued sales of the accused products would expose these entities to contempt or further enforcement proceedings. Other sellers of visually similar hoverboard designs should treat this ruling as a heightened-risk signal.
Appeal rights exhaustedHigher enforcement bar for self-balancing vehicle design claims
The Federal Circuit’s affirmance raises the practical cost of contesting these four design patents through appeal. For the broader self-balancing vehicle and personal mobility sector — where numerous marketplace sellers compete on platform marketplaces — this ruling suggests that design patent holders with registered USD rights can sustain enforcement actions through appellate review. Companies sourcing or reselling hoverboard products should prioritise design clearance before market entry.

Official order — verbatim text
The Federal Circuit’s order — ‘ORDERED AND ADJUDGED: AFFIRMED’ — is a merits disposition confirming that the panel applied its standard appellate review and found no reversible legal error or clearly erroneous factual findings in the lower court’s infringement analysis of the four USD design patents. In design patent appeals, the Federal Circuit typically applies de novo review to claim construction and a clearly erroneous standard to the ordinary observer infringement test findings. The affirmance therefore suggests the lower court’s scope and infringement conclusions were well-supported on both legal and evidentiary grounds.
USD784195, USD737723, USD785112 & USD738256 — Self-Balancing Vehicle Designs
The four asserted patents are U.S. design patents (USD series) originating from applications US29/556275, US29/511915, US29/556300, and US29/511924. Design patents protect the ornamental appearance of an article of manufacture — in this case, the visual configuration of self-balancing two-wheeled personal mobility vehicles commonly marketed as hoverboards. The USD737723 and USD738256 applications (29/511915 and 29/511924) appear to represent an earlier filing wave, with USD784195 and USD785112 (29/556275 and 29/556300) comprising a subsequent continuation or related design family.
The strategic value of this four-patent design stack lies in its ability to cover multiple ornamental angles and configurations of the same product category, significantly narrowing design-around space for competitors. In the self-balancing vehicle market — heavily populated by Chinese manufacturers and U.S. marketplace sellers — registered USD design rights have proven to be an effective enforcement tool. The Federal Circuit’s affirmance of these patents against ten named sellers reinforces their commercial durability and raises the cost of infringement defence for future accused parties.
Should you run an FTO against USD784195, USD737723, USD785112 & USD738256?
Any company manufacturing, importing, distributing, or retailing self-balancing scooters or hoverboards in the U.S. market should treat these four design patents as active enforcement risks. The Federal Circuit’s affirmance means the patents have now survived appellate scrutiny — a significant bar. Marketplace sellers on Amazon, Walmart, or similar platforms are particularly exposed given the Schedule A enforcement model validated by this litigation. Even modest visual similarity to the patented designs could trigger action.
PatSnap Eureka’s FTO Search Agent can map your product’s visual design against the ornamental claims in USD784195, USD737723, USD785112, and USD738256, identify the full design patent family held by Hangzhou Chic and Unicorn Global, and flag related pending applications. Eureka’s prior art and design patent landscaping tools allow R&D and product teams to document design-around clearance before launch — reducing litigation exposure at the source.

What this case signals for the personal mobility IP landscape
A Federal Circuit affirmance in a multi-defendant hoverboard design patent case sends a clear signal to marketplace sellers and sourcing teams.
Marketplace sellers face compounded risk from design patent affirmances
The involvement of ten named defendants — spread across multiple storefronts — illustrates the enforcement strategy of targeting platform-based sellers collectively. An affirmance at the Federal Circuit means each defendant must now comply with the original order. Brands sourcing similar self-balancing products from third-party manufacturers should audit visual design proximity to USD784195, USD737723, USD785112, and USD738256 immediately.
Four design patents covering one product category is a meaningful coverage stack
Asserting four USD design patents in a single infringement action — all directed at self-balancing vehicle aesthetics — suggests a portfolio-based enforcement posture. Each patent covers a distinct ornamental angle or configuration, making design-around strategies more difficult. Competitors and distributors should evaluate whether their products avoid all four visual footprints, not just the most prominent patent in the set.
Hangzhou v PARTNERSHIP — key questions answered
The Federal Circuit affirmed the lower court’s infringement ruling against Urbanmax, Gyroor US, and multiple Tomoloo storefronts. The court found no reversible error in the infringement findings covering four USD design patents (USD784195, USD737723, USD785112, USD738256) directed at self-balancing hoverboard vehicle designs. The case closed 14 August 2025.
Four U.S. design patents were asserted: USD784195 (app. 29/556275), USD737723 (app. 29/511915), USD785112 (app. 29/556300), and USD738256 (app. 29/511924). All four cover the ornamental design of self-balancing human-machine interaction vehicles, commonly known as hoverboards. The patents are held by Hangzhou Chic Intelligent Technology Co., Ltd. and Unicorn Global, Inc.
An affirmance by the Federal Circuit means the appellate panel found no reversible legal or factual error in the lower court’s infringement ruling. For defendants Urbanmax, Gyroor US, and the Tomoloo entities, this closes the appeal avenue and leaves original liability findings — including any injunctions or damages awards — fully in force. Continued sale of infringing products could expose defendants to contempt proceedings.
A Schedule A complaint names a large group of marketplace sellers as defendants in a single action, typically identified by their online storefront rather than corporate name. In this case, the defendants are identified as ‘The Partnership and Unincorporated Associations Identified on Schedule A,’ with Urbanmax, Gyroor US, and multiple Tomoloo storefronts listed. This enforcement model is common in consumer product IP cases targeting marketplace platforms.
The Federal Circuit’s affirmance strengthens the enforceability of the four USD design patents and narrows design-around options for competing hoverboard sellers. Companies selling self-balancing vehicles in the U.S. should conduct FTO analysis against USD784195, USD737723, USD785112, and USD738256. The affirmance signals that these patents will withstand appellate challenge, making pre-launch design clearance materially more important.
