Razor USA & Shane Chen v. Jetson Electric Bikes: Hoverboard Patent Dispute Dismissed With Prejudice
Razor USA LLC and inventor Shane Chen filed a four-patent infringement action against Jetson Electric Bikes LLC targeting 25 hoverboard models. The case resolved by stipulated dismissal with prejudice after 351 days in the Eastern District of New York, with each party bearing its own costs — a structure that typically signals a negotiated resolution.
Four Hoverboard Patents, 25 Products, One Stipulated Exit
On October 23, 2023, Razor USA LLC and inventor Shane Chen filed a patent infringement complaint in the U.S. District Court for the Eastern District of New York against Jetson Electric Bikes LLC. The plaintiffs asserted four patents — USRE049608E, USD0739906S, USRE046964E, and US8738278B2 — covering hoverboard technology, and accused 25 distinct Jetson hoverboard models of infringement, ranging from the Flash and Lumino to the J-Beat All Terrain and Plasma X Lava Tech.
The case closed on October 8, 2024, via a stipulation of dismissal with prejudice filed jointly by both parties under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All claims were dismissed with finality, and the parties agreed each would bear its own attorneys’ fees and costs. A dismissal with prejudice bars the plaintiffs from re-filing the same claims against Jetson on these patents, making the resolution legally final.
The 351-day duration and the mutual cost-bearing structure are consistent with a negotiated settlement reached before any substantive court rulings — though the terms of any underlying agreement are not part of the public record. The breadth of Jetson’s accused product line (25 models) and the involvement of both a corporate plaintiff and the original inventor suggest the plaintiffs had a strong assertion posture, which may have incentivised Jetson to resolve the matter privately rather than contest validity or non-infringement through trial.

Dismissed with prejudice: what the stipulated exit means for both sides
Rule 41(a)(1)(A)(ii) dismissal with prejudice explained
A stipulated dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires agreement from all parties and, when filed with prejudice, permanently extinguishes the asserted claims. Razor and Chen cannot re-litigate these specific infringement allegations against Jetson on the four asserted patents. Courts treat this as a final adjudication on the merits for res judicata purposes, even though no substantive ruling was issued.
Permanent bar on re-filingRazor and Chen give up re-filing rights — suggesting a trade-off
Accepting a with-prejudice dismissal means Razor USA and Shane Chen permanently relinquished the right to sue Jetson on these four patents for the accused products. In practice, plaintiffs typically accept this only when they have obtained value elsewhere — such as a licensing agreement or product design change — though no such terms are disclosed in the public record. The mutual cost-bearing clause further suggests neither party claimed a clear litigation win.
No re-filing permittedJetson avoids a merits ruling but pays an unknown price
Jetson Electric Bikes secured dismissal of all claims without any court finding of infringement, validity, or damages. However, dismissal with prejudice does not equate to a defendant victory on the merits — it simply ends this litigation. The absence of a fee award to Jetson (an ‘exceptional case’ finding under 35 U.S.C. § 285) suggests the court never had occasion to assess the strength of the claims, consistent with pre-merits resolution.
No merits adjudication25 accused SKUs — scope signals serious IP enforcement posture
The breadth of accused products — 25 named hoverboard models — suggests Razor and Chen pursued a comprehensive enforcement strategy targeting Jetson’s full product lineup rather than isolated models. For other hoverboard manufacturers, the patents remain enforceable against third parties; the dismissal with prejudice binds only Jetson. Competitors with overlapping designs should treat the four asserted patents as live enforcement risks.

Official order — verbatim text
The stipulation’s express invocation of Rule 41(a)(1)(A)(ii) and the with-prejudice designation are legally precise choices: the parties elected the most final form of voluntary dismissal available, foreclosing any future re-filing of these claims by Razor or Chen against Jetson. The mutual cost-bearing clause — departing from the default where a prevailing party might seek fees — is consistent with a privately negotiated resolution where both sides accepted a commercial trade-off rather than pursuing a litigation outcome. No infringement finding, no validity ruling, and no damages award appear in the public record.
USRE049608E, USD0739906S, USRE046964E & US8738278B2 — Hoverboard Technology Portfolio
The four asserted patents collectively cover both the functional and ornamental aspects of self-balancing hoverboard technology. USRE049608E and USRE046964E are USPTO reissues, indicating the original patents underwent post-grant correction or scope refinement — a process that subjects the claims to fresh examination and often results in more defensible scope. USD0739906S protects the ornamental design of the device, adding a trade dress-adjacent enforcement layer. US8738278B2 covers foundational control system technology dating to application US13/764781.
The portfolio’s combination of utility reissues and a design patent reflects a layered enforcement strategy: utility patents capture functional copycats while the design patent targets visual imitations. For competitors in the self-balancing scooter and personal electric mobility market, this multi-vector coverage makes design-around strategies significantly more complex. The reissue status of two patents suggests Razor and Chen have already stress-tested claim scope, reducing the likelihood that a straightforward prior art challenge would succeed.
Should you run an FTO against USRE049608E and the Razor-Chen hoverboard portfolio?
Any company designing, importing, or selling self-balancing hoverboards or personal electric scooters in the US market should treat this four-patent portfolio as a live clearance risk. The 25-product scope of the Jetson assertion demonstrates that Razor and Chen are willing to pursue broad product-line enforcement — not just flagship models. R&D teams developing hoverboard drive systems, balance sensors, or rider platforms should map their designs against all four patents before commercialisation.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against USRE049608E, USD0739906S, USRE046964E, and US8738278B2 simultaneously, flagging claim-level overlap and identifying prior art that may support design-around or challenge strategies. Given the reissue status of two patents, Eureka’s validity analysis layer can also surface whether any intervening art weakens the revised claim scope — a critical input before entering or expanding in this product category.

What this case signals for the hoverboard and personal mobility IP landscape
A broad 25-product assertion by a patent-backed inventor and brand resolved quietly — the pattern has clear implications for the sector.
Shane Chen’s patent portfolio is an active enforcement asset
The inclusion of inventor Shane Chen as a co-plaintiff alongside Razor USA signals a coordinated enforcement structure where both the brand licensee and the original inventor pursue infringers jointly. Companies in the self-balancing scooter and hoverboard space should assume the Chen-Razor patent portfolio is being actively monitored and enforced — not just held defensively.
Re-issued patents carry heightened validity confidence
Two of the four asserted patents are reissues (USRE049608E and USRE046964E), meaning the USPTO reviewed and confirmed their scope post-grant. Reissued patents are often harder to invalidate in IPR proceedings because they have already survived one round of USPTO scrutiny. Challengers relying on an IPR strategy should account for this elevated threshold.
Razor v Jetson — key questions answered
Razor USA LLC and Shane Chen asserted four patents: USRE049608E and USRE046964E (both reissue utility patents covering self-balancing hoverboard technology), USD0739906S (a design patent for the ornamental appearance of a hoverboard), and US8738278B2 (a utility patent covering a self-balancing vehicle control system). All four were asserted in the Eastern District of New York.
The case was resolved by a stipulated dismissal with prejudice filed jointly by all parties under Fed. R. Civ. P. 41(a)(1)(A)(ii) on October 8, 2024. All claims were dismissed with prejudice, and each party agreed to bear its own attorneys’ fees and costs. No court ruling on infringement, validity, or damages was issued.
A dismissal with prejudice is legally final. Razor USA LLC and Shane Chen are permanently barred from re-filing the same patent infringement claims against Jetson Electric Bikes LLC based on the four asserted patents and the 25 accused product models. The res judicata effect of this dismissal treats the matter as fully and finally adjudicated, even though no substantive court ruling was made.
The complaint named 25 Jetson hoverboard models, including the Flash, Hali X, Impact, Input, J-Beat All Terrain, Litho X, Lumino, Magma All-Terrain, Mojo Dynamic Sound, Pixel, Plasma Luminous All-Terrain, Plasma X Lava Tech, Prism All-Terrain, Rave, Remix and Go-Kart Combo, Rogue, Rumble, Sphere, Spin, Stereofly, Strike, Sync All-Terrain Stereo, Tracer, X10, and Zone hoverboards.
Yes. The dismissal with prejudice binds only the parties to this action — Razor USA, Shane Chen, and Jetson Electric Bikes. The four patents (USRE049608E, USD0739906S, USRE046964E, and US8738278B2) remain in force and enforceable against third parties. No invalidity finding or claim limitation was issued in this case, so the patents retain their full pre-litigation scope against other potential infringers.
