Bandspeed v. VeSync: 11-Patent Bluetooth AFH Suit Dismissed With Prejudice
Bandspeed, Inc. filed suit in the Western District of Texas asserting 11 patents covering Bluetooth adaptive frequency hopping technology against VeSync’s consumer Bluetooth products and app ecosystem. The case resolved in 258 days with a dismissal with prejudice — all claims extinguished, each side bearing its own legal costs.
Bluetooth AFH Patent Portfolio Assault Ends in Final Dismissal
On 31 January 2024, Bandspeed, Inc. filed a patent infringement action in the Western District of Texas (Case No. 1:24-cv-00116) before Judge David Alan Ezra, asserting 11 US patents directed at Bluetooth adaptive frequency hopping (AFH) technology against VeSync Co., Ltd. The accused products included VeSync’s Bluetooth Classic and Bluetooth LE product lines, the Etekcity ESF24 Smart Fitness Scale, a Bluetooth speaker (Model No. EWN-S12), associated SDKs, driver software, and the VeSync mobile app.
The case concluded on 15 October 2024 when Judge Ezra granted Bandspeed’s Notice of Dismissal, entering an order dismissing all claims, answers, affirmative defenses, and counterclaims with prejudice. Each party was ordered to bear its own costs, expenses, and attorney fees. A dismissal with prejudice is a final adjudication on the merits under res judicata principles, permanently barring Bandspeed from reasserting the same claims against VeSync on these patents.
The 258-day duration from filing to closure suggests the parties likely reached a private resolution — potentially a licence or covenant not to sue — before any substantive merits ruling. The mutual cost-bearing order is consistent with a negotiated settlement rather than a litigated outcome. The public record does not disclose the financial terms, if any, of the arrangement that prompted Bandspeed’s notice of dismissal.

Dismissed with prejudice: what the court order means for both parties
Dismissal with prejudice bars all future re-filing on these claims
A dismissal with prejudice operates as a final judgment on the merits. Under res judicata, Bandspeed cannot refile the same patent infringement claims against VeSync in any US court. The order extinguishes not only Bandspeed’s claims but also any counterclaims and affirmative defenses VeSync had raised, giving both parties a clean slate with hard finality.
Permanent bar to re-filingBandspeed retains patents but surrenders enforcement route against VeSync
Bandspeed’s 11 AFH patents remain valid and enforceable against third parties — the dismissal with prejudice affects only these specific claims against VeSync. However, Bandspeed receives no court-awarded damages or injunctive relief. If the dismissal followed a private licence deal, Bandspeed may still realise commercial value, but the public record is silent on any licensing terms.
Patents survive; VeSync claim foreclosedVeSync achieves finality — litigation risk on these 11 patents eliminated
VeSync secures a permanent resolution: Bandspeed’s 11 Bluetooth AFH patents can no longer be weaponised against it in US litigation on the same factual basis. Each party bears its own costs, so VeSync avoids any fee award. The absence of a merits ruling means VeSync obtained no invalidity finding, leaving those patents fully intact for assertion against VeSync’s competitors.
Litigation risk on 11 patents eliminated11 Bluetooth AFH patents remain live enforcement tools for the broader market
Because no court ruled on validity or infringement, Bandspeed’s AFH patent portfolio retains full offensive potential against other Bluetooth device makers, IoT product companies, and SDK vendors. Competitors of VeSync selling products that implement the 2.4 GHz ISM band AFH kernel or Bluetooth Core Spec 2.0+EDR/4.0 LE protocols should treat this portfolio as an active risk requiring FTO analysis.

Official order — verbatim text
The court’s order adopts Bandspeed’s own Notice of Dismissal, granting it in full and entering the with-prejudice disposition jointly agreed by the parties. The explicit instruction that ‘all claims, answers, affirmative defenses, and counterclaims’ are dismissed is notably comprehensive — it forecloses any latent counterclaim by VeSync as well as Bandspeed’s infringement claims. The mutual cost-bearing term, rather than a fee award, is consistent with a negotiated exit rather than a litigated defeat, though the court makes no finding on the merits of infringement or validity.
US10602528B2 — Bluetooth Adaptive Frequency Hopping Technology
The lead patent, US10602528B2 (App. No. 15/880,933), is one of eleven Bandspeed patents asserted in this action, collectively covering adaptive frequency hopping (AFH) kernel technology for the 2.4 GHz ISM band — the unlicensed spectrum shared by Bluetooth, Wi-Fi, and ZigBee devices. AFH enables Bluetooth radios to dynamically avoid congested or interfered channels, a capability mandated in Bluetooth Core Specification 2.0+EDR and formalised in Version 4.0 LE. The portfolio spans application dates from as early as US09/948499, indicating foundational priority claims in this technical domain.
For any company shipping Bluetooth Classic or Bluetooth LE products — including smart fitness devices, wireless speakers, IoT sensors, or mobile apps that orchestrate Bluetooth connections — this portfolio represents material enforcement risk. Because no invalidity finding was made in this case, all 11 patents retain their presumption of validity. Bandspeed’s decision to assert the full portfolio against a single consumer electronics defendant suggests a licensing strategy calibrated to the breadth of modern Bluetooth product lines rather than narrow product-specific infringement.
Should your Bluetooth product team run an FTO against Bandspeed’s AFH portfolio?
Any organisation commercialising products that implement Bluetooth adaptive frequency hopping — including smart speakers, fitness wearables, smart scales, IoT hubs, Bluetooth SDKs, or companion mobile applications — should treat Bandspeed’s 11-patent portfolio as a live FTO priority. The portfolio covers both the Classic Bluetooth AFH kernel and Bluetooth LE channel selection mechanisms, meaning exposure spans virtually any modern dual-mode Bluetooth chipset or stack implementation.
PatSnap Eureka’s FTO Search Agent can map your product’s Bluetooth stack implementation against each of the 11 asserted patents, surface relevant prior art, identify claim elements with highest infringement risk, and benchmark your exposure against VeSync’s accused product categories.

What this case signals for the Bluetooth IP licensing landscape
A 258-day, 11-patent Bluetooth AFH suit ending in a with-prejudice dismissal raises pointed questions for any IoT or consumer electronics IP team.
Bluetooth AFH patent portfolios are active enforcement tools in 2024
Bandspeed’s willingness to assert 11 patents simultaneously against a mid-market consumer electronics brand signals that AFH-focused NPEs view Bluetooth Classic and LE implementers as viable licensing targets. Companies shipping products using the Bluetooth Core Specification 2.0+EDR or 4.0 LE stack should audit exposure against this portfolio.
Fast resolution without merits ruling suggests private deal — watch for portfolio redeployment
Cases that close in under nine months with a with-prejudice dismissal and mutual cost-bearing typically reflect a confidential settlement or licence. Bandspeed’s 11 patents remain valid and unencumbered against non-VeSync defendants, suggesting the portfolio will continue to be deployed against other Bluetooth device makers, IoT platforms, and SDK vendors.
Bandspeed v Vesync — key questions answered
The with-prejudice dismissal permanently bars Bandspeed from reasserting the same 11 patent claims against VeSync in any US court. Under res judicata, the order operates as a final judgment on the merits of those specific claims, even though no substantive infringement or validity ruling was made. Bandspeed’s patents remain enforceable against all other defendants.
Bandspeed asserted 11 US patents: US10602528B2, US7903608B2, US9379769B2, US7570614B2, US7477624B2, US7027418B2, US8542643B2, US8873500B2, US10791565B2, US9883520B2, and US10887893B2. All relate to Bluetooth adaptive frequency hopping (AFH) technology for the 2.4 GHz ISM band, covering both Bluetooth Classic and Bluetooth LE implementations.
The court’s order reflects the terms agreed by the parties in the dismissal stipulation — neither side was awarded attorney fees or costs. This mutual cost-bearing arrangement is typical of negotiated resolutions and suggests the parties reached a private agreement (potentially a licence or covenant not to sue) rather than litigating to a merits judgment. The public record does not disclose any financial settlement terms.
The accused products included VeSync’s Bluetooth Classic and Bluetooth LE product lines broadly, the Etekcity ESF24 Smart Fitness Scale, a Bluetooth speaker (Model No. EWN-S12), associated SDKs, driver software, and the VeSync mobile app. The allegations centred on use of the 2.4 GHz ISM band, the Bluetooth Core Specification 2.0+EDR, and Bluetooth LE Version 4.0 protocol implementations.
No. Because the case resolved by dismissal before any merits adjudication, no court has ruled on the validity or invalidity of any of the 11 Bandspeed patents. Each patent retains its statutory presumption of validity under 35 U.S.C. § 282. Companies concerned about exposure should consider inter partes review (IPR) petitions or conduct formal FTO analyses, as the patents remain fully enforceable against third parties.
