Bandspeed v. MPOW Technology: 8-Patent Bluetooth Infringement Action Dismissed
Bandspeed, Inc. asserted eight Bluetooth patents against MPOW Technology’s wireless earbuds and ATS3015 chipset products in the Western District of Texas. After 692 days of litigation, Bandspeed voluntarily dismissed all claims without prejudice before MPOW filed any answer — leaving the door open for refiling.
Bluetooth Patent Portfolio Assault Ends Without Adjudication
Bandspeed, Inc. filed suit against MPOW Technology Co., Ltd. on 19 May 2023 in the Western District of Texas before Judge David Alan Ezra, asserting eight U.S. patents spanning Bluetooth Classic and Bluetooth LE communications technology. The accused products included MPOW’s MX3 True Wireless Earbuds, the mpow-432 and mpow-480 wireless earbud lines, and the ATS3015 Bluetooth chipset — a component central to both Classic and LE product families.
On 10 April 2025, Bandspeed filed a notice of voluntary dismissal without prejudice pursuant to Fed. R. Civ. P. Rule 41(a)(1)(A)(i), citing that MPOW had not yet served an answer or motion for summary judgment. This procedural posture made dismissal a unilateral right for the plaintiff, requiring no court order. The case closed after 692 days without any merits determination, claim construction ruling, or invalidity finding against any of the eight asserted patents.
The nearly two-year duration before a pre-answer dismissal is notable and may suggest extended licensing negotiations, a parallel IPR or inter partes review process, or strategic repositioning of the patent portfolio. Because the dismissal is without prejudice, Bandspeed retains the right to refile against MPOW or assert the same patents against other Bluetooth audio product makers. The absence of defendant counsel on record throughout is consistent with an early-stage default risk or settlement leverage dynamic that the public record does not fully resolve.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Under Fed. R. Civ. P. Rule 41(a)(1)(A)(i), a plaintiff may dismiss its own action without a court order if the defendant has not yet served an answer or motion for summary judgment. MPOW never filed either, giving Bandspeed an unconditional right to exit. No judicial approval was needed, and the court issued no substantive ruling on the merits of any claim.
No court order requiredWithout prejudice: the case can be refiled
The verdict text explicitly states dismissal ‘without prejudice,’ meaning Bandspeed’s infringement claims against MPOW survive legally — they can be reasserted in a future action. This contrasts with a dismissal with prejudice, which would bar refiling on the same claims. The without-prejudice outcome preserves Bandspeed’s full enforcement options across its Bluetooth patent portfolio.
Refiling remains possibleMPOW escapes judgment — but patent risk persists
MPOW Technology avoids any infringement finding, damages award, or injunction. However, because no invalidity ruling was issued against any of the eight asserted patents, MPOW cannot rely on this dismissal as a shield in future litigation. The ATS3015 chipset and associated earbud products remain potentially exposed if Bandspeed — or an assignee of its portfolio — refiles.
No invalidity ruling obtainedEight live Bluetooth patents remain enforceable
The dismissal without prejudice leaves all eight Bandspeed Bluetooth patents fully enforceable. Other Bluetooth audio product makers — particularly those using similar chipsets or implementing Bluetooth 5.0 Classic and LE dual-mode architecture — should note that this portfolio has not been adjudicated or invalidated. The case may signal ongoing licensing activity rather than abandonment of enforcement.

Official order — verbatim text
The verdict text invokes Rule 41(a)(1)(A)(i) and confirms the without-prejudice designation explicitly. The plaintiff’s reliance on Rule 41(a)(1)(B) to justify the without-prejudice character — noting MPOW had not yet answered — is procedurally standard but significant: it confirms no substantive litigation activity constrained the exit. For Bandspeed, this preserves all claims. For MPOW, the absence of an answer-on-file means no counter-arguments, invalidity contentions, or affirmative defenses were ever formally lodged, leaving the patent record entirely uncontested.
US7903608B2 — Bluetooth wireless communication frequency hopping
The eight asserted patents — anchored by US7903608B2 (application US12/352595) and spanning a family filed as early as US09/948499 — cover foundational aspects of Bluetooth wireless communications including adaptive frequency hopping, channel access coordination, piconet management, and dual-mode Classic and LE transceiver architecture. The portfolio spans roughly a decade of Bluetooth standards development, from early 802.15 implementations through Bluetooth 5.0 era innovations, suggesting Bandspeed holds IP that intersects with multiple generations of the Bluetooth specification.
For the Bluetooth audio sector, this portfolio is strategically significant because it targets both chipset-level implementation (ATS3015) and end-product-level functionality (True Wireless Stereo earbuds, ANC earbuds). A patent holder asserting both layers simultaneously creates compounding liability risk for OEMs who neither design their own chips nor independently validate component-level FTO. Companies competing in the Bluetooth 5.0 TWS and ANC audio segment — a market worth tens of billions annually — should treat this multi-generational portfolio as a live enforcement risk.
Should you run an FTO analysis against Bandspeed’s Bluetooth patent portfolio?
If your organisation designs, manufactures, or distributes Bluetooth Classic or Bluetooth LE audio products — including TWS earbuds, ANC headphones, Bluetooth speakers, or wireless audio chipsets — the eight Bandspeed patents asserted in this case warrant a formal freedom-to-operate assessment. The portfolio’s breadth across frequency hopping, channel management, and dual-mode architecture means standard Bluetooth implementations may be implicated. The without-prejudice dismissal means this risk has not been extinguished.
PatSnap Eureka’s FTO Search Agent can map each of the eight Bandspeed patent numbers against your product’s technical specification, identify claim elements that read on Bluetooth audio chipset features, and surface any post-grant review history that may have narrowed claim scope. For procurement teams evaluating ATS3015-based supply chains, Eureka can also identify whether third-party licensees have resolved exposure — helping you benchmark your risk posture before committing to a product architecture.

What this case signals for the Bluetooth audio IP landscape
Eight unadjudicated Bluetooth patents and a without-prejudice exit create persistent risk for wireless audio product makers and chipset integrators.
A pre-answer dismissal after 692 days suggests negotiation, not abandonment
When a plaintiff waits nearly two years before exercising a unilateral Rule 41 exit, the timeline is consistent with licensing negotiations running in parallel to litigation. Bluetooth audio competitors and OEM chipset customers should treat this as a possible signal of ongoing portfolio licensing activity rather than a concession on patent strength.
No invalidity ruling means all eight patents remain fully enforceable
Because MPOW never answered and no claim construction or IPR record was established in this case, Bandspeed’s eight Bluetooth patents carry no litigation-derived weakness. Any company using Bluetooth Classic or LE technology in consumer audio products — especially those integrating the ATS3015 chipset or similar architectures — faces undiminished infringement exposure.
Bandspeed v MPOW — key questions answered
Bandspeed, Inc. filed an eight-patent Bluetooth infringement action against MPOW Technology in the Western District of Texas on 19 May 2023. On 10 April 2025, Bandspeed voluntarily dismissed the case without prejudice under Rule 41(a)(1)(A)(i), before MPOW had filed any answer. No merits ruling, damages award, or invalidity finding was issued.
Bandspeed asserted eight U.S. patents: US7903608B2, US9379769B2, US7570614B2, US7477624B2, US7027418B2, US8542643B2, US8873500B2, and US9883520B2. These cover Bluetooth wireless communication technologies including adaptive frequency hopping, channel management, piconet coordination, and dual-mode Classic and LE architecture.
A dismissal without prejudice means Bandspeed’s infringement claims were withdrawn but not permanently extinguished. Bandspeed retains the legal right to refile the same claims against MPOW or assert the same eight patents against other defendants in a future action. None of the patents were invalidated or found unenforceable by this case.
The accused products included the MPOW MX3 True Wireless Earbuds, mpow-432 and mpow-480 wireless earbud lines, Bluetooth 5.0 mono and twin-mode earbuds, ANC true wireless earbuds, and products incorporating the ATS3015 Bluetooth chipset. Both Bluetooth Classic and Bluetooth LE product families were implicated.
The public record does not disclose Bandspeed’s reasons. The extended pre-answer timeline — nearly two years — is consistent with parallel licensing negotiations, strategic portfolio repositioning, or a decision to pursue other enforcement targets. The without-prejudice designation suggests Bandspeed preserved its options deliberately rather than conceding on patent validity or infringement.
