Songbird Tech v. ASUSTek: Infringement Suit Dismissed With Prejudice in 89 Days
Songbird Tech, LLC brought a patent infringement action against ASUSTek Computer, Inc. in the Western District of Texas, asserting US8825787B2 against the Chromebook series and Zenbook Pro Duo UX581 products. Before ASUSTek filed any responsive pleading, Songbird voluntarily dismissed the case with prejudice — ending all claims permanently in just 89 days.
A rapid voluntary exit: Songbird Tech ends ASUSTek suit with finality
On March 7, 2024, Songbird Tech, LLC filed a patent infringement complaint against ASUSTek Computer, Inc. in the U.S. District Court for the Western District of Texas (Case No. 6:24-cv-00122), presided over by Judge Xavier Rodriguez. The asserted patent, US8825787B2 (application no. US13/898475), was alleged to be infringed by ASUSTek’s Chromebook series, Zenbook Pro Duo UX581 (Alexa), and Zenbook Pro Duo UX581 (Cortana) product lines.
On June 4, 2024 — just 89 days after filing — Songbird Tech filed a notice of voluntary dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because ASUSTek had not yet served an answer or motion for summary judgment, Songbird was entitled to dismiss unilaterally without a court order. The ‘with prejudice’ designation means Songbird Tech is permanently barred from re-asserting the same claims against ASUSTek on the same patent.
The sub-90-day timeline and the unusual choice to dismiss with prejudice — rather than without prejudice — suggests the parties likely reached a private resolution, potentially including a license or covenant not to sue, though the public record is silent on any settlement terms. Alternatively, Songbird may have identified a fatal weakness in its infringement position after filing. The dismissal with prejudice forecloses any future litigation on US8825787B2 against ASUSTek, making this a definitive, if quietly resolved, conclusion.

Dismissed with prejudice: what Songbird’s unilateral exit means for both parties
FRCP 41(a)(1)(A)(i): plaintiff’s right to exit without court approval
Under Rule 41(a)(1)(A)(i), a plaintiff may file a notice of dismissal as of right — requiring no court order — provided the opposing party has not yet served an answer or motion for summary judgment. ASUSTek had not done so here, giving Songbird unilateral power to end the case. Crucially, Songbird chose ‘with prejudice,’ converting what could have been a flexible exit into a permanent bar on re-filing the same claims.
Voluntary dismissal — with prejudiceSongbird permanently surrenders its infringement claims against ASUSTek
By dismissing with prejudice, Songbird Tech has relinquished any future right to assert US8825787B2 against ASUSTek on the accused Chromebook and Zenbook Pro Duo products. This is an unusually final outcome for a voluntary pre-answer dismissal. It typically signals either a negotiated resolution — such as a license or covenant not to sue — or a strategic concession after discovering a substantive weakness. The public record does not confirm which.
Claims extinguished — no re-filing permittedASUSTek exits without filing a single pleading — and wins permanent protection
ASUSTek never served an answer, motion to dismiss, or motion for summary judgment. Despite that, it obtains a with-prejudice dismissal — the strongest possible defense outcome short of a court judgment. ASUSTek is now fully insulated from any future suit by Songbird Tech on US8825787B2 for the accused product lines. Desmarais LLP’s handling suggests a hardline posture that may have influenced Songbird’s swift exit.
Full protection — no merits exposureOther ASUSTek product lines and third parties remain potentially exposed
The with-prejudice dismissal protects only ASUSTek on the specific accused products. US8825787B2 remains a live, enforceable patent that Songbird Tech may assert against other manufacturers of similar communication-enabled laptops and devices. Competitors in the Chromebook and smart-device ecosystem should treat this resolution as a signal — not an all-clear — and consider FTO analysis against US8825787B2 independently.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) with clinical precision, confirming ASUSTek’s pre-answer status and Songbird’s unilateral right to exit. The explicit ‘with prejudice’ election is the analytically significant choice: it converts a procedural off-ramp into a permanent merits bar. Courts treat such dismissals as res judicata on the dismissed claims. The absence of any fee or cost ruling, and the lack of any court order, confirms this was a self-executing plaintiff notice — not a stipulated or negotiated court filing.
US8825787B2 — device network communication technology
US8825787B2, filed under application number US13/898475, is the sole patent asserted in this action. The patent sits within the domain of network communication and device interaction — a technical area highly relevant to modern laptops and smart devices that integrate voice-assistant functionality and cross-device communication protocols. The application date context and grant history place it squarely in the era of expanding cloud-connected consumer device ecosystems.
The patent’s assertion against ASUSTek’s Chromebook series and Zenbook Pro Duo UX581 variants — products integrating Alexa and Cortana voice assistants — suggests the claims may read on communication or control interfaces between devices and cloud-based or assistant-driven services. For OEMs building connected laptops or smart devices with assistant integrations, US8825787B2 represents a monitoring priority. The patent remains enforceable and Songbird Tech’s dismissal of the ASUSTek suit does not limit future assertion against other defendants.
Should you run an FTO against US8825787B2?
Any OEM or ODM producing Chromebooks, Windows laptops with voice-assistant integration, or connected consumer devices should treat US8825787B2 as a live FTO concern. Songbird Tech’s willingness to file in W.D. Tex. and extract a with-prejudice exit — likely on licensing terms — signals active monetisation of this patent. Product teams designing or launching devices with cloud communication or voice-assistant control interfaces should assess whether their architecture intersects with the patent’s claim scope before go-to-market.

What this case signals for the laptop and smart-device IP landscape
A pre-answer dismissal with prejudice in W.D. Tex. is rare enough to reward closer scrutiny of both the patent and the parties’ likely off-record arrangements.
With-prejudice voluntary dismissals almost always signal off-record resolution
When a plaintiff dismisses with prejudice before the defendant even answers, it almost never reflects a change of heart. The permanent bar on re-filing strongly suggests a license, lump-sum payment, or covenant not to sue was negotiated in the 89-day window. IP teams monitoring Songbird Tech should flag this as a likely licensing event even without a public settlement record.
W.D. Tex. remains a favoured venue despite post-Waco transfer pressure
Songbird filed in the Western District of Texas — a forum that retains attractiveness for patent plaintiffs despite increased transfer scrutiny following In re Apple. The 89-day resolution suggests ASUSTek’s counsel (Desmarais LLP) may have pressed quickly on venue or merits vulnerability, accelerating Songbird’s decision to exit. Monitoring transfer motions filed in similar W.D. Tex. NPE suits can reveal early pressure patterns.
Songbird v Asustek — key questions answered
A with-prejudice dismissal under FRCP 41(a)(1)(A)(i) permanently bars Songbird Tech from re-asserting the same claims of US8825787B2 against ASUSTek Computer on the accused Chromebook and Zenbook Pro Duo products. The dismissal functions as res judicata. However, it does not prevent Songbird from asserting the patent against other defendants.
The public record does not disclose the reason. However, a with-prejudice voluntary dismissal at the pre-answer stage typically signals a negotiated resolution — such as a patent licence, lump-sum payment, or covenant not to sue — reached in the 89-day period between filing and dismissal. It may also reflect a strategic decision following assessment of claim vulnerability or an IPR threat from ASUSTek’s counsel.
The complaint identified three product lines: the Chromebook series, the Zenbook Pro Duo UX581 (Alexa), and the Zenbook Pro Duo UX581 (Cortana). The Alexa and Cortana variants suggest the asserted claims may relate to voice-assistant communication or device control interfaces, though the specific claim mapping is not detailed in the public record.
Yes. The with-prejudice dismissal extinguishes only Songbird Tech’s claims against ASUSTek. The patent itself remains in force and Songbird Tech retains the right to assert it against any other party. OEMs producing connected devices with voice-assistant or network communication functionality should treat US8825787B2 as an active enforcement risk.
Songbird Tech invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss an action without a court order by filing a notice of dismissal before the opposing party serves either an answer or a motion for summary judgment. ASUSTek had not served either, making the rule’s conditions satisfied. The notice was self-executing — no court approval was required.
