HyperQuery LLC v. ASUSTOR Inc: Infringement Case Dismissed With Prejudice
HyperQuery LLC filed suit against ASUSTOR Inc in the Eastern District of Texas, asserting US9529918B2 covering systems and methods for downloading applications via a communication network. The case closed after 145 days when HyperQuery voluntarily dismissed all claims with prejudice under Rule 41(a)(1)(A)(i), with each party bearing its own costs.
NPE Exits Early: HyperQuery Drops ASUSTOR App-Download Suit With Prejudice
On 15 January 2025, HyperQuery LLC — a non-practising entity represented by Rabicoff Law LLC — filed a patent infringement action against ASUSTOR Inc in the Eastern District of Texas (Case No. 2:25-cv-00036), asserting US9529918B2. The patent covers systems and methods for downloading applications via a communication network, a technology area directly relevant to ASUSTOR’s network-attached storage products that feature app-centre functionality.
The case closed on 9 June 2025 when HyperQuery filed a Notice of Voluntary Dismissal With Prejudice under Rule 41(a)(1)(A)(i). Because ASUSTOR had not yet answered the complaint or moved for summary judgment, the unilateral dismissal was available to plaintiff as of right. The court accepted and acknowledged the dismissal, formally extinguishing all of HyperQuery’s claims against ASUSTOR. Crucially, the with-prejudice designation means HyperQuery is permanently barred from asserting the same claims against ASUSTOR on this patent.
Resolution in 145 days — before any substantive litigation activity by the defendant — is consistent with a negotiated exit or a decision not to proceed on the merits. The public record does not disclose whether any settlement or licence was reached; the court’s cost order (each party bears its own) neither confirms nor refutes a private financial arrangement. The fact that a Lead Case in this consolidated series remains open suggests HyperQuery continues to pursue related actions against other defendants.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Under Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure, a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. HyperQuery exercised this right, triggering an automatic dismissal. The court’s role was limited to accepting and acknowledging the notice — no judicial merits determination was made.
No merits adjudicatedWith prejudice: HyperQuery’s claims against ASUSTOR are permanently extinguished
A dismissal with prejudice operates as a final judgment on the merits for res judicata purposes. HyperQuery cannot re-file the same patent claims against ASUSTOR on US9529918B2. This is more protective for ASUSTOR than a without-prejudice dismissal would be. The public record does not disclose the reason HyperQuery chose the more restrictive designation, though it is consistent with a private settlement or licensing resolution.
ASUSTOR permanently protectedHyperQuery retains the patent but loses enforcement rights against ASUSTOR
US9529918B2 remains in force and HyperQuery retains the right to assert it against other parties — as evidenced by the Lead Case remaining open. However, HyperQuery has permanently foreclosed any future claim against ASUSTOR on this patent. The mutual cost-bearing order means HyperQuery incurred its own litigation costs without any court-awarded recovery from this defendant.
Patent intact; ASUSTOR carved outASUSTOR gains permanent certainty; sector watches consolidated series
ASUSTOR exits with full legal certainty: no outstanding claim, no damages exposure, and a with-prejudice bar against re-litigation. For other NAS vendors or app-platform providers who may be named in HyperQuery’s consolidated Lead Case, this resolution offers limited precedent — no claim construction or validity ruling was issued. The outcome suggests early engagement with HyperQuery may be an effective strategy for similarly-situated defendants.

Official order — verbatim text
The court’s order accepts HyperQuery’s Rule 41(a)(1)(A)(i) notice without any substantive engagement — no claim construction, no validity ruling, no damages assessment. The with-prejudice designation is plaintiff-elected and permanent: ASUSTOR is fully insulated from future assertion of these specific claims. The denial of all other pending relief as moot confirms no ancillary motions survived the dismissal. The order’s reference to the Lead Case remaining open is the most commercially significant signal in the text.
US9529918B2 — System and Methods for Downloading Applications via Network
US9529918B2, filed under application number US14/103500, covers systems and methods for delivering downloadable applications to end-user devices via a communication network. The patent sits at the intersection of remote software distribution and session/network management — technology that underpins app-centre features in network-attached storage devices, smart TVs, routers, and other connected platforms. The granted claims define a structured process for how application packages are identified, requested, and transferred across a network.
For NAS vendors specifically, app-centre functionality is a competitive differentiator: platforms like ASUSTOR’s ADM, Synology’s Package Center, and QNAP’s App Center all deliver third-party applications over a network to the device. Any product line where the firmware manages remote application downloads could fall within the scope of US9529918B2’s claims. The fact that HyperQuery has filed a consolidated series of actions — not just a single-defendant suit — suggests the patent holder views the claim scope as broadly applicable across the NAS and networked device market.
Should your NAS or app-platform product be cleared against US9529918B2?
R&D and product teams building app-centre, package-management, or over-the-network software delivery features for NAS, routers, or embedded platforms should assess exposure to US9529918B2. HyperQuery’s consolidated enforcement campaign — with the Lead Case still open — means the risk is active and ongoing. An FTO analysis focused on the independent claims, particularly the network session and download-handshake steps, is the starting point for any credible risk assessment.

Pre-answer dismissals in E.D. Texas NPE cases often reflect private resolution
When an NPE voluntarily dismisses with prejudice before the defendant has answered, it typically signals a negotiated outcome — whether a licence, a covenant not to sue, or a walk-away. The mutual cost order neither confirms nor denies payment. Companies served with similar demand letters should treat early engagement as a viable path to full legal certainty.
The Lead Case staying open signals a multi-defendant campaign
The court’s direction to maintain the Lead Case as open confirms HyperQuery is pursuing a series of consolidated actions. App-platform or NAS vendors who have not yet been named should monitor US9529918B2 enforcement activity and assess their exposure to the claimed download-via-network methodology before receiving a complaint.
HyperQuery v ASUSTOR — key questions answered
A dismissal with prejudice operates as a final judgment on the merits for res judicata purposes. ASUSTOR is permanently protected from any future assertion by HyperQuery of the same claims under US9529918B2. The court accepted the plaintiff’s voluntary notice; no merits ruling was issued.
The public record does not disclose a settlement. The court’s dismissal order is silent on any private financial arrangement. The mutual cost-bearing instruction — each party bears its own fees — neither confirms nor refutes a licence or payment. The with-prejudice designation is consistent with a private resolution but is not conclusive evidence of one.
US9529918B2 covers systems and methods for downloading applications via a communication network. It was asserted against ASUSTOR, whose NAS products feature an app-centre that delivers third-party applications over a network to the device. HyperQuery alleged that this functionality infringed the patent’s claims.
Yes. The dismissal order expressly notes that the Lead Case in HyperQuery’s consolidated series remains open. The ASUSTOR case was one member case in a broader campaign. Other defendants in the consolidated docket continue to face active litigation on US9529918B2.
Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure permits a plaintiff to dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. Because ASUSTOR had not yet answered or moved for summary judgment, HyperQuery was entitled to dismiss unilaterally. The court had no discretion to reject the dismissal but formally accepted and acknowledged the notice.
