HyperQuery LLC v. Synology, Inc. — Dismissed With Prejudice After 169 Days
HyperQuery LLC filed a patent infringement suit against Synology, Inc. in the Eastern District of Texas, asserting US9529918B2 covering systems and methods for downloading applications via a communication network. The case closed after 169 days when HyperQuery voluntarily dismissed all claims with prejudice — permanently surrendering the right to re-file against Synology on this patent.
App-download patent assertion ends in permanent dismissal for HyperQuery
On April 17, 2025, HyperQuery LLC filed a patent infringement action against Synology, Inc. in the United States District Court for the Eastern District of Texas (Case No. 2:25-cv-00416). The sole patent asserted was US9529918B2, which covers systems and methods for downloading applications via a communication network — technology directly relevant to Synology’s NAS-based app ecosystem and DSM package centre infrastructure.
The case closed on October 3, 2025, when HyperQuery filed a Notice of Dismissal under Rule 41(a)(1)(A)(i), voluntarily dismissing all claims with prejudice. The court accepted and acknowledged the notice, formally dismissing every pending claim and cause of action with prejudice and denying all remaining relief requests as moot. A with-prejudice dismissal is the most final outcome short of a merits judgment — HyperQuery cannot reassert these claims against Synology on this patent in any future action.
At 169 days, the case resolved before significant motion practice or discovery would typically conclude, suggesting either an early commercial resolution, a licensing arrangement, or a strategic decision by HyperQuery to withdraw following an unfavourable case assessment. The public record does not disclose whether any consideration changed hands. The with-prejudice designation, chosen by the plaintiff rather than imposed by the court, is notably stronger than a simple voluntary withdrawal and may reflect negotiated terms.

Dismissed with prejudice: what the voluntary withdrawal means for both parties
Rule 41(a)(1)(A)(i): plaintiff-initiated dismissal, no court consent needed
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. HyperQuery invoked this rule but designated the dismissal as with prejudice — an unusual and significant choice that converts what would ordinarily be a no-strings exit into a permanent bar on re-litigation of these specific claims against Synology.
Rule 41(a)(1)(A)(i) voluntary dismissalWith prejudice bars re-filing — a materially stronger outcome than without prejudice
A dismissal without prejudice would allow HyperQuery to re-file the same infringement claims against Synology in the future. A dismissal with prejudice permanently extinguishes those claims — it carries res judicata effect, meaning the same cause of action cannot be relitigated. HyperQuery voluntarily accepted this stronger standard. The public record does not state whether any settlement consideration was exchanged, but the with-prejudice designation typically signals either a negotiated resolution or a definitive strategic withdrawal.
Res judicata effect — permanent barSynology achieves full closure: no liability, no ongoing exposure on US9529918B2
For Synology, the with-prejudice dismissal is the closest available outcome to a defendant win short of a merits judgment. HyperQuery cannot reassert US9529918B2 infringement claims against Synology in US federal courts. Synology’s DSM platform and app-download infrastructure are effectively cleared of this specific assertion. However, the patent itself remains in force, and third parties or a new assignee could theoretically assert it against Synology in different claim configurations or on different products.
No liability — patent still in forceUS9529918B2 remains live — other NAS and app-platform vendors retain exposure
Although Synology has resolved its exposure, US9529918B2 has not been invalidated or adjudicated on the merits. Competitors in the NAS, cloud storage, and app-distribution platform space — including vendors offering similar package-management or application-download systems — should treat this patent as an active assertion risk. HyperQuery’s pattern of filing in the Eastern District of Texas and targeting network-connected device ecosystems suggests continued enforcement activity is plausible.

Official order — verbatim text
The court’s order closely tracks HyperQuery’s own Notice of Dismissal, accepting the with-prejudice designation without modification. The phrasing ‘ACCEPTS AND ACKNOWLEDGES’ confirms judicial recognition rather than judicial imposition — the finality was plaintiff-elected. Denying all remaining relief as moot confirms no fee-shifting, sanctions, or counter-relief was pending or granted. For Synology, this order functions as a final judgment with preclusive effect on these claims.
US9529918B2 — Systems and methods for downloading applications via a network
US9529918B2 (application number US14/103500) covers systems and methods for downloading applications via a communication network. The patent sits at the intersection of networked device management and application distribution — technology foundational to any platform that delivers software packages or apps to connected hardware over the internet. Its claims are likely directed at client-server architectures that manage, authenticate, and execute remote application downloads on end-user devices or network-attached systems.
For the NAS and network storage sector, this patent is strategically significant. Synology’s DSM operating system includes a Package Center that allows users to download and install applications directly to their NAS device over a network — a workflow that sits squarely within the patent’s stated subject matter. Vendors offering similar app-store or package-management functionality for IoT devices, routers, or enterprise storage systems should assess whether their implementations fall within the claim scope before expanding product features in this area.
Should you run an FTO against US9529918B2?
Any company developing or acquiring systems that facilitate application downloads to networked devices — including NAS vendors, cloud appliance manufacturers, IoT platform operators, and enterprise software distribution providers — should treat US9529918B2 as an active FTO concern. The patent survived this litigation without invalidation or narrowing, and HyperQuery’s willingness to file in E.D. Texas against a major NAS vendor suggests it will continue to be enforced against similarly positioned defendants.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map product features against US9529918B2’s claim language in minutes, identify prior art that could support an IPR petition, and monitor for continuation or divisional patents filed from the same application family. Running this analysis before product launch or before entering a new distribution channel is materially lower cost than responding to an E.D. Texas complaint.

What this case signals for the NAS and app-distribution IP landscape
A with-prejudice exit in under six months raises key questions for any vendor operating app-download or package-management infrastructure.
E.D. Texas remains the preferred venue for NPE app-platform assertions
HyperQuery’s choice of the Eastern District of Texas for a NAS app-download patent suit is consistent with the district’s continued appeal to non-practising entities. Defendants in this space should ensure their litigation-readiness posture — including prior art analysis and claim mapping — is calibrated for E.D. Texas procedural timelines.
With-prejudice dismissals in NPE cases often signal a negotiated exit
When a plaintiff voluntarily selects with-prejudice dismissal under Rule 41(a)(1)(A)(i), it typically suggests the parties reached a resolution — whether a licence, a covenant not to sue, or a paid settlement. Defendants and their counsel should treat this outcome as a signal that early engagement and case assessment drove a commercially efficient result.
HyperQuery v Synology — key questions answered
The with-prejudice dismissal permanently bars HyperQuery from re-filing the same patent infringement claims against Synology based on US9529918B2. It carries res judicata effect, meaning Synology faces no future exposure from HyperQuery on these specific claims. However, the patent itself remains valid and could be asserted by HyperQuery or a future assignee against other defendants.
HyperQuery elected with-prejudice dismissal under Rule 41(a)(1)(A)(i), which is unusual because it forfeits the right to re-file. This typically signals a negotiated resolution — such as a licence or covenant not to sue — or a firm strategic decision to abandon the claim. The public record does not disclose whether any consideration was exchanged between the parties.
US9529918B2 covers systems and methods for downloading applications via a communication network. For NAS vendors, this is directly relevant to package management and app-store functionality — such as Synology’s DSM Package Center — where users download and install applications to a network-attached device over the internet. Vendors offering similar functionality should assess their exposure through an FTO analysis.
The case was filed in the United States District Court for the Eastern District of Texas (Case No. 2:25-cv-00416). E.D. Texas remains a popular venue for non-practising entity patent assertions due to its plaintiff-friendly procedural history and experienced patent litigation docket. Defendants sued there face specific local rules and scheduling orders that can accelerate cost exposure early in litigation.
No. The with-prejudice dismissal only bars HyperQuery from re-suing Synology. US9529918B2 remains an issued, in-force patent. Other vendors — including those offering networked app-download, package management, or software distribution platforms — retain full exposure to potential infringement assertions. The patent was not challenged on validity in this proceeding.
