DataCloud Technologies v. SonicWall: Five-Patent Infringement Suit Dismissed With Prejudice
DataCloud Technologies, LLC filed suit against SonicWALL, Inc. in Delaware District Court asserting five network security patents against SonicWall firewalls, virtual appliances, and management software. The parties jointly stipulated to dismiss all claims with prejudice in just 129 days — each side bearing its own costs.
Five-Patent Network Security Suit Ends in Rapid Bilateral Dismissal
On 26 August 2024, DataCloud Technologies, LLC filed a patent infringement action against SonicWALL, Inc. in the District of Delaware before Judge Gregory B. Williams. DataCloud asserted five United States patents — US7209959B1, US8370457B2, US6651063B1, US6560613B1, and US7398298B2 — against a broad range of SonicWall products including its Android app, NS Series virtual appliances for KVM, Network Security Firewalls, multi-domain hosting infrastructure, and the SonicWall Network Security Manager’s user roles configuration.
The case closed on 2 January 2025 via a Fed. R. Civ. P. 41(a)(1)(A)(ii) stipulation of dismissal with prejudice, filed jointly by both parties through counsel. Dismissal with prejudice is a final adjudication on the merits under res judicata principles — DataCloud is permanently barred from reasserting these specific claims against SonicWall. Notably, the parties agreed that each side bears its own attorney fees, costs, and expenses, signalling a negotiated exit rather than a clear win for either side.
At 129 days, the resolution is strikingly fast for a five-patent Delaware case. This pace, combined with the mutual cost-bearing structure, is consistent with a confidential settlement or licensing arrangement reached before meaningful litigation expenditure — though the public record is silent on any financial terms. The absence of any court-ordered fee award also suggests neither party successfully pressed an exceptional-case argument under 35 U.S.C. § 285.

Dismissed with prejudice by stipulation: what this means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice explained
A dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires signatures from all parties and their counsel. When filed ‘with prejudice,’ it operates as a final judgment on the merits. DataCloud cannot refile the same patent claims against SonicWall in any court. This is the most permanent form of voluntary exit available — stronger than a without-prejudice dismissal and functionally equivalent to a defendant win on res judicata grounds.
Permanent bar on re-filingDataCloud permanently waives the right to re-sue SonicWall on these patents
By stipulating to dismissal with prejudice, DataCloud Technologies surrendered its ability to reassert US7209959B1, US8370457B2, US6651063B1, US6560613B1, and US7398298B2 against SonicWall. This outcome is consistent with a licensing resolution — patent assertion entities often accept with-prejudice dismissals once a royalty arrangement is reached — but the public record contains no confirmation of any payment or licence.
Claims extinguished vs. SonicWallSonicWall secures permanent dismissal without a fee award
SonicWall exits the litigation with all five patent claims dismissed with prejudice and no adverse cost order. The mutual cost-bearing structure means it absorbed its own legal spend without recovery. SonicWall did not obtain an invalidity ruling or a finding of non-infringement, leaving the patents themselves intact and enforceable against third parties. Any private licence terms negotiated remain confidential.
No invalidity ruling securedFive DataCloud patents remain live threats for other network security vendors
Dismissal with prejudice resolves only the DataCloud-SonicWall dispute. The five asserted patents — covering areas including virtual appliance networking, multi-domain infrastructure, and user-role management — remain in force and could be asserted against other firewall, VPN, or network management vendors. Competitors operating similar product lines should assess their exposure, particularly given DataCloud’s apparent willingness to litigate in Delaware.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), requiring consent of all parties, and expressly specifies dismissal ‘with prejudice’ — language that forecloses any future DataCloud action against SonicWall on these five patents. The equal cost-bearing provision is notable: it suggests neither party extracted a cost concession, which is consistent with a commercially balanced exit. The absence of any carve-out or reservation of rights language in the public filing indicates a clean, comprehensive resolution of all asserted claims.
US7209959B1 and four further DataCloud network security patents
The five asserted patents span application filing dates from approximately 2000 to 2007, placing their priority in the foundational era of enterprise internet infrastructure. US6651063B1 and US6560613B1 — the earliest — relate to internet domain and hosting management. US7209959B1 and US8370457B2 address network data management and virtual appliance communication. US7398298B2 targets user-role configuration with notification, directly implicated in SonicWall’s Network Security Manager product.
This portfolio’s breadth — spanning firewall appliances, Android mobile clients, KVM virtualisation, domain hosting, and cloud-based security management — is strategically significant. It suggests DataCloud (or its predecessors) accumulated patents across the full stack of enterprise network security. For vendors building SASE, SD-WAN, or cloud-managed firewall platforms, any of these five patents may read on modern architectures that evolved from the infrastructure these claims originally described.
Should your team run an FTO against US7209959B1 and the DataCloud portfolio?
Any organisation developing or commercialising network security appliances, virtual firewall instances, multi-tenant domain management, or cloud-based security management consoles should assess exposure to the DataCloud portfolio. The fact that DataCloud successfully brought SonicWall — a major cybersecurity vendor — to a with-prejudice settlement without producing a single invalidity ruling means these patents carry demonstrated assertion credibility.
PatSnap Eureka’s FTO Search Agent can map claim language from all five DataCloud patents against your product’s technical architecture, flag relevant prior art for each claim family, and identify whether continuation applications or related patents extend the risk horizon. Given the portfolio’s breadth across networking layers, a targeted multi-patent FTO is more efficient than sequential single-patent review.

What this case signals for the network security IP landscape
A five-patent filing resolved in under five months points to calculated assertion strategy — and residual risk for the broader firewall and network management sector.
Rapid dismissal in multi-patent cases often signals a licensing deal
When a plaintiff asserts five patents and then jointly stipulates to with-prejudice dismissal in 129 days — before any substantive motions — the pattern is consistent with a negotiated licence or covenant not to sue. Network security vendors facing similar DataCloud assertions should treat this timeline as a benchmark for resolution speed.
Delaware remains the venue of choice for NPE network security assertions
DataCloud chose Delaware District Court, consistent with broader NPE filing trends favouring its predictable case management and patent-experienced bench. Vendors in the firewall, virtual appliance, and network management space should monitor Delaware dockets for DataCloud or related-entity filings as a standard threat-intelligence practice.
DataCloud v SonicWALL — key questions answered
DataCloud Technologies filed a five-patent infringement suit against SonicWALL, Inc. in the District of Delaware on 26 August 2024. The case was dismissed with prejudice by joint stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) on 2 January 2025, with each party bearing its own costs. No validity or infringement rulings were issued.
DataCloud asserted five patents: US7209959B1, US8370457B2, US6651063B1, US6560613B1, and US7398298B2. These cover network data management, virtual appliance communications, internet domain hosting infrastructure, multi-domain web systems, and user-role configuration with notification in network security management platforms.
Dismissal with prejudice is a final adjudication under res judicata principles. DataCloud is permanently barred from re-asserting the same claims against SonicWall in any court. SonicWall secures a clean exit but received no invalidity ruling, meaning the patents remain enforceable against other defendants.
The accused products included the SonicWall Android app, SonicWall NS Series virtual appliances for KVM, SonicWall Network Security Firewalls, SonicWall systems for supporting multiple domain names on shared web infrastructure, and user roles configuration features in the SonicWall Network Security Manager.
Yes. The dismissal with prejudice resolves only the dispute between DataCloud and SonicWall. All five patents — US7209959B1, US8370457B2, US6651063B1, US6560613B1, and US7398298B2 — remain in force and could be asserted against other network security vendors. No invalidity or unenforceability finding was made by the court.
