Fortinet v. Netskope (25-1085): Federal Circuit Appeal Voluntarily Dismissed
Fortinet, Inc. brought a patentability challenge against Netskope at the Federal Circuit over US9280678B2, a patent covering secure cloud storage distribution and aggregation technology. The appeal was voluntarily dismissed just 16 days after filing, with no merits ruling issued by the court.
A 16-day Federal Circuit appeal that never reached the merits
On 22 October 2024, Fortinet, Inc.—represented by Quinn Emanuel Urquhart & Sullivan, LLP—filed an appeal at the Court of Appeals for the Federal Circuit (Case No. 25-1085) challenging the patentability of US9280678B2. The patent, filed under application number US14/094484, covers secure cloud storage distribution and aggregation, a technology domain central to cloud-native security platforms. Netskope, a leading cloud security provider, was named as the respondent, with Perkins Coie LLP leading its defence.
The proceedings were brought to a close on 7 November 2024—just 16 days after filing—when the appeal was voluntarily dismissed. The public record does not specify whether the dismissal was with or without prejudice, leaving the precise legal effect on Fortinet’s ability to re-litigate the same patentability questions formally unresolved from the available docket data. No merits ruling was issued, meaning the Federal Circuit made no determination on the validity or enforceability of US9280678B2.
A 16-day lifespan is exceptionally brief even by the standards of short-lived Federal Circuit appeals, suggesting the parties may have reached a commercial or procedural agreement very shortly after the notice of appeal was filed. What prompted the original filing—and what drove its near-immediate withdrawal—remains undisclosed on the public record. For IP practitioners monitoring cloud security patent disputes, the absence of a merits ruling means the underlying validity questions on US9280678B2 remain legally unresolved.
Filing to Voluntary dismissal in 16 days
16 days — exceptionally short Federal Circuit appeal lifespan, suggesting a resolution reached immediately post-filing
Voluntarily dismissed: what the Federal Circuit closure means for both parties
Voluntary dismissal ends the appeal without any merits ruling
A voluntary dismissal at the Federal Circuit means Fortinet withdrew the appeal before any substantive judicial review occurred. The court issued no opinion on the patentability of US9280678B2. Because the basis of termination does not specify whether the dismissal was with or without prejudice, the formal legal effect—particularly whether Fortinet is barred from re-raising the same invalidity arguments—cannot be determined from the public docket alone.
No merits adjudicatedWith or without prejudice? The public record is silent
A dismissal ‘with prejudice’ bars the dismissing party from re-filing the same claim; ‘without prejudice’ preserves that right. This distinction carries significant strategic weight in patent validity disputes. The docket for Case No. 25-1085 records only ‘Voluntary dismissal’ without specifying either qualifier. Until further court documents are published or the parties disclose terms, practitioners should treat the scope of any preclusion as legally uncertain.
Prejudice status unconfirmedFortinet retreats without a Federal Circuit validity ruling in its favour
By voluntarily dismissing, Fortinet obtained no judicial finding that US9280678B2 is invalid or unpatentable. Any leverage the appeal might have created in parallel licensing or enforcement proceedings is extinguished at this level. Depending on the undisclosed terms, Fortinet may have resolved the underlying dispute commercially, or may retain the option to challenge the patent through alternative post-grant routes such as inter partes review.
No invalidity finding securedNetskope’s cloud storage patent survives the Federal Circuit challenge intact
With no merits ruling issued, US9280678B2 remains presumptively valid and enforceable. Netskope’s position is not formally strengthened by a judicial finding—since no court ruled in its favour—but the patent exits this proceeding without any adverse validity determination. Competitors and potential licensees in the secure cloud storage and SASE space should note that the patent’s enforceability is unchanged by this dismissal.

Official order — verbatim text
The Federal Circuit’s order records only that ‘The proceedings are DISMISSED’ on the basis of voluntary dismissal. This phrasing confirms a procedural termination rather than any substantive adjudication of patentability. No standard of review was applied—the court never assessed the merits. The absence of a with/without prejudice designation in the public docket leaves the preclusive effect formally ambiguous, a distinction that may matter considerably should either party seek to revisit the validity of US9280678B2 in future proceedings.
US9280678B2 — Secure Cloud Storage Distribution and Aggregation
US9280678B2 (application US14/094484) covers secure cloud storage distribution and aggregation—technology that underpins how enterprise data is distributed, stored, and accessed across multiple cloud environments with security controls applied at the aggregation layer. This is a core architectural component of modern cloud-native security stacks, including zero-trust and SASE deployments. The patent’s claims in this context were challenged on patentability grounds, suggesting the dispute centred on novelty or obviousness relative to prior art in the cloud security space.
In the competitive landscape of cloud security, patents covering storage distribution and aggregation architectures carry strategic significance. Fortinet and Netskope are direct competitors in the SASE and cloud security gateway markets, making US9280678B2 a potentially high-value asset for licensing leverage or exclusionary enforcement. The patent’s survival without a validity ruling means it remains available to Netskope—or any successor or assignee—as an active tool in future competitive disputes or licensing negotiations across the sector.
Should your product team run an FTO against US9280678B2?
Any organisation developing or commercialising secure cloud storage aggregation, cloud-native data distribution, or multi-cloud security gateway technology should assess its exposure to US9280678B2. The patent emerged intact from a Federal Circuit patentability challenge without a single merits ruling—meaning its claims have not been judicially narrowed or invalidated. R&D teams building SASE platforms, cloud access security brokers (CASBs), or zero-trust network access (ZTNA) products are most directly in scope.

What this case signals for the cloud security patent landscape
A near-instant Federal Circuit dismissal in a cloud security patentability dispute warrants close attention from IP teams across the SASE and zero-trust sectors.
Rapid voluntary dismissals often signal undisclosed deal activity
When a Federal Circuit appeal is withdrawn within 16 days of filing, it typically suggests that parties reached a commercial resolution—licensing, cross-licensing, or settlement—very shortly after the appeal was lodged. IP teams monitoring Fortinet and Netskope should watch for downstream licensing announcements or partnership changes in the secure cloud access space.
US9280678B2 remains a live enforcement risk for cloud storage competitors
No invalidity finding was issued in this proceeding. Organisations building or distributing secure cloud storage aggregation technology should treat US9280678B2 as an active enforcement asset. A freedom-to-operate analysis against this patent remains advisable for product teams developing cloud-native security or SASE platforms.
Fortinet v Netskope — key questions answered
Fortinet filed an appeal at the Court of Appeals for the Federal Circuit on 22 October 2024 challenging the patentability of US9280678B2, a patent held in connection with Netskope covering secure cloud storage distribution and aggregation. The appeal was voluntarily dismissed just 16 days later on 7 November 2024, with no merits ruling issued.
The public docket records only ‘Voluntary dismissal’ as the basis of termination, without specifying whether it was with or without prejudice. This distinction—which determines whether Fortinet can re-raise the same patentability arguments—remains unresolved from the available public record. Practitioners should treat the preclusive effect as legally uncertain absent further disclosure.
Yes. Because the Federal Circuit dismissed the appeal without reaching the merits, no invalidity or unpatentability finding was issued. US9280678B2 exits the proceeding presumptively valid and enforceable. Competitors in the secure cloud storage and SASE space should not assume the patent’s enforceability has been diminished by this case.
A voluntary dismissal ends the appellate proceedings at the request of the appellant—here, Fortinet—before the court rules on the substance of the patentability challenge. No opinion is issued, no claim construction is performed, and no validity determination is made. The practical effect depends on whether the dismissal is with or without prejudice, and on any undisclosed settlement or licensing terms between the parties.
Fortinet was represented by Quinn Emanuel Urquhart & Sullivan, LLP, with James M. Glass listed as counsel. Netskope was represented by Perkins Coie LLP, with Andrew Dufresne, Andrew Klein, Kyle R. Canavera, and Thomas N. Millikan listed as counsel on the defendant side.
