Valtrus Innovations v. Cloudflare — Voluntary Dismissal Without Prejudice
Valtrus Innovations, a patent assertion entity holding legacy Hewlett-Packard IP, sued Cloudflare in the Northern District of California over two network security patents targeting Cloudflare’s SSE, SASE, and Zero Trust products. The case closed in 122 days via voluntary dismissal without prejudice — leaving the door open for refiling.
Network security PAE targets Cloudflare’s Zero Trust stack in early exit
Valtrus Innovations, Ltd. — a patent assertion entity widely understood to hold patents originally developed within Hewlett-Packard — filed suit against Cloudflare, Inc. on July 25, 2025 in the U.S. District Court for the Northern District of California. The complaint asserted infringement of US6816809B2 and US7930539B2 against Cloudflare’s Secure Service Edge (SSE), Secure Access Service Edge (SASE), application security and performance services, and network services including the Cloudflare One and Zero Trust product lines.
On November 24, 2025 — 122 days after filing — Valtrus filed a notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Cloudflare had not yet filed an answer or a motion for summary judgment, Valtrus was entitled to dismiss as of right, requiring no court order and producing no merits ruling. The case closed with no judgment, no injunction, and no fee award.
The 122-day lifespan and pre-answer exit is consistent with early-stage resolution dynamics — whether driven by settlement discussions, strategic repositioning, or venue or claim reassessment. The public record does not disclose any settlement terms. Critically, a dismissal without prejudice preserves Valtrus’s right to refile the same claims, subject to applicable statutes of limitation, meaning Cloudflare’s exposure on these two patents has not been fully extinguished.
Filing to Voluntary dismissal in 122 days
122 days — resolved before Cloudflare filed an answer
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no merits reached
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss a case without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because Cloudflare had not yet answered, Valtrus could exit unilaterally. No judge ruled on the merits of infringement or validity — the case simply ceased to exist as a live proceeding.
No merits adjudicationPublic record is silent on settlement — prejudice distinction matters
A dismissal without prejudice means the plaintiff retains the right to refile the same claims against the same defendant, subject to the relevant statute of limitations. A dismissal with prejudice would bar those claims permanently. The notice here expressly states ‘without prejudice.’ No settlement agreement or release of claims is disclosed in the public record, so it cannot be confirmed whether a private resolution accompanied the dismissal.
Refiling risk remainsNo win on the merits — and no permanent shield from these patents
Cloudflare avoided a merits judgment and incurred no adverse ruling on infringement or validity of US6816809B2 or US7930539B2. However, the without-prejudice nature of the dismissal means Cloudflare cannot treat this case as a definitive resolution. The patents remain valid and enforceable, and Valtrus or any future assignee retains the ability to reassert them — a risk that product and IP teams should continue to monitor.
Exposure not extinguishedSSE and Zero Trust vendors face ongoing PAE assertion risk
The assertion of legacy HP-lineage patents against Cloudflare’s Zero Trust and SSE stack reflects a broader PAE strategy of targeting high-growth network security categories. A without-prejudice exit preserves optionality for Valtrus and signals that other SSE, SASE, and Zero Trust platform providers should assess their exposure to this patent family. Companies building on similar network proxy, authentication, or traffic-inspection architectures should consider FTO analysis as a proactive step.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) explicitly, confirming the exit was a unilateral plaintiff right rather than a negotiated court order — a procedurally significant distinction. The absence of an answer from Cloudflare confirms the case ended before substantive litigation commenced. No claim construction, no invalidity briefing, and no infringement ruling appear on the docket. For Cloudflare, this means no estoppel benefit; for Valtrus, it means full freedom to reassert these claims in a future action.
US6816809B2 & US7930539B2 — network security and access control
US6816809B2 (application no. US10/200175) and US7930539B2 (application no. US10/910652) are utility patents in the network security domain, both originating from application filings in the early-to-mid 2000s and traceable to Hewlett-Packard’s enterprise networking and security research. Their assertion against Cloudflare’s SSE, SASE, and Zero Trust products suggests the claims are directed at methods or systems for network traffic inspection, access control, or security event processing at the network edge.
The strategic significance of these patents lies in their potential breadth across modern cloud-native security architectures. As Zero Trust Network Access (ZTNA) and SSE platforms have emerged as the dominant enterprise security paradigm, legacy patents covering underlying inspection, authentication, or proxy-layer techniques have become high-value enforcement assets. Any vendor offering identity-aware network proxying, inline threat inspection, or policy-based access controls — the core of products like Cloudflare One — should assess whether their implementation falls within the claim language of this patent family.
Should your team run an FTO against US6816809B2 and US7930539B2?
If your organisation develops or deploys SSE, SASE, Zero Trust access, or cloud-native network security services, this case is a direct signal to review your freedom to operate. Valtrus has demonstrated willingness to assert these patents against a major market participant. The without-prejudice dismissal means the risk has not been resolved — it has merely paused. Product teams building on network traffic inspection, policy enforcement points, or identity-based access architectures are the most directly exposed.
PatSnap Eureka’s FTO Search Agent can automatically map the claim language of US6816809B2 and US7930539B2 against your product’s technical architecture, identify relevant prior art that may support invalidity arguments, and flag related patents in the Valtrus portfolio that may pose additional risk. Run a targeted FTO analysis before Valtrus files its next complaint — proactive clearance is materially cheaper than defending a district court action.

What this case signals for the network security IP landscape
A pre-answer voluntary dismissal rarely ends the story. Here is what practitioners and product teams should take from this outcome.
Without-prejudice dismissals are not safe harbors — monitor closely
The case closed without any ruling on infringement or validity. Valtrus retains full legal standing to refile against Cloudflare or assert these patents against other defendants. Companies in the SSE, SASE, and Zero Trust space should treat this as an ongoing threat signal rather than a resolved dispute.
Pre-answer exit patterns often reflect early negotiation dynamics
Cases dismissed in under 122 days before an answer is filed are consistent with early demand-letter-style litigation tactics — filing suit to open negotiations rather than pursue full trial. Whether or not a private settlement was reached, the pattern suggests Valtrus is an active enforcer of this HP-derived portfolio and may target additional defendants.
Valtrus v Cloudflare — key questions answered
It means Valtrus voluntarily ended the case before Cloudflare answered, with no merits ruling. ‘Without prejudice’ means Valtrus retains the right to refile the same patent infringement claims against Cloudflare in the future, subject to the statute of limitations. No judgment, injunction, or fee award was entered.
Valtrus asserted two patents: US6816809B2 (application no. US10/200175) and US7930539B2 (application no. US10/910652). Both are in the network security domain and are widely understood to derive from Hewlett-Packard’s legacy patent portfolio. They were asserted against Cloudflare’s SSE, SASE, Zero Trust, and Cloudflare One products.
The public record does not disclose the reason. Common drivers of pre-answer voluntary dismissals include early settlement negotiations, strategic reassessment of claim strength, venue considerations, or a decision to refile in a different jurisdiction. The without-prejudice nature of the dismissal preserves all of Valtrus’s options for future action.
Not definitively. Cloudflare avoids an adverse merits ruling and incurs no liability in this action. However, a dismissal without prejudice does not invalidate the asserted patents or establish non-infringement. Cloudflare remains exposed to potential refiling by Valtrus or any future assignee of US6816809B2 and US7930539B2.
Valtrus Innovations is a patent assertion entity that holds a portfolio of patents widely understood to originate from Hewlett-Packard and related entities. It has been active in asserting enterprise technology patents — including networking, security, and infrastructure patents — against major technology companies. This case is consistent with a broader enforcement strategy targeting cloud-native network security vendors.
