Portus Pty Ltd v. Schneider Pvt Ltd — Infringement Action Dismissed Without Prejudice After 836 Days
Australian IP holder Portus Pty Ltd brought a two-patent infringement action in Delaware against Schneider Pvt Ltd, targeting products including EVlink Charging, MultiSight, VideoXpert, and Wiser smart-home systems. After 836 days of litigation, the Delaware District Court closed the case with a dismissal without prejudice — leaving the door open for future re-filing.
Two-Patent Network Security Suit Against Schneider Ends Without Merits Ruling
On 5 September 2023, Portus Pty Ltd — an Australian IP holding entity — filed a patent infringement complaint against Schneider Pvt Ltd in the District of Delaware, asserting US8914526B1 and US9961097B2. The accused products spanned a broad range of Schneider commercial and consumer technology: EVlink EV-charging infrastructure, the Schneider/Pelco MultiSight and VideoXpert video management platforms, Wiser and Wiser Air smart-home devices, and associated IP camera systems.
The case closed on 19 December 2025 with a dismissal without prejudice — meaning the court entered no judgment on the merits of Portus’s infringement or validity claims. A without-prejudice dismissal leaves all substantive patent rights intact; Portus is not barred from asserting the same patents against Schneider or others in a future proceeding, subject to applicable statutes of limitations and any intervening patent expiry.
An 836-day lifespan without a merits decision is consistent with a negotiated resolution or a strategic decision by the plaintiff to withdraw ahead of a potentially adverse ruling — though the public record does not confirm which. The absence of a prejudice finding or fee award suggests the parties may have reached a private arrangement. What remains unknown is whether any licensing terms, covenant not to sue, or commercial agreement accompanied the dismissal.

Dismissed without prejudice: what the termination means for both parties
Dismissal without prejudice leaves claims legally alive
A dismissal without prejudice is a non-merits termination: the court enters no judgment on infringement, validity, or damages. Portus’s patents are not invalidated, and no claim preclusion attaches. The practical effect is that the litigation clock resets — Portus could re-file the same claims in the same or a different forum, provided the patents remain in force and any applicable limitations period has not expired.
No merits adjudicationPortus preserves patent rights but gains no enforcement win
The without-prejudice dismissal means Portus obtained no damages award, injunction, or royalty judgment from this proceeding. However, it retains the full right to enforce US8914526B1 and US9961097B2 against Schneider or third parties in the future. If a private settlement accompanied the dismissal, Portus may have achieved its commercial objective — but the public record is silent on any licensing or payment terms.
Re-filing right preservedSchneider exits without an invalidity ruling or fee award
Schneider avoids a liability finding and any damages exposure from this proceeding. Critically, no court has declared either asserted patent invalid or unenforceable, so Schneider’s EVlink, MultiSight, VideoXpert, and Wiser product lines remain exposed to future assertion. The absence of a fee award under 35 U.S.C. § 285 suggests the case was not characterised as exceptional — a neutral outcome from Schneider’s perspective.
No invalidity ruling obtainedPatent cloud remains over EV charging and video surveillance tech
Because neither patent was invalidated or adjudicated, competitors and licensees in the EV-charging infrastructure, IP camera, and smart-building control sectors should treat both patents as fully enforceable. The broad product scope alleged — spanning EV chargers, video management systems, and IoT home devices — suggests these patents may have relevance beyond Schneider. Companies in adjacent technology categories should consider FTO analysis before expanding into the asserted claim space.

Official order — verbatim text
The dismissal without prejudice closes the docket without resolving any substantive dispute between the parties. This phrasing is legally significant: it is not a consent judgment, a stipulated dismissal with prejudice, or a court-ordered invalidity ruling. The infringement allegations against EVlink, MultiSight, VideoXpert, and Wiser products are unresolved. Both US8914526B1 and US9961097B2 retain their full presumption of validity under 35 U.S.C. § 282, and Schneider has obtained no estoppel or preclusion benefit from this termination.
US8914526B1 & US9961097B2 — Network Security and Video Surveillance System Patents
US8914526B1 (Application No. US09/868417) and US9961097B2 (Application No. US14/536784) together cover network-connected device management and video surveillance architectures. The breadth of accused products — ranging from EV-charging infrastructure to IP camera platforms and smart-home controllers — indicates the claims likely address underlying communication and authentication protocols rather than product-specific hardware implementations, making them relevant across multiple connected-device verticals.
The strategic significance of these patents lies in their potential application to any networked device management platform in the smart-building, industrial IoT, or physical security space. Portus’s assertion against Schneider — one of the largest building-technology companies globally — demonstrates that the claims are considered viable against enterprise-grade infrastructure. For competitors developing converged building management or EV-fleet charging management systems, these patents represent active enforcement risk that should be factored into IP strategy.
Should you run an FTO analysis against US8914526B1 and US9961097B2?
Any R&D or product team developing network-connected device management systems, IP camera platforms, video management software, EV-charging controllers, or smart-building IoT hubs should prioritise FTO assessment against these two patents. The fact that Portus asserted both patents against five distinct Schneider product lines — spanning industrial, commercial, and consumer categories — suggests claim language broad enough to capture a wide range of networked architectures.
PatSnap Eureka’s FTO Search Agent can map your product’s technical architecture against the claim trees of US8914526B1 and US9961097B2, identifying potential design-around opportunities and prosecution history estoppel that may limit their enforceability. With both patents currently active and unlitigated to a merits decision, early FTO work is materially lower cost than responding to a demand letter or defending a re-filed complaint in Delaware.

What this case signals for the smart-building and video surveillance IP landscape
A without-prejudice dismissal after 836 days typically signals private resolution — but the patent risk does not disappear with the docket entry.
Without-prejudice dismissals do not extinguish patent enforcement risk
Companies that see a competitor’s lawsuit dismissed without prejudice should not treat the event as IP clearance. Both US8914526B1 and US9961097B2 remain in force. Any product team working on EV-charging management, video surveillance platforms, or smart-home connectivity should conduct or refresh FTO analysis against these patents before new product launches.
Broad accused product scope signals patents with wide claim coverage
Portus alleged infringement across five distinct product lines — EV charging, multi-camera management, video analytics, and IoT control — suggesting the asserted claims are drafted broadly enough to cover network-connected device management at a systemic level. Companies developing converged IoT or building-management platforms should map their architectures against these claims as a priority.
Portus v Schneider — key questions answered
The case was dismissed without prejudice on 19 December 2025 in the District of Delaware. No merits ruling was issued on infringement or validity of the two asserted patents, US8914526B1 and US9961097B2. Portus retains the right to re-file its claims.
Portus asserted US8914526B1 (Application No. US09/868417) and US9961097B2 (Application No. US14/536784), covering network security and video surveillance system technologies, against Schneider’s EVlink Charging, MultiSight, VideoXpert, Wiser and Wiser Air products, and related video management and IP camera devices.
A dismissal without prejudice means no judgment was entered on the merits. Portus’s patents are not invalidated and no claim preclusion prevents re-filing. Portus could assert US8914526B1 or US9961097B2 again against Schneider or other parties in a new action, subject to patent expiry and any applicable statute of limitations.
The accused products included EVlink Charging (EV infrastructure), Schneider/Pelco MultiSight and VideoXpert (video management platforms), Wiser and Wiser Air (smart-home and building control systems), and associated video management systems and IP camera devices.
The case ran for 836 days from filing (5 September 2023) to closure (19 December 2025) — above the median for D. Del. patent cases resolved without trial. This duration is consistent with active claim construction proceedings, contested discovery, or extended settlement negotiations. The without-prejudice outcome suggests the parties may have reached a private arrangement before trial.
