Schneider Electric v. Ilumi: Socket & Switch Patent Appeal Denied
Schneider Electric Brasil Ltda challenged Ilumi Indústria e Comércio Ltda in an invalidity and cancellation action over utility model patent BRMU1310424U2, covering constructive arrangements applied to sets of sockets and switches. The Court of Justice of São Paulo denied the interlocutory appeal, leaving the lower-level disposition in place.
Brazilian utility model patent survives interlocutory challenge
Schneider Electric Brasil Ltda, a subsidiary of the global electrical equipment group, brought an invalidity and cancellation action against Ilumi Indústria e Comércio Ltda before Brazilian courts, targeting utility model patent BRMU1310424U2. That patent protects a constructive arrangement applied to a set of sockets and switches — a category of product central to the low-voltage electrical components market in Brazil. The dispute was adjudicated within the jurisdiction of the Court of Justice of São Paulo.
The case closed on 5 April 2025 when the Court of Justice of São Paulo denied the granting of the interlocutory appeal filed in the proceedings. The court’s ruling, framed as a denial of the agravo de instrumento (interlocutory appeal), means the procedural or substantive relief sought at that interim stage was refused. Because the dismissal is characterised as an appeal dismissal rather than a final merits judgment, the underlying invalidity/cancellation action’s ultimate fate depends on continued lower-court proceedings unless settled or withdrawn.
The absence of a filing date in the public record limits precise duration analysis, though the case closed in early April 2025. Interlocutory appeals of this type in Brazilian IP disputes are typically filed to challenge interim injunctions or procedural orders; denial suggests the appellate panel found insufficient grounds to override the lower court’s interim position. What remains unknown from the public record is whether the substantive invalidity claim against BRMU1310424U2 proceeds to final judgment.

Interlocutory appeal denied: what the ruling means for both parties
What a denied interlocutory appeal means in Brazilian IP proceedings
An interlocutory appeal (agravo de instrumento) in Brazilian civil procedure is a challenge to an interim ruling — such as a preliminary injunction or procedural order — rather than a final judgment. When the Court of Justice of São Paulo denies its granting, it confirms that the lower court’s interim position stands. This is a procedural outcome; it does not constitute a final merits ruling on the validity or cancellation of patent BRMU1310424U2.
Procedural dismissalIlumi retains interim position as BRMU1310424U2 remains uncancelled
As the holder of utility model BRMU1310424U2, Ilumi benefits from the denial of the interlocutory appeal. The patent’s enforceability is not disturbed at this stage, and any interim protection the lower court may have afforded continues. However, the underlying invalidity/cancellation action may still proceed, meaning Ilumi’s position is protected for now but not definitively resolved in its favour.
Patent survives this stageSchneider Electric’s interim challenge fails; main action continues
Schneider Electric Brasil’s denial at the interlocutory stage means the specific procedural or injunctive relief it sought through the appeal was refused. The company retains the ability to pursue the underlying invalidity and cancellation claim to a final merits decision at the lower court level. Strategically, this setback may inform litigation tactics and the grounds pursued in the substantive phase of proceedings.
Main action may continueSocket and switch IP enforcement remains active risk in Brazil
The dispute signals that utility model patents covering constructive arrangements in electrical socket and switch assemblies are being actively enforced and contested in Brazil. For competitors and new entrants in the low-voltage electrical components market, the case consistently suggests that design and engineering choices in this product category carry IP risk. Monitoring BRMU1310424U2 and related Brazilian utility models is prudent for product teams.

Official order — verbatim text
The court’s ruling — denying the granting of the interlocutory appeal — is a procedural disposition rather than a merits judgment on patent validity. In Brazilian civil procedure, such a denial confirms the appellate panel found no reversible error or sufficient urgency to override the lower court’s interim position. It does not extinguish the underlying invalidity/cancellation claim against BRMU1310424U2, which may still proceed. For Ilumi, the interim status quo is preserved; for Schneider Electric, the path to cancellation runs through the substantive lower-court proceedings.
BRMU1310424U2 — Constructive arrangement for socket and switch sets
BRMU1310424U2 is a Brazilian utility model (modelo de utilidade) protecting a constructive arrangement applied to a set of sockets and switches. Brazilian utility models cover three-dimensional forms applied to objects with industrial applicability and a functional improvement, and they typically enjoy a shorter prosecution timeline than invention patents. The specific constructive arrangement claimed suggests the patent focuses on the physical configuration and assembly of the socket-switch product, covering how components are structurally integrated rather than an underlying electrical method.
In the Brazilian low-voltage electrical components market — where product differentiation often turns on form factor, modularity, and ease of installation — utility model protection over a specific constructive arrangement can establish a meaningful competitive barrier. For Ilumi as a domestic manufacturer competing with multinationals such as Schneider Electric, holding this patent represents a credible enforcement asset. Competitors developing socket and switch product lines for the Brazilian market should assess whether their constructive arrangements fall within the claim scope of BRMU1310424U2.
Should your team run an FTO against BRMU1310424U2?
Any company designing, manufacturing, or importing socket and switch assemblies intended for the Brazilian market should treat BRMU1310424U2 as a live FTO risk. The patent has already attracted litigation from a major multinational, confirming it is being actively monitored and enforced. Product teams developing modular or integrated socket-switch configurations — particularly those with constructive arrangements similar to Ilumi’s registered design — are the most directly exposed and should commission an FTO assessment before market entry or product launch.

A major multinational’s failed interlocutory challenge highlights the procedural and substantive complexity of utility model enforcement in Brazil.
Utility model patents in Brazil are a credible enforcement tool
BRMU1310424U2 surviving an interlocutory challenge from a well-resourced multinational suggests Brazilian utility model patents covering physical product configurations carry real enforceability weight. Companies designing electrical socket and switch products for the Brazilian market should conduct FTO assessments against local utility model registrations, not just invention patents.
Interlocutory appeals in Brazilian IP cases carry strategic risk
Filing an agravo de instrumento is often used to disrupt interim injunctions or interim orders. Denial by the São Paulo Court of Justice indicates the appellate panel found the lower court’s position defensible. Litigants should assess the strength of interim rulings before committing to an interlocutory appeal strategy, as an unsuccessful challenge may signal the merits posture.
LTDA v ILUMI — key questions answered
The Court of Justice of São Paulo denied the granting of the interlocutory appeal on 5 April 2025. This is a procedural outcome — the appellate panel refused the interim relief sought, leaving the lower court’s position intact. The underlying invalidity and cancellation action targeting patent BRMU1310424U2 may continue in the lower court.
BRMU1310424U2 is a Brazilian utility model patent held by Ilumi Indústria e Comércio Ltda. It protects a constructive arrangement applied to a set of sockets and switches, covering the physical configuration and structural integration of these electrical components. Schneider Electric Brasil sought its invalidity and cancellation in this dispute.
In Brazilian civil procedure, an agravo de instrumento is an interlocutory appeal challenging an interim ruling — such as a preliminary injunction, evidence order, or procedural decision — rather than a final judgment. When denied, it means the appellate court found insufficient grounds to override the lower court’s interim position. It does not resolve the underlying merits of the case.
No. The denial is a procedural ruling only; it does not constitute a final determination on the validity of BRMU1310424U2. The appellate panel refused the specific interim relief Schneider Electric sought at this stage. The substantive invalidity and cancellation claim may still proceed before the lower court, where validity will ultimately be assessed on the merits.
Manufacturers, importers, and distributors of socket and switch assemblies in Brazil should treat BRMU1310424U2 as an active enforcement risk. The patent has been asserted in litigation against a major multinational, confirming it is being monitored. Companies with products featuring constructive arrangements similar to the Ilumi patent should conduct freedom-to-operate analysis before market entry or product update.
