Leroy Merlin v. Fabinject: São Paulo Court Grants Appeal, Dismissing Punitive Fine
Leroy Merlin Companhia Brasileira de Bricolagem successfully appealed before the Court of Justice of São Paulo against enforcement of a punitive fine sought by Fabinject Indústria Plástica Ltda. The dispute centres on Brazilian utility model patent BRMU8902584U2 covering a modular awning arrangement. The appellate court granted the appeal, extinguishing the fine claim as of 14 April 2025.
São Paulo Appeal Extinguishes Punitive Fine in Modular Awning Dispute
This case, registered as No. 2060984-42.2025.8.26.0000 before the Court of Justice of São Paulo, pits retail home improvement giant Leroy Merlin Companhia Brasileira de Bricolagem against Fabinject Indústria Plástica Ltda, a Brazilian plastics manufacturer. The underlying subject matter is Brazilian utility model patent BRMU8902584U2, which protects an arrangement for a modular awning — a product category directly relevant to Leroy Merlin’s retail and private-label operations in the Brazilian home improvement market.
Fabinject, as the aggrieved party, sought enforcement of a punitive fine against Leroy Merlin in the proceedings below. Leroy Merlin appealed that enforcement, and on 14 April 2025 the Court of Justice of São Paulo granted the appeal in full, dismissing the punitive fine. The court’s ruling — granting the appeal ‘in order to dismiss the enforcement of the punitive fine sought by the aggravated party’ — suggests the appellate panel found the fine legally unsustainable on procedural or substantive grounds, though the detailed rationale is not fully disclosed in the public record.
The resolution at the appellate level without a merits ruling on the underlying patent validity or infringement question leaves the core IP dispute potentially unresolved. The speed of the appellate decision — closed in April 2025 — suggests a relatively focused procedural challenge rather than a full re-litigation of the patent merits. What remains unclear from the public record is whether the underlying enforcement action or any infringement claim between the parties continues in a separate proceeding.

São Paulo Court grants appeal: what the ruling means for both parties
Appeal granted: punitive fine enforcement dismissed
When an appellate court grants an appeal to dismiss enforcement of a punitive fine, it does not necessarily rule on the merits of the underlying patent dispute. The court found grounds — procedural or substantive — to hold that the fine sought by Fabinject could not be enforced. This leaves the patent’s validity and any infringement question legally distinct from the fine ruling.
Procedural reversalLeroy Merlin avoids punitive fine exposure
Leroy Merlin’s successful appeal eliminates the immediate financial risk posed by the punitive fine. This is a commercially significant win for the retailer: punitive fines in Brazilian IP enforcement proceedings can be substantial. However, the outcome does not necessarily confirm that Leroy Merlin’s conduct with respect to patent BRMU8902584U2 was lawful — that question may remain open.
Fine liability extinguishedFabinject loses its fine claim on appeal
Fabinject, as the party that sought the punitive fine, sees that enforcement avenue closed by the appellate ruling. The patent holder may need to pursue alternative legal strategies to seek compensation or injunctive relief if it believes Leroy Merlin has infringed BRMU8902584U2. The public record does not indicate whether a separate infringement or validity proceeding is ongoing.
Fine claim dismissedModular awning IP enforcement risk recalibrated
This ruling suggests Brazilian courts will scrutinise the procedural basis for punitive fine enforcement in patent-related disputes. For retailers and manufacturers operating in the modular awning and home improvement accessories sector in Brazil, the case highlights the importance of challenging fine enforcement at the appellate level. The underlying utility model patent BRMU8902584U2 remains in force as a commercial risk factor.

Official order — verbatim text
The court’s formulation — ‘I GRANT the appeal, in order to dismiss the enforcement of the punitive fine sought by the aggravated party’ — is a targeted dispositif: it addresses the fine enforcement question specifically, without on its face adjudicating the validity of patent BRMU8902584U2 or any underlying infringement finding. At the appellate level, granting an appeal to dismiss an enforcement measure typically indicates the lower court’s basis for imposing or permitting the fine was found legally deficient. The ruling is consequential for Leroy Merlin commercially but leaves Fabinject’s broader patent rights formally intact.
BRMU8902584U2 — Modular Awning Arrangement (Brazilian Utility Model)
BRMU8902584U2 is a Brazilian utility model registration — designated by the ‘MU’ prefix under Brazil’s industrial property system — covering an arrangement for a modular awning. Utility models in Brazil offer a streamlined grant pathway relative to invention patents, typically protecting functional configurations of objects. The ‘U2’ suffix indicates a granted utility model. The modular awning arrangement likely encompasses structural configurations enabling assembly, adjustment, or connection of awning components, relevant to both retail and construction product markets.
For competitors and retailers in Brazil’s home improvement sector, BRMU8902584U2 represents a live enforcement asset. Modular awning systems are a mainstream product category in large-format DIY retail — stocked by chains such as Leroy Merlin — making the patent’s scope commercially significant. Manufacturers and importers of modular canopy or awning products destined for the Brazilian market should assess their exposure to this utility model, particularly given that the patent holder has demonstrated willingness to pursue enforcement through punitive fine mechanisms.
Should you run an FTO against BRMU8902584U2?
Any company manufacturing, importing, or retailing modular awning or canopy systems in Brazil should treat BRMU8902584U2 as a priority FTO target. Fabinject’s enforcement action against Leroy Merlin — one of Brazil’s largest home improvement retailers — confirms the patent is being actively asserted. Product developers and sourcing teams working on modular shade structures, retractable awnings, or canopy assembly systems should map their designs against the utility model’s claims before market entry.

What this case signals for the Brazilian home improvement IP landscape
This appellate outcome at the Court of Justice of São Paulo offers instructive signals for IP enforcement strategy in Brazil’s retail and manufacturing sectors.
Punitive fine enforcement in Brazilian IP cases is appellate-challengeable
Leroy Merlin’s success demonstrates that punitive fines sought in Brazilian patent enforcement proceedings are not automatically upheld. Companies facing such claims should assess whether the underlying procedural requirements were properly satisfied before accepting fine liability — an appellate challenge can be commercially decisive.
Utility model patents in consumer products remain active enforcement tools in Brazil
BRMU8902584U2 is a utility model — a faster-grant, shorter-term IP right under Brazilian law. Fabinject’s willingness to pursue punitive fines confirms these rights are being actively leveraged against large retailers. Product teams sourcing or developing modular awning systems for the Brazilian market should treat utility models as a live FTO risk.
Bricolagem v Fabinject — key questions answered
The Court of Justice of São Paulo granted Leroy Merlin’s appeal, dismissing the enforcement of the punitive fine that Fabinject had sought. The case was closed on 14 April 2025. The ruling addressed the fine enforcement question specifically and does not appear to resolve the underlying patent validity or infringement dispute concerning BRMU8902584U2.
BRMU8902584U2 is a Brazilian utility model registration held by Fabinject Indústria Plástica Ltda. The ‘MU’ designation indicates a utility model under Brazil’s industrial property law (Law No. 9,279/1996), which protects functional configurations of objects. This specific utility model covers an arrangement for a modular awning — a product category relevant to home improvement retail and residential construction markets in Brazil.
Granting the appeal means the appellate court found reversible error in the lower court’s position regarding the punitive fine enforcement. The fine sought by Fabinject against Leroy Merlin was dismissed as a result. Importantly, granting an appeal on a fine enforcement issue does not necessarily constitute a ruling on whether the underlying patent was valid or infringed — those questions may remain open in separate proceedings.
Not necessarily. The appellate ruling specifically addressed the enforcement of a punitive fine — it did not purport to adjudicate infringement or validity of BRMU8902584U2 on the merits. The public record of this case is silent on whether a separate infringement proceeding is ongoing. Companies should not interpret the dismissal of a fine enforcement claim as a clearance finding on the underlying patent.
This case highlights that Brazilian utility model holders are willing to pursue punitive fine enforcement against major retail chains, not just manufacturers. Retailers importing or selling modular awning systems in Brazil face exposure under active utility models such as BRMU8902584U2. A freedom-to-operate analysis covering relevant Brazilian utility model registrations is advisable before listing or sourcing such products, given the demonstrated enforcement posture of rights holders in this sector.
