Unifila Brasil v. De Lorenzo & Uni Store — Appeal Dismissed, Case Proceeds
Unifila Brasil Indústria Metalúrgica Ltda brought proceedings against Ricardo Augusto de Lorenzo and Uni Store Comercial Ltda before the Court of Justice of São Paulo over Brazilian utility model BRMU8400821Y1, covering a brake mechanism for ribbon cartridges used in line-organization poles. The court dismissed the appeal, finding the underlying claim must follow its normal procedure.
São Paulo court dismisses appeal, orders claim to proceed on merits
Unifila Brasil Indústria Metalúrgica Ltda, a Brazilian metalworking manufacturer, initiated proceedings against Ricardo Augusto de Lorenzo and associated trading entity Uni Store Comercial Ltda at the Court of Justice of São Paulo (Case No. 2054315-70.2025.8.26.0000). The dispute centres on utility model patent BRMU8400821Y1, which protects a constructive arrangement in the brake of a ribbon cartridge used in poles designed for organizing lines or cables.
The court’s ruling, dated 18 March 2025, dismissed the appeal on the basis that the content of the claim requires the process to follow its normal procedural course. This is a procedural, not substantive, disposition: the appellate court did not adjudicate the merits of the underlying patent claim, instead returning the matter to ordinary proceedings. The appeal dismissal does not itself resolve questions of infringement or validity.
Because no filing date is recorded in the available public data, the overall duration of proceedings cannot be assessed. The procedural nature of the dismissal means the substantive dispute — whether the brake ribbon cartridge design was infringed by the defendants — remains unresolved in the public record. What likely drove the dismissal was a finding that the appeal was premature or procedurally improper relative to the stage of the underlying action.

Appeal dismissed: what the ruling means for both parties
Procedural dismissal — no merits ruling on the patent claim
The Court of Justice of São Paulo dismissed the appeal on the grounds that the underlying claim must follow its normal procedure. This is a purely procedural outcome: the court made no finding on infringement or the validity of BRMU8400821Y1. The dismissal suggests the appeal was brought before the underlying proceedings had reached a stage that permitted appellate review under Brazilian civil procedure rules.
No merits adjudicationUnifila’s substantive claim survives and continues
For Unifila Brasil, the dismissal is not a defeat on the merits. The court’s direction that the claim must follow its normal procedure confirms the underlying action remains live. Unifila retains the opportunity to pursue its patent rights against De Lorenzo and Uni Store through the ordinary litigation track, with BRMU8400821Y1 still capable of being enforced if the lower court rules in its favour.
Claim remains activeDefendants face ongoing proceedings without appellate relief
Ricardo Augusto de Lorenzo and Uni Store Comercial Ltda did not obtain a final resolution through this dismissal. The underlying patent dispute continues, meaning the defendants must still respond to Unifila’s claim on the merits in the lower court. No finding of non-infringement or invalidity of BRMU8400821Y1 was made, leaving their exposure to the patent claim unresolved.
Exposure unresolvedRibbon cartridge brake IP dispute continues in Brazilian courts
For manufacturers and distributors of line-organization hardware — including brake ribbon cartridge assemblies and pole systems — this case signals that Unifila Brasil is actively enforcing BRMU8400821Y1 through Brazilian courts. The procedural dismissal extends rather than ends uncertainty. Competitors and retailers distributing similar products in Brazil should monitor the underlying proceedings as the merits phase develops.

Official order — verbatim text
The court’s ruling that ‘the process must follow its normal procedure’ and that ‘the present appeal is dismissed’ is a procedural disposition under Brazilian civil procedure. It does not engage with the substantive patent claim or the merits of alleged infringement of BRMU8400821Y1. For Unifila Brasil, the ruling preserves the underlying action; for the defendants, it removes the protective effect of any interim appellate argument without granting affirmative relief. The matter reverts to first-instance proceedings.
BRMU8400821Y1 — Brake mechanism in ribbon cartridge for line-organization poles
BRMU8400821Y1 is a Brazilian utility model patent held by Unifila Brasil Indústria Metalúrgica Ltda. It protects a constructive disposal — meaning a specific structural or assembly arrangement — in the brake of a ribbon cartridge designed for use in poles that organize lines or cables. Utility models in Brazil (‘modelo de utilidade’) protect functional improvements to the form or arrangement of objects, typically with a lower inventive step threshold than invention patents and a 15-year maximum term from filing.
For the line-organization and cable management hardware sector, this utility model represents a targeted protection over a mechanical sub-assembly that controls ribbon tension or deployment in pole-mounted systems. Competitors manufacturing or importing functionally equivalent brake cartridge designs into Brazil face direct infringement risk while the patent remains in force. The ongoing enforcement action against a retailer (Uni Store) as well as a designer underscores that Unifila is pursuing a broad enforcement posture across the supply chain.
Should you run an FTO against BRMU8400821Y1?
Any manufacturer, importer, or distributor of ribbon cartridge brake assemblies or pole-mounted line-organization systems active in the Brazilian market should treat BRMU8400821Y1 as a live risk. The patent is being actively litigated, and the underlying merits proceedings are ongoing. Product teams designing or sourcing brake cartridge components structurally similar to the protected arrangement should commission an FTO before entering or expanding in Brazil.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map claim scope for Brazilian utility model patents, identify prior art that could limit enforceability, and benchmark product designs against the protected constructive arrangement. With the merits phase of this case still ahead, running an FTO now provides the clearest window to assess and document design-around options before a first-instance judgment is handed down.

What this case signals for the line-organization hardware IP landscape in Brazil
Unifila Brasil’s active enforcement of a utility model over a brake ribbon cartridge mechanism reflects the broader trend of Brazilian metalworking IP being litigated in São Paulo state courts.
Active enforcement of Brazilian utility models in manufacturing hardware
This case confirms that utility model protections in niche mechanical hardware — such as cable and line organization components — are being actively enforced in Brazil. Companies supplying similar pole or cartridge brake products into the Brazilian market should audit their supply chain against BRMU8400821Y1 before the underlying proceedings reach a merits decision.
Procedural dismissals in São Paulo do not end underlying IP disputes
A dismissed appeal at the Court of Justice of São Paulo, where the court directs normal procedure to continue, means the substantive risk to defendants is unchanged. In-house counsel tracking Brazilian IP exposure should treat this outcome as a deferral, not a resolution, and continue monitoring the lower court docket for a merits ruling on infringement.
Ltda v Ricardo — key questions answered
The appeal dismissal is procedural, not substantive. The Court of Justice of São Paulo found that the underlying claim must follow its normal procedure, meaning the first-instance proceedings over BRMU8400821Y1 continue. No finding was made on infringement or validity of the patent.
BRMU8400821Y1 protects a specific structural arrangement (constructive disposal) in the brake of a ribbon cartridge used in poles for organizing lines or cables. As a utility model, it covers a functional improvement to the form or assembly of the object rather than a new invention, with protection typically lasting up to 15 years from the filing date in Brazil.
The public record does not specify the precise basis for Uni Store’s inclusion, but the naming of a commercial retailer alongside an individual designer is consistent with Brazilian IP enforcement practice of pursuing downstream distributor liability. This approach can broaden the scope of relief available to a patent holder.
Yes. As the case proceeds to its merits phase in the lower court, the defendants may raise invalidity arguments — including lack of novelty or inventive step — as a defence to infringement. Prior art searches across Brazilian INPI utility model filings and international mechanical hardware patents may surface relevant prior art for such challenges.
The appeal dismissal made no finding on the validity or enforceability of BRMU8400821Y1. The patent remains in force unless and until it is invalidated or expires. Unifila Brasil’s continued litigation suggests the patent holder considers it enforceable, and the court’s direction to proceed with normal procedure keeps the enforcement action alive.
