Aperçu du dossier
In a significant procedural victory for patent holders pursuing utility model rights in Brazil, the Court of Justice of São Paulo granted an appeal filed in case No. 2317825-44.2023.8.26.0000, ruling in favor of plaintiff Enio Bianchi against Appia Fabricação de Esquadrias Especiais Ltda ME. The appellate court reformed the contested lower-level decision, eliminating the requirement for new expert evidence to analyze whether acts of infringement of Patent BRMU8400847Y1 had been committed — a ruling with meaningful implications for vibration damper patent litigation and utility model enforcement strategy throughout Latin America.
Closed on March 14, 2024, this case centers on an arrangement for a vibration damper for a device for opening gaps — a specialized mechanical component used in architectural hardware systems. While modest in commercial scale compared to high-profile multinational disputes, the court’s reasoning carries strategic weight for patent attorneys navigating evidentiary standards in Brazilian IP litigation, in-house counsel managing utility model portfolios, and R&D teams operating in the construction hardware and fenestration sector.
Les parties
⚖️ Demandeur
An individual inventor-entrepreneur holding utility model rights under Brazilian IP law, Bianchi pursued enforcement of his registered patent against a direct market competitor. Individual inventors asserting utility model patents represent a growing segment of Brazilian IP litigation.
🛡️ Défendeur
A Brazilian manufacturer specializing in the fabrication of special frames and architectural fittings (*esquadrias especiais*). The company’s operations place it squarely within the technical domain covered by Bianchi’s patent.
Le brevet en cause
This case involved Brazilian Utility Model Patent BRMU8400847Y1, covering an arrangement for a vibration damper for a device for opening gaps — a specialized mechanical component used in architectural hardware systems. Brazilian utility model patents (*modelo de utilidade*) under Law No. 9,279/1996 protect functional improvements to existing objects or tools, offering a 15-year term from filing.

Le verdict et l'analyse juridique
Résultat
The Court of Justice of São Paulo **granted the appeal in full**, reforming the contested lower court decision. The specific ruling eliminated the requirement to produce new expert evidence for the purpose of analyzing whether acts of infringement of Patent BRMU8400847Y1 had occurred. No damages figures were disclosed in the available case record, consistent with this being an interlocutory appellate ruling on procedural/evidentiary grounds rather than a final merits judgment on damages.
Principales questions juridiques
The central legal question resolved by the appellate court was **evidentiary sufficiency**: whether new expert evidence was necessary to evaluate the infringement claim. The court concluded it was not, reforming the lower tribunal’s order accordingly. This signals that the appellate panel found sufficient basis in the existing record to proceed with infringement analysis without commissioning additional expert testimony — a meaningful efficiency determination with implications for how Brazilian courts manage evidentiary burdens in utility model cases.
Signification juridique
This ruling carries **procedural precedential value** for utility model enforcement in São Paulo state courts. The appellate decision reinforces that courts retain discretion to decline additional expert evidence where the record is sufficient — a principle that strengthens the hand of patent holders seeking to avoid costly, time-consuming court-appointed expert procedures (*perícia judicial*).
