Case Overview
The Parties
⚖️ Plaintiff
Individual inventor and patent holder, asserting rights over a constructive innovation applied to sliding sheave door mechanisms.
🛡️ Defendant
Brazilian limited liability company operating in the animal products sector, with products likely including enclosures featuring sliding door assemblies.
The Patent at Issue
This landmark case involved a crucial **Brazilian Utility Model patent (BR202020012225U2)** covering a fundamental mechanical design element for sliding doors. Utility models (Modelos de Utilidade) are registered with the Brazilian National Institute of Industrial Property (INPI) and protect functional and structural improvements to existing objects.

The Verdict & Legal Analysis
Outcome
The **Court of Justice of São Paulo** **denied the interlocutory appeal** (agravo de instrumento), filed by the defendant Alfapet. This ruling, closed on **August 21, 2024**, reinforces the lower court’s authority over the underlying infringement dispute and signifies a procedural setback for the appellant. No damages award was issued at this interlocutory stage.
Key Legal Issues
The Brazilian appellate court’s decision focused on procedural aspects of interlocutory appeals under the Código de Processo Civil and the preliminary assessment of utility model scope. The denial indicates the appellate panel found no clear legal error to disturb the lower court’s interim determination. This affirms the initial standing of the plaintiff’s infringement claim regarding the “disposição construtiva aplicada em polia deslizante para portas” (constructive arrangement applied in sliding sheave for doors) under Brazil’s Industrial Property Law (Lei nº 9.279/1996).
