Case Overview
The Parties
⚖️ Plaintiff
Individual inventor who holds Brazilian utility model patent BRMU8400847Y1. Bianchi initiated infringement proceedings against a corporate defendant.
🛡️ Defendant
Brazilian metallurgical manufacturing company operating in the industrial components space, accused of infringing Bianchi’s utility model patent.
The Patent at Issue
This landmark case involved Brazilian utility model patent BRMU8400847Y1, which covers an *arrangement for a vibration damper for a device for opening gaps*. Utility model patents in Brazil protect functional innovations with a lower inventive step threshold than invention patents, and are registered with the Brazilian National Institute of Industrial Property (INPI).

The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo **dismissed the appeal**, affirming the lower court’s decision and formally closing the case as of **March 19, 2024**. No specific damages award, settlement amount, or injunctive relief details were disclosed in the available record. The basis of termination is recorded as **Appeal Dismissed**.
Key Legal Issues
The appellate court’s ruling contained a pointed and strategically significant procedural warning: *”The parties are warned that the opposition of merely delaying motions for clarification may lead to the imposition of a fine, since ‘The judge is not obliged to answer all the questions raised by the parties, when he has already found sufficient reason to render the decision.'”* The court cited precedent from *EDcl no MS 21315-DF*. This language is legally significant as it reflects a broader judicial policy trend in Brazil toward efficiency enforcement and signals that Brazilian courts — including the commercially important TJSP — are increasingly willing to impose financial penalties on parties who weaponize procedural motions.
