Case Overview
The Parties
⚖️ Plaintiff/Appellant
Individual inventor and patent holder asserting rights over portable blasting machine technology under two Brazilian patent registrations.
🛡️ Defendant/Appellee
Operates in Brazil’s industrial manufacturing and commerce sector, designated as a limited liability commercial entity.
Patents at Issue
This litigation centers on two Brazilian patent documents crucial for portable spent blasting machine technology designed to couple with angled grinding recirculators:
- • BRPI2006854A2 — Earlier-generation patent application for foundational portable blasting machine technology.
- • BR102013018503B1 — Granted Brazilian patent covering jet-based spent blasting machines configured for coupling with portable angled grinding equipment.

The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo **denied the appeal in its entirety** on April 26, 2024, issuing a ruling described as decided “by Right Provision.” The court’s stated reasoning — *”There is, therefore, nothing to be changed”* — reflects a standard of appellate review that found no reversible error, procedural irregularity, or legal misapplication sufficient to disturb the lower court’s findings. No damages figures, injunctive relief terms, or settlement amounts were disclosed in the available case record.
Key Legal Issues
The verdict cause classification of **”Other Action”** is procedurally significant. Under Brazilian civil procedure, patent-related claims may be pursued through multiple legal pathways, including nullity actions, unfair competition claims, or tort-based IP claims, rather than exclusively through direct infringement suits. This classification suggests the underlying legal theory may have extended beyond conventional infringement analysis.
The appellate court’s deference to the lower tribunal, expressed through unqualified affirmance language, indicates that the record presented on appeal did not introduce new arguments or evidence capable of shifting the outcome. Brazilian appellate review at the TJSP level typically focuses on questions of law and procedural correctness rather than full re-examination of facts, which structurally limits appellants’ ability to reverse findings already established at the trial level.
