The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo **granted the appeal**, annulling the prior judgment issued by the court of origin and ordering the case file returned to the trial court for **regular evidentiary instruction**. No damages award or injunctive relief ruling is reflected in the appellate decision — the merits of the infringement claim remain unresolved pending further factual development at the trial level.
Verdict Cause Analysis
The appellate verdict does not resolve the underlying infringement question; rather, it addresses a **procedural deficiency** in how the original judgment was reached. The annulment on grounds of inadequate evidentiary instruction signals that the first-instance court rendered a decision — whether for or against the plaintiff — without permitting the full development of the factual record through witness testimony, expert opinions, technical inspections, or documentary evidence required under Brazilian civil procedure (Código de Processo Civil, Law No. 13,105/2015). In patent infringement cases involving technical subject matter such as pre-molded wall panel systems, evidentiary instruction typically requires technical expert reports (laudos periciais), documentary evidence, potential site inspections, and prior art analysis relevant to patent validity.
This ruling reinforces a vital principle for patent infringement cases in Brazilian courts: **technical complexity demands technical evidence**. Courts cannot resolve construction patent disputes on pleadings or abbreviated records. The annulment creates a procedural reset, preserving both parties’ ability to fully present their cases on the merits.

The case involves Brazilian patent application BRPI1702979A2, covering pre-molded wall panel technology. The application is searchable via INPI (Instituto Nacional da Propriedade Industrial), Brazil’s patent office.
The appellate court found the trial court issued its decision without completing regular evidentiary instruction — meaning the factual record was insufficiently developed to support a valid ruling on the infringement claim.
The remand signals that Brazilian courts require thorough technical evidence in construction patent cases. Companies in this space should conduct proactive FTO analysis and prepare for technically rigorous evidentiary proceedings.
