Le verdict et l'analyse juridique
Résultat
The Court of Justice of São Paulo **granted the appeal**, setting aside the lower court sentence and ordering the **production of new expert evidence**. This means the appellate court did not render a final substantive ruling on the declaratory judgment claim but remanded the matter for further technical analysis. No damages award or injunctive relief was determined at this stage.
Principales questions juridiques
The appellate court’s decision to vacate and remand on evidentiary grounds strongly implies that the original expert evidence — a technical report evaluating whether the accused cloth diaper product fell within the claims of BR102012017905B1 — was found to be insufficient, procedurally defective, or methodologically inadequate to support the trial court’s conclusions. This highlights the **Brazilian appellate courts’ rigorous approach to expert evidence in IP matters**, signaling that declaratory patent judgments cannot rest on inadequate technical analysis.
