The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo **rejected all declaratory motions** filed by plaintiff Luciano Tanz, and the appeal was dismissed. The verdict states plainly: *”In view of the foregoing, by my vote, I reject the declaratory motions.”* This procedural outcome did not adjudicate the underlying merits of patent validity or infringement, but rather affirmed that the plaintiff’s declaratory action was not properly sustained.
Key Legal Issues
The operative legal vehicle here was a **Declaratory Judgment** action — a mechanism by which a party seeks a court’s authoritative declaration regarding the existence, scope, or validity of legal rights. In the Brazilian civil procedure context (governed by the Código de Processo Civil), declaratory actions require the plaintiff to demonstrate a genuine legal interest in having a right or legal relationship judicially confirmed or denied. The court’s rejection suggests the plaintiff failed to establish sufficient legal interest to sustain the declaratory action, or that the relief sought was procedurally improper given the posture of the underlying rights dispute.

The case involved Brazilian patent BRPI0513675B1, covering vertical wind tunnel recirculation systems with reduced drag cable technology for indoor skydiving facilities.
The Court of Justice of São Paulo rejected the declaratory motions and dismissed the appeal, though the specific legal reasoning beyond the recorded verdict was not fully detailed in available case data. This suggests the plaintiff failed to establish sufficient legal interest to sustain the action or that the relief sought was procedurally improper.
The dismissal reinforces procedural rigor in Brazilian declaratory actions and leaves the subject patent’s enforceability uncontested through this proceeding — a significant outcome for market participants in the indoor skydiving technology sector. It means the patent holder’s rights are still potentially enforceable.
R&D teams developing wind tunnel or simulation technology should conduct robust Freedom to Operate (FTO) analysis with respect to Brazilian national phase patents (BRPI series) before deployment. This case highlights that patent rights in niche recreational technology sectors are actively litigated in Brazil.
