The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo **dismissed the appeal with determination** (*negou provimento ao recurso*), affirming the lower court’s ruling. No specific damages amount was disclosed in the available case data, bringing finality to this phase of the litigation.
Key Legal Issues
The appellate court’s ruling included a clear warning against filing **merely dilatory motions for clarification** (*embargos de declaração protelatórios*), threatening financial sanctions for such tactics. This highlights the São Paulo court’s alignment with national standards for procedural good faith, aiming for efficiency under Brazil’s 2015 Code of Civil Procedure.
The court cited established Brazilian jurisprudence:
“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.” — EDcl no MS 21315-DF, Rel. Min. Diva Malerbi, TRF 3rd Region, June 8, 2016.
This ruling reinforces the enforceability of Brazilian utility model patents and emphasizes the judiciary’s increasing intolerance for procedural delays in IP litigation.
