The Verdict & Legal Analysis
Outcome
The Court of Justice of São Paulo, in its appellate ruling on March 9, 2026, issued a dispositive ruling: “In light of the foregoing, I vote to deny. The appeal is granted.” This means **Zenker Metallurgical’s infringement action was denied**, and BE1 Technology prevailed, avoiding liability under patent BR102016028566B1. No damages or injunctive relief details were disclosed.
Key Legal Issues
The appellate court’s decision suggests a finding of insufficient grounds to sustain Zenker’s infringement theory under Brazil’s Industrial Property Law (Law No. 9,279/1996). Brazilian patent litigation often involves rigorous claim-by-claim comparison between the asserted patent claims and the accused product’s features. A denial at this stage typically reflects a claim construction outcome unfavorable to the patentee, or a factual finding that the accused product does not meet all claim limitations, reinforcing the high standard of proof required for infringement in specialized industrial equipment disputes.
