Carbon Blindados v. Ana Carolina Leal & Alex Cirillo: Appeal Granted
Carbon Blindados Ltda prevailed on appeal before the Court of Justice of São Paulo in an infringement action over BR102013026009B1, a patent covering a development process for steel kits used in ballistic protection. The appellate court granted the appeal in full, reversing the lower court’s position in favour of the patent holder.
Ballistic armour patent appeal succeeds at São Paulo appellate court
Carbon Blindados Ltda, a Brazilian company operating in the armoured vehicle and ballistic protection sector, brought an infringement action against individuals Ana Carolina Leal Severiano da Silva and Alex Cirillo concerning Brazilian patent BR102013026009B1. The patent protects a development process for steel kits designed for ballistic application — a specialised manufacturing method relevant to the armoured vehicle supply chain. The case was heard before the Court of Justice of São Paulo under case number 2208882-93.2024.8.26.0000.
The appeal was granted by the Court of Justice of São Paulo and formally closed on 6 November 2024. The appellate panel’s vote granted the appeal in the terms outlined in the decision, which suggests the lower court’s finding was overturned in favour of Carbon Blindados. This outcome restores or strengthens the patent holder’s position in the infringement dispute, though the specific relief awarded — whether damages, injunction, or both — is not fully detailed in the available public record.
The case file does not record a filing date, making it impossible to calculate total duration from the public record. The fact that the dispute was resolved at the Court of Justice of São Paulo’s appellate level — rather than settling or being dismissed — suggests Carbon Blindados pursued the matter through a full appellate hearing, consistent with an enforcement strategy aimed at establishing clear precedent over its ballistic steel process patent. What specific acts of infringement were alleged against the named individuals and what remedies were ultimately ordered remain unknown from the published record.

São Paulo appellate court grants appeal: what the ruling means for both parties
Appeal granted: lower court decision overturned
A granted appeal at the Court of Justice of São Paulo means the appellate panel found reversible error in the lower court’s decision. The phrase ‘I GRANT the appeal, in the terms outlined above’ indicates the appellate court accepted Carbon Blindados’ arguments and reversed or materially modified the first-instance outcome. The specific grounds — whether legal error, factual reassessment, or procedural defect — are not fully disclosed in the available record.
Appellate reversalCarbon Blindados’ infringement claim revived or upheld
As the appellant and patent holder, Carbon Blindados is the primary beneficiary of this ruling. A granted appeal typically means the lower court’s rejection or limitation of the infringement claim has been overturned, restoring the enforceability and commercial value of BR102013026009B1. The patent covering the ballistic steel kit development process now carries appellate backing, strengthening Carbon Blindados’ hand in any subsequent enforcement or licensing discussions.
Patent enforceability strengthenedDefendants face reinstated infringement exposure
The named defendants — Ana Carolina Leal Severiano da Silva and Alex Cirillo — now face the reinstated or expanded consequences of the original infringement claim. With the appeal granted against them, their exposure to damages, injunctive relief, or other remedies under Brazilian IP law is materially increased. Further challenge would require an appeal to a higher court, raising costs and the legal bar for overturning this outcome.
Infringement exposure reinstatedAppellate win reinforces armoured steel process IP in Brazil
This outcome signals that Brazilian appellate courts are willing to enforce process patents in the specialised ballistic protection manufacturing sector. For competitors and suppliers operating in Brazil’s armoured vehicle supply chain, the ruling suggests that process-based patents covering ballistic steel kit development carry meaningful appellate-level enforceability — raising the risk calculus for any party operating in proximity to Carbon Blindados’ patented methodology.

Official order — verbatim text
The appellate panel’s ruling — ‘I GRANT the appeal, in the terms outlined above’ — is a definitive appellate disposition in favour of Carbon Blindados. Under Brazilian civil appellate procedure, a granted appeal typically means the first-instance decision contained a legal or factual error that the appellate court found sufficient to reverse or modify. The single-vote formulation is consistent with a collegiate panel adopting the reporting judge’s vote. The phrase ‘in the terms outlined above’ suggests the full scope of relief is detailed in the substantive reasoning, which is not reproduced in the available case data. For the defendants, this leaves no doubt that their position from the lower court has been overturned at this appellate tier.
BR102013026009B1 — Steel kit development process for ballistic application
BR102013026009B1 protects a development process for steel kits designed for ballistic application — a manufacturing methodology relevant to the production of armoured panels and protective structures used in vehicles, personal protection, and security installations. The application number prefix ‘BR1020130’ indicates a Brazilian national patent application filed in 2013, with the ‘B1’ suffix denoting a granted patent with examined claims. The technical domain sits at the intersection of metallurgy, materials science, and ballistic engineering, covering how steel components are specified, processed, and assembled for protective use.
For the Brazilian armoured vehicle and security sectors, this patent represents a defensible process claim that competitors cannot easily design around without understanding the specific processing steps protected. Carbon Blindados’ willingness to pursue infringement through to appellate courts demonstrates a commitment to active enforcement. Any supplier, manufacturer, or integrator working with ballistic-grade steel kits in Brazil should treat BR102013026009B1 as a live enforcement risk and assess their own processes against its claim scope before commercialisation.
Should you run an FTO against BR102013026009B1?
If your organisation manufactures, supplies, or integrates steel-based ballistic protection components in Brazil — whether for armoured vehicles, security installations, or personal protection equipment — this patent is directly relevant to your freedom-to-operate position. The appellate grant in this case confirms that the patent holder is both willing and capable of pursuing infringement claims through the Brazilian court system to a successful conclusion. Any process for developing steel kits intended for ballistic use warrants review against BR102013026009B1’s claim scope.

What this case signals for the ballistic protection IP landscape in Brazil
A successful appellate enforcement of a process patent in ballistic steel manufacturing carries sector-wide implications for IP strategy in Brazil.
Process patents in ballistic manufacturing are actively enforced in Brazil
This case confirms that Brazilian courts — including at appellate level — will entertain and uphold infringement claims tied to process patents in the armoured vehicle and ballistic protection sector. Companies operating in this space should treat process IP as a genuine enforcement risk, not merely a defensive filing.
Individual defendants signal internal IP leakage risk
The fact that named defendants are individuals rather than competing companies suggests the alleged infringement may relate to insider knowledge or personnel movement. IP owners in technically specialised sectors like ballistic armour manufacturing should review confidentiality, non-compete, and trade-secret protections alongside patent filings.
Ltda v Ana — key questions answered
The Court of Justice of São Paulo granted Carbon Blindados’ appeal on 6 November 2024, overturning the lower court’s decision in an infringement action concerning patent BR102013026009B1, which covers a development process for steel kits used in ballistic applications.
BR102013026009B1 is a granted Brazilian patent protecting a development process for steel kits designed for ballistic application. Filed in 2013, the patent covers a manufacturing methodology in the armoured protection and ballistic steel sector, held by Carbon Blindados Ltda.
At the Court of Justice of São Paulo, a granted appeal means the appellate panel found reversible error in the lower court’s decision and overturned or materially modified it. In the context of an infringement action, this typically restores or expands the patent holder’s claim against the defendants, potentially reinstating damages or injunctive relief.
Brazilian IP law permits infringement actions against individuals, not only corporate entities. The involvement of named individuals as defendants in this case is consistent with allegations of personal participation in infringing acts — potentially involving insider knowledge, trade secret misuse, or direct manufacture — though the specific allegations are not fully disclosed in the available public record.
Following the granted appeal, BR102013026009B1 carries heightened enforceability risk in Brazil. Any manufacturer, supplier, or integrator working with steel-based ballistic protection components should assess their processes against the patent’s claims. Carbon Blindados has demonstrated active enforcement posture through appellate courts, raising the litigation risk for potential infringers operating in Brazil.
