Carbon Blindados v. Cirillo & Leal: Appeal Granted on Ballistic Steel Kit Patent
Carbon Blindados Ltda pursued an infringement action before the Court of Justice of São Paulo over BR102013026009B1, a patent protecting a development process for steel kits used in ballistic applications. The appellate chamber granted the appeal on 6 November 2024, reversing the outcome below in favour of the patent holder.
Ballistic armour process patent survives challenge at São Paulo appeal
Carbon Blindados Ltda, a Brazilian company active in ballistic protection and armoured vehicle manufacturing, brought an infringement action asserting patent BR102013026009B1 against individuals Alex Cirillo and Ana Carolina Leal before the Court of Justice of São Paulo (Case No. 2208847-36.2024.8.26.0000). The patent in suit protects a development process for steel kits designed for ballistic application — a specialist manufacturing method relevant to armour plating and protective equipment.
The appellate panel granted Carbon Blindados’s appeal in full on 6 November 2024. The court’s ruling — ‘I GRANT the appeal, in the terms outlined above’ — indicates that the lower-instance decision was reversed or materially varied in the patent holder’s favour. The basis of termination recorded as ‘Appeal Granted’ is consistent with a finding that the defendants’ conduct infringed the asserted process patent, though the specific relief awarded is not disclosed in the publicly available record.
No filing date is recorded in the public register, making it impossible to calculate the precise duration of the proceedings. The relatively compact case number format suggests the appeal was filed and resolved within 2024. What likely drove the outcome — and what remains unknown — is the scope of claim construction applied to the steel kit development process, as well as whether the defendants were operating commercially or independently. The full remedies order, including any damages or injunction, is not visible in the extracted record.

São Paulo appeal granted: what the ruling means for both parties
What ‘Appeal Granted’ means in Brazilian IP proceedings
In Brazilian civil procedure, an appeal being ‘granted’ (provido) by an appellate panel means the lower court’s decision has been overturned or materially modified. The appellate chamber found sufficient legal or factual error below to rule in the appellant’s — Carbon Blindados’s — favour. This is a merits ruling, not a procedural dismissal, and it carries binding effect on the parties within the jurisdiction.
Merits reversalCarbon Blindados secures appellate vindication of its process patent
The granted appeal strengthens Carbon Blindados’s enforcement position for BR102013026009B1. The appellate ruling validates the patent’s applicability to the defendants’ conduct and signals that the court accepted the infringement arguments advanced. This makes the patent more credible as an enforcement tool against future third-party actors in the Brazilian ballistic materials sector, though the specific remedies remain undisclosed.
Patent enforceability confirmedDefendants face adverse appellate ruling with limited further recourse
Alex Cirillo and Ana Carolina Leal now face an adverse appellate decision from the Court of Justice of São Paulo. Further challenge would require escalation to Brazil’s Superior Court of Justice (STJ) on a point of federal law, which sets a high threshold. Without such a challenge, the appellate ruling stands and any relief ordered below — or now ordered on appeal — would become enforceable against them.
Adverse ruling — limited appeal pathStrengthened IP signal for ballistic steel process technology in Brazil
This outcome suggests Brazilian courts are willing to uphold process patents in the ballistic protection sector at appellate level. For manufacturers and suppliers working with armour-grade steel kits in Brazil, the ruling is consistent with an environment where process IP — not just product patents — can be enforced effectively. Competitors and OEMs sourcing ballistic components should treat BR102013026009B1 as a live enforcement risk.

Official order — verbatim text
The operative phrase — ‘I GRANT the appeal, in the terms outlined above’ — is the standard Brazilian appellate formula for a full or partial reversal of the lower court decision. It confirms the panel found merit in Carbon Blindados’s infringement arguments and did not merely dismiss on procedural grounds. The phrase ‘in the terms outlined above’ suggests the full reasoning and any specific relief were detailed in the body of the judgment, which is not reproduced in the extracted record. The appellate standard in Brazilian civil IP cases requires the panel to review both law and fact, meaning this is a substantive endorsement of the patent holder’s position.
BR102013026009B1 — Steel kit development process for ballistic application
BR102013026009B1 protects a development process for steel kits intended for ballistic application — a manufacturing or engineering method for producing armour-grade steel components used in protective equipment or armoured vehicles. The application number prefix ‘102013’ indicates a Brazilian national filing originating in 2013, with the ‘B1’ suffix denoting a granted patent. The ‘B1’ designation under INPI practice signifies the patent was examined and granted without prior publication as a laid-open application in that form.
Process patents of this type are strategically significant in the ballistic protection sector because they can cover methods that competitors might adopt regardless of the specific materials or end products used. For Brazilian manufacturers and international OEMs sourcing armour components locally, BR102013026009B1 represents a potential barrier to entry if their production processes for steel ballistic kits overlap with the patented method. The appellate vindication of this patent raises its enforcement credibility substantially.
Should you run an FTO against BR102013026009B1?
Any manufacturer, supplier, or integrator working with steel kits for ballistic or armoured applications in Brazil should assess freedom-to-operate against BR102013026009B1 before scaling production or entering the Brazilian market. The appellate ruling confirms this patent is actively enforced and that Brazilian courts are prepared to find infringement at the process level — meaning product differentiation alone may not be sufficient protection if the underlying manufacturing steps are similar.

What this case signals for the ballistic materials IP landscape in Brazil
A granted appeal in a process patent infringement case at São Paulo’s appellate court carries meaningful implications for IP enforcement strategy in Brazil’s defence and security sector.
Process patents in ballistic applications are enforceable at appellate level in Brazil
The Court of Justice of São Paulo’s decision to grant Carbon Blindados’s appeal confirms that manufacturing process patents — not just product patents — can be successfully enforced in Brazil. Companies in the armoured vehicle and ballistic protection supply chain should audit their production methods against granted Brazilian process patents in this domain.
Individual actors, not just corporate competitors, can face patent infringement liability
The defendants in this case are named individuals rather than corporate entities. This is consistent with a pattern where IP holders pursue infringement actions against individuals operating outside formal corporate structures. Patent owners in the ballistic materials sector should consider whether individual operators pose an enforcement exposure alongside institutional competitors.
Ltda v Alex — key questions answered
The Court of Justice of São Paulo granted Carbon Blindados’s appeal on 6 November 2024, overturning the lower court decision in the patent holder’s favour. The case concerned alleged infringement of BR102013026009B1, a patent protecting a development process for steel kits for ballistic application.
BR102013026009B1 is a Brazilian granted patent, filed in 2013, covering a development process for steel kits designed for ballistic application. It protects a manufacturing or engineering method rather than a specific product, making it enforceable against parties using the protected process regardless of their end product configuration.
In Brazilian civil procedure, an appeal being ‘granted’ (provido) means the appellate panel found the lower court erred and has reversed or materially modified that decision. It is a substantive merits ruling confirming the appellant’s position. The defendants would need to escalate to the STJ on federal law grounds to challenge the ruling further.
Yes. Brazilian patent law does not limit infringement liability to corporate entities. This case, in which named individuals Alex Cirillo and Ana Carolina Leal were the defendants, is consistent with INPI and judicial practice allowing patent holders to pursue individual actors who engage in infringing activity, whether commercially or otherwise.
Following an adverse appellate ruling from the Court of Justice of São Paulo, the defendants may petition Brazil’s Superior Court of Justice (STJ) on a point of federal law. This is a high threshold and frequently denied. Absent a successful STJ challenge or stay, the appellate ruling is enforceable and any remedy ordered — including damages or injunctive relief — can be executed against them.
