Supertec & Vitrotec v. Markom: São Paulo Court Dismisses Ballistic Shield Patent Appeal
Supertec Equipamentos de Proteção and Vitrotec Vidros de Segurança filed suit against Markom Comercial Ltda over patent BRPI9204323A2, covering interchangeable ballistic shielding systems for automobiles. The Court of Justice of São Paulo dismissed the appeal on 30 April 2025, ending the proceeding without a merits ruling on the underlying patent dispute.
São Paulo appellate court ends ballistic shielding patent dispute at procedural stage
The plaintiffs, Supertec Equipamentos de Proteção Ltda and Vitrotec Vidros de Segurança Ltda, initiated proceedings against Markom Comercial Ltda before the São Paulo state courts, asserting rights under Brazilian patent application BRPI9204323A2, which covers interchangeable ballistic shielding technology for automobiles — a product category with distinct commercial relevance in the Brazilian security and armoured vehicle market.
The Court of Justice of São Paulo dismissed the appeal on 30 April 2025 under the classification ‘Appeal Dismissed,’ consistent with a procedural termination rather than a substantive adjudication of the patent claims. The dismissal means neither party received a merits determination on patent validity or infringement from the appellate court, and the underlying rights under BRPI9204323A2 were not authoritatively resolved at this level.
Because the outcome reflects a procedural dismissal, it is not possible to infer from the public record whether the appellants failed to satisfy formal requirements or whether a prior lower-court ruling remains operative. The absence of a filing date and duration data further limits external analysis. Parties operating in the Brazilian ballistic shielding or armoured vehicle aftermarket should note that the patent’s enforceability and scope have not been conclusively settled by this proceeding.

Appeal dismissed in São Paulo: what the procedural ruling means for both parties
A dismissed appeal leaves the merits untouched
When an appellate court dismisses an appeal — as the Court of Justice of São Paulo did here — it terminates the appellate proceeding without ruling on the substance of the dispute. The court found a basis to end the case at the procedural level, meaning no binding appellate finding was made on patent validity, scope, or infringement of BRPI9204323A2. Any operative lower-court decision would typically remain in place, though the public record does not clarify that position here.
Procedural — no merits rulingPlaintiffs’ appeal ends without appellate vindication
For Supertec and Vitrotec as appellants, the dismissal means their challenge did not advance to a substantive hearing. They did not obtain an appellate ruling reinforcing their patent position or overturning any adverse lower-court finding. Further recourse, if available, would likely require satisfying different procedural thresholds or pursuing alternative enforcement avenues within the Brazilian IP enforcement framework.
Appellant — no appellate relief obtainedMarkom avoids an appellate merits ruling — for now
Markom Comercial Ltda benefits from the dismissal insofar as it faced no adverse appellate determination on infringement or validity. However, because the dismissal is procedural, Markom cannot treat this as a definitive finding that it does not infringe BRPI9204323A2 or that the patent is invalid. The underlying patent rights remain formally unresolved, and future enforcement action by the patent holders cannot be excluded.
Respondent — no merits finding against itPatent status unresolved — market uncertainty persists
Companies active in Brazilian armoured vehicle shielding, ballistic glazing, or automotive protection aftermarkets should note that BRPI9204323A2 has not been invalidated or held unenforceable by this ruling. The dismissal leaves a degree of legal uncertainty that may affect freedom-to-operate assessments for competitors producing interchangeable ballistic shielding systems in or for the Brazilian market. A fresh FTO review against this patent application is advisable.

Official order — verbatim text
The court’s single operative line — ‘I DISMISS the appeal’ — is a hallmark of procedural termination under Brazilian civil procedure. It confirms the appellate chamber found a threshold deficiency that precluded merits review, whether relating to standing, timeliness, procedural form, or another admissibility ground. Critically, this phrasing issues no finding on the validity or infringement of BRPI9204323A2. For both parties, the legal position on the patent’s substance remains precisely where it stood before the appeal was filed.
BRPI9204323A2 — Interchangeable Ballistic Shielding for Automobiles
BRPI9204323A2 is a Brazilian patent application covering interchangeable ballistic shielding technology designed for installation in automobiles. The interchangeable design suggests the invention addresses modularity — enabling protective elements to be replaced or reconfigured without full vehicle modification — a commercially significant feature in the armoured vehicle and executive protection markets. The application’s numbering convention indicates an early-1990s filing, meaning the patent is mature and any term extension possibilities are limited.
In the Brazilian security vehicle sector, proprietary ballistic shielding configurations can confer meaningful competitive advantage, particularly where interchangeability reduces retrofit costs for fleet operators. The joint assertion of this patent by a ballistic equipment firm and a security glazing specialist suggests a coordinated IP position spanning both structural shielding and transparent armour. Competitors active in this niche should evaluate whether their product configurations fall within the application’s claims, especially given the unresolved appellate status of this litigation.
Should you run an FTO against BRPI9204323A2?
Any company manufacturing, importing, or distributing interchangeable ballistic shielding systems for automobiles in Brazil should treat BRPI9204323A2 as an active risk factor. The São Paulo appellate dismissal has not resolved the patent’s validity or scope, and the application remains formally asserted by two rights holders. Armoured vehicle converters, Tier 1 protection suppliers, and aftermarket ballistic glazing companies are the most directly exposed commercial actors.

What this case signals for the ballistic protection IP landscape in Brazil
A procedural dismissal at appellate level in São Paulo leaves a long-standing ballistic shielding patent unresolved — and the market exposed.
Procedural dismissals do not extinguish underlying patent rights
BRPI9204323A2 has not been declared invalid or unenforceable. Companies in the Brazilian armoured vehicle or ballistic glazing supply chain should not interpret this dismissal as clearance. The patent holders retain the ability to initiate fresh enforcement proceedings if procedural deficiencies are cured.
Brazilian state court patent litigation carries distinct procedural risks
This case illustrates that patent disputes litigated through Brazil’s state appellate courts — rather than the federal IP track — can be resolved on procedural grounds before merits are reached. IP teams pursuing enforcement in Brazil should scrutinise filing requirements and appeal formalities with particular care to avoid similar outcomes.
LTDA v MARKOM — key questions answered
The court dismissed the appeal on 30 April 2025. This is a procedural termination — the appellate chamber did not rule on the merits of the patent dispute involving BRPI9204323A2. No finding on patent validity or infringement of the interchangeable ballistic shielding technology was issued.
The patent at issue is BRPI9204323A2, a Brazilian patent application covering interchangeable ballistic shielding for automobiles. It was jointly asserted by Supertec Equipamentos de Proteção Ltda and Vitrotec Vidros de Segurança Ltda against Markom Comercial Ltda.
No. A procedural dismissal carries no finding on validity or enforceability. BRPI9204323A2 has not been declared invalid or held unenforceable by this ruling. The patent’s legal status on the merits remains unresolved, and the rights holders could potentially pursue further enforcement action.
The public record does not specify the precise legal relationship between the two plaintiffs. The joint filing is consistent with co-ownership of BRPI9204323A2 or an arrangement where both entities held rights to assert the patent. Parties conducting IP due diligence in this space should verify the ownership structure before transacting.
The dismissal leaves the legal status of BRPI9204323A2 unresolved. Manufacturers, importers, and distributors of interchangeable automotive ballistic shielding in Brazil cannot treat this ruling as clearance. An FTO analysis against the patent application is advisable for any commercial actor in the Brazilian armoured vehicle or protective glazing sector.
