Charada Peças v GRSUL: Anti-Theft Lock Patent Infringement Appeal Dismissed
Charada Peças e Acessórios para Autos EIRELI pursued an infringement action against GRSUL Componentes Automotivos Ltda over three Brazilian patents covering anti-theft locks for heavy vehicle components. The Court of Justice of São Paulo dismissed the interlocutory appeal, closing this procedural chapter. Three separate patents across fuel, clutch, and reducing agent systems were at stake.
Three anti-theft lock patents, one dismissed appeal in São Paulo
Charada Peças e Acessórios para Autos EIRELI filed an infringement action against GRSUL Componentes Automotivos Ltda at the Court of Justice of São Paulo (Case No. 2.288.122-68.2023.8.26.0000). The action centred on three Brazilian patents — BR102021006825B1, BR102021002978B1, and BR102021023643B1 — each protecting a distinct anti-theft locking mechanism applied to heavy vehicle components: a liquid reducing agent pump, a fuel tank float, and a clutch servo respectively.
The case reached the Court of Justice of São Paulo on an interlocutory appeal, which was dismissed on 6 February 2024. An interlocutory appeal targets a specific interim procedural or substantive ruling rather than the final merits of a case. Its dismissal means the appellate panel declined to intervene at this stage, leaving the underlying infringement proceedings to continue or conclude at the trial level without appellate correction of the contested interim order.
Because this outcome resolves only the interlocutory appeal and not the infringement action on its merits, the ultimate liability question between the parties remains unresolved in this public record. The relatively compact procedural history suggests the dispute may still be active at first instance. What drove the dismissal — whether procedural irregularity, timing, or lack of urgency — is not specified in the available public record.

Interlocutory appeal dismissed: what this means for both parties
What an interlocutory appeal dismissal actually means
An interlocutory appeal challenges a specific interim court ruling before final judgment. Its dismissal does not resolve the underlying infringement case on its merits — it means the appellate court declined to intervene at this procedural juncture. The original trial-level proceedings on the three anti-theft lock patents are unaffected by this dismissal in terms of ultimate liability.
No merits rulingCharada Peças: no appellate relief, but case continues
If Charada Peças was the appellant seeking to reverse an interim ruling, the dismissal is a setback at this procedural stage. However, it does not extinguish the infringement claims. The three patents remain in force, and Charada retains the ability to pursue its infringement action at the trial level. The commercial exclusivity sought over its anti-theft lock technology is not yet definitively adjudicated.
Claims survive dismissalGRSUL avoids interim appellate intervention — for now
The dismissal of the interlocutory appeal is procedurally advantageous for GRSUL in the short term, as it prevents an interim appellate ruling from disrupting its operations or imposing emergency injunctive relief. However, GRSUL still faces the substantive infringement allegations across three patent families covering heavy-vehicle locking systems — liability on those claims has not been resolved.
Merits still pendingAnti-theft IP in the Brazilian heavy-vehicle aftermarket remains contested
This case signals that proprietary anti-theft locking systems for heavy vehicles — covering fuel, exhaust treatment, and drivetrain components — are actively litigated assets in Brazil. Competitors and OEM suppliers operating in the Brazilian truck components aftermarket should monitor all three patent families. The outcome of the underlying infringement action could set a precedent for component-level security device protection in this segment.

Official order — verbatim text
The verdict — ‘the interlocutory appeal is dismissed’ — is a procedural disposition confined to the specific interim ruling under challenge and carries no merits determination on the underlying infringement claims. Under Brazilian civil procedure, interlocutory appeals (agravos de instrumento) are restricted to challenging defined categories of interim orders; dismissal typically reflects a failure to meet admissibility requirements or a finding that the interim order was within the trial court’s discretion. Neither the validity of the three anti-theft lock patents nor GRSUL’s alleged infringement has been adjudicated by this ruling.
BR102021006825B1, BR102021002978B1 & BR102021023643B1 — Heavy-Vehicle Anti-Theft Locks
The three asserted patents — BR102021006825B1, BR102021002978B1, and BR102021023643B1 — each protect a distinct anti-theft locking mechanism engineered for heavy commercial vehicles. The product scope spans the AdBlue/DEF reducing agent pump system, the fuel tank float assembly, and the clutch servo actuator. All three carry a B1 designation under INPI practice, indicating examination was completed and claims were granted. The 2021 application dates suggest a coordinated IP filing strategy across related truck security subsystems.
Strategically, this three-patent portfolio creates overlapping protection across critical and high-theft-risk subsystems of heavy trucks in the Brazilian market — a segment where fuel and fluid theft from stationary vehicles is a documented commercial problem. Any competitor producing aftermarket anti-theft devices for these specific component categories faces multi-front infringement exposure. The simultaneous assertion of all three patents in a single action raises the cost and complexity of any invalidity or non-infringement defence.
Should you run an FTO against BR102021006825B1, BR102021002978B1 & BR102021023643B1?
Any company manufacturing, importing, or distributing anti-theft devices for heavy commercial vehicle fuel tanks, AdBlue/DEF systems, or clutch servos in Brazil should treat these three patents as active FTO risks. The B1 grant status and the active enforcement posture demonstrated by this litigation make them priority assets to clear. Fleet security device suppliers and OEM aftermarket accessory manufacturers are the most directly exposed.
PatSnap Eureka’s FTO Search Agent can map the claim scope of each of the three Brazilian patents against your product’s technical features, identify prior art that may limit enforceability, and surface related filings in the same INPI patent family. Running separate FTO analyses per subsystem — reducing agent pump, fuel float, and clutch servo — is advisable given the independent claim structures across the three patents.

What this case signals for the Brazilian automotive anti-theft IP landscape
Three patents across distinct truck subsystems in a single infringement action signals an aggressive, portfolio-based enforcement posture in a specialised niche.
Portfolio bundling amplifies enforcement leverage in niche markets
Asserting three patents across fuel, exhaust fluid, and clutch systems simultaneously suggests Charada Peças is pursuing a portfolio-level exclusion strategy rather than a single-patent dispute. In specialised aftermarket niches like Brazilian heavy-vehicle components, this approach can maximise injunctive pressure and complicate design-around options for competitors.
Interlocutory dismissals do not end Brazilian IP disputes
The dismissal of an interlocutory appeal at the Court of Justice of São Paulo is a procedural milestone, not a final resolution. Companies monitoring this matter — particularly suppliers to fleet operators — should track the first-instance proceedings, where substantive infringement and validity findings will ultimately be made on all three anti-theft lock patents.
EIRELI v GRSUL — key questions answered
The Court of Justice of São Paulo dismissed the interlocutory appeal on 6 February 2024 (Case No. 2.288.122-68.2023.8.26.0000). This is a procedural outcome only — the dismissal addresses a specific interim ruling, not the merits of the underlying patent infringement claims covering the three anti-theft lock patents.
Charada Peças asserted three Brazilian patents: BR102021006825B1 (anti-theft lock for truck liquid reducing agent pump), BR102021002978B1 (anti-theft lock for heavy vehicle fuel tank float), and BR102021023643B1 (anti-theft lock for heavy vehicle clutch servo). All three carry B1 status, indicating INPI examination was completed and claims were granted.
No. An interlocutory appeal dismissal in Brazilian civil procedure resolves only the challenged interim ruling. The underlying infringement action on the merits — covering validity and infringement of all three anti-theft lock patents — is not resolved by this outcome and may still be pending at first instance.
A B1 designation under INPI (Instituto Nacional da Propriedade Industrial) practice indicates that the patent application completed substantive examination and was granted with claims intact. This is distinct from a utility model or unexamined grant, and generally provides stronger presumption of validity in litigation proceedings before Brazilian courts.
An agravo de instrumento is a type of interlocutory appeal in Brazilian civil procedure used to challenge specific interim court orders — such as injunctions, evidence decisions, or preliminary rulings — before a final judgment is rendered. Its admissibility is limited to defined categories of orders. Dismissal typically means the appellate court found the appeal procedurally inadmissible or outside the permitted scope, without ruling on the underlying merits.
