Dyna Indústria v. Valeo Sistemas Automotivos — Appeal Dismissed in Wiper Blade Packaging IP Dispute
Brazilian automotive supplier Dyna Indústria brought an infringement action against Valeo Sistemas Automotivos over two patents protecting wiper blade packaging technology. The São Paulo Court of Justice closed the case on 6 February 2024 by dismissing Valeo’s appeal, affirming the lower court’s position across two distinct patent rights.
Appeal defeat for Valeo in São Paulo wiper blade packaging IP clash
Dyna Indústria e Comércio Ltda, a Brazilian industrial manufacturer, brought an infringement action before the São Paulo courts against Valeo Sistemas Automotivos Ltda, a local subsidiary of the global Tier 1 automotive supplier Valeo. The dispute centred on two Brazilian intellectual property rights: patent BRPI0414371B1 and utility model BRMU1211785U2, both covering packaging arrangements for flat or arched wiper blades with integrated flexible structures — a niche but commercially significant segment of the aftermarket automotive parts supply chain.
The case progressed to the appellate level at the Court of Justice of São Paulo (Tribunal de Justiça do Estado de São Paulo), where the appeal lodged by Valeo Sistemas Automotivos was dismissed. The basis of termination recorded as ‘Appeal Dismissed’ indicates the appellate panel declined to overturn the lower court’s findings, leaving the infringement determination against Valeo in place. This outcome is consistent with the lower court having found infringement of one or both of Dyna’s asserted rights, though the specific relief granted — injunctive or monetary — is not fully detailed in the available public record.
The case reached closure on 6 February 2024, though the original filing date is not publicly recorded, making precise duration analysis unavailable. The fact that the dispute reached the appellate level before final resolution suggests meaningful commercial stakes for both parties in the wiper blade packaging category. What remains unknown from the public record is whether damages were quantified, whether an injunction was ordered against Valeo’s products, and whether further extraordinary appeal mechanisms — such as a Special Appeal to the Superior Tribunal de Justiça — were or may still be pursued.

What the dismissal of Valeo’s appeal means for both parties
Appeal dismissed — lower court ruling stands
When an appellate court dismisses an appeal, it affirms the decision reached below without substituting its own judgment on the merits. For Dyna Indústria, this is a favourable conclusion: the infringement finding it obtained at first instance has survived judicial scrutiny at the next level. For Valeo, the dismissal means the adverse ruling remains in force and enforceable. The specific relief — damages, royalties, or injunction — would have been determined by the lower court.
Infringement affirmed on appealTwo distinct IP instruments asserted simultaneously
Dyna asserted both a patent (BRPI0414371B1) and a utility model (BRMU1211785U2). In Brazilian IP law, these are separate instruments: patents protect inventions with inventive step, while utility models — with a lower inventive threshold — protect functional improvements to objects. Asserting both broadens coverage and complicates a defendant’s invalidity strategy, since each right must be challenged independently. The survival of both rights through appeal strengthens Dyna’s portfolio position considerably.
Patent + utility model dual assertionSão Paulo appellate court: key venue for Brazilian IP disputes
The Court of Justice of São Paulo (TJSP) handles a large share of Brazilian IP litigation given the state’s concentration of automotive and industrial activity. An appeal dismissal at the TJSP level is a significant outcome, though Brazilian civil procedure does permit further extraordinary appeals to the Superior Tribunal de Justiça (STJ) on points of federal law. Whether Valeo pursues that route is not reflected in this case record and would represent a separate procedural stage.
TJSP — Brazil’s primary IP appellate venueWiper blade packaging: niche IP with real aftermarket value
Packaging for flat and arched wiper blades — particularly designs with integrated flexible structures — is commercially relevant in the automotive aftermarket, where product presentation, protection during distribution, and shelf differentiation drive purchasing decisions. A ruling that locks in IP protection over such packaging can restrict how competitors package comparable products. For a Tier 1 supplier like Valeo, adverse IP outcomes in packaging design can affect distribution and retail strategy across multiple markets.

Stipulation of dismissal — official text
The appellate court’s dismissal of Valeo’s appeal — recorded as ‘the appeal is dismissed’ — affirms the lower court’s infringement determination without modification. This phrasing is consistent with the panel finding no reversible error in the trial court’s analysis of either BRPI0414371B1 or BRMU1211785U2. For Dyna, the ruling consolidates its IP position. For Valeo, it removes the appellate shield and leaves any enforcement orders from below fully operative, subject only to any extraordinary appeal mechanisms available under Brazilian procedural law.
BRPI0414371B1 & BRMU1211785U2 — Wiper Blade Packaging Technology
BRPI0414371B1 is a Brazilian patent protecting an arrangement introduced in packaging for reed or wiper blade components. BRMU1211785U2 is a Brazilian utility model covering a specific packing device for wiper brush assemblies incorporating an arched blade and an integrated flexible structure — a design feature relevant to flat and hybrid wiper blade formats that have grown in market share over conventional frames. Both rights are held by Dyna Indústria e Comércio Ltda and were asserted concurrently in this infringement action, targeting Valeo’s wiper blade packaging practices in the Brazilian market.
The strategic value of these two IP instruments lies in their combined coverage of a commercially active product category. Wiper blade packaging — particularly for arched and flat blade formats — is a recurring point of differentiation in the automotive aftermarket, where retail visibility and packaging integrity influence consumer and distributor choices. A utility model such as BRMU1211785U2 typically attracts a lower inventive step threshold under Brazilian IP law (Lei 9.279/96), making it harder to invalidate while still conferring enforceable exclusive rights. For competitors and new entrants in Brazil’s automotive aftermarket, these rights represent a meaningful design-around challenge.
Should you run an FTO against BRPI0414371B1 and BRMU1211785U2?
Any company manufacturing, importing, or distributing wiper blade products — or similar reed-type component packaging — in Brazil should treat these two rights as active clearance items. The successful enforcement against Valeo, a global Tier 1 supplier, confirms Dyna’s willingness to litigate and the courts’ readiness to uphold these rights. This applies equally to OEM packaging suppliers, aftermarket distributors, and private-label retailers operating in the Brazilian automotive segment.

What this case signals for the Brazilian automotive aftermarket IP landscape
A smaller Brazilian supplier successfully defending packaging IP against a global Tier 1 — and winning on appeal — signals that domestic patent rights carry real enforcement weight in Brazil.
Brazilian utility models are enforceable tools against large competitors
Dyna’s dual assertion of a patent and a utility model against a Tier 1 automotive group — and prevailing at the appellate level — demonstrates that Brazilian utility models (BRMU) are not merely defensive filings. Companies operating in Brazil should audit competitor utility model portfolios with the same rigour applied to standard patents, particularly in product packaging and functional design categories.
Wiper blade IP is an underappreciated enforcement domain
This case joins a small but growing body of Brazilian IP enforcement actions targeting automotive aftermarket products. Packaging innovations — often considered secondary to core mechanical patents — are demonstrably litigable and worth protecting. R&D and IP teams developing aftermarket packaging for wiper systems, filters, or similar components should run FTO searches that specifically include utility model registers in Brazil and comparable MERCOSUL jurisdictions.
DYNA v VALEO — key questions answered
The Court of Justice of São Paulo dismissed Valeo Sistemas Automotivos’ appeal, affirming the lower court’s ruling in favour of Dyna Indústria. The case was closed on 6 February 2024. Dyna had asserted two Brazilian IP rights — patent BRPI0414371B1 and utility model BRMU1211785U2 — covering wiper blade packaging arrangements.
Dyna Indústria asserted two Brazilian intellectual property rights: BRPI0414371B1, a patent covering an arrangement in reed/wiper blade packaging, and BRMU1211785U2, a utility model protecting a packing device for wiper brushes with an arched blade and integrated flexible structure. Both rights were asserted simultaneously in the same infringement action.
Under Brazilian IP law (Lei 9.279/96), a utility model (modelo de utilidade) protects a functional improvement to an object or tool. It requires a lower inventive step than a standard patent, has a protection term of 15 years from filing, and is generally more difficult to invalidate on grounds of obviousness. In this case, BRMU1211785U2 provided Dyna with a separate enforceable right alongside the full patent BRPI0414371B1.
In Brazilian civil procedure, dismissal of an appeal by the Court of Justice (TJSP) means the appellate panel found no reversible error in the lower court’s decision and affirmed it in full. The infringement finding against Valeo therefore stands. Further extraordinary appeal to the Superior Tribunal de Justiça (STJ) on federal law grounds is technically available but represents a separate and more limited procedural route.
Yes. The successful enforcement of BRPI0414371B1 and BRMU1211785U2 against Valeo Sistemas Automotivos — a global Tier 1 supplier — confirms these rights are actively enforced and judicially upheld. Any company manufacturing, importing, distributing, or packaging wiper blade products in Brazil should conduct an FTO analysis against both rights before market entry or product redesign to assess claim overlap and design-around options.
