Marchesan v. Stara: Agricultural Bulk Cart Patent Appeal Partly Upheld
Marchesan Implementos e Máquinas Agrícolas Tatú S/A brought a patent infringement action against rival agricultural equipment maker Stara S/A over BRMU8101913U, a utility model patent covering a bulk cart for agricultural supply. The Court of Justice of São Paulo partly granted the appeal, resulting in a split outcome for both parties.
Brazilian agricultural equipment rivals clash over bulk cart utility model
Marchesan Implementos e Máquinas Agrícolas Tatú S/A, a Brazilian manufacturer of agricultural implements, brought a patent infringement action against Stara S/A Indústria de Implementos Agrícolas — a competing producer of agricultural equipment — before the Court of Justice of São Paulo (Case No. 2331134-35.2023.8.26.0000). The dispute centres on BRMU8101913U, a Brazilian utility model patent protecting a ‘cart graneleira’ (bulk supply cart) used in agricultural supply operations.
The case was resolved at the appellate level on 29 May 2024, with the court partly granting the appeal. Rapporteur Desembargador Grava Brazil, sitting as 2nd Judge, delivered the deciding vote. A partial grant at this level suggests the court found merit in some — but not all — of the appellant’s arguments, meaning neither party achieved a full victory. The specific scope of what was upheld and what was denied is not fully detailed in the available public record.
The absence of a filing date in the public record makes it difficult to assess the full duration of this litigation. The partial nature of the outcome is notable: it typically signals either a mixed finding on infringement and remedies, or that certain claims were sustained while others failed. What drove the partial grant — whether scope of claims, validity of the utility model, or specific infringing acts — remains unclear from available records and would require review of the full judgment text.

Appeal partly granted: what the São Paulo ruling means for both parties
What ‘Appeal Granted In Part’ means in Brazilian IP litigation
A partial grant of appeal (‘provimento em parte’) at the Court of Justice of São Paulo means the appellate panel found reversible error in some aspects of the lower court’s decision, but not all. The court upheld portions of the appeal while rejecting others, producing a hybrid outcome. This is distinct from a full reversal or a full affirmance — it typically results in a modified lower court decision or a remand on specific points.
Partial appellate reliefMarchesan secures partial vindication on infringement claims
As the party that filed the underlying infringement action, Marchesan’s appeal being partly granted suggests the court found at least some of its arguments meritorious — potentially reinstating or expanding relief denied below. However, the partial nature means Marchesan did not prevail on all grounds pursued, limiting the full protective and commercial effect it sought for patent BRMU8101913U.
Partial plaintiff winStara avoids a complete adverse ruling but faces residual exposure
Stara S/A’s position is nuanced: the rejection of part of Marchesan’s appeal provides some protection. However, the portions of the appeal that were upheld likely impose obligations — potentially injunctive relief or damages — on Stara in relation to the bulk cart product. Stara’s continued commercialisation of the disputed product may now be subject to conditions or restrictions flowing from the partial determination.
Partial adverse findingMixed ruling keeps IP risk alive in the Brazilian agri-equipment sector
A partial appellate grant in a Brazilian utility model infringement case signals that courts will scrutinise product design in the agricultural supply machinery space. Competitors developing bulk cart or graneleira-type products should treat BRMU8101913U as an active enforcement risk. The split outcome may invite further legal proceedings on unresolved points, prolonging commercial uncertainty for both Stara and market entrants in similar product categories.

Official order — verbatim text
The verdict text — ‘upheld in part to the appeal, with determination’ — is characteristic of a Brazilian appellate partial provimento. It confirms the Court of Justice of São Paulo did not simply affirm or reverse the lower court wholesale, but instead modified the outcome in a targeted way. The phrase ‘with determination’ (com determinação) typically signals a specific directive to the lower court or parties. The scope of what was upheld versus rejected is not specified in the available extract, which limits external assessment of the precise legal and commercial impact on each party.
BRMU8101913U — bulk supply cart for agricultural machinery
BRMU8101913U is a Brazilian utility model registration (registro de modelo de utilidade) protecting a ‘cart graneleira’ — a bulk supply cart used in agricultural field operations, typically for transferring grain or seed to seeding or fertilising machinery. Utility models in Brazil protect ornamental or functional improvements to existing objects and are granted for a maximum of 15 years from filing. The ‘MU’ prefix and ‘8101913’ numbering suggest this is an established registration with a filing history predating the litigation.
In the context of Brazilian agribusiness — one of the world’s largest agricultural markets — supply chain equipment like bulk carts is commercially significant. Protecting specific cart architectures through utility models is a recognised competitive strategy among implement manufacturers. BRMU8101913U represents a potential chokepoint for competitors designing similar supply cart products, particularly in the planting and fertilisation machinery segment where Marchesan and Stara both compete directly.
Should you run an FTO against BRMU8101913U?
Any manufacturer, distributor, or importer of bulk supply carts (cart graneleira) for agricultural use in Brazil should treat BRMU8101913U as a live clearance risk following this appellate ruling. The partial grant signals the patent’s enforceability has been confirmed at least in part by the São Paulo Court of Justice. R&D teams designing supply cart architectures — particularly those targeting the Brazilian market — should assess their designs against the registered claims before commercialisation.

What this case signals for the Brazilian agricultural equipment IP landscape
A partly upheld infringement appeal over a utility model reinforces that Brazilian courts will engage substantively with agricultural implement patent claims.
Utility model patents in Brazil carry real enforcement teeth
BRMU8101913U is a utility model (modelo de utilidade), which in Brazil grants protection for functional improvements to existing products. This case demonstrates that utility models — often underestimated relative to invention patents — can support successful appellate enforcement in the Court of Justice of São Paulo. Agricultural equipment firms should audit competitor utility model portfolios proactively.
Partial outcomes create lasting commercial ambiguity for both sides
A split appellate decision rarely resolves underlying commercial tensions. For Stara, partial adverse findings may restrict product lines or trigger damages calculations. For Marchesan, unconceded grounds may invite further proceedings. IP teams monitoring the Brazilian agri-equipment space should track any subsequent lower court proceedings flowing from this determination.
S/A v Stara — key questions answered
The Court of Justice of São Paulo partly granted the appeal filed in this infringement action on 29 May 2024. Rapporteur Des. Grava Brazil delivered the deciding vote upholding the appeal in part with a specific determination, meaning neither party achieved a complete victory at the appellate level.
The patent at issue is BRMU8101913U, a Brazilian utility model registration covering a ‘cart graneleira’ (bulk supply cart) for agricultural operations. Utility models in Brazil protect functional improvements to products and provide up to 15 years of protection from the filing date.
In Brazilian procedural law, ‘provimento em parte’ (appeal granted in part) at the Court of Justice level means the appellate panel found merit in some — but not all — of the appellant’s grounds. The lower court’s decision is modified in specific respects while being maintained in others, producing a split outcome that may include a directive to the lower court.
Marchesan Implementos e Máquinas Agrícolas Tatú S/A and Stara S/A Indústria de Implementos Agrícolas are both established Brazilian manufacturers of agricultural implements. They compete directly in the seeding, fertilising, and supply machinery segments of one of the world’s largest agricultural equipment markets.
The partial appellate grant suggests BRMU8101913U retains enforceable scope. Competitors commercialising bulk supply cart or graneleira-type products in Brazil should conduct freedom-to-operate clearance against this utility model before market entry. The ruling raises infringement risk for products with similar architectural features to those protected under the registration.
