Santos v. Tekal Equipamentos: Interlocutory Appeal Granted on Oscillating Feed Patent
Jose Francisco dos Santos brought a patent dispute against Tekal Equipamentos para Avicultura Ltda Epp before the Court of Justice of São Paulo, asserting utility model patent BRMU9101946U2 covering an arrangement for an oscillating metering feed system used in poultry farming equipment. The Court granted the interlocutory appeal, closing the case on 18 February 2025.
São Paulo appellate court grants interlocutory appeal in poultry feed patent row
Jose Francisco dos Santos, holder of Brazilian utility model BRMU9101946U2, initiated proceedings against Tekal Equipamentos para Avicultura Ltda Epp, a company operating in the poultry equipment sector. The patent at issue covers an arrangement for an oscillating metering feed system — technology relevant to automated feed distribution in aviculture. The case was filed and adjudicated before the Court of Justice of São Paulo, one of Brazil’s principal state-level appellate courts.
The case closed on 18 February 2025 following the Court’s decision to grant an interlocutory appeal. In Brazilian civil procedure, an interlocutory appeal (agravo regimental or agravo de instrumento) challenges an interim ruling rather than a final judgment on the merits, and its grant signals that the appellate panel found procedural or substantive error in the lower-level decision being challenged. The basis of termination is recorded as ‘Appeal Granted’, consistent with this procedural posture.
Because the filing date and full duration are not available in the public record, it is not possible to assess the overall litigation timeline against Brazilian court benchmarks. The grant of an interlocutory appeal suggests the proceedings may continue at the trial level following this ruling, though the public record does not disclose what further relief or remand instructions, if any, accompanied the decision. The absence of a costs ruling and agent details limits further public analysis of the commercial stakes involved.

Interlocutory appeal granted: what the ruling means for both parties
What ‘appeal granted’ means in Brazilian civil procedure
In Brazilian procedural law, granting an interlocutory appeal means the appellate court found reversible error in an interim ruling made below. It does not necessarily resolve the merits of the patent dispute; instead, it corrects a procedural or substantive step. The underlying patent infringement or validity questions typically return to the lower court for further proceedings unless the appellate decision fully disposes of the issue.
Procedural correction — not a final merits rulingAppeal grant may revive or advance Santos’s claim
If it was Santos who lodged the interlocutory appeal — which the ‘Appeal Granted’ termination basis suggests is consistent with — the ruling represents a procedural win. The lower court decision he challenged has been set aside or modified. However, the public record does not confirm whether this fully vindicates his patent position or merely reopens the proceedings at a prior stage.
Possible procedural advantage for patent holderTekal faces continuation of proceedings following reversal
For Tekal Equipamentos, the grant of the interlocutory appeal suggests an interim ruling in their favour below has been disturbed. The poultry equipment maker now faces the prospect of continued litigation exposure over the oscillating metering feed arrangement. The extent of that exposure depends on the scope of the appellate court’s instructions, which are not fully disclosed in the available public record.
Litigation exposure continues for defendantUtility model enforcement in Brazil’s agri-equipment sector
This case illustrates that Brazilian utility model patents covering agricultural and poultry equipment remain actively enforced before state appellate courts. For competitors in the aviculture equipment space, the willingness of individual inventors to pursue interlocutory appeals signals committed enforcement postures. Companies sourcing or manufacturing oscillating feed metering technology in Brazil should assess freedom-to-operate exposure against BRMU9101946U2.

Official order — verbatim text
The court’s disposition — ‘the interlocutory appeal is granted, with observation’ — is a procedural ruling rather than a final determination on the merits of the patent dispute. The phrase ‘with observation’ (com observação) in Brazilian appellate practice typically signals that the court attaches qualifying remarks or conditions to the grant, though the specific content is not disclosed in the available record. The ruling does not resolve patent validity or infringement but disturbs the challenged interim decision below.
BRMU9101946U2 — Oscillating Metering Feed Arrangement for Poultry Equipment
BRMU9101946U2 is a Brazilian utility model patent covering an arrangement for an oscillating metering feed system, applied in aviculture (poultry farming) equipment. Brazilian utility models protect functional innovations in the form or structure of objects of practical use, requiring a lower inventive step threshold than invention patents but providing up to 15 years of protection. The patent is registered under application number BRMU9101946U2, indicating an early-1990s application date, suggesting a long-standing proprietary position in this segment of agricultural equipment.
Oscillating metering feed arrangements are a core mechanical component in automated poultry farming systems, controlling the precise dosing and distribution of feed. As Brazilian agribusiness and aviculture have grown into globally significant industries, the mechanical IP underpinning automated farm equipment has become increasingly contested. Competitors developing or sourcing feed metering technology for the Brazilian market — particularly those supplying integrated poultry operations — face meaningful infringement risk if their products fall within the functional scope of this utility model.
Should you run an FTO analysis against BRMU9101946U2?
Any company designing, manufacturing, importing, or distributing oscillating or reciprocating metering feed equipment for poultry applications in Brazil should treat BRMU9101946U2 as a priority clearance target. The active appellate enforcement of this utility model — and the Court of Justice of São Paulo’s decision to grant the interlocutory appeal — confirms the patent holder’s intent to defend the right aggressively. This is particularly relevant for equipment integrators supplying large-scale Brazilian poultry operations.
PatSnap Eureka’s FTO Search Agent can map the claim scope of BRMU9101946U2 against your product architecture, surface prior art that may support a validity challenge, and identify design-around opportunities. Given the utility model’s long filing history, a thorough prior art landscape search may also reveal opportunities to narrow or contest the enforceable scope of the right if litigation risk materialises.

What this case signals for the Brazilian agri-equipment IP landscape
Individual utility model holders in Brazil’s poultry equipment sector are demonstrating willingness to pursue multi-stage appellate enforcement strategies.
Brazilian utility models carry real appellate enforcement weight
This case confirms that utility model rights in Brazil — often perceived as lower-tier IP — are being actively enforced through the full appellate hierarchy at the Court of Justice of São Paulo. Companies in the aviculture and agri-equipment sector should not dismiss utility model clearance as a low-priority step.
Interlocutory appeals can reset the litigation clock for patent holders
The grant of an interlocutory appeal can effectively undo favourable interim rulings for defendants, resetting proceedings at an earlier stage. For equipment manufacturers operating in Brazil, this procedural mechanism means that a win at first instance may not provide durable protection against a determined patent holder.
Santos v Tekal — key questions answered
The Court of Justice of São Paulo granted the interlocutory appeal on 18 February 2025, closing the case. The basis of termination is recorded as ‘Appeal Granted’. This is a procedural ruling that disturbs an interim decision below; it does not constitute a final merits judgment on the underlying patent infringement or validity dispute.
BRMU9101946U2 is a Brazilian utility model patent held by Jose Francisco dos Santos. It covers an arrangement for an oscillating metering feed system used in poultry farming (aviculture) equipment. Brazilian utility models protect practical functional innovations and can provide up to 15 years of protection from filing.
In Brazilian civil procedure, an interlocutory appeal (typically an agravo de instrumento) challenges an interim ruling rather than a final judgment. When granted, it signals the appellate court found error in that interim decision. The underlying dispute typically continues at the lower court level unless the appellate ruling fully disposes of the matter.
The public record does not disclose any ruling on the validity of BRMU9101946U2. The case was resolved on procedural grounds via an interlocutory appeal. There is no indication from this case alone that the utility model has been invalidated or limited. Companies with potential exposure should conduct an independent FTO and validity analysis.
Tekal Equipamentos para Avicultura Ltda Epp operates in the Brazilian poultry farming (avicultura) equipment sector. The company’s name indicates it manufactures or supplies equipment for aviculture operations. The patent dispute concerns oscillating metering feed arrangement technology, a mechanical component used in automated poultry feed distribution systems.
