Haver & Boecker v. Metso Brasil: Appeal Granted on Mechanical Vibrator Patent
Haver & Boecker Latinoamericana brought a declaratory judgement action against Metso Brasil over patent BR102017026766B1, which covers a mechanical box vibrator for vibrating sieves. The Court of Justice of São Paulo granted the appeal in October 2024, reversing the lower-level determination in Haver & Boecker’s favour.
São Paulo Court overturns lower ruling in vibrating sieve patent dispute
Haver & Boecker Latinoamericana Maquinas Limitada, a machinery supplier active in the Brazilian minerals processing and screening market, initiated a declaratory judgement action against Metso Brasil Indústria and Comércio Ltda, a major industrial equipment manufacturer. The dispute centred on patent BR102017026766B1, which protects a mechanical box vibrator used in vibrating sieves — equipment critical to mineral separation, aggregate screening, and bulk material handling operations.
The Court of Justice of São Paulo granted the appeal filed by Haver & Boecker, closing the case on 8 October 2024. The appellate panel found in favour of the appellant in the terms stated in the ruling, overturning the prior determination. In a declaratory judgement context, this outcome typically suggests the court accepted Haver & Boecker’s position regarding the scope, validity, or enforceability of the patent rights at issue — though the precise terms of the declaration are not fully detailed in the available public record.
The absence of a filed date in the public record makes it difficult to assess the full litigation timeline. The fact that the case reached appellate level before resolution suggests the lower-level decision was contested. What remains unclear from the public record is whether the declaratory relief sought addressed non-infringement, invalidity, or another aspect of the patent right — a distinction that carries materially different commercial consequences for both parties operating in Brazil’s competitive minerals processing equipment sector.

Appeal granted: what the São Paulo ruling means for both parties
What ‘Appeal Granted’ means at this court level
An appeal granted by the Court of Justice of São Paulo means the appellate panel found sufficient legal or factual error in the lower-level determination to reverse it. The court expressly adopted the appellant’s position ‘in the terms mentioned above,’ indicating the relief sought was accepted. This is a substantive appellate victory, not a procedural remand — the lower outcome no longer stands.
Lower decision overturnedHaver & Boecker secures appellate reversal
As the appellant, Haver & Boecker obtained the relief it sought at this appellate stage. In the context of a declaratory judgement action over a mechanical vibrator patent, this outcome is consistent with the court accepting Haver & Boecker’s characterisation of the patent right — whether as to validity, scope, or enforceability. The ruling strengthens Haver & Boecker’s legal position in the Brazilian market for vibrating sieve equipment.
Appellant’s position acceptedMetso Brasil loses appellate challenge
Metso Brasil, as the party defending the lower-level outcome, was unsuccessful at this appellate stage. The reversal means the prior determination in its favour no longer holds. Metso may consider further appeal to a higher tribunal if grounds exist under Brazilian procedural law, though the public record does not indicate any pending proceedings. The commercial impact depends on the precise scope of the declaratory relief granted.
Lower ruling in its favour reversedPatent enforceability in Brazilian screening equipment sector
This outcome suggests BR102017026766B1 retains legal significance in the Brazilian industrial screening market. Competitors and OEM suppliers of mechanical box vibrators and vibrating sieve assemblies operating in Brazil should assess their exposure against this patent in light of the appellate ruling. The decision may also signal the Brazilian judiciary’s willingness to engage substantively with industrial machinery patent disputes at the appellate level.

Official order — verbatim text
The verdict phrase — ‘I GRANT the appeal filed, in the terms mentioned above’ — is a standard Brazilian appellate formulation indicating full acceptance of the appellant’s grounds as argued. It does not specify whether the reversal addresses validity, non-infringement, or another declaratory head, which limits external analysis of precise legal scope. For Haver & Boecker, the ruling reinstates their preferred legal position on patent BR102017026766B1. For Metso Brasil, it nullifies the prior outcome and may require reassessment of product design or licensing posture in the Brazilian market.
BR102017026766B1 — Mechanical Box Vibrator for Vibrating Sieves
BR102017026766B1 protects a mechanical box vibrator designed for use in vibrating sieves — equipment used across minerals processing, aggregate production, and bulk material handling to separate particles by size. The ‘B1’ designation under the Brazilian patent system indicates a granted invention patent that has completed examination. The application number prefix ‘102017’ places the filing in 2017, suggesting the patent reached grant after substantive examination by INPI, Brazil’s national patent office.
Mechanical vibrators are a critical drivetrain component in screening equipment, and proprietary vibrator geometries or bearing configurations can confer measurable performance advantages. In a competitive market where Haver & Boecker and Metso Brasil both supply screening solutions to Brazilian mining and aggregate clients, control over this patent directly affects product differentiation and licensing dynamics. The appellate ruling reinforces the patent’s enforceability and raises the competitive moat around Haver & Boecker’s vibrating sieve product line in Brazil.
Should you run an FTO against BR102017026766B1?
Any company manufacturing, importing, or distributing mechanical box vibrators or vibrating sieve assemblies for the Brazilian market should conduct a freedom-to-operate analysis against BR102017026766B1 following this appellate outcome. The ruling in Haver & Boecker’s favour signals active enforcement intent and a strengthened patent position. R&D teams designing drive units for industrial screening equipment should map their component architecture against the granted claims before commercialisation in Brazil.

Any competitor product that overlaps with the mechanical box vibrator claims should be assessed urgently against the reinstated patent position.
Limitada v Metso — key questions answered
The Court of Justice of São Paulo granted the appeal filed by Haver & Boecker Latinoamericana, closing the case on 8 October 2024. The appellate panel accepted Haver & Boecker’s position in a declaratory judgement action concerning patent BR102017026766B1, which covers a mechanical box vibrator for vibrating sieves, overturning the prior lower-level determination.
BR102017026766B1 is a granted Brazilian invention patent filed in 2017 and assigned to Haver & Boecker Latinoamericana. It protects a mechanical box vibrator used in vibrating sieves — industrial equipment used for particle size separation in minerals processing, aggregate production, and bulk material handling. The ‘B1’ designation confirms it is a fully examined and granted patent under the Brazilian INPI system.
A declaratory judgement action allows a party to seek a court’s formal declaration of legal rights or obligations without waiting for the opposing party to file an infringement suit. In this context, it suggests one party sought judicial clarity on whether the patent is valid, infringed, or enforceable. The public record does not specify the precise declaratory head, but the appellate grant confirms Haver & Boecker’s position was upheld.
The appellate grant strengthens BR102017026766B1’s enforceability in Brazil. Competitors and OEM suppliers of mechanical box vibrators and vibrating sieve components operating in the Brazilian market face elevated freedom-to-operate risk. Companies with products that potentially overlap with the patent’s claims should update their FTO analyses to reflect the post-appeal legal position and consider design-around strategies or licensing approaches.
Under Brazilian procedural law, parties may in principle seek review by the Superior Court of Justice (STJ) on questions of federal law, or the Supreme Court (STF) on constitutional questions, subject to admissibility thresholds. However, the public record for this case does not indicate any pending further appeal. Whether Metso Brasil pursues additional review depends on the specific grounds available and commercial considerations not visible in the current record.
