Mei Industrial v. Foodmate B.V: Patent Invalidity Appeal Dismissed in São Paulo
Mei Industrial Ltda challenged the validity of Foodmate B.V’s Brazilian patent BR112017016154B1, covering automated devices for producing preparatory incisions along animal limb joints in meat processing lines. The Court of Justice of São Paulo dismissed the interlocutory appeal on 30 April 2025, leaving the underlying cancellation action to proceed without the interim relief sought.
Invalidity challenge stalls at interlocutory stage in São Paulo
Mei Industrial Ltda, a Brazilian industrial entity, brought an invalidity and cancellation action against Foodmate B.V, a Dutch meat processing equipment manufacturer, targeting Brazilian patent BR112017016154B1. The patent in dispute covers a device designed to make a preparatory longitudinal incision along the end part of a slaughtered animal where two bones are articulated by a joint — a core automation step in modern poultry and meat processing lines. The action was filed before the Court of Justice of São Paulo.
The proceeding closed on 30 April 2025 when the court dismissed an interlocutory appeal brought within the broader invalidity action. Dismissal of an interlocutory appeal is a procedural outcome: the court declined to grant the interim relief or procedural ruling sought mid-case, without adjudicating the underlying merits of the validity challenge. Foodmate’s patent therefore retains its registered status in Brazil, and the substantive cancellation proceedings may continue at the trial level.
Because no filing date is available in the public record, the total duration of the dispute cannot be calculated. The dismissal at the interlocutory stage suggests the challenger did not satisfy the threshold requirements for interim appellate intervention — typically urgency and a strong prima facie case. What remains unresolved from public filings is whether the underlying invalidity/cancellation action itself remains active or has been separately concluded.

Interlocutory appeal dismissed: what this procedural ruling means for both parties
What an interlocutory appeal dismissal actually means
An interlocutory appeal targets a specific procedural or interim ruling made during ongoing litigation — not the final decision on the merits. Its dismissal means the appellate court found the appeal inadmissible or unmeritorious at this procedural stage. Critically, it does not constitute a ruling on whether BR112017016154B1 is valid or invalid. The substantive invalidity/cancellation action may continue independently before the lower court.
No merits ruling on validityMei Industrial loses interim appellate foothold
For Mei Industrial, dismissal of the interlocutory appeal means the interim procedural relief it sought has been denied. The challenger did not secure a favourable mid-case ruling that could have altered the trajectory of the invalidity action. However, this outcome does not foreclose Mei Industrial from continuing to pursue the underlying cancellation on the merits — that substantive question remains open unless separately resolved.
Interim relief deniedFoodmate’s Brazilian patent survives this procedural challenge
Foodmate B.V retains the registered status of BR112017016154B1 in Brazil following dismissal of the interlocutory appeal. The patent covering its automated joint incision technology remains enforceable for the time being. Foodmate is not yet clear of the broader invalidity action, however — the dismissal is a procedural win, not a definitive confirmation of the patent’s validity on the merits.
Patent status maintainedUncertainty remains for meat processing equipment competitors in Brazil
For companies operating or supplying automated meat processing equipment in Brazil, BR112017016154B1 continues to represent an active IP risk. The dismissal of the interlocutory appeal does not resolve the underlying validity question. Competitors and licensees should monitor the progression of the main cancellation action and consider freedom-to-operate analysis before commercialising related joint incision automation technology in the Brazilian market.

Official order — verbatim text
The court’s ruling — ‘the interlocutory appeal is dismissed’ — is a purely procedural disposition. It reflects that the appellate panel found the interim appeal inadmissible or without sufficient grounds to intervene at this mid-case stage. No finding was made on the substantive validity of BR112017016154B1. Under Brazilian civil procedure, interlocutory appeals (agravo de instrumento) face strict admissibility requirements; dismissal suggests those thresholds were not met. The underlying invalidity/cancellation action is unaffected on the merits by this ruling.
BR112017016154B1 — Automated animal joint longitudinal incision device
BR112017016154B1 is a Brazilian national phase patent derived from a PCT application. It protects a device, equipment system, and method for automatically producing a longitudinal preparatory incision along the end part of a slaughtered animal’s limb, specifically where two bones — such as the tibia and fibula or equivalent joint structures — are articulated by a joint. This technology addresses a precise and repeatable cutting step that is critical to automated deboning and portioning in industrial meat processing facilities.
Foodmate B.V, headquartered in the Netherlands, is a recognised supplier of poultry and meat processing automation equipment globally. A Brazilian patent in this technical area represents a meaningful competitive barrier for any local or international competitor seeking to sell or operate similar joint incision automation systems in Brazil — one of the world’s largest meat producing and exporting markets. The pending invalidity action filed by Mei Industrial underscores the commercial stakes attached to this registration.
Should you run an FTO against BR112017016154B1?
Any company developing, importing, or commercialising automated meat processing equipment — particularly devices involving longitudinal cutting of jointed animal limbs — in Brazil should treat BR112017016154B1 as an active FTO concern. The patent remains in force while the invalidity challenge is unresolved. Equipment suppliers, system integrators, and poultry plant operators deploying automated joint incision technology face direct infringement risk if their systems overlap with the patent’s claim scope.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map claim scope against their specific product architecture, identify relevant prior art across PCT, INPI, and EPO databases, and track the live status of BR112017016154B1 and any related family members. Given the dual-track nature of Brazilian IP disputes — court and INPI administrative channels — continuous monitoring is as important as the initial FTO clearance exercise.

What this case signals for the meat processing equipment IP landscape in Brazil
A procedural dismissal in São Paulo leaves Foodmate’s automation patent intact — but the validity question is unresolved and commercially significant.
Brazilian invalidity actions often extend beyond interlocutory skirmishes
The dismissal of an interlocutory appeal in a Brazilian invalidity action typically signals that the main cancellation proceeding continues at trial level. Competitors should not interpret this outcome as a final determination of patent strength. Monitoring the underlying INPI administrative record and São Paulo court docket is essential for anyone assessing freedom-to-operate in automated meat processing.
Foodmate’s patent covers a commercially critical automation step
BR112017016154B1 targets the longitudinal joint incision stage — a high-value automation step in poultry and red meat deboning lines. Any manufacturer integrating automated limb-end processing equipment in Brazil should conduct FTO analysis against this patent, regardless of the current procedural outcome. Enforceability in Brazil is maintained while the validity challenge is unresolved.
Ltda v Foodmate — key questions answered
The Court of Justice of São Paulo dismissed an interlocutory appeal filed by Mei Industrial Ltda on 30 April 2025. This was a procedural dismissal — no ruling was made on the underlying merits of the invalidity/cancellation action targeting Foodmate’s patent BR112017016154B1. The patent retains its registered status in Brazil.
BR112017016154B1 covers a device, meat processing equipment system, and method for automatically producing a longitudinal preparatory incision along the end part of a slaughtered animal where two bones are connected by a joint — a key automation step in industrial poultry and meat deboning operations. The patent is held by Dutch company Foodmate B.V.
No. Dismissal of an interlocutory appeal in Brazilian proceedings is a procedural outcome only — it means the interim appellate relief was denied, not that the patent has been found valid on the merits. The substantive invalidity/cancellation action may continue at first instance before the São Paulo courts or through INPI administrative channels.
In Brazilian civil procedure, an interlocutory appeal (agravo de instrumento) is a mechanism to challenge a specific interim or procedural ruling made during ongoing litigation — it does not appeal the final decision. Courts impose strict admissibility requirements including urgency. Dismissal suggests the panel found those requirements unmet, leaving the main action to proceed on its original course.
Yes. BR112017016154B1 remains in force in Brazil while the invalidity challenge is unresolved. Any company supplying or operating automated joint incision or deboning equipment in Brazil should conduct a freedom-to-operate analysis against this patent’s claims. Brazil is a major global meat producer, making this patent commercially significant for international equipment suppliers targeting that market.
