MEI Industrial v. Duravant Brazil: Da Vinci DPM-6000 Deboning Machine Patent Dispute
MEI Industrial Ltda. brought an infringement action against Duravant Brazil Ltda. in the Court of Justice of São Paulo over patent BR112017016154B1, covering the Da Vinci DPM-6000 leg deboning machine. The appellate chamber partially granted the appeal, revoking provisional urgent relief while preserving custody of key documentation.
São Paulo appellate court splits the difference on urgent relief
MEI Industrial Ltda. initiated an infringement action against Duravant Brazil Ltda. before the Court of Justice of São Paulo, asserting patent BR112017016154B1 in connection with the Da Vinci DPM-6000 leg deboning machine — an automated poultry processing system. The case number is 2113584-74.2024.8.26.0000, and the proceedings culminated in an appellate decision closed on 23 October 2024.
On appeal, the court partially granted Duravant Brazil’s challenge to the urgent interim measures previously ordered at pages 258/259 of the original proceeding. The appellate panel revoked the broader urgent relief that had been granted, but critically maintained the custody of documentation that MEI Industrial — referred to as the ‘aggravated parties’ — had requested. This split disposition means neither party obtained a full victory at this appellate stage.
The partial grant of the appeal suggests the court found the lower court’s urgent relief was overly broad, while still recognising the legitimate evidentiary interest in preserving documentation. The public record does not disclose the full scope of the original injunction, the specific infringing acts alleged, or whether merits proceedings continue at first instance. The retention of document custody indicates the underlying dispute remains live and that evidence preservation is considered material to its resolution.

Appeal partially granted: what the São Paulo ruling means for both parties
Partial grant: urgent relief revoked but custody preserved
A partial grant of appeal in Brazilian civil procedure means the appellate chamber agreed with the appellant on some — but not all — grounds. Here, the court revoked the urgent provisional injunction issued at first instance (fls. 258/259), finding it did not meet the full threshold for emergency relief, while nonetheless preserving the order for documentary custody. This is a calibrated procedural outcome, not a merits determination.
Provisional relief modifiedMEI Industrial loses injunction but retains evidentiary protection
As the ‘aggravated parties’ whose urgent relief was largely revoked, MEI Industrial faces a setback in its attempt to immediately restrain Duravant Brazil’s activities. However, the maintained document custody order is a meaningful concession: it preserves evidence that could be pivotal to the merits case. The patent BR112017016154B1 remains in force and the underlying infringement claim has not been adjudicated.
Injunction revoked; evidence preservedDuravant Brazil secures relief from injunction — for now
Duravant Brazil successfully challenged the breadth of the urgent measures, removing the immediate operational constraint imposed by the first-instance court. This restores operational freedom in the short term. However, the continued document custody obligation signals that the court views the underlying dispute as substantive, and Duravant remains exposed to merits proceedings on the BR112017016154B1 infringement claims.
Injunction lifted; merits risk remainsPoultry processing IP enforcement: provisional relief is not a foregone conclusion
This ruling is consistent with a broader pattern in Brazilian IP litigation where appellate courts scrutinise the proportionality of urgent provisional measures. For equipment manufacturers and technology licensors in the food processing sector, it signals that securing and sustaining injunctive relief requires demonstrating both urgency and proportionality. The case also highlights the strategic value of document preservation orders as a fallback enforcement tool.

Official order — verbatim text
The verdict language — ‘PARTIALLY GRANT the appeal to revoke the urgent relief… maintaining only the custody of the documentation’ — reflects a deliberate appellate balancing exercise. The court declined to endorse the full scope of first-instance provisional measures, suggesting the urgency or proportionality threshold was not met for the broader injunction. Crucially, the preservation of document custody indicates the appellate panel recognised an ongoing evidentiary interest, keeping the foundation for merits proceedings intact. This is not a ruling on patent validity or infringement; those questions remain open.
BR112017016154B1 — Da Vinci DPM-6000 automated leg deboning machine
BR112017016154B1 is a Brazilian national phase patent covering technology embodied in the Da Vinci DPM-6000 leg deboning machine — an automated system for mechanical deboning of poultry legs in industrial processing environments. The ‘BR112017016154’ numbering is consistent with a PCT application entering the Brazilian national phase, suggesting international patent family roots. The technology addresses a high-throughput processing challenge in poultry production lines, where automation of the deboning step delivers significant yield and labour efficiency benefits.
In the poultry processing equipment sector, automated deboning represents a technically demanding and commercially high-value niche — making the IP position strategically significant. For equipment manufacturers and food processors operating in Brazil, this patent defines a protected design space around the DPM-6000 architecture. The active enforcement action by MEI Industrial demonstrates willingness to litigate, raising the competitive risk profile for any manufacturer or importer of comparable automated leg deboning systems in the Brazilian market.
Should you run an FTO against BR112017016154B1?
Any manufacturer, distributor, or end-user operating automated poultry leg deboning equipment in Brazil should treat BR112017016154B1 as a live enforcement risk. The active litigation posture of MEI Industrial — including the pursuit of urgent injunctive relief — signals a patent holder prepared to assert its rights aggressively. R&D and procurement teams evaluating the Da Vinci DPM-6000 or comparable leg deboning platforms should commission a freedom-to-operate analysis before commercialisation or import decisions.

What this case signals for food processing equipment IP in Brazil
The São Paulo appellate split decision reflects the calibrated approach Brazilian courts take to urgent IP relief in complex industrial equipment disputes.
Brazilian courts apply proportionality when assessing urgent IP injunctions
The partial revocation of urgent relief in this case suggests that Brazilian appellate courts will scrutinise whether provisional measures are calibrated to the actual risk of harm. Patent holders in the food processing and industrial machinery sectors should build proportionality arguments into their initial applications for interim relief to reduce appellate vulnerability.
Document custody orders are a durable enforcement lever in Brazilian proceedings
Even after the broader injunction was revoked, the court maintained the documentary custody order. This signals that evidence preservation requests are viewed more favourably than operational injunctions at the provisional relief stage — an important tactical consideration for IP enforcement strategy in Brazilian courts.
Ltda. v Duravant — key questions answered
The Court of Justice of São Paulo partially granted Duravant Brazil’s appeal on 23 October 2024. The appellate court revoked the urgent injunctive relief previously granted at first instance (fls. 258/259) but maintained the order for custody of documentation requested by MEI Industrial. The underlying infringement merits were not decided.
BR112017016154B1 is a Brazilian national phase patent covering technology embodied in the Da Vinci DPM-6000 leg deboning machine — an automated poultry processing system. The patent was asserted by MEI Industrial Ltda. in an infringement action against Duravant Brazil Ltda. before the Court of Justice of São Paulo.
The public record indicates only that the appeal was ‘partially granted’ and the urgent relief revoked. The precise reasoning is not disclosed in the available case data. This outcome typically suggests the appellate chamber found the provisional measures did not satisfy the proportionality or urgency threshold required under Brazilian procedural law, though no further detail is publicly confirmed.
The Da Vinci DPM-6000 is an automated leg deboning machine used in industrial poultry processing. It is the product involved in the infringement action brought by MEI Industrial Ltda. against Duravant Brazil Ltda., with MEI Industrial asserting that the machine infringes its patent BR112017016154B1. The case is ongoing at the merits level.
No. The appellate decision concerned only the scope of urgent provisional relief and did not address patent validity or the merits of the infringement claim. Patent BR112017016154B1 remains in force. The document custody order maintained by the court suggests the merits proceedings are expected to continue at first instance.
