Mavind v. Elias Francisco da Silva: Conveyor Guard Patent Appeal Granted
Mavind Indústria de Máquinas e Equipamentos Ltda pursued an infringement action against Elias Francisco da Silva over Brazilian patent BRPI1003853B1, covering guard assembly conveyors. The Court of Justice of São Paulo granted the appeal, ruling that expert evidence costs fall entirely on the aggrieved party — a procedural outcome with direct implications for cost allocation in Brazilian IP disputes.
São Paulo appellate court reallocates expert costs in conveyor patent dispute
Mavind Indústria de Máquinas e Equipamentos Ltda, the plaintiff and holder of Brazilian patent BRPI1003853B1 relating to guard assembly conveyors, brought an infringement action against individual defendant Elias Francisco da Silva before the Court of Justice of São Paulo. The case centred on alleged unauthorised use of patented mechanical guarding technology for conveyor systems — an industrial safety segment where proprietary designs carry meaningful commercial value.
The appeal was granted on a discrete but consequential procedural issue: the apportionment of expert witness fees. The original decision had divided expert costs between the parties; the appellate court overturned that allocation, determining that because only the aggrieved party (Mavind) maintained its interest in producing expert evidence, the full cost of that expert engagement should fall on that party alone. The ruling does not appear from the public record to resolve the underlying infringement merits.
The outcome is consistent with Brazilian civil procedure principles that link cost liability to the party that benefits from or necessitates a procedural step. The absence of a filing date in the public docket limits duration analysis. What remains unclear from the publicly available record is whether the underlying infringement claim has been separately adjudicated or remains pending, and whether the cost ruling was contested further.

Appeal granted: what the cost reallocation ruling means for both parties
Appeal granted on expert fee apportionment — not merits
The São Paulo Court of Justice granted the appeal on a procedural cost question: whether expert witness fees should be split or borne by one party. Under Brazilian civil procedure, cost allocation follows interest — the court found that only Mavind pressed for expert evidence, making it the cost-bearer. This is a narrow appellate win that corrects the lower court’s cost split but does not, on the face of the record, decide the infringement claim.
Procedural cost rulingMavind wins the appeal but absorbs full expert costs
Although the appeal was granted in Mavind’s favour procedurally, the practical result is that Mavind bears the entire expert witness fee — because it was Mavind that sustained interest in the expert evidence production. This is a mixed outcome: the lower court’s apportionment is corrected, but Mavind assumes a potentially significant cost burden that had previously been shared.
Cost burden on plaintiffSilva relieved of expert fee share under appellate ruling
Elias Francisco da Silva benefits from the appellate ruling insofar as the share of expert costs previously assigned to the defendant is removed. The defendant’s position on the underlying infringement allegation is not resolved by this ruling based on the available public record. The cost relief is a concrete procedural gain for the defendant regardless of any future merits determination.
Defendant cost reliefCost-bearing rules shape enforcement strategy in Brazilian IP cases
This ruling is a reminder that in Brazilian patent enforcement, the procedural costs of expert evidence can be substantial and are tightly linked to which party drives the evidentiary process. Patent holders in Brazil considering expert-heavy infringement claims should model expert fee exposure carefully. The decision suggests that maintaining exclusive interest in an expert report consolidates cost liability on the requesting party.

Official order — verbatim text
The appellate ruling is confined to the procedural question of expert fee apportionment. The court’s reasoning — that only the aggrieved party maintained interest in producing expert evidence — reflects a well-established principle in Brazilian civil procedure linking cost liability to procedural benefit. The verdict does not appear to address the substantive infringement allegations under BRPI1003853B1. Practitioners should note that this outcome leaves the merits of the conveyor guard patent dispute unresolved on the face of the public record, and the cost ruling may itself influence whether either party pursues further proceedings.
BRPI1003853B1 — guard assembly conveyors, mechanical safety guarding
BRPI1003853B1 is a Brazilian granted patent (granted patent number prefix ‘B1’ indicates examination and grant) covering guard assembly conveyors — mechanical safety guarding structures designed to protect operators and equipment in industrial conveyor systems. Conveyor guard assemblies are a regulated safety category in manufacturing and logistics environments, making proprietary designs commercially significant and defensible against copying by smaller operators or component suppliers.
For Mavind, a machinery and equipment manufacturer, this patent represents a defensible product differentiation in the Brazilian industrial safety equipment market. Competitors or individual manufacturers offering similar guarding solutions for conveyor lines face potential infringement exposure. The case against an individual defendant suggests the alleged infringement may relate to a localised manufacturing or supply arrangement rather than a large-scale commercial operation — but the patent’s granted status gives Mavind broad enforcement standing across Brazil.
Should you run an FTO against BRPI1003853B1?
Any R&D team or manufacturer developing guard assembly solutions for conveyor systems in Brazil should assess freedom-to-operate against BRPI1003853B1. The patent’s granted status and active enforcement history — including this appellate proceeding — confirm Mavind’s willingness to pursue infringement claims. Companies supplying conveyor safety guarding to Brazilian industrial customers, or importing equivalent assemblies, should treat this patent as a live clearance consideration.

What this case signals for the industrial machinery IP landscape in Brazil
Cost allocation in Brazilian patent litigation is a strategic lever — this ruling illustrates how appellate courts apply it in contested infringement cases.
Expert cost exposure is a real enforcement risk in Brazilian IP disputes
Brazilian civil procedure ties expert fee liability to the party that maintains procedural interest in the evidence. Patent holders pursuing infringement actions through expert-heavy routes should budget for full expert cost exposure if the defendant withdraws from the evidentiary process — as this case demonstrates.
Narrow appellate wins on procedure can reshape overall case economics
Even when an infringement merits decision is not reached, appellate rulings on cost apportionment can materially affect the economic calculus for both sides. Rights holders and defendants alike should monitor procedural cost orders as carefully as substantive outcomes in Brazilian IP litigation.
Ltda v Elias — key questions answered
The court granted the appeal and ruled that the full cost of expert witness fees falls on Mavind, the aggrieved party, because only Mavind maintained interest in producing expert evidence. The ruling corrects the lower court’s apportionment of those costs. The underlying infringement merits of BRPI1003853B1 do not appear to have been resolved in this specific ruling.
BRPI1003853B1 is a Brazilian granted patent held by Mavind Indústria de Máquinas e Equipamentos Ltda. It covers guard assembly systems for conveyor equipment — mechanical safety guarding structures used in industrial conveyor lines. The ‘B1’ designation indicates the patent was examined and granted by the Brazilian patent office (INPI).
Under Brazilian civil procedure, costs associated with a procedural step are typically borne by the party that necessitates or benefits from that step. The appellate court found that only Mavind sustained its interest in producing expert evidence. Consequently, the full expert fee was reallocated to Mavind rather than being shared with the defendant.
Based on the publicly available record, the ruling addresses cost apportionment only and does not appear to constitute a merits decision on the infringement claim under BRPI1003853B1. Whether the underlying infringement action was separately resolved or remains pending is not determinable from the available case data.
Enforcing patents against individual defendants in Brazil — rather than corporate entities — can present practical challenges including limited damages recovery and execution risk. This case also illustrates that expert-driven litigation strategies carry full cost exposure for the patent holder if the defendant disengages from the evidentiary process. Rights holders should weigh enforcement target selection and litigation strategy accordingly.
