Correa Filho v. Bortolo: Appeal Overturns Judgment in Pre-Molded Wall Panel Patent Case
João Batista Correa Filho brought an infringement action against Livio Bortolo over utility model patent BR 202017002979-0, covering pre-molded wall panels. The Court of Justice of São Paulo granted the appeal, annulling the lower judgment and ordering the case returned for technical expert examination to properly investigate the alleged counterfeiting.
São Paulo appellate court sends wall panel patent dispute back for expert scrutiny
João Batista Correa Filho initiated an infringement action against Livio Gabriel Bozi Menezes de Bortolo before the Brazilian courts, asserting utility model patent BR 202017002979-0, which covers pre-molded wall panels. The case was filed in 2024 and progressed through the court system in the state of São Paulo. The dispute centres on alleged counterfeiting of a utility model — a form of intellectual property protection in Brazil for incremental, practical innovations in construction technology.
The Court of Justice of São Paulo granted the plaintiff’s appeal, annulling the original trial court judgment. Crucially, the appellate court did not rule on the merits of infringement itself; instead, it determined that the case must be returned to the court of origin for the production of technical expert evidence specifically directed at investigating the alleged counterfeiting of the utility model patent. This outcome suggests the lower court’s judgment was procedurally deficient — likely for failing to commission or adequately consider technical expert analysis before deciding the case.
The appellate ruling is notable because it resets the evidentiary foundation of the case rather than resolving it. The public record does not disclose why the lower court declined to order expert evidence, nor whether an expert was appointed and findings were disputed. What is clear is that the Court of Justice of São Paulo has signalled that utility model counterfeiting claims of this technical complexity require specialist examination before any merits judgment can stand — a significant procedural marker for construction-sector IP disputes in Brazil.

Appeal granted: judgment annulled and remanded for expert evidence
What ‘appeal granted with remand’ means in Brazilian IP proceedings
When a Brazilian appellate court grants an appeal and annuls a judgment, the lower court’s decision is voided and carries no legal weight. The case is not dismissed — it is returned to the trial court to be decided again, this time with the required procedural steps completed. Here, the Court of Justice of São Paulo found the investigation insufficient, specifically requiring technical expert evidence before any finding on patent counterfeiting can be made.
Judgment annulled — case remandedPlaintiff wins the procedural battle, not the war
For Correa Filho, the appeal grant is a meaningful procedural victory. The appellate court agreed that the infringement claim deserved proper technical scrutiny — a validation that the claim was not frivolous. However, no finding of infringement has been made. The case now returns to the origin court, where a technical expert must examine the pre-molded wall panel technology and assess whether the patent was counterfeited. The ultimate merits outcome remains open.
Procedural win — merits unresolvedBortolo faces renewed expert-led investigation on counterfeiting
The defendant’s position is materially weakened by this ruling. Any benefit obtained from the lower court’s judgment — presumably a decision that did not find infringement or dismissed the claim — has been stripped away. Bortolo now faces a remanded proceeding in which a technical expert will specifically examine the alleged counterfeiting of the utility model. The outcome of that expert report is likely to be determinative at the next trial stage.
Lower court benefit lost — re-examination orderedExpert evidence is non-negotiable in Brazilian utility model disputes
This ruling reinforces that Brazilian courts will not permit utility model infringement claims involving technical products — such as pre-molded wall panels — to be resolved without specialist expert analysis. For construction sector companies and individual inventors operating in Brazil, the case signals that patent enforcement actions must be supported by, and adjudicated with, court-appointed technical expertise. Skipping this step risks appellate annulment regardless of underlying merits.

Official order — verbatim text
The appellate court’s ruling is explicitly procedural: the judgment below is annulled not because the patent was found valid or invalid, or because infringement was established or denied, but because the investigation was incomplete. The court’s direction to reopen the case specifically for technical expert evidence on ‘alleged counterfeiting’ of BR 202017002979-0 indicates the appellate panel found the evidentiary record materially deficient. This framing preserves all merits questions for the remand proceeding and prevents either party from claiming the appeal established any substantive right.
BRPI1702979A2 — Pre-Molded Wall Panels Utility Model
BRPI1702979A2 is a Brazilian utility model application covering pre-molded wall panel technology. Utility models in Brazil, governed by the Industrial Property Law (Law No. 9,279/1996), protect functional innovations with a lower inventive step threshold than invention patents, and carry a maximum term of 15 years. The application number BR 202017002979-0 indicates a filing in 2017, placing it within the broader wave of prefabricated construction system innovations. The patent protects the structural or functional configuration of pre-molded panels used in wall construction — a category with growing commercial significance in Brazil’s affordable housing and modular construction markets.
Pre-molded wall panel patents occupy a commercially contested space in Brazil’s construction sector, where prefabricated building technologies have seen significant adoption. A utility model covering panel design or assembly configuration can create meaningful barriers for competing manufacturers if enforced successfully. The fact that this patent has been actively litigated — and that the Court of Justice of São Paulo has ordered expert-level examination of alleged counterfeiting — suggests the commercial stakes are sufficient to sustain multi-year proceedings. Competitors and licensees operating in this product category should treat this patent as an active enforcement risk until the remand proceedings conclude.
Should you run an FTO against BRPI1702979A2?
Any company or individual manufacturing, importing, or commercialising pre-molded wall panels in Brazil should assess their exposure to BRPI1702979A2. The fact that this utility model is being actively enforced in court — and that a Brazilian appellate court has ordered technical expert examination of alleged counterfeiting — signals that the rights holder treats the patent as commercially viable and enforceable. R&D teams developing modular or prefabricated construction systems for the Brazilian market should confirm their designs do not fall within the utility model’s claims before launch or scale.
PatSnap Eureka’s FTO Search Agent enables IP and R&D teams to rapidly map claim scope against product specifications for Brazilian utility models including BRPI1702979A2. Eureka can identify the specific constructional or functional features protected, surface overlapping applications in the prefabricated panel space, and flag related utility models or invention patents held by the same applicant. This is particularly valuable given that Brazilian utility model claims are often broadly drafted and the enforcement landscape — as this case illustrates — can move quickly to technical expert proceedings.

What this case signals for construction IP enforcement in Brazil
This appeal outcome underscores the procedural rigour Brazilian courts apply to utility model infringement claims in the construction sector.
Brazilian courts will annul infringement judgments lacking technical expert evidence
The Court of Justice of São Paulo’s decision to annul and remand is a clear signal: for utility model patents covering technical products like pre-molded wall panels, any judgment rendered without proper technical expert examination is procedurally vulnerable. Parties asserting or defending against such claims should ensure expert evidence is commissioned and on the record before trial concludes.
Utility model patents remain an active enforcement tool for individual inventors in Brazil
This case demonstrates that individual inventors — not just corporations — actively litigate utility model rights in Brazil before state-level appellate courts. The appeal grant shows the Court of Justice of São Paulo is willing to provide meaningful appellate oversight to protect the integrity of utility model enforcement proceedings, even at the individual rights-holder level.
FILHO v LIVIO — key questions answered
The Court of Justice of São Paulo granted the appeal, annulling the lower court judgment and ordering the case returned to the trial court. The appellate court determined that the investigation was insufficient without technical expert evidence specifically addressing the alleged counterfeiting of utility model patent BR 202017002979-0 covering pre-molded wall panels.
BR 202017002979-0 (published as BRPI1702979A2) is a Brazilian utility model application filed in 2017. It covers pre-molded wall panel technology used in construction. Brazilian utility models protect functional or structural innovations with a lower inventive step threshold than standard invention patents and are capped at a 15-year term from filing.
The appellate court’s grant of the appeal voids the lower court’s judgment entirely. No merits finding on infringement stands. The case is returned to the court of origin, where the proceedings must be reopened to allow production of technical expert evidence on the alleged counterfeiting. Both parties retain their substantive positions; the infringement question is unresolved.
Brazilian courts routinely require court-appointed technical experts (peritos) in patent infringement cases involving technical subject matter. The appellate court’s ruling suggests the lower court resolved the dispute without commissioning or adequately considering such evidence — a procedural deficiency that renders the judgment unsustainable under Brazilian civil procedure for IP disputes of this technical complexity.
Manufacturers of pre-molded wall panels or similar prefabricated construction products operating in Brazil face active enforcement risk from this utility model. The ongoing litigation and the appellate court’s support for a full technical investigation signal that the rights holder is committed to enforcement. Companies should conduct an FTO analysis against the utility model’s claims before manufacturing, importing, or distributing competing products in the Brazilian market.
