João Batista Correa Filho v. Una Lar Construtora: Appeal Granted on Pre-Molded Wall Panel Patent
Individual inventor João Batista Correa Filho pursued an infringement action against Una Lar Construtora Inovações at the Court of Justice of São Paulo over pre-molded wall panel technology covered by BRPI1702979A2. The appeal was granted in June 2024, with the court directing collection of appeal preparation fees from the appellant within 15 days.
Inventor enforces wall panel patent at São Paulo appellate court
This infringement action was brought by individual inventor João Batista Correa Filho against Una Lar Construtora Inovações before the Court of Justice of São Paulo, case number 2093206-97.2024.8.26.0000. The asserted intellectual property is Brazilian patent application BRPI1702979A2, which covers pre-molded wall panel technology — a construction sector innovation with applications in prefabricated building systems. The case was closed on 6 June 2024.
The court granted the appeal but determined that the appellant could not benefit from equivalence to legal needy status for purposes of fee exemption. As a result, the court ordered the appellant to collect and pay the appeal preparation fees within 15 days of notification of the judgment, under penalty of registration in active debt. The ruling suggests a procedural resolution focused on fee qualification rather than a full merits adjudication of the infringement claim.
The public record does not disclose a substantive finding on patent infringement or validity in this appellate decision. The outcome is consistent with a procedural determination at the appellate stage regarding the appellant’s financial status and fee obligations. What drove the underlying dispute — and whether a merits-based infringement finding was reached at first instance — remains unclear from the available record.

Appeal granted: what the São Paulo ruling means for both parties
Appeal granted — but on procedural, not merits grounds
The Court of Justice of São Paulo granted the appeal, but the decision centres on fee qualification rather than infringement merits. The court rejected the appellant’s claim to equivalence with legal needy status, which would have exempted them from appeal preparation fees. This is a procedural ruling — the public record does not confirm a substantive infringement finding was made at this stage.
Procedural — fee qualificationInventor faces fee obligation with active debt risk
João Batista Correa Filho, as the individual inventor-litigant, was denied fee-exempt status and must pay appeal preparation fees within 15 days of notification. Failure to comply risks registration in active debt — a significant consequence for an individual claimant. The outcome suggests the court found insufficient grounds to grant the financial exemption sought, which may affect the inventor’s ability to continue enforcement proceedings.
Fee obligation — 15-day deadlineUna Lar benefits from procedural resolution without merits ruling
Una Lar Construtora Inovações avoids a substantive infringement finding at this appellate stage. The decision does not establish liability or damages related to BRPI1702979A2. However, the underlying infringement action may persist depending on whether the plaintiff satisfies the fee requirement and whether the appeal proceeds to a merits determination. The defendant’s exposure to the patent claim is not conclusively resolved.
No merits finding — exposure remainsPrefab construction sector: individual inventor enforcement risk
This case illustrates that individual inventors in Brazil’s construction technology sector are willing to pursue appellate enforcement of pre-molded panel patents. Companies operating in the prefabricated wall and modular construction space should monitor BRPI1702979A2 and similar filings. The procedural resolution here does not extinguish the underlying patent rights, and the technology domain remains an active area for IP enforcement activity.

Official order — verbatim text
The court’s verdict focuses entirely on the appellant’s fee status, determining that equivalence to legal needy classification is not available in these circumstances. The 15-day fee collection order with active debt penalty as a sanction is a standard Brazilian procedural mechanism. Notably, the verdict does not contain language resolving the infringement claim on its merits — the phrase ‘respecting the understanding of the Majority’ suggests a collegiate panel ruling, but the substantive patent dispute appears unresolved at this stage of proceedings.
BRPI1702979A2 — pre-molded wall panel construction technology
BRPI1702979A2 is a Brazilian patent application filed by João Batista Correa Filho covering pre-molded wall panel technology. The BRPI designation indicates a Brazilian national phase patent application. Pre-molded wall panels are a key component in prefabricated and modular construction, enabling faster on-site assembly, reduced labour costs, and improved structural consistency. The technology sits at the intersection of civil engineering innovation and construction industrialisation — a growing priority in Brazilian housing and commercial construction markets.
The strategic significance of BRPI1702979A2 lies in the expanding Brazilian market for industrialised construction. As construction companies adopt prefabricated systems to meet housing demand, patents covering panel design, joining methods, and assembly processes carry material commercial value. The active enforcement of this application by an individual inventor against a commercial construtora signals that even application-stage rights are being wielded as litigation tools — a dynamic that increases IP risk for firms scaling prefab panel operations in Brazil.
Should you run an FTO against BRPI1702979A2?
Any company manufacturing, importing, or installing pre-molded wall panels in Brazil should treat BRPI1702979A2 as a live FTO consideration. The fact that this is a patent application — rather than a granted patent — does not eliminate risk: Brazilian law provides provisional protection for published applications, and litigation has already been initiated. R&D and product teams developing prefabricated construction systems should map their panel geometries, joining systems, and installation methods against the published claims before entering or scaling in the Brazilian market.

What this case signals for the Brazilian construction tech IP landscape
Individual inventors are actively enforcing construction patents at appellate level in Brazil — a dynamic that raises exposure for sector players.
Procedural hurdles do not extinguish underlying patent rights
A fee-related appellate ruling does not resolve the merits of the BRPI1702979A2 infringement claim. Construction companies operating in pre-molded and prefabricated panel segments should not treat this outcome as a clean bill of health — the patent remains in force and the inventor retains enforcement rights if procedural requirements are met.
Individual inventor litigation in Brazil deserves serious monitoring
This case is consistent with a broader pattern in which individual inventors assert construction technology patents against commercial builders. The Court of Justice of São Paulo is an active venue for such disputes. Companies with prefabricated wall panel products in the Brazilian market should run FTO checks against Brazilian construction patent filings, including BRPI-series applications.
FILHO v UNA — key questions answered
The Court of Justice of São Paulo granted the appeal in June 2024 but ruled on procedural grounds — specifically that the appellant could not claim equivalence to legal needy status. The court ordered collection of appeal preparation fees within 15 days under penalty of active debt registration. No substantive infringement finding on BRPI1702979A2 is disclosed in the public record.
BRPI1702979A2 is a Brazilian patent application covering pre-molded wall panel technology. These panels are used in prefabricated and modular construction systems, enabling faster assembly and reduced on-site labour. The application is relevant to any company manufacturing, distributing, or installing prefabricated wall systems in Brazil, as it has been actively asserted in litigation by the individual inventor.
In this case, ‘appeal granted’ refers to the court accepting jurisdiction over and processing the appeal, while simultaneously ruling on a procedural matter — the appellant’s fee exemption request. It does not necessarily mean the underlying infringement claim was decided in favour of either party. The ruling directed the appellant to pay appeal preparation fees, suggesting the court found the exemption claim unmeritorious.
The procedural nature of this ruling means the underlying patent infringement claim against Una Lar Construtora Inovações is not conclusively resolved. BRPI1702979A2 remains an active application. Construction firms with prefabricated wall panel products in Brazil should conduct an FTO analysis and monitor the prosecution and litigation status of this application to assess ongoing exposure.
Active debt (‘dívida ativa’) registration in Brazil is a formal mechanism by which unpaid court-ordered fees are recorded by public authorities and become enforceable as tax-type obligations. In this case, failure by the appellant to pay appeal preparation fees within 15 days would result in registration in active debt — a significant legal and financial consequence that can affect credit status and enable enforcement proceedings against the debtor.
