João Batista Correa Filho v. J R Accacio Engenharia: Appeal Granted
Brazilian individual inventor João Batista Correa Filho successfully appealed against engineering firm J R Accacio Engenharia over alleged infringement of pre-molded wall panel patent BRPI1702979A2. The Court of Justice of São Paulo granted the appeal on 19 June 2024, also awarding gratuitous justice benefits to the applicant.
Individual inventor wins appeal in São Paulo wall panel patent dispute
This infringement action, filed before the Court of Justice of São Paulo under case number 2131452-65.2024.8.26.0000, pits individual inventor João Batista Correa Filho against engineering company J R Accacio Engenharia. The dispute centres on Brazilian patent application BRPI1702979A2, which covers pre-molded wall panel technology — a segment of the construction sector with growing commercial relevance in Brazil’s modular and prefabricated building market.
The Court of Justice of São Paulo granted the appeal on 19 June 2024. Critically, the court’s ruling includes a grant of gratuitous justice (gratuidade de justiça) in favour of the applicant, meaning the inventor is relieved of court costs and fees for the proceedings. This ruling suggests the lower-instance decision had denied that benefit, and the appellate court found the applicant’s financial circumstances warranted it. The appeal being granted does not necessarily resolve the infringement merits with finality — it may remit the case for further proceedings.
The relatively swift closure date of 19 June 2024 and the procedural nature of the grant — focused on access-to-justice relief — suggest this appeal stage addressed preliminary or interlocutory matters rather than a full merits determination. What remains unclear from the public record is whether the underlying infringement claim will proceed to full trial on the merits, and what specific technical acts by J R Accacio Engenharia are alleged to infringe BRPI1702979A2.

São Paulo appeal granted: what the ruling means for both parties
Appeal granted — procedural relief, not final merits ruling
Under Brazilian civil procedure, granting an appeal at this stage typically means the appellate chamber found reversible error or an unaddressed issue in the lower court’s decision. Here, the specific relief granted is gratuitous justice — access to proceedings without paying court fees. This is a procedural victory that clears the path for the inventor to pursue his infringement claim without the financial barrier of court costs.
Procedural victoryInventor gains fee-free access to pursue infringement claim
For João Batista Correa Filho, the ruling is a meaningful win: the Court of Justice of São Paulo has recognised his financial eligibility for gratuidade de justiça, removing cost barriers that could otherwise prevent an individual inventor from litigating against an engineering firm. His infringement action over pre-molded wall panel technology can now proceed without the risk of adverse cost liability halting the case prematurely.
Access to justice securedEngineering firm faces continued infringement exposure
For J R Accacio Engenharia, the appeal outcome means the inventor’s case is now better resourced to proceed. The gratuitous justice grant does not adjudicate infringement, but it signals the litigation will continue. The defendant should anticipate further proceedings on the merits of whether its activities relating to pre-molded wall panels infringe BRPI1702979A2. Early FTO analysis of the patent’s claims would be advisable.
Merits proceedings likely aheadPrefabricated construction sector faces inventor IP enforcement risk
This case is consistent with a broader trend of individual inventors actively enforcing construction-technology patents in Brazilian courts. For companies operating in the pre-molded or prefabricated wall panel segment, the case suggests that BRPI1702979A2 remains an active litigation risk. Competitors and suppliers using similar modular wall panel systems should consider freedom-to-operate assessments against this patent application before scaling production.

Official order — verbatim text
The court’s phrasing — ‘examination of the specific situation leads to the grant of the benefits of gratuitous justice’ — indicates the ruling is squarely procedural, not a determination on infringement merits. The appellate chamber applied a means-based assessment to award fee exemption. For the patent holder, this removes a practical litigation barrier. For J R Accacio Engenharia, the absence of a merits finding means infringement liability remains unresolved and the substantive dispute over pre-molded wall panel technology is likely to continue at first instance.
BRPI1702979A2 — Pre-Molded Wall Panel Construction Technology
BRPI1702979A2 is a Brazilian patent application covering pre-molded wall panel technology — a construction method in which wall components are fabricated off-site or in controlled conditions and assembled on location. The ‘BR PI’ designation indicates a Brazilian national phase patent application. Pre-molded systems are increasingly relevant to Brazil’s social housing and commercial construction sectors, where speed, cost efficiency, and labour reduction drive demand for prefabricated components.
Strategically, BRPI1702979A2 sits in a competitive segment: Brazilian construction firms, engineering companies, and building-materials manufacturers are all active participants in the pre-molded wall panel market. An individual inventor holding enforceable rights in this space can present a meaningful barrier to engineering firms scaling prefab construction operations. The patent’s continued prosecution and litigation activity suggests the inventor views it as commercially significant and worth defending through the courts.
Should you run an FTO against BRPI1702979A2?
Any engineering firm, construction contractor, or building-materials company active in Brazil’s prefabricated or pre-molded wall panel sector should treat BRPI1702979A2 as a priority FTO target. The active infringement litigation against J R Accacio Engenharia demonstrates the patent holder is willing to enforce — and now has court-supported access to do so. Product teams designing or sourcing pre-molded wall systems for the Brazilian market should map their technical specifications against the patent’s claim language before commercial rollout.

What this case signals for Brazil’s construction IP landscape
Individual inventors are leveraging Brazilian courts to enforce construction patents against established engineering firms — with appellate courts supporting access to justice.
Gratuidade grants level the playing field for individual inventors
The São Paulo court’s willingness to award gratuitous justice to an individual inventor pursuing an engineering firm signals that financial asymmetry alone will not block enforcement. Companies in Brazil’s prefabricated construction sector should not assume individual patentees lack the means to sustain litigation — procedural mechanisms actively reduce that barrier.
BRPI1702979A2 remains an active enforcement risk for wall panel manufacturers
With the infringement action now proceeding with court-supported access, the pre-molded wall panel patent BRPI1702979A2 represents a live IP risk. Engineering and construction firms using comparable modular wall panel systems in Brazil should audit their product designs against the patent’s claims before further commercial expansion.
Filho v J — key questions answered
The court granted the appeal filed by João Batista Correa Filho, awarding him gratuitous justice — relief from court fees and costs. The ruling is procedural rather than a merits determination on the infringement of pre-molded wall panel patent BRPI1702979A2. The underlying infringement action against J R Accacio Engenharia is expected to continue.
BRPI1702979A2 is a Brazilian patent application filed by João Batista Correa Filho covering pre-molded wall panel technology.

Gratuidade de justiça is a Brazilian legal benefit that exempts a party from court fees, legal costs, and related expenses during litigation. It is granted based on an assessment of the applicant’s financial circumstances. In patent cases, it can allow individual inventors to pursue enforcement actions against better-resourced corporate defendants without facing prohibitive cost exposure.
No. The appeal granted by the Court of Justice of São Paulo specifically concerns the procedural grant of gratuitous justice — not the substantive question of whether J R Accacio Engenharia infringed BRPI1702979A2. The infringement merits remain unresolved based on the available public record, and further proceedings are likely.
BRPI1702979A2 represents an active enforcement risk for Brazilian engineering and construction companies using pre-molded wall panel systems. The patent holder has demonstrated willingness to litigate and now has court-supported access to proceedings. Firms should conduct freedom-to-operate analysis against the patent’s claims and consider whether their wall panel designs fall within its scope before scaling operations in Brazil.
