Altipisos v. Oliveira: São Paulo Appeal Dismissed in Floor Plate Patent Dispute
Altipisos Revestimentos e Quadras Esportivas Ltda brought a patent action against Emerson Cordeiro de Oliveira concerning Brazilian utility model BRMU1928317U2, which covers a floor plate with dampening impact technology. The Court of Justice of São Paulo declined to hear the appeal on procedural grounds, issuing a ‘not known’ determination that terminated the case without a merits ruling.
São Paulo Court Declines Appeal in Sports Flooring Patent Row
Altipisos Revestimentos e Quadras Esportivas Ltda, a Brazilian company operating in the flooring and sports court resurfacing sector, initiated proceedings against individual defendant Emerson Cordeiro de Oliveira in connection with Brazilian utility model patent BRMU1928317U2. The patent covers a floor plate incorporating impact-dampening technology, a product category commercially relevant to sports courts, gymnasiums, and high-traffic flooring applications.
The case reached the Court of Justice of São Paulo at the appellate tier, where the court issued a determination that the appeal was ‘NOT KNOWN’ — a procedural outcome under Brazilian civil procedure indicating the appeal failed to satisfy admissibility requirements. The court did not reach the substantive merits of the patent dispute, meaning neither the validity of BRMU1928317U2 nor any infringement allegation was adjudicated at this level.
Because the filing date is absent from the available public record, the full duration of proceedings cannot be assessed. The ‘not known’ outcome suggests the appeal likely failed on procedural grounds such as missing deadlines, inadequate grounds of appeal, or lack of standing — though the public record is silent on the precise basis. The underlying first-instance proceedings and their outcome remain undisclosed in the available data.

Appeal not known: what the São Paulo ruling means for both parties
A ‘not known’ appeal: procedural bar, not a merits loss
Under Brazilian civil procedure, an appeal declared ‘não conhecido’ (not known) is rejected at the admissibility stage — the appellate court declines to examine the substantive arguments. Common grounds include failure to meet filing deadlines, insufficient reasoning, lack of standing, or non-payment of court fees. This outcome means the appellate court expressed no view on the patent’s validity or any alleged infringement.
Procedural dismissalAppellant’s appeal extinguished without merits review
Whichever party lodged the appeal — the public record does not specify — faces a closed avenue at this appellate tier. A ‘not known’ determination typically forecloses further pursuit of the same appeal. The appellant may need to assess whether extraordinary appellate remedies (such as a recurso especial or recurso extraordinário in the Brazilian system) are available, though procedural bars may apply.
Appeal avenue closedRespondent benefits from appeal’s collapse, but risk may persist
The party who succeeded at first instance — if any — likely retains that outcome given the appeal was not heard on the merits. However, because the underlying first-instance result is not disclosed in the available public record, the precise benefit to the respondent is uncertain. If the first-instance decision was adverse to Altipisos, the patent holder may yet pursue other procedural routes.
First-instance result unclearBRMU1928317U2 remains in limbo without a definitive ruling
The impact-dampening floor plate patent covered by BRMU1928317U2 has not been judicially validated or invalidated through this proceeding. Competitors and licensees in the Brazilian sports flooring and resurfacing market should note that the enforceability of this utility model has not been authoritatively tested at the merits level. An FTO assessment against this patent remains prudent for any party active in this product space.

Official order — verbatim text
The court’s declaration that the appeal is ‘NOT KNOWN’ reflects a threshold admissibility ruling under Brazilian appellate procedure — the tribunal declined to examine the substance of the dispute. This phrasing is distinct from a merits dismissal: it signals a procedural defect in the appeal itself, not a finding on the patent’s validity or the alleged infringement of BRMU1928317U2. The practical effect is that the appellate record closes without resolving the underlying commercial dispute, leaving the enforceability of the impact-dampening floor plate utility model unaddressed at this level.
BRMU1928317U2 — Impact-Dampening Floor Plate Technology
BRMU1928317U2 is a Brazilian utility model patent protecting a floor plate incorporating impact-dampening technology. Utility models in Brazil, administered by the INPI, protect functional innovations in the form, configuration, or structure of an object and carry a 15-year term from the filing date. The dampening floor plate technology is directly applicable to sports courts, gymnasiums, indoor arenas, and high-traffic commercial flooring — markets where impact absorption is both a performance and safety requirement.
The commercial significance of this patent lies in the growing Brazilian market for engineered sports surfaces and resilient flooring systems. A utility model covering the structural configuration of an impact-dampening plate could restrict competitors from manufacturing or importing substantially similar flooring systems without a licence. Given that this case reached the appellate tier without a merits ruling, the patent’s enforceability has not been judicially stress-tested — elevating the risk for any party developing or distributing analogous floor plate systems in Brazil.
Should your team run an FTO against BRMU1928317U2?
Any company developing, manufacturing, or importing impact-dampening floor plates, sports court tiles, or resilient flooring panels for the Brazilian market should assess freedom to operate against BRMU1928317U2. The absence of a merits ruling means the patent’s claim scope has not been judicially construed, which creates uncertainty about what designs fall within or outside its protection. R&D teams designing flooring systems with cushioning or shock-absorption layers should treat this utility model as an active consideration.

What this case signals for the Brazilian sports flooring IP landscape
A procedurally dismissed appeal leaves patent enforceability unresolved — a strategic ambiguity that competitors and licensees must actively manage.
Procedural dismissals leave patent risk unresolved for competitors
When an appeal is dismissed on admissibility grounds, the underlying patent is neither validated nor invalidated. Companies operating in Brazil’s sports court and impact-flooring sector should treat BRMU1928317U2 as an active risk asset until a merits ruling is obtained, either through fresh proceedings or an INPI administrative challenge.
Brazilian utility models carry a shorter validity window — but enforcement risk is real
Brazilian utility model patents (modelo de utilidade) carry a 15-year term from filing. Without a merits-level challenge, the holder retains enforcement rights for the remaining term. Product teams developing impact-dampening flooring solutions for sports or commercial applications should factor this into market-entry and FTO planning.
LTDA v EMERSON — key questions answered
The Court of Justice of São Paulo declared the appeal ‘not known’ (não conhecido), meaning it was rejected at the admissibility stage without any examination of the merits. The court did not rule on the validity of BRMU1928317U2 or any infringement claim. This procedural outcome typically results from a defect in the appeal itself — such as missed deadlines or insufficient grounds — rather than the substance of the dispute.
BRMU1928317U2 is a Brazilian utility model (modelo de utilidade) protecting a floor plate with impact-dampening technology, applicable to sports courts and commercial flooring. Brazilian utility models are granted by the INPI and carry a 15-year term from the filing date. They protect functional innovations in the form or structure of an object, offering a lower inventive step threshold than a standard invention patent.
The plaintiff is Altipisos Revestimentos e Quadras Esportivas Ltda, a Brazilian company in the flooring and sports court sector and apparent holder of BRMU1928317U2. The defendant is Emerson Cordeiro de Oliveira, an individual. The case was heard at the Court of Justice of São Paulo, which is São Paulo state’s appellate-level civil court.
The dismissal does not invalidate the patent — BRMU1928317U2 remains in force for its statutory term unless challenged through INPI administrative proceedings or a separate judicial nullity action. However, because no merits ruling was issued, the claim scope and validity of the utility model have not been authoritatively construed by a Brazilian court, leaving some commercial uncertainty for third parties in the impact-flooring space.
The party that lodged the appeal may explore extraordinary appellate remedies available under Brazilian civil procedure, such as a recurso especial to the Superior Tribunal de Justiça if federal law was violated, though procedural bars may apply following a ‘not known’ determination. Separately, either party could initiate or respond to an INPI administrative challenge to the utility model’s validity. The public record does not disclose the first-instance outcome, which would be central to assessing the next strategic steps.
