Altipisos v. Oliveira: São Paulo Court Grants Appeal, Orders Expert Analysis
Altipisos R. and Quadras Esportivas Ltda asserted two Brazilian utility model patents — BRMU1928317U2 and BRMU1424725U2 — covering impact-dampening and tactile rubber flooring against Emerson Cordeiro de Oliveira. The Court of Justice of São Paulo granted the appeal, revoking a lower-court urgent relief order and mandating technical expertise before any infringement finding can be made.
São Paulo appellate court halts interim relief in rubber floor patent row
Altipisos R. and Quadras Esportivas Ltda, a Brazilian company active in the sports flooring and court surfaces sector, brought an infringement action before the Court of Justice of São Paulo against individual defendant Emerson Cordeiro de Oliveira. The dispute centres on two Brazilian utility model patents: BRMU1928317U2, relating to a floor plate with dampening impact, and BRMU1424725U2, covering tactile rubber floor and floor systems. The plaintiff alleged that the defendant’s activities infringed its registered industrial property rights in these specialist rubber flooring technologies.
The lower court had granted urgent (interim) relief in favour of Altipisos, consistent with a preliminary finding that infringement was sufficiently plausible to warrant immediate protection. On appeal, however, the Court of Justice of São Paulo reversed that interim measure. The appellate panel determined that the question of infringement — given the technical complexity of the patents at issue — could not be resolved without a formal technical expertise assessment. The appeal was therefore granted, urgent relief was revoked, and the case was ordered to continue through regular procedural instruction, including expert examination.
The resolution at this stage reflects a procedural pivot rather than a final merits determination: no finding of infringement or non-infringement has been made. The appellate court’s insistence on technical expertise before granting injunctive protection suggests the infringement question is genuinely contested and technically complex. The absence of filing date data in the public record limits duration analysis, and the outcome of the forthcoming expert phase — which will be determinative — remains unknown at this stage.

Appeal granted: what the São Paulo ruling means for both parties
Appellate court revokes interim injunction — why this matters
In Brazilian civil procedure, urgent (tutela de urgência) relief may be granted provisionally where the applicant demonstrates probability of the right and risk of harm. By granting the appeal and revoking that relief, the São Paulo court signalled that the threshold for interim protection had not been sufficiently demonstrated — specifically because infringement cannot be confirmed without technical expertise. This is a procedural reversal, not a merits finding.
Interim relief revokedAltipisos loses interim protection — case remains live
Altipisos loses the immediate injunctive shield it had secured at first instance. The defendant may continue the allegedly infringing activities during the expert phase unless further interim measures are sought and granted. Critically, Altipisos’s underlying infringement claim has not been dismissed — the patents remain in force and the merits will be tested once the technical expert report is produced. The outcome of that expertise phase will be decisive.
Injunction revoked; claim survivesOliveira free to operate pending technical review
The appeal outcome is a significant procedural win for the defendant: the injunctive restraint is lifted, and commercial activities are no longer immediately restricted. However, the infringement action continues. If the forthcoming technical expertise confirms infringement of BRMU1928317U2 or BRMU1424725U2, the defendant faces renewed enforcement risk — including potential damages covering the period during which activities continued post-revocation. This is a stay, not an acquittal.
Interim restraint liftedTechnical expertise phase now pivotal for rubber flooring IP
The court’s insistence on expert evidence before granting injunctive relief sets a meaningful standard for utility model enforcement in Brazilian flooring technology disputes. Companies asserting industrial property rights in this sector — particularly where utility models cover incremental design variants — should anticipate that Brazilian appellate courts may require independent technical validation before interim measures are upheld. This increases the cost and timeline of preliminary enforcement strategies.

Official order — verbatim text
The appellate panel’s language — ordering ‘regular instruction of the case’ and technical expertise before any infringement determination — reflects a deliberate refusal to decide the merits at the interim stage. The phrasing ‘with certainty, the existence or not of infringement’ is significant: it sets a high factual standard and signals that the court views the underlying technical question as genuinely open. Neither party can read this ruling as a substantive win on infringement; it is purely a procedural recalibration of the evidentiary process.
BRMU1928317U2 & BRMU1424725U2 — Rubber and Tactile Flooring Systems
BRMU1928317U2 is a Brazilian utility model covering a floor plate specifically engineered to dampen impact — technology directly relevant to sports courts, gymnasiums, and high-traffic commercial floors where surface resilience is a performance requirement. BRMU1424725U2 extends Altipisos’s registered rights into tactile rubber floor systems, which serve both functional and accessibility purposes. Utility models in Brazil (modelos de utilidade) protect functional innovations with a lower inventive step threshold than invention patents, making them a common tool for incremental product differentiation in materials and construction sectors.
For the Brazilian sports flooring and quadras esportivas market, these two utility models together create overlapping IP coverage across the core product lines Altipisos commercialises. Competitors developing or distributing rubber floor systems in Brazil — particularly those targeting sports courts, public spaces, or accessibility-compliant installations — face meaningful freedom-to-operate questions. The ongoing litigation, and the imminent technical expertise phase, will clarify the precise scope of protected features, making this a closely watched reference point for the sector.
Should you run an FTO against BRMU1928317U2 and BRMU1424725U2?
Any company manufacturing, importing, or distributing rubber floor systems — impact-dampening tiles, sports court surfaces, or tactile paving — in Brazil should assess its exposure against both Altipisos utility models. The pending technical expertise in this case will define the claim boundaries that Brazilian courts consider determinative. Acting before that expert report is published allows product teams to identify design-around options while they still have flexibility.

What this case signals for rubber flooring IP enforcement in Brazil
A São Paulo appellate reversal of interim relief highlights the evidentiary bar for utility model enforcement in Brazil’s industrial flooring sector.
Brazilian courts demand technical proof before interim injunctions hold
This case illustrates that the Court of Justice of São Paulo will scrutinise whether infringement is technically substantiated before allowing urgent relief to stand. Patent holders asserting utility models in technically complex product categories — such as engineered rubber flooring — should prepare detailed expert-ready claim mapping from the outset, not as a later-stage fallback.
Utility model portfolios need expert-backed enforcement strategies
BRMU1928317U2 and BRMU1424725U2 cover specialist rubber floor systems where the line between competing products may be technically fine. Enforcement strategies for utility models in this space should anticipate that Brazilian appellate panels will require independent expertise, extending the timeline to injunctive relief and increasing upfront costs for the patent holder.
LTDA v EMERSON — key questions answered
The court granted the appeal filed by the defendant, revoking the urgent relief (interim injunction) that the lower court had granted in favour of Altipisos. The case was ordered to continue with regular procedural instruction, including a mandatory technical expertise to determine whether infringement of BRMU1928317U2 or BRMU1424725U2 occurred. No final merits ruling on infringement was made.
BRMU1928317U2 is a Brazilian utility model covering a floor plate with impact-dampening properties. BRMU1424725U2 covers tactile rubber floor and floor systems. Both are registered industrial property rights held by Altipisos R. and Quadras Esportivas Ltda and form the basis of the infringement action against Emerson Cordeiro de Oliveira.
The appellate court determined that the technical complexity of the infringement question — involving the specific features of rubber and tactile floor systems — meant that a conclusive determination could not be made without independent technical expertise. The absence of that expert evidence was sufficient grounds to revoke the urgent relief and require further procedural instruction before any injunction could validly stand.
The case continues at the trial level with regular instruction, meaning both parties will present evidence and a court-appointed technical expert will examine the products and patents at issue. The expert’s report will assess whether the defendant’s floor products infringe the claims of BRMU1928317U2 and BRMU1424725U2. The final infringement determination depends on that expertise phase.
A granted appeal revoking urgent relief means the defendant is no longer under an active injunction during the pending proceedings. The defendant may continue their activities — subject to any new interim measures — while the technical expertise is conducted. However, if infringement is ultimately confirmed at trial, the defendant may face damages liability covering the period of continued activity. The appeal outcome is procedural, not a final acquittal on the merits.
