Interglass v Box Elegance: São Paulo Court Dismisses Second Patent Appeal
Interglass Comercio de Ferragens e Acessórios para Vidros Eireli pursued appellate review against Box Elegance Ltda over patent BRMU1871918U2, covering an arrangement for an oblong holder tube. The Court of Justice of São Paulo rejected a motion for clarification and declined to hear the second appeal, closing the matter without a merits ruling.
São Paulo appellate court closes glass fittings patent dispute
Interglass Comercio de Ferragens e Acessórios para Vidros Eireli initiated proceedings against Box Elegance Ltda asserting rights under Brazilian utility model patent BRMU1871918U2, which protects an arrangement for an oblong holder tube — a component associated with glass hardware and fittings. The case was filed before the Court of Justice of the State of São Paulo and the appeal record was assigned case number 2050156-84.2025.8.26.0000/50000.
The appellate court issued a ruling on 24 June 2025 rejecting Interglass’s motion for clarification and simultaneously declining jurisdiction over the second appeal filed under ancillary number 2050156-84.2025.8.26.0000/50001. Because the court expressly stated it was ‘not aware’ of the second appeal, the dismissal is procedural in nature — no substantive finding on patent validity or infringement was made. The basis of termination is recorded as ‘Appeal Dismissed.’
The absence of a filing date in the public record makes it difficult to assess the full duration of proceedings. The outcome suggests the second appeal may have failed to meet admissibility requirements under Brazilian civil procedure rules, which typically require that a motion for clarification (embargos de declaração) raise genuine omission, contradiction, or obscurity in the prior decision. What remains unknown from the public record is whether the underlying first-instance or earlier appellate decision favoured Interglass or Box Elegance.

Appeal dismissed: what the São Paulo ruling means for both parties
Procedural dismissal — no merits ruling on the patent
Under Brazilian appellate procedure, a second appeal (recurso de segundo grau) must satisfy strict admissibility thresholds. The court’s language — ‘I AM NOT AWARE’ — is consistent with a formal declaration of non-cognisance (não conhecimento do recurso), meaning the court refused to examine the appeal on procedural grounds rather than deciding whether the patent was valid or infringed. The rejection of the clarification motion reinforces that the prior ruling contained no correctable defect.
Non-cognisance — procedural barInterglass loses appellate avenue without merits vindication
For Interglass, the dismissal closes this particular appellate pathway without any judicial confirmation that BRMU1871918U2 is valid or infringed. The patent holder may still hold enforceable IP rights, but this ruling provides no precedential support for those rights. Further enforcement actions would need to restart at an appropriate procedural level, potentially before a different court or through INPI-administered channels.
No precedential benefit gainedBox Elegance avoids merits ruling but gains no infringement clearance
Box Elegance benefits in the short term from the dismissal — no adverse finding of infringement was made. However, because the court did not adjudicate validity or infringement, Box Elegance cannot rely on this outcome as a finding that it does not infringe BRMU1871918U2. The patent remains in force, and Interglass could theoretically pursue separate proceedings. Box Elegance should ensure ongoing freedom-to-operate analysis for its oblong tube holder products.
No infringement clearance grantedGlass fittings sector: patent dispute unresolved in substance
For competitors in the Brazilian glass hardware and accessories market, this outcome leaves the commercial scope of BRMU1871918U2 legally untested. Utility model patents in Brazil are granted without substantive examination, which makes judicial validation particularly significant — and its absence here means uncertainty persists. Companies manufacturing or distributing oblong tube holder arrangements in Brazil should consider independent FTO assessments rather than relying on the outcome of this appeal.

Official order — verbatim text
The court’s ruling combines two distinct procedural acts: outright rejection of the embargos de declaração (clarification motion) and a declaration of non-cognisance of the second appeal. Under Brazilian civil procedure, ‘não conhecer’ of an appeal means the court determined it lacked grounds to examine the substance — typically due to inadmissibility, missing preconditions, or exhaustion of permissible appeal tiers. No finding was made on patent validity or infringement of BRMU1871918U2, leaving the substantive legal position of both Interglass and Box Elegance unchanged.
BRMU1871918U2 — Arrangement for an Oblong Holder Tube
BRMU1871918U2 is a Brazilian utility model (modelo de utilidade) registration, as indicated by the ‘MU’ designation in the INPI numbering system. Utility models in Brazil protect functional improvements to existing objects and enjoy a 15-year term from filing. The patent covers an ‘arrangement for a holder tube oblong’ — a structural or functional configuration of an oblong-profile tube used in glass panel support, door hardware, or shower enclosure fittings, consistent with Interglass’s stated commercial activity in glass accessories.
Brazilian utility models are granted without full substantive examination, meaning BRMU1871918U2 has not necessarily been scrutinised for novelty or inventive step by INPI. This makes judicial or administrative challenge by competitors both legally available and commercially rational. For the glass hardware sector, where product differentiation in holder and frame components is narrow, a utility model of this type — if valid and broadly claimed — could meaningfully restrict competing product lines sold in the Brazilian market.
Should you run an FTO against BRMU1871918U2?
Any business manufacturing, importing, or distributing oblong tube holder arrangements, glass door fittings, or shower enclosure hardware for the Brazilian market should assess exposure to BRMU1871918U2. The patent remains in force and was not invalidated in these proceedings. Given that Brazilian utility models are granted without full examination, the actual claim scope may be narrower than initially filed — but that can only be confirmed through proper claim mapping against your product geometry.

What this case signals for the Brazilian glass fittings IP landscape
Procedural dismissals in São Paulo appellate proceedings leave commercial risk unresolved — and utility model holders may pursue alternative enforcement routes.
Brazilian utility models carry infringement risk even after failed appeals
BRMU1871918U2 was never found invalid or uninfringed in this case. A procedural dismissal at the appellate level does not extinguish the patent or create an estoppel against future enforcement. Businesses in the glass hardware fittings sector operating in Brazil should treat this outcome as inconclusive — not as IP clearance.
Non-cognisance rulings signal procedural strategy failures — not weak patents
The court’s refusal to hear the second appeal suggests Interglass may have exhausted admissible appellate routes or filed procedurally deficient motions. This is a common risk in multi-stage Brazilian litigation. IP teams should map Brazilian appellate admissibility requirements carefully before filing embargos de declaração or second-level appeals.
Eireli v Box — key questions answered
It means the Court of Justice of São Paulo refused to examine the second appeal on the merits, finding it inadmissible. No finding was made on whether BRMU1871918U2 was infringed or valid. The patent and any underlying first-instance ruling remain unaffected by this specific procedural outcome.
No. The appeal was dismissed on procedural grounds and the court did not adjudicate validity or infringement. BRMU1871918U2 remains registered with INPI. Its validity could still be challenged through an administrative nullity petition or in separate civil proceedings.
Brazilian utility models (modelos de utilidade) protect functional improvements to objects and are granted by INPI without full substantive examination for novelty or inventive step. They carry a 15-year term. BRMU1871918U2 is registered under this regime, meaning its claims have not been formally tested for validity by INPI — making administrative challenge a viable commercial strategy.
Potentially, yes. The dismissal was procedural, not a finding on the merits. Interglass could initiate separate first-instance infringement proceedings, though res judicata considerations would depend on what was decided in the underlying case. The public record of this appeal does not disclose the outcome of the prior instance.
Embargos de declaração is a Brazilian procedural motion requesting that a court clarify, correct, or complete a prior ruling due to omission, contradiction, or obscurity. The court’s rejection here suggests the prior ruling did not contain any of these defects as a matter of law, and that the motion was used — as is common in Brazilian practice — as a delaying or procedural stepping-stone rather than to correct a genuine defect.
