Interglass v Box Elegance: São Paulo Appeal Dismissed on Oblong Holder Tube Patent
Interglass Comercio de Ferragens and Acessórios para Vidros Eireli pursued a second appeal against Box Elegance Ltda before the Court of Justice of São Paulo over utility model BRMU1871918U2, covering an arrangement for a holder tube oblong used in glass hardware and accessories. The court rejected the motion for clarification and declined jurisdiction over the second appeal, closing the case on 24 June 2025.
São Paulo Court Turns Away Second Appeal in Glass Hardware Utility Model Dispute
Interglass Comercio de Ferragens and Acessórios para Vidros Eireli, a Brazilian glass hardware and accessories supplier, brought proceedings against Box Elegance Ltda in the Court of Justice of São Paulo asserting rights under utility model BRMU1871918U2, which protects an arrangement for a holder tube oblong — a structural component used in the glass fittings sector. The case file reference 2050156-84.2025.8.26.0000/50001 represents the second appeal stage of the litigation, with the original dispute proceeding under case 2050156-84.2025.8.26.0000/50000.
The court’s disposition was twofold: it first rejected Interglass’s motion for clarification (embargos de declaração) relating to the prior decision in case /50000, and then expressly declined to take cognisance of the second appeal filed under case /50001. In Brazilian procedural terminology, the court’s statement that it is ‘not aware’ of the second appeal — ‘NÃO CONHEÇO’ — is a formal declaration of inadmissibility, meaning the appeal was not examined on its merits. The case was closed on 24 June 2025 without a substantive ruling on the validity or infringement of the utility model.
The dismissal of both the clarification motion and the second appeal at the admissibility stage suggests procedural deficiencies in the way the appeals were filed or the applicable appellate routes were pursued, though the public record does not specify the precise ground of inadmissibility. For Interglass, this outcome terminates the appellate track at this level without any vindication of its utility model rights. The absence of a filing date in the public record limits precise duration analysis, and the underlying merits — including any finding on infringement or validity of BRMU1871918U2 — remain unaddressed at this appellate stage.

Appeal dismissed on admissibility: what the ruling means for both parties
Inadmissibility: the court declined to hear the appeal
The Brazilian procedural formula ‘NÃO CONHEÇO’ — ‘I am not aware of’ — is a formal declaration that the appeal does not meet the conditions for the court to examine it on the merits. This is a threshold ruling, not a decision on whether BRMU1871918U2 was infringed or valid. The clarification motion (embargos de declaração) was also separately rejected, removing a common procedural tool used to seek correction or clarification of ambiguities in the prior decision.
Procedural inadmissibilityInterglass loses appellate access without a merits ruling
For Interglass, the dismissal means its utility model rights under BRMU1871918U2 received no appellate vindication. The court’s refusal to admit the second appeal forecloses this particular appellate route. Whether further extraordinary appeals — such as a special appeal to the Superior Tribunal de Justiça — remain available would depend on the specific ground of inadmissibility, which the public record does not disclose. Enforcement of the utility model against Box Elegance is effectively stalled at this stage.
Appellate route closedBox Elegance avoids a merits ruling — but underlying dispute persists
Box Elegance benefits from the dismissal insofar as no appellate finding on infringement was made against it. However, an inadmissibility ruling does not constitute a finding of non-infringement, and the utility model BRMU1871918U2 remains registered. If the lower court’s original decision was adverse to Box Elegance and that decision stands, the dismissal here does nothing to improve its position on the merits. The public record is silent on the lower court’s original findings.
No merits findingUtility model survives — enforcement position remains uncertain
BRMU1871918U2 remains a live registered utility model in Brazil. Competitors and market participants in the glass hardware fittings sector should note that the appeal’s dismissal on procedural grounds does not affect the registration’s validity. Companies manufacturing or distributing holder tube oblong arrangements in the Brazilian market should assess their exposure to this utility model independently of this appellate outcome, as no invalidating finding was made.

Official order — verbatim text
The court’s ruling operates on two levels: rejection of the embargos de declaração and express non-admission of the second appeal. The phrase ‘NÃO CONHEÇO’ is a standard Brazilian appellate formula signalling that the court found the appeal procedurally inadmissible — no review of the merits of the BRMU1871918U2 utility model dispute was conducted. This means the lower court’s decision, whatever its content, remains the operative ruling between the parties. Neither validity nor infringement of the holder tube utility model was adjudicated at this appellate stage.
BRMU1871918U2 — Arrangement for a Holder Tube Oblong
BRMU1871918U2 is a Brazilian utility model — a category of industrial property protection under Brazilian IP law (Law 9,279/1996) that covers functional improvements to existing objects or tools, typically with a shorter term than a full invention patent. The subject matter is an arrangement for a holder tube oblong, consistent with a structural or mounting component used in glass hardware systems such as shower enclosures, glass door fittings, or partition systems. Utility models in Brazil are granted with less stringent inventive step requirements than invention patents, making them a common enforcement tool in hardware and fittings sectors.
The commercial significance of BRMU1871918U2 lies in its application to a component category widely used across architectural glass, shower hardware, and commercial glazing product lines. A utility model covering the geometric arrangement of a holder tube oblong could have broad application to competing product designs, making it a meaningful enforcement asset for Interglass in the Brazilian market. Competitors supplying similar glass fittings or accessories — particularly those importing products with comparable holder tube geometries — face potential exposure. The registration’s continued validity following this procedural dismissal maintains Interglass’s ability to pursue fresh infringement actions.
Should you run an FTO against BRMU1871918U2?
Any company manufacturing, importing, or distributing holder tube oblong arrangements or similar structural glass hardware accessories in Brazil should consider a freedom-to-operate assessment against BRMU1871918U2. The utility model remains registered and enforceable. Product teams developing glass door fittings, shower enclosures, partition hardware, or curtain wall accessories with tubular holder components should verify that their geometries do not fall within the claims of this utility model — particularly given Interglass’s demonstrated willingness to litigate through multiple appellate stages.

What this case signals for the Brazilian glass hardware IP landscape
Procedural dismissals at appellate level leave utility model rights in limbo — and expose both sides to continued commercial uncertainty.
Procedural rigour in Brazilian appeals is critical for utility model holders
The inadmissibility of Interglass’s second appeal suggests that the pathway to appellate review in Brazilian state courts requires strict procedural compliance. Utility model owners asserting rights before the Court of Justice of São Paulo should ensure appeals are filed through the correct procedural vehicle and within applicable time limits to avoid closure without merits review.
An inadmissibility ruling does not resolve commercial risk for either party
Neither party received a definitive ruling on the validity or infringement of BRMU1871918U2. For competitors in the glass hardware accessories market, this means the utility model remains an active potential enforcement risk. Freedom-to-operate analysis against this registration remains advisable for any company producing or importing similar holder tube products into Brazil.
Eireli v Box — key questions answered
‘NÃO CONHEÇO’ is a Brazilian appellate formula meaning the court formally declines to admit the appeal — it is a ruling of procedural inadmissibility, not a decision on the merits. In case 2050156-84.2025.8.26.0000/50001, this means the Court of Justice of São Paulo did not examine whether BRMU1871918U2 was infringed or valid; the second appeal was simply not admitted for review.
Yes. The dismissal of the second appeal on admissibility grounds did not affect the registration status of BRMU1871918U2. The utility model remains a live registration before the INPI. An inadmissibility ruling at the appellate level makes no finding on validity or infringement, leaving the patent’s enforceability unchanged. Interglass retains the right to assert it in fresh proceedings.
Depending on the precise ground of inadmissibility, Interglass may potentially pursue a recurso especial to the Superior Tribunal de Justiça on a federal law question, or explore filing fresh first-instance proceedings. The public record does not disclose why the appeal was inadmissible, which is critical to assessing further options. IP counsel should urgently review the original decision and the basis of the São Paulo court’s non-admission ruling.
Under Brazilian IP Law 9,279/1996, a utility model (modelo de utilidade) protects functional improvements to objects or tools. The inventive step requirement is lower than for invention patents, and the protection term is 15 years from filing. Utility models are commonly used in hardware, mechanical, and fittings sectors. BRMU1871918U2 falls into this category, covering the arrangement of a holder tube oblong used in glass hardware applications.
Yes. Brazilian IP law allows any interested party to file an administrative nullity action (ação de nulidade administrativa) before the INPI against a utility model registration. This route proceeds independently of judicial litigation and, if successful, would extinguish the utility model entirely. Box Elegance or other affected competitors may consider this avenue as an alternative or parallel strategy to the judicial proceedings before the São Paulo courts.
