Box Elegance v Interglass: Mounting Profile Patent Appeal Dismissed
Box Elegance Ltda brought an infringement action against Interglass Comercio de Ferragens e Acessórios para Vidros Eireli over utility model patent BRMU1202835U2, covering an arrangement for a mounting profile for box. The Court of Justice of São Paulo dismissed the interlocutory appeal, with legal fees increased to R$ 6,500.00, closing the matter on 29 May 2024.
Procedural dismissal ends mounting profile infringement dispute in São Paulo
Box Elegance Ltda, the plaintiff and apparent holder of Brazilian utility model BRMU1202835U2 covering an arrangement for a mounting profile for box, initiated an infringement action against Interglass Comercio de Ferragens e Acessórios para Vidros Eireli before the Court of Justice of São Paulo (Case No. 1028666-19.2022.8.26.0100). The dispute centres on a hardware and fittings product category used in glass installation and framing applications, a niche but commercially sensitive segment of the building materials supply chain.
The case was resolved on procedural grounds rather than on the merits of the infringement claim. The court found that the filing of an interlocutory appeal did not suspend the deadline for amendment, which had expired on 5 February 2022. On that basis, the court dismissed the appeal and increased the loss fees payable to R$ 6,500.00, signalling that the appellate challenge was considered without sufficient procedural foundation. The underlying first-instance decision was upheld on its own legal grounds.
The dismissal on procedural grounds means the substantive question of whether Interglass infringed BRMU1202835U2 was not adjudicated at appellate level, leaving the merits unresolved in any publicly available appellate record. The fee uplift to R$ 6,500.00 suggests the court viewed the appeal as adding unnecessary delay. What drove the original first-instance outcome and whether Box Elegance secured any injunctive or monetary relief at that stage is not determinable from the public appellate record alone.

Appeal dismissed on procedural grounds: what the ruling means for both parties
Procedural bar: missed amendment deadline sinks the appeal
The Court of Justice of São Paulo dismissed the interlocutory appeal because the deadline for amendment had already lapsed on 5 February 2022. Brazilian procedural law does not allow the mere filing of an interlocutory appeal to toll or suspend such deadlines. The court therefore declined to examine the substance of the appeal, dismissing it entirely and affirming the lower decision on its own legal grounds. No merits ruling was issued at this appellate stage.
Procedural dismissal — no merits reviewedInterglass loses appellate route with costs increased against it
The dismissal of the appeal, combined with an increase in loss fees to R$ 6,500.00, is a commercially adverse outcome for Interglass as appellant. The fee uplift typically signals judicial disapproval of the appellate strategy employed. Interglass is now bound by the first-instance decision without having secured any appellate review of the infringement findings. Further appeal options, if any remain under Brazilian civil procedure, would require new procedural grounds.
Appellant — fees increased, appeal route closedBox Elegance retains first-instance position without appellate reversal
Box Elegance, as the patent holder and appellee, benefits from the dismissal insofar as the first-instance decision in its favour remains intact and unchallenged on the merits. The appellate court’s confirmation that the lower ruling stands ‘on its own legal grounds’ reinforces the enforceability of whatever relief was granted below. However, the public appellate record does not specify the scope of the original relief, which limits visibility into the full commercial impact for Box Elegance.
Appellee — first-instance position preservedUtility model enforcement in Brazilian glass fittings sector: key signal
This case illustrates that Brazilian utility model patents covering niche hardware components such as mounting profiles can form the basis of active enforcement actions before the Court of Justice of São Paulo. Competitors in the glass fittings and hardware sector should treat utility model filings as genuine enforcement tools, not merely defensive instruments. The procedural dismissal also highlights the risks of interlocutory appeals in Brazilian civil proceedings where amendment deadlines are strictly observed.

Official order — verbatim text
The court’s dismissal language — ‘the mere filing of the interlocutory appeal did not prevent the expiration of the deadline’ — is a strict procedural ruling, not a comment on the substantive infringement merits. By upholding the lower decision ‘on its own legal grounds,’ the appellate panel neither endorsed nor scrutinised the first-instance infringement findings. The fee increase to R$ 6,500.00 suggests the appeal was viewed as lacking procedural justification, which may limit the appellant’s credibility in any further challenge.
BRMU1202835U2 — Arrangement for a mounting profile for box
BRMU1202835U2 is a Brazilian utility model patent covering an arrangement for a mounting profile for box — a hardware component relevant to glass installation, framing, and enclosure assemblies. Brazilian utility models (modelo de utilidade) protect functional improvements to objects or parts of objects, offering a lower inventive step threshold than invention patents but providing enforceable IP rights for up to 15 years from filing. The ‘U2’ suffix indicates a granted utility model registration at the INPI (Instituto Nacional da Propriedade Industrial).
In the glass hardware and fittings sector, mounting profiles and box arrangements are critical interface components between glazing panels and their supporting structures. A utility model covering such a profile can create a meaningful exclusivity zone for the rights holder if the claimed configuration is widely adopted in the trade. The fact that Box Elegance pursued active litigation — and prevailed at first instance — suggests the patent covers a commercially relevant configuration, not merely a design variant. Competitors supplying glass fittings, enclosure hardware, or related accessories into the Brazilian market should treat this registration as a live enforcement risk.
Should you run an FTO against BRMU1202835U2?
Any company manufacturing, importing, or distributing mounting profiles, box arrangements, or related glass fitting hardware in Brazil should assess its exposure to BRMU1202835U2. The successful enforcement at first instance — and the procedural dismissal of the appellant’s challenge — means the patent holder retains an uncontested enforcement position. R&D and procurement teams designing or sourcing profile systems for glass enclosures, shower cabinets, or architectural glazing applications face the most direct risk.

What this case signals for the glass hardware and fittings IP landscape
A procedural dismissal in São Paulo’s courts carries real commercial weight for hardware manufacturers and distributors active in the Brazilian market.
Brazilian utility models are active enforcement tools — monitor them
BRMU1202835U2 demonstrates that utility model registrations covering relatively narrow hardware configurations — such as mounting profiles for box assemblies — are being deployed in active infringement litigation before Brazilian state courts. Companies sourcing or distributing glass fittings in Brazil should audit their product ranges against relevant utility model filings.
Procedural deadlines in Brazilian civil procedure are strictly enforced
The dismissal turned entirely on a missed amendment deadline of 5 February 2022. Brazilian courts have consistently held that interlocutory appeals do not suspend procedural timelines unless the law expressly provides otherwise. IP litigants and their counsel must map deadline exposure from the outset of any Brazilian infringement proceeding.
Ltda v Interglass — key questions answered
The Court of Justice of São Paulo dismissed the interlocutory appeal filed in this case, closing the matter on 29 May 2024. The dismissal was procedural: the court found that the filing of the appeal had not suspended the amendment deadline, which had expired on 5 February 2022. The first-instance decision was upheld and loss fees were increased to R$ 6,500.00.
BRMU1202835U2 is a Brazilian utility model (modelo de utilidade) registered at the INPI covering an arrangement for a mounting profile for box — a hardware component used in glass installation and framing systems. Brazilian utility models protect functional improvements to objects with a lower inventive step threshold than invention patents, and are enforceable for up to 15 years from the filing date.
The appeal was dismissed on procedural grounds. The Court of Justice of São Paulo held that the mere filing of an interlocutory appeal does not toll or suspend the deadline for amendment under Brazilian civil procedure. Since the amendment deadline had already expired on 5 February 2022, the court declined to review the appeal on its merits and dismissed it, upholding the lower decision on its own legal grounds.
The case signals that Brazilian utility model patents covering niche hardware configurations — including mounting profiles for glass enclosures — are active enforcement tools. Distributors and manufacturers operating in Brazil’s glass hardware sector should audit their product ranges against BRMU1202835U2 and related INPI filings. The uncontested first-instance outcome means Box Elegance retains an unreviewed enforcement position, which may embolden further enforcement actions.
Not definitively at appellate level. The appeal was dismissed on procedural grounds — the court did not review or affirm the infringement merits. The first-instance decision, which presumably addressed infringement, was upheld ‘on its own legal grounds,’ but the appellate record does not publish or endorse those findings substantively. The merits of the infringement claim were therefore not adjudicated by the Court of Justice of São Paulo in this appellate ruling.
