Singip Glass v Sglass Indústria: Flat Glass Cutting Machine Patent Appeal Dismissed
Singip Glass e Tecnologia Ltda brought proceedings against Sglass Indústria e Comércio de Máquinas Ltda asserting patent BRMU1872914U2, covering a configuration applied to flat glass cutting machines. The Court of Justice of São Paulo denied the provisional remedy sought via interlocutory appeal, bringing this phase of litigation to a close.
Brazilian glass machinery patent dispute ends without provisional relief
Singip Glass e Tecnologia Ltda, a Brazilian glass technology company, initiated proceedings before the Court of Justice of São Paulo against Sglass Indústria e Comércio de Máquinas Ltda, a competitor in the glass machinery manufacturing sector. The dispute centres on patent BRMU1872914U2, a utility model registration covering a configuration applied to flat glass cutting machines. Singip sought an interlocutory provisional remedy — an urgency measure aimed at restricting Sglass’s allegedly infringing commercial activity pending a full merits hearing.
The court denied the provisional measure sought via the interlocutory appeal (agravo de instrumento), as recorded in the verdict: ‘it is denied Provision To aggravation from instrument.’ Under Brazilian civil procedure, an agravo de instrumento is a specific interlocutory appeal challenging a lower court’s interim ruling. The appellate panel’s denial means no emergency injunctive relief was granted at this stage, and the basis of termination confirms the appeal was dismissed. The case was formally closed on 21 January 2025.
Because no filing date is available in the public record, the precise duration of this appeal cannot be confirmed. The denial of provisional relief is consistent with the high threshold Brazilian courts apply to urgent measures in IP disputes, typically requiring a strong prima facie case and demonstrated risk of irreparable harm. Whether underlying merits proceedings remain active at first instance is not determinable from the publicly available record of this appellate case alone.

Appeal dismissed: what the São Paulo court’s ruling means for both parties
Agravo de instrumento denied — no merits adjudication
An agravo de instrumento is a Brazilian procedural vehicle for challenging interlocutory (interim) decisions without waiting for final judgment. The appellate court here denied the provisional measure sought within that appeal, meaning the panel found insufficient grounds to grant emergency relief. Critically, this is a procedural outcome — the court did not rule on whether BRMU1872914U2 is valid or infringed.
Procedural dismissalSingip Glass denied provisional injunction at appellate level
The dismissal of the interlocutory appeal means Singip Glass did not secure the urgent interim relief it sought at this stage. Under Brazilian IP practice, failure to obtain provisional measures does not extinguish the underlying claim. Singip may continue to pursue relief on the merits at first instance, though the denial suggests the court found the urgency or prima facie case threshold was not met on the record presented.
No injunction grantedSglass Indústria free to operate pending any further ruling
With provisional relief denied, Sglass Indústria e Comércio de Máquinas Ltda can continue its flat glass cutting machine activities without court-imposed restrictions arising from this specific appeal. However, this result does not constitute a finding of non-infringement. If first-instance proceedings on the merits remain active, Sglass continues to face litigation risk under BRMU1872914U2.
Operations unrestrained for nowUtility model patents in glass machinery: enforcement landscape
Brazilian utility model registrations like BRMU1872914U2 are typically granted with less substantive examination than invention patents, which can affect the strength of provisional remedy applications. This case suggests competitors in the flat glass cutting machine segment should monitor both the underlying merits proceedings and any renewed provisional applications. Companies operating in this niche should conduct freedom-to-operate assessments against active Brazilian utility model filings.

Official order — verbatim text
The verdict text — ‘it is denied Provision To aggravation from instrument’ — reflects a denial of the provisional measure sought through an interlocutory appeal (agravo de instrumento) under Brazilian civil procedure. This is a procedural ruling confined to the urgency phase; the appellate panel made no determination on the validity of BRMU1872914U2 or whether Sglass Indústria’s products infringe its claims. Both parties’ substantive positions on the patent remain unresolved by this decision.
BRMU1872914U2 — Configuration Applied to Flat Glass Cutting Machine
BRMU1872914U2 is a Brazilian utility model registration protecting a specific configuration applied to flat glass cutting machines. Utility models in Brazil — registered with the INPI — protect three-dimensional forms associated with industrial objects where new shape or arrangement results in functional improvement. The ‘UM’ designation signals this is a utility model rather than an invention patent, meaning it covers a practical configuration of a physical machine rather than an entirely novel process or composition.
Flat glass cutting machines are critical equipment in architectural glazing, automotive glass, and solar panel manufacturing supply chains. A proprietary cutting machine configuration can represent significant competitive advantage in precision, throughput, and yield. The assertion of BRMU1872914U2 against a direct competitor in the same machinery segment suggests Singip Glass regards this configuration as commercially differentiated and defensible. Manufacturers and distributors operating flat glass cutting equipment in Brazil should assess exposure to this registration.
Should you run an FTO against BRMU1872914U2?
Any company manufacturing, importing, or distributing flat glass cutting machines in Brazil should consider whether BRMU1872914U2 poses a freedom-to-operate risk. The active litigation — and the fact the patent holder pursued emergency injunctive relief — signals Singip Glass is prepared to enforce this utility model against competitors. R&D and procurement teams evaluating cutting machine designs for the Brazilian market should prioritise a claim scope review before commercialisation.

What this case signals for the glass machinery IP landscape in Brazil
The São Paulo court’s denial of provisional relief highlights the practical enforcement challenges facing utility model holders in Brazilian industrial machinery disputes.
Provisional relief thresholds are high for utility model patents in Brazil
Brazilian courts typically require clear prima facie validity and demonstrated urgency before granting interim injunctions. Utility model registrations, which undergo lighter examination than invention patents, may face greater scrutiny at the provisional stage. IP holders should build a strong technical and commercial record before seeking emergency relief.
Dismissal of interlocutory appeal does not end the underlying dispute
An agravo de instrumento outcome is confined to the provisional remedy sought. First-instance merits proceedings concerning BRMU1872914U2 may remain active. Competitors and market participants should track subsequent filings at the São Paulo state courts to understand the full scope of ongoing patent risk in the flat glass cutting machine segment.
Ltda v Sglass — key questions answered
The Court of Justice of São Paulo dismissed the interlocutory appeal (agravo de instrumento), denying the provisional measure sought by Singip Glass e Tecnologia Ltda. The case was closed on 21 January 2025. No ruling was made on the merits of the patent infringement claim concerning BRMU1872914U2.
BRMU1872914U2 is a Brazilian utility model registration protecting a specific configuration applied to flat glass cutting machines. Utility models in Brazil cover three-dimensional forms of industrial objects where a new shape or arrangement provides functional improvement, and are registered with the INPI under a lighter examination regime than invention patents.
An agravo de instrumento is a Brazilian procedural mechanism allowing a party to appeal an interlocutory (interim) court decision before final judgment. In patent cases, it is frequently used to challenge a lower court’s grant or refusal of a provisional injunction. Denial of the agravo does not constitute a ruling on patent validity or infringement.
No. The appellate dismissal is a procedural outcome limited to the provisional remedy phase. The court did not adjudicate whether Sglass Indústria’s flat glass cutting machines infringe BRMU1872914U2. If first-instance merits proceedings are ongoing, the infringement question remains open.
Manufacturers and distributors of flat glass cutting machines operating in Brazil should assess whether their product configurations fall within the scope of BRMU1872914U2. The patent holder’s willingness to pursue emergency injunctive relief suggests active enforcement intent. An FTO analysis mapping product design against the utility model’s claims is advisable before commercialising cutting machine configurations in the Brazilian market.
