BBA v. Ênio Bianchi: São Paulo Appeal Dismissed in Vibration Damper Patent Dispute
BBA Sistemas de Envidraçamento Ltda pursued a declaratory judgement against Ênio Bianchi-ME over Brazilian utility model patent BRMU8400847Y1, covering an arrangement for a vibration damper for gap-opening devices. The Court of Justice of São Paulo closed the matter by dismissing the appeal, leaving the lower-court position intact.
Declaratory Judgement Ends at Appeal Stage in São Paulo Utility Model Row
BBA Sistemas de Envidraçamento Ltda initiated case 1044996-33.2018.8.26.0100 before the courts of São Paulo, Brazil, asserting a declaratory judgement claim against Ênio Bianchi-ME. The dispute centres on Brazilian utility model BRMU8400847Y1, which protects an arrangement for a vibration damper designed for devices used in opening gaps — a component category relevant to glazing and façade systems, the market in which BBA operates.
The matter reached the Court of Justice of São Paulo at appeal stage. The appellate court dismissed the appeal in its entirety, a procedural disposition that terminates proceedings at this level without delivering a substantive merits ruling on the validity or infringement of the patent. The dismissal leaves the lower-court outcome as the operative legal position between the parties, though the public record does not detail the terms of that underlying decision.
The case closed on 1 April 2025. The absence of a filed-date figure in the public record means the full litigation duration cannot be confirmed. The appeal dismissal — rather than a considered affirmance or reversal — suggests the appeal may have failed on procedural grounds, a pattern consistent with Brazilian state-court appellate practice. What drove the underlying declaratory action, and whether the utility model’s enforceability was ultimately adjudicated, remains unclear from available public data.

Appeal dismissed: what the São Paulo ruling means for both parties
A dismissed appeal is not a merits verdict
When the Court of Justice of São Paulo dismisses an appeal, it closes the appellate proceeding without examining the substance of the underlying claim. This typically occurs when the appeal fails to meet procedural requirements — such as standing, timeliness, or formal filing conditions. The result is that no appellate court has ruled on whether patent BRMU8400847Y1 is valid or infringed; the lower-court outcome simply stands.
Procedural dismissalDismissal forecloses appellate relief — for now
The party whose appeal was dismissed loses access to the remedy they sought at this appellate level. Depending on which party appealed, they may explore further review at a superior court, but the bar and cost rise considerably. The public record does not specify which party filed the appeal, meaning the downstream commercial impact on BBA or Ênio Bianchi cannot be confirmed with certainty from available data.
No appellate remedy obtainedLower-court result preserved without substantive review
The respondent benefits from the dismissal insofar as the lower-court decision is preserved without appellate interference. However, because the dismissal is procedural rather than substantive, it does not create binding precedent on the validity or scope of BRMU8400847Y1. Future challenges to the utility model — including administrative invalidation routes at the INPI — remain theoretically available to either party.
Lower court position preservedUtility model scope remains judicially untested at appellate level
For glazing and façade component manufacturers operating in Brazil, the dismissal means BRMU8400847Y1 has not been substantively examined by an appellate court. Companies developing vibration damper arrangements for gap-opening devices should note that the patent’s enforceability has not been confirmed or struck down at this level. An INPI administrative challenge or a fresh declaratory action may be the more viable route to definitively resolving the patent’s status.

Official order — verbatim text
The verdict phrase ‘the appeal is dismissed’ confirms a purely procedural closure at the Court of Justice of São Paulo appellate level. No substantive finding on the validity, scope, or infringement of BRMU8400847Y1 is recorded. For BBA Sistemas de Envidraçamento and Ênio Bianchi-ME alike, this means the declaratory judgement dispute has not been resolved on its merits at appeal — the lower-court position governs, but remains unreported in the available public record.
BRMU8400847Y1 — Vibration Damper Arrangement for Gap-Opening Devices
BRMU8400847Y1 is a Brazilian utility model — a form of industrial property protection designed for incremental functional improvements to existing products or processes, offering a faster grant path than a full invention patent. The patent covers an arrangement for a vibration damper integrated into a device for opening gaps, a component category consistent with sliding or pivoting glazing panels, façade actuators, or similar architectural hardware. Utility models in Brazil are granted by the INPI and carry a ten-year term from filing.
For the glazing and architectural hardware sector in Brazil, a utility model protecting a damper arrangement can carry meaningful commercial weight if it covers a configuration widely adopted across façade systems. The involvement of BBA Sistemas de Envidraçamento — a specialist in glazing systems — as the declaratory plaintiff suggests the patent may cover or read upon components used in commercially active product lines. Competitors and OEMs supplying vibration-damping hardware for gap-opening devices in Brazil should assess their exposure to this utility model before entering or expanding in the market.
Should you run an FTO analysis against BRMU8400847Y1?
Any company designing, importing, or distributing vibration damper arrangements for gap-opening devices in Brazil should treat BRMU8400847Y1 as a live FTO concern. The patent has not been invalidated by a Brazilian court or the INPI on the available record. The existence of a declaratory judgement action brought by a market participant — BBA Sistemas de Envidraçamento — confirms that at least one commercial operator regarded the patent as a potential barrier to freedom of operation. Glazing hardware manufacturers, façade system integrators, and their component suppliers are the most directly exposed parties.

What this case signals for the Brazilian glazing and façade IP landscape
A procedurally dismissed appeal leaves patent enforceability unresolved — a risk that compounds for competitors and potential licensees in the Brazilian market.
Procedural dismissals in Brazil do not extinguish patent risk
An appeal dismissal by the Court of Justice of São Paulo leaves the underlying utility model in force and judicially unchallenged at appellate level. For companies in the glazing or façade hardware space, BRMU8400847Y1 retains its presumptive validity. An INPI administrative nullity action may offer a more direct path to clearing the patent than relying on ongoing litigation outcomes.
Declaratory judgement actions signal active freedom-to-operate concern
The choice of a declaratory judgement cause of action typically suggests that the plaintiff sought court confirmation of non-infringement or invalidity — implying a real commercial conflict over the vibration damper arrangement. R&D and product teams developing components for gap-opening systems in Brazil should treat this patent as a live FTO concern until definitively resolved.
Bba v Ênio — key questions answered
The Court of Justice of São Paulo dismissed the appeal on procedural grounds, meaning no substantive ruling was made on the validity or infringement of utility model BRMU8400847Y1. The lower-court outcome is preserved, but no appellate merits analysis was conducted.
BRMU8400847Y1 is a Brazilian utility model granted by the INPI covering an arrangement for a vibration damper for a device for opening gaps. It is relevant to glazing panels, façade actuators, and similar architectural hardware components that incorporate vibration-damping elements.
Yes. A procedural dismissal of an appeal does not adjudicate patent validity. The INPI administrative nullity action route remains available to any interested party. A fresh declaratory action before the Brazilian courts is also theoretically possible, subject to procedural and standing requirements.
In Brazilian law, a declaratory judgement action (ação declaratória) allows a party to seek a court declaration confirming a specific legal relationship — such as non-infringement of a patent or the invalidity of a utility model. It is commonly used by manufacturers who face patent risk but have not yet been sued, to proactively clarify their freedom to operate.
The plaintiff is BBA Sistemas de Envidraçamento Ltda, a Brazilian glazing and façade systems company. The defendant is Ênio Bianchi-ME, a Brazilian micro-enterprise. The dispute concerns utility model BRMU8400847Y1 and was pursued as a declaratory judgement action before the São Paulo state courts.
