Bianchi v. Brazilian Kits: Appeal Dismissed in Vibration Damper Patent Dispute
Enio Bianchi pursued a declaratory judgement action against Brazilian Kits Indústria de Acessórios para Vidros Ltda before the Court of Justice of São Paulo, centring on patent BRMU8400847Y1 — an arrangement for a vibration damper used in gap-opening devices. The appeal was dismissed, bringing the litigation to a close on 21 January 2025.
Declaratory action over vibration damper patent ends at appeal stage
This dispute arose before the Court of Justice of São Paulo (Case No. 1006941-32.2018.8.26.0223) and pitted individual patent holder Enio Bianchi against Brazilian Kits Indústria de Acessórios para Vidros Ltda, a manufacturer of accessories for glass products. The central patent at issue is BRMU8400847Y1, which protects an arrangement for a vibration damper designed for devices used in opening gaps — a component category relevant to automotive and architectural glazing accessory markets. The action was framed as a declaratory judgement, suggesting one party sought a judicial declaration regarding the patent’s validity, scope, or ownership rather than seeking damages at the outset.
The case closed on 21 January 2025 when the Court of Justice of São Paulo dismissed the appeal. The dismissal at appellate level — captured in the verdict as ‘I DISMISS the appeal’ — means the court declined to adjudicate the substance of the appeal, leaving the lower court’s position as the operative outcome. A dismissal of this kind does not constitute a ruling on the merits of the underlying declaratory judgement claim; it terminates appellate review on procedural or standing grounds without vindicating either party’s substantive position on the patent.
Without a recorded filing date, the total duration of proceedings cannot be confirmed from the public record. The fact that the matter reached appellate review before being dismissed suggests the dispute progressed through at least one prior hearing or decision, though the basis for the appeal’s dismissal — whether procedural deficiency, lack of standing, or untimeliness — is not detailed in the available case data. What remains unknown is whether the lower court’s underlying ruling on the declaratory judgement has res judicata effect and whether either party may seek further review or pursue parallel proceedings.

Appeal dismissed: what the ruling means for both parties
Appeal dismissal ends review without a merits ruling
When an appellate court dismisses an appeal — as the Court of Justice of São Paulo did here — it declines to examine the substantive arguments raised on appeal. The dismissal is procedural: the court found a reason not to proceed, which may include untimely filing, failure to satisfy formal requirements, or lack of appellate standing. No new ruling on the patent’s validity or scope was issued; the lower court record stands as-is.
Procedural dismissalBianchi retains whatever position the lower court established
For Enio Bianchi, the appeal’s dismissal means that whatever outcome was reached at the lower court level remains in place. If the lower ruling was favourable, that position is preserved. If unfavourable, the dismissal forecloses appellate relief — at least through this route. The patent BRMU8400847Y1 remains registered, but the public record does not confirm whether its enforceability was challenged or confirmed in the lower proceedings.
Lower court position preservedBrazilian Kits faces no new adverse ruling from this appeal
Brazilian Kits benefits from the absence of an appellate merits ruling: no new declaration on patent rights was made against it at this stage. However, if the lower court issued a declaratory judgement affecting the company’s ability to operate freely around BRMU8400847Y1, that ruling remains operative. The dismissal does not itself provide Brazilian Kits with a freedom-to-operate finding.
No new appellate liabilityUncertainty around vibration damper IP persists for glass accessory makers
The absence of a substantive appellate ruling means the commercial boundaries of BRMU8400847Y1 have not been authoritatively redrawn. Manufacturers of vibration damper arrangements for gap-opening devices — particularly in Brazil’s automotive glazing and architectural glass accessory sector — should treat this outcome as inconclusive. Companies operating in adjacent product spaces should monitor further proceedings and conduct FTO analysis before launching products that could overlap with the patent’s claims.

Official order — verbatim text
The verdict phrase ‘I DISMISS the appeal’ is unambiguous as to procedural outcome but silent on substantive merit. At the appellate level of the Court of Justice of São Paulo, such a dismissal typically indicates a failure to satisfy procedural admissibility requirements — such as timeliness, standing, or formal compliance — rather than a substantive rejection of the appealing party’s arguments. This means neither party received a judicial determination on the underlying declaratory judgement claims concerning BRMU8400847Y1. The lower court’s ruling, whatever its content, is left undisturbed and operative as between the parties.
BRMU8400847Y1 — vibration damper arrangement for gap-opening devices
BRMU8400847Y1 is a Brazilian utility model patent protecting an arrangement for a vibration damper specifically designed for devices that open gaps — most plausibly window or door opening mechanisms used in automotive or architectural glazing contexts. Brazilian utility models (designated by the ‘MU’ prefix) protect functional improvements to objects of practical use and have a maximum term of 15 years from filing. The utility model route requires a lower level of inventive step than a full invention patent, making it a commercially practical tool for protecting incremental product improvements in the hardware and accessories space.
For competitors in Brazil’s glass accessory and automotive glazing hardware market, BRMU8400847Y1 represents a registered IP right that its holder, Enio Bianchi, has been willing to assert through litigation. The declaratory judgement framing of this case suggests a competitor sought judicial clarity on whether their product or business activity fell within the patent’s scope — a pattern consistent with genuine commercial overlap. Companies designing, importing, or distributing vibration damper arrangements for gap-opening devices in Brazil should treat this patent as an active risk and assess design-around or challenge options accordingly.
Should you run an FTO against BRMU8400847Y1?
If your company manufactures, imports, or distributes vibration damper components for window or door opening devices — particularly for the automotive glazing or architectural hardware segment in Brazil — BRMU8400847Y1 is a directly relevant IP risk. The fact that this patent has been the subject of active litigation, including an appeal dismissed as recently as January 2025, confirms that the right is monitored and asserted. Product teams and procurement managers sourcing damper arrangements for the Brazilian market should commission an FTO before product launch or commercial scaling.

What this case signals for the Brazilian glass accessories IP landscape
A dismissed appeal leaves the patent landscape around vibration damper arrangements unresolved — a commercial signal worth tracking.
Procedural dismissals do not confirm patent enforceability
The appeal’s dismissal issued no merits finding on BRMU8400847Y1. Companies in Brazil’s glazing accessory market should not interpret this outcome as a green light: the patent remains registered and potentially enforceable. Conducting a targeted FTO analysis against the patent’s Brazilian utility model claims is the prudent next step before product launch or expansion.
Declaratory judgement actions signal active competitive pressure
The choice of a declaratory judgement vehicle — rather than direct infringement — typically suggests the defending party sought pre-emptive legal certainty, consistent with a commercial dispute over product overlap. For R&D and product teams in the glass hardware and damper accessory space, this pattern indicates that BRMU8400847Y1 is actively asserted and monitored by its holder.
BIANCHI v BRAZILIAN — key questions answered
The Court of Justice of São Paulo dismissed the appeal in a declaratory judgement action brought by Enio Bianchi against Brazilian Kits Indústria de Acessórios para Vidros Ltda. The case concerned patent BRMU8400847Y1, covering an arrangement for a vibration damper for gap-opening devices. The dismissal was procedural — no merits ruling on the patent was issued at appellate level. The case closed on 21 January 2025.
BRMU8400847Y1 is a Brazilian utility model patent protecting an arrangement for a vibration damper for devices used in opening gaps, such as window or door mechanisms. The patent remains a registered right; the dismissal of this appeal did not cancel or limit its enforceability. Parties in adjacent product spaces should conduct FTO analysis to assess current claim scope and remaining term.
A dismissal of an appeal by the Court of Justice of São Paulo without merits review means the lower court’s decision remains operative. The appellate court found the appeal inadmissible — typically on procedural grounds such as untimeliness or standing — without examining the substantive arguments. This outcome does not confirm the patent’s validity or invalidity; it simply ends the appellate phase of this particular case.
Declaratory judgement actions are typically used when a party seeks pre-emptive judicial confirmation that its conduct does not infringe a patent, or to challenge a patent’s validity before an infringement suit is filed. In this case, the declaratory framing suggests that either Bianchi or Brazilian Kits sought clarity on the scope or ownership of BRMU8400847Y1 in a context of commercial overlap, rather than responding to an existing infringement claim. The precise grounds are not detailed in the available public record.
The dismissal of this appeal does not bar Brazilian Kits from pursuing alternative challenge routes. Under Brazilian IP law (Law No. 9,279/1996), third parties may file an administrative nullity action (processo administrativo de nulidade) before INPI against a utility model patent, or bring a judicial nullity action in federal court. These routes are independent of the São Paulo state court proceedings and may offer a more direct path to invalidating or limiting the patent’s claims.
