Belazza v. Plásticos Novel São Paulo — Appeal Dismissed in Transport Box Patent Case
Belazza Empreendimentos e Participações brought an infringement action against Plásticos Novel São Paulo Ltda over Brazilian utility model patent BRMU2113759U2, covering transport boxes with PN-ALC lids across three product models. The Court of Justice of São Paulo dismissed the appeal, finding the requirements for interim relief under Article 300 of the Brazilian Civil Procedure Code were not met.
Appeal dismissed as São Paulo court finds no basis for interim relief
Belazza Empreendimentos e Participações, the plaintiff and apparent holder of Brazilian utility model patent BRMU2113759U2, initiated an infringement action against Plásticos Novel São Paulo Ltda before the Court of Justice of São Paulo (case no. 2229590-04.2023.8.26.0000). The dispute centres on three specific product models — transport boxes with PN-ALC lids designated 6425, 6432, and 6437 — which Belazza alleged fell within the scope of its registered utility model.
The case closed on 24 January 2024 when the Court of Justice of São Paulo dismissed the appeal. The court’s reasoning expressly references Article 300 of the Brazilian Code of Civil Procedure (CPC), which governs the grant of preliminary injunctions, finding that the statutory requirements for such relief were not satisfied. The dismissal on appeal confirms the lower court’s refusal to maintain interim measures, leaving the defendant’s commercial activities unrestrained pending any further proceedings.
The resolution is notable for its procedural posture: the outcome turns on interim relief criteria rather than a final merits determination on infringement, meaning the substantive question of whether the PN-ALC lid models infringe BRMU2113759U2 remains publicly unresolved. It is unclear from the available record whether Belazza pursued parallel proceedings on the merits. Early dismissal at the injunction stage is consistent with Brazilian courts’ strict interpretation of Article 300’s probability-of-right and risk-of-harm thresholds.

Appeal dismissed: what the Article 300 CPC finding means for both parties
Article 300 CPC: Brazil’s threshold for preliminary injunctions
Article 300 of the Brazilian CPC requires a claimant seeking interim relief to demonstrate a likely right (fumus boni iuris) and a risk of harm if relief is not granted (periculum in mora). The court found these elements absent. This is a procedural outcome — it does not constitute a final ruling on whether infringement of BRMU2113759U2 actually occurred.
Procedural — not a merits rulingDismissed on appeal — lower court refusal upheld
The ‘Appeal Dismissed’ basis of termination confirms the appellate chamber of the Court of Justice of São Paulo agreed with the first-instance refusal to grant or maintain interim relief. For the defendant, Plásticos Novel São Paulo, this outcome removes the immediate threat of an injunction halting production or sales of the disputed transport box models. However, it does not necessarily foreclose a separate merits-based infringement action by Belazza.
Defendant’s position preservedUtility model protection under Brazilian IP law
BRMU2113759U2 is a Brazilian utility model registration — a form of IP protection under Law No. 9.279/1996 that covers functional improvements to existing objects rather than wholly new inventions. Utility models in Brazil have a 15-year term from filing. The ‘U2’ suffix designates a granted utility model. This classification is relevant to assessing claim scope when evaluating infringement against competing transport box designs.
Brazilian utility model — Lei 9.279/1996Plásticos Novel can continue selling the disputed models for now
With the appeal dismissed and no injunction in place, Plásticos Novel São Paulo faces no court-imposed restriction on manufacturing or distributing transport box models 6425, 6432, and 6437 as a result of this specific proceeding. Belazza’s ability to secure market protection for its PN-ALC lid design now depends on whether it can mount a stronger merits case or pursue alternative enforcement channels through INPI or separate litigation.

Stipulation of dismissal — official text
The court’s dismissal language — ‘in the absence of the requirements provided for in article 300, CPC, the maintenance of the decision is rigorous’ — confirms this is a procedural ruling on interim relief, not a substantive finding on patent infringement. The phrase ‘maintenance of the decision’ indicates the appellate panel was reviewing a lower court order, which it upheld. Neither party received a merits determination: the defendant gains relief from injunctive pressure, but the plaintiff retains the right to pursue full infringement proceedings on BRMU2113759U2.
BRMU2113759U2 — Brazilian utility model for transport boxes with PN-ALC lids
BRMU2113759U2 is a Brazilian utility model registration — denoted by the ‘MU’ prefix and ‘U2’ grant suffix — filed and granted under Brazil’s Industrial Property Law (Lei 9.279/1996). Utility models in Brazil protect functional improvements to objects rather than entirely novel inventions, and carry a 15-year term from the filing date. This registration specifically covers a transport box design incorporating what is designated a PN-ALC lid, applied across at least three commercial models (6425, 6432, 6437), suggesting a product line with distinct size or capacity variants sharing a common lid mechanism.
For the Brazilian packaging and plastics sector, utility model registrations on container and lid systems represent a key competitive differentiator. If BRMU2113759U2’s claims are broadly drafted to cover the lid-attachment or sealing mechanism — rather than purely aesthetic features — competing manufacturers of lidded transport boxes face meaningful freedom-to-operate risk. The litigation against Plásticos Novel São Paulo signals that Belazza is prepared to enforce this registration commercially, making it a patent warranting close attention by any company active in the Brazilian transport packaging market.
Should your team run an FTO against BRMU2113759U2?
Any Brazilian manufacturer, importer, or distributor of lidded transport boxes — particularly those offering multiple size variants under a common lid system — should evaluate their exposure to BRMU2113759U2. The fact that Belazza specifically identified three model numbers in its infringement action suggests the registered claims may be tightly mapped to lid geometry or attachment features that recur across product families. If your product range includes boxes with removable or snap-fit lids in the transport and logistics category, an FTO analysis is warranted before scaling distribution in Brazil.

What this case signals for the Brazilian packaging and plastics IP landscape
A dismissed appeal on interim relief is not a clean win for defendants — it leaves IP exposure unresolved and enforcement risk alive.
Interim injunction failures do not end Brazilian patent disputes
Brazilian courts apply a strict two-limb test under Article 300 CPC. Failure at the injunction stage — as here — does not bar a subsequent full merits action. Patent holders in the packaging sector should treat an Article 300 dismissal as a procedural setback, not a final clearance. Competitors watching this case should not assume Plásticos Novel holds a definitive non-infringement determination.
Utility model scope is the core battleground in Brazilian packaging IP
Brazilian utility model registrations covering lid and container designs are increasingly litigated as packaging manufacturers seek design differentiation. BRMU2113759U2’s claim scope — specifically what constitutes a PN-ALC lid — will be central to any future merits hearing. Competitors in the transport box segment should map their designs against the registered claims, not just the product models named in this action.
BELAZZA v PLASTICOS — key questions answered
The appeal was dismissed by the Court of Justice of São Paulo on 24 January 2024. The court found that the requirements of Article 300 of the Brazilian CPC — governing preliminary injunctions — were not met. This is a procedural ruling on interim relief and does not constitute a final merits determination on whether patent BRMU2113759U2 was infringed.
The patent at issue is BRMU2113759U2, a Brazilian utility model registration. It covers transport boxes with a PN-ALC lid design, specifically applied to product models 6425, 6432, and 6437 manufactured by Plásticos Novel São Paulo Ltda. Utility models in Brazil are protected under Lei 9.279/1996 for up to 15 years from filing.
Article 300 of Brazil’s Code of Civil Procedure sets the conditions for granting provisional or interim injunctive relief. It requires the claimant to show a probable right (fumus boni iuris) and risk of irreparable harm (periculum in mora). The court found Belazza failed to satisfy these thresholds, resulting in dismissal of the appeal. The underlying infringement question on the merits was not decided.
A dismissal at the interim relief stage under Article 300 CPC does not bar Belazza from pursuing a full merits-based infringement action regarding BRMU2113759U2. The public record of this case does not indicate whether parallel proceedings are ongoing. Patent holders in Brazil routinely pursue merits actions independently of injunction applications.
A Brazilian utility model (Modelo de Utilidade) protects functional improvements to existing objects rather than entirely novel inventions. Governed by Lei 9.279/1996, utility models carry a 15-year term from filing and typically have a lower inventive step threshold than invention patents. BRMU2113759U2 is a granted utility model, indicated by the ‘MU’ prefix and ‘U2’ suffix in the registration number.
