Cerâmica Santa Marta v. Miranda: Ceramic Planter Block Patent Survives Invalidity Appeal
Cerâmica Santa Marta Ltda challenged the validity of Brazilian patent BRPI0904145A2, covering modular ceramic blocks for vertical planters and civil construction. The Court of Justice of São Paulo dismissed the appeal, leaving the patent intact and its holder’s rights fully enforceable.
Ceramic block patent survives São Paulo appellate challenge
Cerâmica Santa Marta Ltda, a Brazilian ceramics manufacturer, brought an invalidity and cancellation action against Pedro Bueno de Miranda, the holder of patent application BRPI0904145A2. The patent covers a modular block system designed for composing vertical planters, with broader applicability to ceramic blocks used in civil construction and decoration. The dispute was heard before the Court of Justice of São Paulo under case number 1008081-96.2017.8.26.0624.
The proceeding concluded on 13 May 2024, when the court issued a ruling dismissing the appeal brought by Cerâmica Santa Marta. The basis of termination is recorded as ‘Patent Upheld,’ indicating that the appellate panel found no grounds to disturb the validity of BRPI0904145A2. For the patent holder, Pedro Bueno de Miranda, the ruling preserves the exclusivity conferred by the patent. For Cerâmica Santa Marta, the dismissal closes this avenue of challenge, at least at the state appellate level.
The case record does not disclose the original filing date, making it impossible to calculate the full litigation duration. What the public record does confirm is that the invalidity action ultimately failed, consistent with appellate courts’ general tendency to require clear and convincing grounds before disturbing a granted patent. Whether Cerâmica Santa Marta retains further avenues — such as an administrative challenge before the INPI — is not addressed in the available case data.

São Paulo court dismisses appeal: what the ruling means for both parties
Appeal dismissed: the lower validity finding stands
A dismissal of an invalidity appeal means the appellate court found no reversible error in the proceeding below sufficient to warrant cancellation of the patent. The court did not conduct a fresh merits assessment — rather, it confirmed that the challenger failed to meet the burden required to overturn the patent’s validity. The patent BRPI0904145A2 continues in force with the same legal standing it held before the appeal was filed.
Patent survives challengeMiranda’s patent rights fully preserved post-appeal
For Pedro Bueno de Miranda, the dismissal is a complete vindication of the patent’s validity. BRPI0904145A2 remains enforceable against third parties, including — in principle — Cerâmica Santa Marta itself. The ruling strengthens the patent holder’s commercial position in the modular ceramic block and vertical planter market, and any future infringement action may proceed on the basis of a patent that has now withstood appellate scrutiny.
Enforceability confirmedCerâmica Santa Marta’s invalidity route closed at this level
The dismissal forecloses the state appellate challenge for Cerâmica Santa Marta. The company may still face exposure to infringement claims if its ceramic block products fall within the scope of BRPI0904145A2. Alternative routes — such as a direct administrative nullity proceeding before Brazil’s INPI — may remain theoretically available, but the failure here raises the practical bar for any renewed challenge. The public record does not indicate whether further review is being sought.
Appellate avenue exhaustedStronger IP position for decorative ceramic block innovations
The outcome suggests the Brazilian judicial system will uphold registered ceramic construction and decoration patents where invalidity grounds are not compellingly demonstrated. For the broader civil construction ceramics sector, the ruling signals that modular planter block designs with granted patent protection carry meaningful enforceability risk for competitors. Companies operating in overlapping product categories should assess their exposure to BRPI0904145A2 before scaling manufacture or distribution.

Official order — verbatim text
The court’s ruling — ‘I DISMISS the appeal’ — is a procedural and substantive confirmation that the appellate panel found insufficient grounds to invalidate or cancel patent BRPI0904145A2. In the Brazilian appellate context, dismissal of an invalidity appeal without a merits reversal means the lower-level validity determination stands undisturbed. The basis of termination, recorded as ‘Patent Upheld,’ reinforces that the court did not merely reject the appeal on procedural grounds but affirmed the patent’s continued legal standing. For the patent holder, this creates a stronger enforcement posture. For Cerâmica Santa Marta, the ruling consistent with appellate deference to granted patent rights absent clear invalidity evidence.
BRPI0904145A2 — Modular Ceramic Blocks for Vertical Planters
BRPI0904145A2 is a Brazilian patent application covering a modular block system specifically designed for the composition of vertical planters, with broader utility in ceramic blocks for civil construction and decoration. The patent captures a structural and aesthetic design solution in the ceramics space, likely addressing how individual ceramic units interlock or assemble to form vertical growing structures. The ‘BRPI’ prefix indicates a national phase Brazilian patent application, and the ‘0904’ segment suggests a 2009 filing year, placing the invention in the period of rising interest in urban greening and modular construction components.
The strategic significance of BRPI0904145A2 lies in its intersection of two commercially active markets: civil construction ceramics and decorative urban horticulture products. A patent that covers both the construction application and the decorative planter use case creates a broad enforcement perimeter. For ceramic block manufacturers like Cerâmica Santa Marta, any product line touching modular vertical planter assemblies risks falling within the patent’s claims. The patent’s survival of appellate challenge further elevates its commercial weight, making it a material IP asset in the Brazilian construction ceramics market.
Should your product team run an FTO against BRPI0904145A2?
Any Brazilian manufacturer, importer, or distributor of modular ceramic blocks — particularly those marketed for vertical gardens, living walls, or decorative civil construction applications — should treat BRPI0904145A2 as a live risk. The patent has now survived a direct invalidity challenge, meaning it carries appellate-confirmed validity. Product teams commercialising modular planter systems or decorative ceramic construction units in Brazil should commission a formal freedom-to-operate analysis before scaling production or entering new distribution channels.

What this case signals for the ceramic construction IP landscape in Brazil
A dismissed invalidity appeal before São Paulo’s Court of Justice strengthens design patent positions in the Brazilian ceramics and civil construction sector.
Patent holders in ceramics should document prior art proactively
The dismissal of Cerâmica Santa Marta’s challenge suggests that broadly framed invalidity arguments are unlikely to succeed at the appellate level without specific, well-evidenced prior art. Patent holders in the ceramic block and construction materials space should nonetheless maintain robust prosecution files to withstand future challenges, whether judicial or administrative before INPI.
Manufacturers must run FTO checks on modular construction ceramics
BRPI0904145A2 now carries appellate-confirmed validity. Any ceramics manufacturer producing modular blocks for vertical planters or decorative civil construction applications in Brazil faces genuine infringement exposure. An FTO analysis scoped to this patent — and any continuation or family members — should be a near-term priority for affected companies.
LTDA v PEDRO — key questions answered
The Court of Justice of São Paulo dismissed Cerâmica Santa Marta’s invalidity appeal, upholding patent BRPI0904145A2. The basis of termination is recorded as ‘Patent Upheld,’ confirming that the patent covering modular ceramic blocks for vertical planters remains valid and enforceable as of 13 May 2024.
BRPI0904145A2 is a Brazilian patent application covering a modular block system for composing vertical planters, with broader application to ceramic blocks used in civil construction and decoration. The ‘0904’ identifier suggests a 2009 filing year. The patent survived an invalidity challenge before the São Paulo Court of Justice in case 1008081-96.2017.8.26.0624.
The dismissal closes the state appellate avenue. However, under Brazilian IP law, a direct administrative nullity action before the INPI may remain a separate and independent avenue. Such proceedings are not bound by judicial decisions on validity, though they require demonstrating specific grounds for cancellation and can take considerable time to resolve. The public case record does not indicate whether further action is being pursued.
A ‘Patent Upheld’ termination in the context of a Brazilian invalidity or cancellation action means the court declined to cancel the patent, leaving it in full legal force. In appellate proceedings, this typically reflects the panel’s finding that the challenger failed to establish sufficient grounds — such as lack of novelty or inventive step — to overcome the presumption of validity afforded to a granted patent.
Yes, particularly for manufacturers or distributors of modular ceramic blocks designed for vertical planters, living walls, or decorative civil construction. The patent has now withstood a judicial invalidity challenge, strengthening its enforceability. Companies whose products may fall within the patent’s claim scope should commission a freedom-to-operate analysis and consider design-around strategies before scaling operations in the Brazilian market.
