Lorenzo v. Tecnoblu: Declaratory Appeal Rejected in Digital-Image Braces Patent Dispute
Ricardo Augusto de Lorenzo asserted Brazilian patent BRPI0405423B1 — covering a process and machinery for applying digital images to orthodontic braces — against Tecnoblu before the Court of Justice of São Paulo. The court rejected the appellate declarations in a May 2025 ruling, closing the case without further merits review.
São Paulo court rejects appeal in niche orthodontic patent dispute
Ricardo Augusto de Lorenzo, the individual patent holder of BRPI0405423B1, brought proceedings against Tecnoblu Indústria Comércio Importação and Exportação Ltda before the Court of Justice of São Paulo. The patent in dispute covers a specialised process for applying digital images to orthodontic braces, the associated machinery enabling that application, and the resulting brace products — a niche but commercially distinct segment of the Brazilian dental and orthodontic device market.
The appellate phase ended on 23 May 2025 when the court rejected the declaratory appeals (embargos de declaração), a procedural motion under Brazilian civil procedure typically used to clarify ambiguities, omissions, or contradictions in a prior ruling. The rejection means the underlying decision stands as rendered, without the clarification or amendment sought by the filing party. The case is now recorded as closed.
Because the filing date is absent from the public record, the total litigation duration cannot be calculated. The rejection of embargos de declaração is a common procedural endpoint in Brazilian appellate practice and does not necessarily signal a decision on the substantive patent merits. What drove the original lower-court outcome, and which party prevailed on the patent claims themselves, remains unclear from the available public record.

Appeal rejected: what the São Paulo ruling means for both parties
Embargos de declaração rejected — what this means
In Brazilian civil procedure, embargos de declaração (declaratory appeals) are a narrow procedural tool used to ask a court to correct omissions, contradictions, or obscurities in a ruling — not to relitigate the merits. Rejection means the court found no such defect. The prior decision stands unaltered, and this stage closes without any new substantive adjudication of the patent claims.
Procedural dismissalLorenzo: prior ruling preserved, but merits remain opaque
If de Lorenzo was the party filing the declaratory appeal, rejection means he failed to obtain clarification or amendment of an adverse or ambiguous ruling. If Tecnoblu filed the appeal, the rejection is neutral or marginally favourable to de Lorenzo. The public record does not identify the filing party, so the precise impact on the patent holder’s enforcement position cannot be confirmed from available data.
Outcome depends on appellant identityTecnoblu: underlying decision unchanged at this stage
Tecnoblu faces the prior ruling on its original terms. Rejection of the declaratory appeal forecloses that narrow avenue for amendment but does not exhaust all further appellate routes under Brazilian procedural law. Depending on the underlying merits decision, Tecnoblu may still have recourse to higher courts, including the Superior Tribunal de Justiça, if applicable legal grounds exist.
Further appeals possibleOrthodontic digital-image IP: enforcement risk persists
BRPI0405423B1 covers a process, machinery, and resulting product — a broad three-pronged protection that, if upheld on the merits, could restrict competitors across multiple points of the production chain. Brazilian orthodontic device manufacturers and importers operating in the decorative or digital-image brace segment should monitor the underlying patent status and any further appellate proceedings.

Official order — verbatim text
The court’s ruling — ‘I REJECT the appeals declarations’ — is a standard Brazilian appellate formulation disposing of embargos de declaração on procedural grounds. It confirms that the panel found no omission, contradiction, or obscurity requiring correction in the prior decision. Critically, this language does not constitute a ruling on patent validity or infringement. The substantive outcome of the underlying patent dispute therefore remains governed by whatever decision preceded this appellate stage, details of which are not fully disclosed in the available public record.
BRPI0405423B1 — digital image application process for orthodontic braces
BRPI0405423B1 is a Brazilian patent granted to Ricardo Augusto de Lorenzo covering three interconnected elements: a process for applying digital images to orthodontic braces, the machinery purpose-built for that application, and the braces produced by that process. The BRPI prefix indicates a Brazilian patent application that completed the national phase. The patent sits at the intersection of digital printing technology and dental device manufacturing — a niche that emerged as decorative and personalised orthodontic products gained commercial traction in Brazil.
The combination of process, apparatus, and product claims in a single patent creates a wide enforcement perimeter. A competitor seeking to design around faces the challenge of avoiding not only the production method but also the specific machinery and the resulting product characteristics. For the Brazilian orthodontic market — where customised and branded braces represent a distinct commercial segment — this patent’s scope makes it a material IP asset. Any entity manufacturing, importing, or distributing comparable digital-image braces in Brazil should treat BRPI0405423B1 as a live enforcement risk until its validity is conclusively resolved or its term expires.
Should you run an FTO against BRPI0405423B1?
If your organisation manufactures, imports, distributes, or develops machinery for digital-image orthodontic braces in Brazil, BRPI0405423B1 is directly relevant to your freedom-to-operate position. The patent’s three-pronged scope — process, machinery, and product — means that even partial overlap with your product line or production method may create exposure. This case demonstrates that the patent holder is actively litigating, making a pre-commercialisation FTO analysis essential rather than precautionary.

What this case signals for orthodontic device IP in Brazil
A procedural endpoint in São Paulo leaves the substantive patent position unresolved — significant for any player in the Brazilian decorative braces market.
Procedural closure ≠ merits resolution on BRPI0405423B1
The rejection of embargos de declaração closes this appellate stage without ruling on whether the patent is valid or infringed. Competitors and licensees should not treat this outcome as a clearance signal. The underlying patent grant remains in force unless separately challenged or invalidated.
Three-layer patent protection raises FTO complexity
BRPI0405423B1 claims a process, the machinery used in that process, and the resulting braces — a structural combination that creates overlapping enforcement vectors. Any Brazilian manufacturer, importer, or distributor touching digital-image orthodontic products should conduct a dedicated FTO analysis against this patent before commercialisation.
Lorenzo v Tecnoblu — key questions answered
The Court of Justice of São Paulo rejected the declaratory appeals (embargos de declaração) filed in this case on 23 May 2025, closing the appellate stage. The dispute concerns Brazilian patent BRPI0405423B1, which covers a process and machinery for applying digital images to orthodontic braces. No merits ruling on patent validity or infringement was issued at this stage.
BRPI0405423B1 is a Brazilian patent held by individual inventor Ricardo Augusto de Lorenzo. It covers a process for applying digital images to orthodontic braces, the machinery used in that process, and the resulting brace products. The BRPI prefix identifies it as a Brazilian national-phase patent application that progressed to grant.
Embargos de declaração are a procedural motion under Brazilian civil procedure (CPC Art. 1022) used to ask a court to correct omissions, contradictions, obscurities, or errors in a prior ruling. They are not an appeal on the merits. Rejection — as issued here — means the court found no such defect requiring correction. The prior decision stands unaltered.
No. The rejection of embargos de declaração is a procedural outcome and does not constitute a ruling on the validity or enforceability of BRPI0405423B1. The patent remains in force as granted by INPI unless separately challenged through an administrative nullity action at INPI or a judicial invalidity proceeding before the Brazilian federal courts.
Tecnoblu may have further appellate options under Brazilian law depending on the nature of the underlying decision, including a recurso especial to the Superior Tribunal de Justiça if federal law was misapplied. Separately, Tecnoblu could pursue an administrative nullity petition against BRPI0405423B1 at INPI or file a judicial invalidity counterclaim. The specific strategic path depends on the merits of the underlying ruling, which are not fully disclosed in the public docket.
