Lorenzo v. Tecnoblu: Appeal Dismissed in Digital Image Braces Patent Case
Ricardo Augusto de Lorenzo brought a patent infringement action against Tecnoblu Indústria Comércio Importação e Exportação Ltda before the Court of Justice of São Paulo, asserting Brazilian patent BRPI0405423B1, which covers a process for applying digital images in braces and related machinery. The appellate court dismissed the appeal, closing the case on 5 November 2023.
Digital image braces patent dispute ends at São Paulo appellate level
Ricardo Augusto de Lorenzo initiated an infringement action against Tecnoblu Indústria Comércio Importação e Exportação Ltda before the Court of Justice of São Paulo, asserting Brazilian patent BRPI0405423B1. The patent covers a process for the application of digital images in orthodontic braces, the machinery used for such application, and the resulting braces product. The case number is 2272442-43.2023.8.26.0000/50000.
The recorded basis of termination is 'Appeal Dismissed'. The court's order states: 'In view of the foregoing, I DISMISS the appeal, PREJUDICED the internal aggravation.' This indicates the appellate proceeding was terminated without a merits determination on the underlying infringement claims at this appellate stage. The specific grounds on which the appeal was dismissed are not disclosed in the available record.
The case closed on 5 November 2023. What drove the appellate dismissal — whether procedural, jurisdictional, or otherwise — is not disclosed in the available record. The status of any underlying first-instance proceedings and whether further challenge is possible also remain unclear from the public record.

BRPI0405423B1 — digital image application process for orthodontic braces
Any company manufacturing, importing, or selling orthodontic braces featuring digital image application in Brazil should assess freedom to operate against BRPI0405423B1. The patent's dual coverage of process and machinery means both production methods and equipment could fall within scope. This is particularly relevant for dental device importers, orthodontic labs, and digital customisation technology providers active in the Brazilian market.
Official order — verbatim text
The court's order dismissing the appeal and declaring the internal aggravation 'prejudiced' indicates a procedural termination at the appellate level before the Court of Justice of São Paulo. No merits determination on the underlying infringement claims under BRPI0405423B1 is recorded in the available decision text.
Appeal dismissed: what the ruling means for both parties
Appeal dismissed — no appellate merits ruling issued
A dismissed appeal means the Court of Justice of São Paulo terminated the appellate proceeding without adjudicating the underlying infringement merits at this level. The court also noted the internal aggravation motion was 'prejudiced' — rendered moot by the dismissal. The specific procedural or substantive basis for dismissal is not disclosed in the available record.
Procedural terminationLorenzo's appeal closed without appellate vindication
For Ricardo Augusto de Lorenzo, the dismissal of the appeal means no appellate court ruling was issued in his favour at this stage. Whether the first-instance decision remained in effect or what avenue, if any, remains open for the patent holder is not disclosed in the available record.
No appellate merits winTecnoblu avoids appellate infringement finding
For Tecnoblu, the dismissal of the appeal means no appellate infringement finding was entered against it at this level. However, the status of any first-instance proceedings and whether the defendant remains exposed to further action under BRPI0405423B1 is not determinable from the available record.
No appellate liabilityPatent's enforceability in this dispute left unresolved
The appellate dismissal leaves the commercial enforceability of BRPI0405423B1 — covering digital image application processes for orthodontic braces — unresolved at this level. Market participants in the Brazilian orthodontic braces and digital printing sector should note that the patent remains on the register and the underlying infringement question was not conclusively adjudicated on appeal.

R&D signals in digital orthodontic imaging and braces technology
Forward-looking patent and innovation intelligence derived from the BRPI0405423B1 dispute between Lorenzo and Tecnoblu in the digital braces customisation sector.
Lorenzo's filing activity in digital braces imaging
Ricardo Augusto de Lorenzo's assertion of BRPI0405423B1 suggests active individual inventor IP activity in the digital orthodontic space. Tracking Lorenzo's broader Brazilian and PCT filing history could reveal whether additional patents cover adjacent braces customisation processes or machinery — relevant intelligence for competitors and potential licensees.
Inventor portfolio watchFiling trends in digital image application for orthodontic devices
The assertion of a process-and-machinery patent covering digital image application to braces points to an emerging IP cluster in orthodontic personalisation technology. Mapping filing trends in this space — including digital printing, UV imaging, and surface decoration of dental appliances — can identify competitors building competing or complementary patent positions in Brazil and globally.
Orthodontic imaging IP trendsTecnoblu's patent position in braces manufacturing
Tecnoblu Indústria Comércio Importação e Exportação Ltda operates as a Brazilian manufacturer and trader of braces. Assessing whether Tecnoblu holds its own defensive patents in orthodontic manufacturing or digital decoration technology — or relies on freedom-to-operate — is relevant for understanding competitive dynamics and potential cross-licensing opportunities in this niche.
Defendant IP landscapeAdjacent innovation opportunities near BRPI0405423B1
The patent covers a specific digital image application process and machinery for braces. Adjacent white spaces may exist in: alternative digital decoration techniques (laser, inkjet, sublimation), next-generation clear aligners with digital markings, or digital traceability systems embedded in orthodontic devices. These areas may represent lower-density IP zones for R&D investment in Brazil.

What this case signals for the Brazilian orthodontic IP landscape
A dismissed appeal in a niche braces-technology patent dispute highlights enforcement complexity in Brazilian IP proceedings.
Brazilian patent enforcement via appellate route can end procedurally
This case illustrates that patent infringement appeals before the Court of Justice of São Paulo can be dismissed on grounds not disclosed in the public record, leaving the underlying dispute unresolved. IP holders asserting Brazilian patents should plan for procedural attrition at the appellate stage.
BRPI0405423B1 remains an active risk for digital braces manufacturers
Despite the appeal dismissal, Brazilian patent BRPI0405423B1 — covering digital image application in braces and related machinery — remains on the register. Companies operating in orthodontic braces manufacturing or digital customisation in Brazil should conduct an FTO assessment against this patent.
Lorenzo v Tecnoblu — key questions answered
The recorded basis of termination is 'Appeal Dismissed'. The Court of Justice of São Paulo dismissed the appeal on 5 November 2023. The court order states the internal aggravation was also 'prejudiced'. No appellate merits ruling on the underlying patent infringement claim is recorded in the available decision.
BRPI0405423B1 covers a process for the application of digital images in orthodontic braces, the machinery used for such application, and the braces produced through that process. It was asserted by individual inventor Ricardo Augusto de Lorenzo against Tecnoblu in an infringement action before the Court of Justice of São Paulo.
The specific grounds for dismissal are not disclosed in the available record. The court order states only that the appeal is dismissed and the internal aggravation motion is prejudiced. Whether the dismissal was procedural, jurisdictional, or on another basis cannot be determined from the public record.
No. The appeal dismissal does not render the patent unenforceable. BRPI0405423B1 remains on the Brazilian patent register. The dismissal ended the appellate proceeding without an appellate merits ruling, but the patent's enforceability and the status of any first-instance proceedings are not determinable from the available public record.
In Brazilian civil procedure, a motion being declared 'prejudiced' typically means it has been rendered moot — in this context, because the appeal itself was dismissed, the internal aggravation motion (a procedural challenge to the appellate panel's internal decision-making) had no remaining basis and was accordingly set aside without separate adjudication.
