Lorenzo v. Tecnoblu: Digital Image Braces Patent Appeal Partially Dismissed
Ricardo Augusto de Lorenzo brought an appeal against Tecnoblu Indústria Comércio Importação and Exportação Ltda before the Court of Justice of São Paulo, disputing rights under patent application BRPI0405423A covering a process for applying digital images in braces and related machinery. The appellate court heard the appeal in part and dismissed the remainder, leaving key aspects of the lower decision intact.
Partial appellate dismissal in Brazilian digital-image braces patent dispute
Ricardo Augusto de Lorenzo initiated appellate proceedings against Tecnoblu Indústria Comércio Importação and Exportação Ltda at the Court of Justice of São Paulo under case number 2058180-04.2025.8.26.0000. The dispute centres on patent application BRPI0405423A, which covers a process for applying digital images in braces, the machinery required for such application, and the resulting braces product — a niche but commercially distinct technology within the orthodontic and dental accessories sector.
The court’s disposition, dated 9 April 2025, was nuanced: the appeal was heard in part and, on the grounds that were entertained, dismissed. This outcome suggests the appellate panel found at least some grounds admissible for consideration, yet ultimately rejected them on the merits or procedural basis. The portion of the appeal that was not heard — described as the ‘unknown part’ in the ruling — was declined without substantive review, leaving those aspects of the lower-court decision undisturbed.
The absence of a filing date in the public record makes it impossible to determine how long proceedings ran before the April 2025 closure. The partial hearing structure is consistent with Brazilian civil appellate practice, where courts may bifurcate admissibility and merit review across distinct grounds. What drove the dismissal of the known portion — whether substantive patent claim analysis, procedural defects, or evidentiary insufficiency — is not disclosed in the available record, and any further challenge would require Lorenzo to seek special or extraordinary appeal routes under Brazilian procedural law.

Appeal heard in part, dismissed in part: what this ruling means for both parties
Partial hearing and partial dismissal explained
A ruling that ‘hears in part’ and then ‘dismisses’ that heard portion indicates the court found certain grounds of appeal admissible but rejected them on the merits or substantive law. Grounds not heard were declined at the admissibility threshold. Under Brazilian civil procedure, this bifurcated outcome is a recognised appellate form — it is not a settlement or procedural abandonment, but a judicial determination against the appellant on the grounds reviewed.
Partial merits dismissalLorenzo’s appeal fails on all reviewed and unreviewed grounds
For Lorenzo, the partial dismissal is a substantive setback. The grounds the court was willing to examine were rejected, and the remaining grounds did not clear admissibility. The lower-court decision therefore stands in its entirety. Any further challenge would require pursuing special appeal (recurso especial) to the Superior Court of Justice or extraordinary appeal (recurso extraordinário) to the Supreme Court, both subject to strict admissibility filters under Brazilian law.
Appeal unsuccessfulTecnoblu: lower-court position confirmed, dispute risk reduced
Tecnoblu benefits from the appellate court’s refusal to disturb the lower-court outcome. With the appeal dismissed in part on the known grounds and declined on the remainder, Tecnoblu’s operational position in relation to the disputed process, machinery, and braces product is strengthened — at least at this court level. Residual risk of further appeal via special or extraordinary routes remains theoretically possible but faces high admissibility hurdles.
Respondent position upheldIP enforcement risk for digital-image orthodontic technology in Brazil
This outcome suggests that asserting process and machinery patents in the Brazilian orthodontic accessories sector via the appellate route faces meaningful procedural and substantive barriers. For companies operating in digital-image braces manufacturing or importation in Brazil, this case is consistent with a pattern where individual inventor appeals over niche manufacturing processes face close scrutiny on both admissibility and merits at the Court of Justice of São Paulo.

Official order — verbatim text
The court’s formulation — ‘I HEAR IN PART the appeal and, in the known part, I DISMISS it’ — is a precise Brazilian appellate construction. ‘Hearing in part’ signals that at least some grounds passed the admissibility filter and received substantive review; ‘dismissing’ those grounds means the court found them unpersuasive on the merits or law. Grounds not ‘heard’ were declined without substantive analysis. The net effect is a complete failure of the appeal: no part of the lower-court ruling was disturbed in Lorenzo’s favour.
BRPI0405423A — Digital image application process for orthodontic braces
BRPI0405423A is a Brazilian patent application covering a process for the application of digital images in braces, the machinery designed to execute that process, and the resulting braces product. The application number prefix ‘BRPI’ indicates a national phase Brazilian application. The ’04’ series suggests a filing year of 2004, placing this invention in an early period of digital printing and customisation technology in orthodontic accessories — a technically specialised intersection of imaging and dental device manufacturing.
The bundled scope of this patent — covering process, machinery, and product — gives the holder potential reach across the manufacturing supply chain: from digital image processing software and hardware to the finished customised brace. For competitors in Brazil’s orthodontic accessories market, this creates layered FTO considerations. The fact that the patent remains in application status (BRPI prefix) rather than a granted BI number means prosecution history and grant status should be verified before any commercial FTO conclusion is drawn.
Should you run an FTO against BRPI0405423A?
Any company manufacturing, importing, commercialising, or developing machinery for digital image customisation of orthodontic braces in Brazil should treat BRPI0405423A as a live FTO concern. The application’s broad scope — covering the process, the machinery, and the product — means exposure could arise at multiple points in your supply chain or product development workflow. The appellate dismissal in this case does not confirm the patent’s validity or grant status; it resolves a procedural dispute, not claim scope.

What this case signals for Brazilian orthodontic and manufacturing IP
A partial appellate dismissal in a niche process patent dispute highlights the enforcement challenges individual inventors face in Brazilian courts.
Brazilian appellate courts bifurcate admissibility and merit review
The partial-hearing structure used by the Court of Justice of São Paulo reflects a disciplined procedural approach: not all grounds of appeal reach the merits stage. Patent holders asserting process patents in Brazil should ensure each ground of appeal independently clears admissibility thresholds, as failure on one ground does not rescue others.
Process and machinery patents in orthodontics face multi-ground enforcement hurdles
BRPI0405423A covers a process, related machinery, and a resulting product — a bundled claim structure common in manufacturing patents. Brazilian courts may assess each element differently on appeal, meaning a patentee’s strongest claims must be clearly distinguished and individually supported to survive appellate review.
Lorenzo v Tecnoblu — key questions answered
The Court of Justice of São Paulo admitted some grounds of appeal for substantive review (‘heard in part’) but rejected them on the merits or applicable law (‘dismissed’). Grounds not admitted were declined without substantive analysis. The net result is that the entire lower-court decision stands in Tecnoblu’s favour and Lorenzo’s appeal failed at every stage.
BRPI0405423A is a Brazilian patent application, likely filed in 2004, covering a process for applying digital images in orthodontic braces, the machinery used for that application, and the resulting braces product. The BRPI prefix denotes a national phase Brazilian application. Its grant status and current prosecution state should be independently verified in the INPI register before drawing FTO conclusions.
Following a Court of Justice of São Paulo appellate dismissal, the available routes are a special appeal (recurso especial) to the Superior Court of Justice (STJ) on federal law grounds, or an extraordinary appeal (recurso extraordinário) to the Supreme Court (STF) on constitutional grounds. Both face strict admissibility filters and are rarely granted in niche manufacturing process patent disputes involving individual inventors.
No. The appellate dismissal resolves a dispute between the parties at this court level; it does not constitute a ruling on the validity, scope, or grant status of BRPI0405423A. The patent application remains on the Brazilian INPI register. Companies in the digital braces manufacturing or customisation space should independently verify the application’s current status and claim scope for FTO purposes.
The case signals that process and machinery patent enforcement via individual inventor appeals faces meaningful procedural and substantive barriers in Brazilian appellate courts. However, the underlying patent application BRPI0405423A remains a potential IP risk for companies manufacturing, importing, or selling digital-image customised braces in Brazil. A freedom-to-operate analysis against this application is advisable for market participants.
