Laserflex v. Cilingraf: Flexographic Patent Appeal Dismissed as Prejudiced
Laserflex Industrial Ltda brought a patent action against Cilingraf Cilindros para Impressões Ltda before the Court of Justice of São Paulo, asserting utility model BRMU1905931U2 covering a hybrid ring edge protection device for flexographic cliché holders. The appeal was dismissed as prejudiced, ending the dispute without a ruling on the merits.
São Paulo court dismisses flexographic patent appeal as prejudiced
Laserflex Industrial Ltda, a Brazilian industrial manufacturer and holder of utility model BRMU1905931U2, initiated proceedings against Cilingraf Cilindros para Impressões Ltda, a company operating in the cylinder and printing supplies sector. The patent in suit concerns a hybrid ring edge protection and registration system for shirt port cliché holders used in flexographic printing — a precision component relevant to the packaging and label printing industries. The case was filed before the Court of Justice of São Paulo under case number 2090770-34.2025.8.26.0000.
The appeal was dismissed by the São Paulo court on 16 June 2025, with the tribunal characterising it as ‘prejudiced’ — a procedural finding under Brazilian civil procedure that typically means the appeal had already lost its object, purpose, or admissibility by the time it came before the court, rendering a substantive ruling unnecessary or impossible. The result is that the appellate court issued no decision on the validity of the patent or on any alleged infringement. The public record does not disclose a costs order.
Because the appeal was found to be prejudiced rather than decided on the merits, the underlying factual and legal questions — including whether BRMU1905931U2 was infringed and whether the utility model is valid — remain formally unresolved at the appellate level. The precise reason the appeal lost its object is not specified in the publicly available record. This outcome is consistent with scenarios such as a prior settlement between the parties, withdrawal of the appeal, or a supervening event rendering the appeal moot before the court could rule.

Appeal dismissed as prejudiced: what the ruling means for both parties
What ‘prejudiced appeal’ means in Brazilian procedure
Under Brazilian civil procedure, an appeal is declared ‘prejudiced’ (prejudicado) when it has lost its object before the court can rule — for example, because the underlying action was settled, the appeal was withdrawn, or a supervening event rendered the dispute moot. Crucially, this is a procedural termination, not a merits ruling. The court does not decide who was right; it simply closes the appellate file.
No merits adjudicationLaserflex achieves closure without an adverse appellate ruling
For Laserflex Industrial, the dismissal of the appeal as prejudiced means no appellate court has invalidated or narrowed utility model BRMU1905931U2. The patent remains formally intact and enforceable to the extent the lower-court position was favourable. However, because no merits ruling was issued, Laserflex does not gain a precedent affirming infringement or validity — limiting the deterrent value of this outcome against future challengers.
Patent technically intactCilingraf exits without a merits finding — risk remains open
Cilingraf Cilindros obtains dismissal of the appeal without a court finding of infringement against it at the appellate level. Depending on the lower-court record — which is not fully disclosed in the public docket — residual exposure under the utility model may remain. The absence of a merits ruling means Cilingraf cannot rely on this outcome as a definitive finding of non-infringement or invalidity in future disputes involving the same patent.
No infringement ruling issuedUnresolved IP leaves flexographic sector in continued uncertainty
Companies manufacturing or supplying cliché holder components and edge protection systems for flexographic printing should note that BRMU1905931U2 has not been adjudicated on the merits. The patent’s enforceability has not been tested by a Brazilian appellate court, which suggests that competitors and product designers in the flexographic printing supply chain should treat this utility model as potentially active and conduct freedom-to-operate analysis before commercialising similar designs.

Official order — verbatim text
The tribunal’s formulation — ‘the appeal is PREJUDICED’ — is a standard Brazilian procedural termination indicating that the appeal had lost its legal object before the court could examine the merits. This finding carries no implication of fault or substantive outcome for either party. It does not constitute an affirmance of any lower-court ruling on validity or infringement of BRMU1905931U2, nor does it create any binding precedent on the technical scope of the patent. Both parties’ substantive positions on the patent remain formally unadjudicated at the appellate level.
BRMU1905931U2 — Hybrid Ring Edge Protection for Flexographic Cliché Holders
BRMU1905931U2 is a Brazilian utility model — a form of industrial property protection available under Brazilian IP law (Law No. 9,279/1996) for inventions of practical utility with a lower inventive step requirement than a full patent. The subject matter concerns a hybrid ring device providing edge protection and registration for cliché holders used in flexographic printing presses. Flexographic printing is a rotary relief printing process widely used in the packaging, label, and flexible materials industries; cliché holders are the precision components that mount printing plates onto the printing cylinder.
Utility model BRMU1905931U2 sits at the intersection of precision mechanical hardware and the flexographic printing supply chain — a sector with significant commercial volume in Brazil, where domestic packaging manufacturers rely on locally sourced press components. Because the patent covers a specific ring geometry and edge-protection mechanism, it is commercially relevant to any manufacturer supplying cliché mounting systems, sleeve protectors, or registration accessories compatible with flexographic shirt port cylinders. The unresolved litigation suggests Laserflex considers the design space closely competitive, raising freedom-to-operate considerations for rivals.
Should you run an FTO against BRMU1905931U2?
Any manufacturer, importer, or distributor of cliché holder components, sleeve edge protectors, or registration ring systems for flexographic printing presses operating in or supplying the Brazilian market should treat BRMU1905931U2 as a live IP risk. The patent has not been invalidated or narrowed by any appellate ruling. Companies designing hybrid ring configurations for shirt port cylinders — whether for OEM supply, aftermarket distribution, or in-house press maintenance — should conduct a formal FTO analysis before launch or market entry.

What this case signals for the flexographic printing IP landscape in Brazil
Utility model disputes in Brazilian printing supply chains are rarely resolved on the merits — this case illustrates how procedural outcomes can leave commercial risk unresolved.
Prejudiced dismissals create no precedent — patent risk remains live
When a Brazilian appellate court dismisses a case as prejudiced, neither party gains a merits precedent. For companies in the flexographic printing supply chain, this means BRMU1905931U2 cannot be treated as dead or narrowed by this outcome. Competitors should continue to monitor the patent’s status and enforce history rather than assume the dispute resolved the underlying IP risk.
Brazilian utility models warrant proactive FTO before product launch
Utility models (modelos de utilidade) in Brazil have a lower inventive step threshold than invention patents, making them easier to obtain and more numerous in industrial hardware sectors like printing equipment. R&D teams designing cliché holder components, edge protection rings, or registration systems for flexographic presses should run FTO analysis against the BRMU utility model register before commercialisation.
LTDA v CILINGRAF — key questions answered
In Brazilian civil procedure, an appeal declared ‘prejudicado’ (prejudiced) has lost its legal object before the court reaches the merits — typically because the dispute was settled, the appeal was withdrawn, or a supervening event made a ruling unnecessary. In this case, the São Paulo Court of Justice dismissed the appeal on that basis on 16 June 2025, issuing no decision on patent validity or infringement of BRMU1905931U2.
Yes, the dismissal of the appeal as prejudiced does not invalidate or narrow BRMU1905931U2. No appellate court ruled on the patent’s validity or scope. The utility model remains formally in force unless and until it is separately challenged at INPI or invalidated by a Brazilian court in a future proceeding.
BRMU1905931U2 covers a hybrid ring edge protection and registration system for shirt port cliché holders used in flexographic printing presses. Flexographic printing is a rotary relief process used in packaging and label manufacturing; cliché holders mount printing plates onto press cylinders. The patent concerns the specific geometry and protective mechanism of the edge ring component.
The plaintiff is Laserflex Industrial Ltda, a Brazilian industrial manufacturer and holder of utility model BRMU1905931U2. The defendant is Cilingraf Cilindros para Impressões Ltda, a Brazilian company operating in the cylinder and printing supplies sector. No law firms or legal representatives are listed in the publicly available case record.
Under Brazilian IP law (Law No. 9,279/1996), a utility model (modelo de utilidade) protects practical improvements to objects of practical use with a lower inventive step threshold than a full invention patent. Utility models are easier and faster to obtain, but have a shorter maximum term (15 years from filing). For competitors, this lower threshold means utility models can cover incremental design variations, making freedom-to-operate analysis particularly important for adjacent product designs in the flexographic equipment market.
