BR102012027941B1 — Cap with cutting depressant for flexible vial packages


Any manufacturer or importer of caps, closures, or dispensing mechanisms for flexible vial packages operating in Brazil should treat BR102012027941B1 as a live risk requiring formal FTO assessment. The patent has been enforced through litigation, and the appeal has been dismissed — confirming that the patent remains in force and that the Brazilian court system has upheld an infringement determination under it. Product teams developing new flexible vial cap designs or adapting existing closure systems for the Brazilian market should specifically assess whether cutting depressant mechanisms fall within the patent's claim scope.
Official order — verbatim text
The appellate order maintains the prior aggravated decision and dismisses the appeal in its entirety. The court's pre-questioning notation — standard in Brazilian civil procedure — preserves all constitutional and statutory arguments for potential further review before higher courts. The order does not disclose the substantive findings of the first-instance decision, leaving the specific relief or liability determination not visible in this record.
Appeal dismissed: what the ruling means for both parties
Appeal dismissed — no merits reversal at appellate level
A dismissal of appeal at this level means the Court of Justice of São Paulo declined to reverse or modify the prior decision. The lower ruling is maintained as-is. The court's notation that all constitutional and legal treaties were considered pre-questioned preserves the record for any potential further review, but no reversal was ordered at this stage.
Lower decision upheldPlastek do Brasil retains the benefit of the prior ruling
With the appeal dismissed, Plastek do Brasil's position under the first-instance decision stands. The enforceability of BR102012027941B1 and any relief granted at first instance are preserved. The specific terms of that underlying ruling — including whether injunctive relief or damages were awarded — are not disclosed in the available record.
Prior decision maintainedRevpack's appeal fails; first-instance outcome binding
Revpack's attempt to challenge the prior ruling through appeal was unsuccessful. The decision against Revpack, to the extent established at first instance, remains in force. Revpack's options for further recourse would depend on Brazilian procedural rules governing higher review, but no further proceedings are recorded in the available docket.
Appeal unsuccessfulFlexible vial cap IP: enforcement signal for plastic packaging sector
This outcome suggests that Plastek do Brasil's patent position over cutting-depressant cap technology for flexible vials has withstood appellate scrutiny in Brazil. Competing manufacturers of pharmaceutical and liquid packaging closures operating in Brazil should assess their product designs against BR102012027941B1, particularly where flexible vial cap mechanisms are involved.

Ltda. v Revpack — key questions answered
The recorded basis of termination is 'Appeal Dismissed'. The docket order states the court maintained the prior aggravated decision and dismissed the appeal. The case closed on 24 May 2023. The specific findings of the first-instance decision are not disclosed in the available record.
The patent in dispute is BR102012027941B1, a Brazilian granted patent covering a cap with a cutting depressant mechanism for flexible vial packages and flexible vials capped with cutting of drop. The 'B1' designation confirms the patent was granted following full examination by the INPI.
The dismissal of Revpack's appeal means the prior decision against Revpack is maintained. Revpack's challenge at the appellate level was unsuccessful. Any obligations or findings established at first instance remain binding. Whether Revpack has pursued or can pursue further review before a higher Brazilian court is not recorded in the available docket.
In Brazilian civil procedure, pre-questioning of constitutional and legal treaties is a standard step that preserves all statutory and constitutional arguments for potential escalation to higher courts, including the Superior Court of Justice (STJ) or the Supreme Court (STF). The notation does not itself indicate that further review was filed or granted — it is a procedural preservation mechanism.
