DPR Telecomunicações v. CG3 Telecom: Appeal Granted, Case Remanded to Trial Court
DPR Telecomunicações Ltda brought an infringement action against CG3 Telecom Indústria and Comércio over Brazilian utility model BRMU1411604U2, covering support structures for anchoring, suspending, and distributing cables. The Court of Justice of São Paulo granted DPR’s appeal, dismissing a preliminary procedural bar and ordering the litigation to continue at the origin court.
São Paulo appellate court clears path for cable support patent infringement trial
DPR Telecomunicações Ltda filed an infringement action against CG3 Telecom Indústria and Comércio asserting Brazilian utility model patent BRMU1411604U2, which covers support structures designed for anchoring, suspending, and distributing cables — a component category central to fixed and mobile telecommunications network infrastructure. The case was assigned case number 2094717-96.2025.8.26.0000 in the Court of Justice of São Paulo.
Before the merits of the infringement claim could be heard, a question of ‘external prejudice’ — a procedural mechanism under Brazilian civil procedure that can stay or extinguish proceedings due to a pending related matter — was recognised at the origin court level. DPR challenged that recognition on appeal. On 11 November 2025, the São Paulo appellate court granted DPR’s appeal, dismissed the recognition of the external prejudice, and ordered the litigation to resume at the origin court.
The outcome is procedural rather than substantive: no finding on infringement or patent validity has been made. DPR’s success on appeal suggests the appellate panel found insufficient legal basis to pause or terminate the action at origin, which is consistent with a patent holder seeking to prevent delay tactics. The merits of the infringement claim — including any validity challenge by CG3 Telecom — remain entirely unresolved and are now to be adjudicated at first instance.

Appeal granted: what the São Paulo ruling means for both parties
What ‘appeal granted’ means in this procedural context
The Court of Justice of São Paulo reversed the origin court’s decision to recognise ‘external prejudice’ — a civil procedure doctrine that can suspend or terminate proceedings where a separate related case is pending. By dismissing that recognition, the appellate court removed a procedural shield that could have halted DPR’s infringement action. No merits ruling on infringement or validity was made; the court’s role here was purely to decide whether the lower court erred procedurally.
Procedural appeal — merits pendingDPR Telecomunicações wins the right to pursue its infringement claim
DPR’s success on appeal means its infringement action will proceed at the origin court on the merits. The patent — BRMU1411604U2 — remains in force and its enforceability has not been adjudicated. DPR is now positioned to present its full infringement case, including claim mapping against CG3 Telecom’s products. The appellate ruling suggests the court found no legitimate parallel proceeding that would justify delaying or extinguishing the action.
Infringement action continuesCG3 Telecom must now defend on the merits at first instance
With the procedural bar removed, CG3 Telecom Indústria and Comércio faces the infringement action at origin without the benefit of the external prejudice stay. The defendant will need to mount a full defence — potentially including invalidity arguments against BRMU1411604U2 or non-infringement contentions regarding its cable support products. The appellate loss closes one procedural avenue but does not foreclose substantive defences at trial.
Merits defence requiredUtility model enforcement in telecoms infrastructure: litigation risk elevated
This case is consistent with a broader trend of Brazilian utility model holders actively enforcing structural telecoms components IP against competitors in the domestic market. Manufacturers and traders of cable management and distribution hardware should treat BRMU1411604U2 as live litigation risk. The appeal outcome suggests São Paulo courts are receptive to clearing procedural hurdles for patent holders, which may embolden similar enforcement actions in the infrastructure accessories segment.

Official order — verbatim text
The verdict language — ‘the appeal is granted to dismiss the recognition of the external prejudice and determine the continuation of the litigation at the Origin’ — is a procedural disposition, not a merits ruling. The appellate court found that the origin court incorrectly applied the external prejudice doctrine, which under Brazilian civil procedure requires a direct and necessary dependency between two pending proceedings. By dismissing that recognition, the panel effectively cleared the path for the infringement action to be litigated on its merits. Neither party has received a finding on patent validity or infringement at this stage.
BRMU1411604U2 — cable anchoring, suspension and distribution support structures
BRMU1411604U2 is a Brazilian utility model — designated by the ‘MU’ prefix in the INPI numbering system — covering support hardware for anchoring, suspending, and distributing cables. Utility models in Brazil protect three-dimensional objects of practical use and require only that the object presents a new form or arrangement with functional improvement, a lower threshold than invention patents. The ‘U2’ suffix indicates the patent has been granted and published. This class of hardware is fundamental to both fixed-line and wireless telecommunications network deployments, where cable management structures are required at scale.
Cable support and distribution hardware represents a high-volume, commoditised product category in telecoms infrastructure, making it a frequent target for utility model enforcement by domestic manufacturers seeking to exclude lower-cost competitors. The fact that DPR Telecomunicações has pursued CG3 Telecom — an industry and commerce operator — to the appellate level in São Paulo suggests commercial stakes beyond a single product line. Competitors sourcing or manufacturing structurally similar cable anchoring products in Brazil should regard BRMU1411604U2 as an active enforcement risk until the merits ruling at origin is published.
Should your product team run an FTO against BRMU1411604U2?
Any company designing, importing, manufacturing, or distributing cable anchoring, suspension, or distribution support hardware in Brazil should treat BRMU1411604U2 as a live freedom-to-operate concern. The ongoing São Paulo infringement action demonstrates that the patent holder is actively enforcing rights. Even if your product differs in materials or aesthetics, Brazilian utility model scope can extend to functionally equivalent structural arrangements — making a formal FTO assessment advisable before market entry or expansion.

What this case signals for the Brazilian telecoms infrastructure IP landscape
A procedural win in São Paulo sets the stage for a substantive infringement fight over cable support hardware — with broader implications for utility model enforcement in Brazil.
Brazilian utility models can support aggressive enforcement postures
BRMU1411604U2’s role in this case illustrates that Brazilian utility models — typically granted with less examination rigour than invention patents — can nonetheless underpin costly appellate-level litigation. Companies manufacturing cable support or distribution hardware in Brazil should audit their product lines against granted utility models in the infrastructure accessories space.
Procedural defences in Brazilian IP actions carry real appellate risk
CG3 Telecom’s external prejudice strategy was overturned on appeal. This outcome suggests that São Paulo’s Court of Justice applies a high threshold before accepting that a parallel proceeding justifies halting an infringement action. Defendants relying on procedural stays as a primary defence tactic should treat this ruling as a cautionary signal.
LTDA v CG3 — key questions answered
The court granted DPR Telecomunicações’ appeal, dismissing the recognition of external prejudice that had been applied at the origin court level and ordering the infringement action to continue at first instance. No ruling on patent validity or infringement was made.
BRMU1411604U2 is a granted Brazilian utility model patent held by DPR Telecomunicações Ltda. It covers support structures for anchoring, suspending, and distributing cables — hardware used in telecommunications network infrastructure. The ‘MU’ designation indicates a utility model under Brazil’s INPI classification system.
External prejudice (prejudicialidade externa) under Brazilian civil procedure allows a court to suspend proceedings when the outcome of a separate action is necessary to resolve the current case. At the origin court, this doctrine was applied to pause or bar DPR’s infringement action. The São Paulo appellate court found insufficient grounds for that application and dismissed the recognition.
Following the appellate ruling, the infringement action returns to the origin court in São Paulo for a full merits hearing. The court will consider whether CG3 Telecom’s cable support products infringe BRMU1411604U2. CG3 Telecom may raise invalidity defences or non-infringement arguments. The timeline for a first-instance judgment will depend on the origin court’s docket.
No. The appellate decision was purely procedural and does not address the validity or enforceability of BRMU1411604U2. The utility model remains in force. Any validity challenge would need to be pursued through a nullity action at INPI or as a counterclaim in the origin court proceedings.
