How does Brazil PCT national-phase entry work in 2026?
This guide focuses on entry of an existing international application into Brazil; it is not an outbound Brazilian PCT filing guide.
Direct answer: Brazil’s PCT national-phase entry involves the applicable 30-month deadline, Portuguese-language materials and INPI service 200. Since 16 September 2026, INPI’s new Patent Services Module supports filing with integrated GRU generation and payment; legacy systems remain available during the transition.
Direct answer: Brazilian national phase filing
Brazilian national phase and territorial protection
Brazilian PCT national-phase entry is an application procedure before Instituto Nacional da Propriedade Industrial (INPI), not an automatic conversion from a PCT publication into a Brazilian patent. INPI's official guidance states a 30-month period counted from the priority date, including the oldest priority when more than one is claimed. A national-phase application generally needs Portuguese application materials and the appropriate request, payment and representation documentation.
Inbound Brazil filing versus PCT international filing
The decision should start with the precise PCT dates, the Portuguese-language filing package, the operative INPI portal and whether Brazilian protection is justified by commercialization or manufacturing risk. INPI's public national-phase material and its September 2026 system announcement provide unusually important freshness evidence for this page.
Calculate the 30-month period from the correct earliest priority date and preserve the original priority and PCT records. INPI's national-phase guidance identifies a 30-month entry period and specifies documents and payment steps. A generic 31-month PCT chart from another jurisdiction cannot be substituted for Brazil's published national requirements.
Late-entry exceptions require source and counsel review
If a case is already outside the apparent entry window, determine whether any restoration or other remedy is legally available from current Brazilian rules and facts. Do not promise acceptance of a late filing. The deadline file should contain the priority records, international application number, deadline calculation, document completion status and a separate note of any procedural exception requiring local advice.
Portuguese translation scope
Portuguese national document inventory
INPI describes the Portuguese-language application package as including the specification, claims, drawings if applicable and abstract, adapted to the applicable requirements. The precise translation and document rules should be checked for the case and current electronic service. Patent translation is not merely administrative: technical claims should preserve the structure, function and limitations that were disclosed internationally.
Consistency between international and translated claims
A translation-quality matrix should compare key independent-claim phrases with source paragraphs and figures. Identify chemical names, biological sequences, numerical ranges, algorithmic stages or process parameters that could change meaning in Portuguese. Maintain a record of which PCT amendments are being used and whether the Brazilian entry package corresponds to the legally relevant international documents.
Service 200 and official fee route
INPI service 200 and GRU sequence
INPI identifies service code 200 for entry into the PCT national phase and provides an official fee table and GRU payment mechanism. The payable amount and any applicable reductions must be confirmed for the actual applicant and filing date; services connected with examination and later prosecution involve additional charges. A cost estimate should therefore separate national entry, translation, professional representation and later examination or maintenance expenses.
Fee receipt and claim/identifier records
Do not copy an old price from a consultancy article without checking the current official table. The filing team should document the relevant service code, generated GRU, proof of payment, application record and receipt. Some applicants may qualify for fee reductions under specified rules, but those conditions require individual verification.
INPI confirms that service 200 filing in the Patent Services Module now includes GRU creation and online payment. During the transition, previously generated PAG guides and legacy submission paths remain supported as specified by INPI: INPI announcement, 16 September 2026.
September 2026 filing system transition
New September 2026 module
INPI announced that the second version of its Patent Services Module became available on 16 September 2026 for domestic patent deposits and PCT national-phase entry under service 200, including integrated GRU payment. Its announcement also states that legacy payment and electronic petition channels remain available during the transition. This means an older page saying all entries must use only the previous electronic system would be outdated.
Legacy PAG and e-Peticionamento transition caveat
Before a real filing, confirm the currently operative module, user credentials, document-upload options and how an existing GRU can be used. Test whether the case data and document set fit the new interface. Retain a dated acknowledgement and any system-generated warnings. The operational procedure may continue evolving after initial launch.
Representation / authorization document checks
Authorization and representative documents
The Brazilian file should identify the rightful applicant, representation authority and any required power of attorney. INPI's national-phase guidance refers to a properly executed power of attorney as part of the documents expected. Where the applicant has changed during the international phase, compare WIPO bibliographic records with assignments and the Brazilian agent's requirements.
Do not assume blanket agent mandates
A missing or inconsistent signature can have consequences even when the underlying invention is clearly identified. Translation and authorization work should therefore begin ahead of the 30-month deadline, not on the final day. Keep the local representative's written confirmation of the application data and instructions as part of the filing audit trail.
Examination and claim strategy after entry
National entry versus subsequent examination
National-phase entry opens the route to examination in Brazil. The applicant must later address local examination requests and consider whether the claims as entered cover actual products, manufacturing processes or commercially valuable technical features. International written opinions and foreign office actions can inform risk evaluation but are not substitutes for INPI's examination standards and formal procedures.
Claims and national prosecution chronology
Preserve the description's fallback support for amendments. A claim narrowed elsewhere may be useful as a reference, yet the Portuguese disclosure and Brazilian record require independent analysis. Build a multi-year budget for formalities, examination, office responses and maintenance rather than treating the initial GRU as the total cost of Brazilian protection.
The final entry sheet should show earliest priority, 30-month date, PCT identifier, Portuguese translation package, service 200, GRU payment, representative authorization, applicant chain of title and confirmed portal. Record whether a later examination deadline or official communication has already been received. A proof-of-submission package is mandatory for operational confidence.
Transaction receipt and next-step record
The major failure modes are using the wrong deadline, filing an unreliable translation, assuming the old portal remains the only method, and failing to preserve payment/acknowledgement evidence. Brazil can be a strategically important market, but country-entry spending should still be linked to the expected product, licensing or competitive outcome.

Evidence and deadline verification checklist
The audit trail should connect each procedural decision to a dated primary-source record and named reviewer. These items are practical evidence requests, not a guarantee of filing acceptance, enforceability or grant.
Application identity: Application number, applicant and entitlement, inventor names and current correspondence authority
Chronology: Earliest valid priority, other claimed dates, notice or entry deadline and calculated basis
Technical material: Original claims and description, figures, amendments, prior art and any technical translation
Current office procedure: Official instructions, accepted portal, forms, applicable fees and proof of submission
Legal review: Applicable exceptions, country-specific practice, disclosure support, agent instructions and next deadline
