On 28 November 2025, the Brazilian Patent and Trademark Office (INPI) released a new
update to its Manual de Marcas, simultaneously implementing
Portaria INPI/PR nº 15/2025 (Acquired Distinctiveness) and
Portaria INPI/PR nº 36/2025 (Restricted Opposition – service code 3022).
For the first time, Brazil now has:
Key takeaway: Brazil becomes a more predictable, data-driven and globally aligned trademark jurisdiction,
especially for borderline descriptive marks and high-volume opposition strategies supported by AI tools.
The reform is anchored in the existing Brazilian Industrial Property Law and is operationalized through updated
administrative instruments:
These instruments are integrated into INPI’s 2025 Action Plan and linked to strategic projects
P1.15 – Oposição 2.0 para Marcas and
P1.08 – Distintividade Adquirida e Marcas Não Tradicionais.
Before 2025, Brazil acknowledged the concept that a descriptive or weak sign could become distinctive through use,
but there was no clear, standardized procedural route. The new rules change that, offering a
structured pathway with defined evidentiary expectations.
Under Portaria 15/2025 and the updated Manual, Acquired Distinctiveness (distintividade adquirida) is:
“The situation where a sign which, originally, would not have been registrable for lack of inherent distinctiveness,
has become capable of distinguishing the applicant’s goods or services as a result of the use made of it in commerce.”
AD is not intended to “rescue” every descriptive term, but to recognize exceptional cases where the market
effectively associates a sign with a single commercial origin.
To request the analysis of Acquired Distinctiveness, applicants must follow specific procedures and attach robust evidence,
which may include:
The overall burden is substantial: Brazil positions AD as a high standard, closer to EU expectations than to a purely
formal declaration of long-term use.
Comparing Brazil’s new rules with other major offices helps foreign practitioners calibrate their expectations.
In practice, all the main systems treat Acquired Distinctiveness as an exception, but with different levels of burden:
Portaria INPI/PR nº 36/2025 introduces service code 3022 for
“Oposição com restrição de alegações, limitadas à proteção de marca registrada de terceiro (Art. 124, XIX, da LPI)”.
This creates a streamlined opposition format focused exclusively on conflicts with prior registered marks.
In comparative terms:
For portfolios with dozens or hundreds of marks in Brazil, 3022 can be used as a first-line enforcement mechanism,
especially when combined with AI-based watch and conflict detection systems.
Although the procedure is now clarified, Acquired Distinctiveness remains an exceptional route.
The conceptual curve below illustrates, qualitatively, how the likelihood of success grows as the evidence package
becomes stronger and more comprehensive.
In pharma, where nonproprietary names (INNs) and highly descriptive terms are common, AD may offer an additional
layer of protection for brands that have built significant recognition in Brazil. At the same time, Restricted
Opposition becomes a useful tool to react quickly against confusing later marks filed for overlapping therapeutic
classes.
Technology and AI companies often adopt semi-descriptive names and slogans. The new AD framework allows, in principle,
for strong evidence-based claims when those signs have become recognized by Brazilian users. Automated conflict
detection can feed directly into 3022 oppositions, creating a data-driven enforcement loop.
For retail and fast-moving consumer goods, slogans and trade dress elements may benefit from AD arguments when
the brand has achieved broad penetration in Brazil. However, brand owners should still prioritize inherently distinctive
marks and rely on AD only as a complementary strategy.
Em 28 de novembro de 2025, o INPI disponibilizou uma nova atualização do Manual de Marcas, acompanhada das Portarias
INPI/PR nº 15/2025 (Distintividade Adquirida) e nº 36/2025 (Oposição com restrição de alegações – código 3022).
O conjunto normativo consolida:
自 2025 年 11 月 28 日起,巴西国家工业产权局(INPI)通过更新《商标审查手册》并发布
第 15/2025 号公告(显著性取得)和 第 36/2025 号公告
(限制性异议,3022 服务代码),对商标实务进行了重要改革。
