“Nattanzinho” and the Trademark Dispute at INPI: How to Protect Your Stage Name in Brazil

Do you use a stage name? Protect it before problems arise

If you’re a musician, artist, or public figure, your name is your brand. And protecting it is essential. Recently in Brazil, singers Nattan and Natanzinho Lima became involved in a dispute over the use of the name “Nattanzinho.” The issue is being evaluated by INPI, Brazil’s National Institute of Industrial Property — the government agency responsible for trademarks.

The matter is currently being handled administratively, not in court. Still, the outcome could directly affect the public use of the name and set an example for other artists.

What’s happening?

• In 2024, Nattan officially filed for the trademark “Nattanzinho.”

• Natanzinho Lima filed an opposition, claiming prior use since 2017.

• INPI is now reviewing the documents and evidence submitted by both parties.

Such trademark disputes are not uncommon and can arise even when no bad faith is involved. The core question is: Who has legal priority to use the name?

What are the risks of not registering your name?

Without a trademark registration, artists and creators may face:

• Restrictions on using their stage name publicly;

• Removal of their content from platforms like Spotify, YouTube, or Instagram;

• Suspension of promotional or commercial contracts;

• Loss of brand recognition built over time.

How to protect your stage name

You can avoid these issues by taking preventive measures:

1. Register your stage name with INPI as early as possible;

2. Keep detailed records showing consistent use of the name (social media posts, concerts, releases);

3. Choose unique names that don’t conflict with existing artists;

4. In case of dispute, monitor the administrative process and be ready to provide solid evidence.

Conclusion

Your name is part of your identity and your brand. Registering it gives you peace of mind and control over how it’s used. If you’re unsure about your rights or the registration process, consult a trusted attorney with experience in trademark and entertainment law.
