How to register and protect your company's trademark

A trademark is often a company's most valuable asset — and one of the least protected. Registration ensures exclusivity and prevents third parties from trading on your reputation.

Why register

Without registration, using a trademark does not guarantee exclusivity. As a rule, whoever registers first holds the right to use it — which means another company could register your trademark before you and prevent you from using it.

How registration with the INPI works

  • Prior-art search to check availability;
  • Definition of the class according to the activity;
  • Filing of the application with the INPI;
  • Follow-up through to grant and, thereafter, periodic renewal.

Protection goes beyond registration

Registration is the foundation, but effective protection involves monitoring misuse by third parties, appropriate licensing agreements and, where necessary, measures to stop infringements.

Frequently asked questions

How long does a trademark registration last?

The grant is valid for ten years, renewable for equal and successive periods upon a renewal request.

Do I need to register the trademark in every class?

Not necessarily. Registration is made in the classes corresponding to the activity. Broader protection strategies may cover additional classes depending on the business's interests.
