Intellectual Property

Yes. In Mexico trademark rights arise from registration, not from use. Whoever registers first can stop you from using the name you built, and recovering it later costs far more than timely registration would have.

Names, logos, combinations of both and, in certain cases, elements such as sounds, trade dress or even scents. Generic terms, purely descriptive terms and marks confusingly similar to an existing registration in the same class cannot be registered.

Because it reveals whether identical or similar marks already exist in your class. Filing without searching risks losing both time and the official fee, and sometimes reveals that the name you already use infringes someone else's right. It is the cheapest step in the process and the one that prevents the most trouble.

No. Registration is territorial: it protects in the country where it is granted. If you plan to export or operate abroad, it is worth deciding early which countries to file in, since there are mechanisms that reduce the cost when planned ahead.
