TRADEMARK CLASS CONFLICT GUIDES
Trademark classes: where conflicts happen and which classes to clear
The USPTO groups goods and services into 45 classes. Confusion rarely stops at one class — related classes matter too. Each guide explains what a class covers, why marks collide in it, the related classes to clear, and how to monitor new filings.

Trademark class FAQ
- How many trademark classes are there?
- The Nice Classification the USPTO uses has 45 classes: Classes 1–34 cover goods and Classes 35–45 cover services. A single brand often files in several classes.
- Do I only need to worry about my own class?
- No. Likelihood of confusion is assessed across related goods and services, not just an exact class match. A mark cleared in one class can still be blocked or challenged based on closely related classes, which is why these guides list the related classes to clear.
- Does the USPTO monitor my class for new filings?
- No. The USPTO examines and publishes applications but does not watch for confusable new filings on your behalf. You can read the weekly Trademark Official Gazette yourself or set a watch term for same-day alerts.
