LAW 783-001 – Trademark Law and Practice
There is no hard line for what a famous mark is, but it has to be really famous. Usually around 70% recognition among the general population is required.
To determine whether a mark is famous, four factors are used:
- The extent of duration and geographic reach
- The volume and geographic extent of sales
- The extent of actual recognition
- If it was registered before the creation of the principal register
