This lesson is a follow up to the European Union-Trademark Basics lesson. It presents additional information concerning two topics: "Unusual" marks and Exhaustion of trademark rights. (With regard to the latter, there is a comparison with U.S. law in the lesson.) At a minimum, users should be familiar with U.S. trademark law and should either review the Basics lesson or be generally familiar with EU trademark law. This lesson may be best used for review and additional learning.
