Legal Question in Intellectual Property in New Jersey

US trademark registrations are divided into classes. The registration of a trademark within a class gives the owner only the rights of a registant in that class of goods or services. However, there is the possibility that the trademark owner has also aquired rights under State or common law in areas outside of the registered class. If so, those rights can be licensed. This area of the law is complex and, before you make any important decisions, you should consult with an attorney.
