A registered trademark confers a bundle of exclusive rights upon the registered owner, including the right to exclusive use of the mark in relation to the products or services for which it is registered. For example, without the registration, a plaintiff is unable to claim trademark infringement under the Lanham Act. Therefore, the ability to enforce in Federal Courts is paramount to the trademark registration. Also, a common-law (unregistered) trademark is not vetted or reviewed and there could be geographic or goods/services issues.
