Different types of Trademarks:
Federal trademarks are filed with the USPTO and provide protection in all 50 states. To file for a federal trademark application the owner must be currently using or intending to use the mark in commerce across state lines.
State trademarks are typically filed with the state’s Secretary of State Office and provide for trademark protection within the state. Common Law trademark rights are obtained through use of the mark and are not governed by federal or state statute based on filing a trademark application, instead common law trademark rights developed under court created rights governed by state law.
Since common law trademark rights are obtained through use their scope is limited to the geographic area in which the mark is actually used or in areas it may naturally expand.
