One of the most important aspects of trademark law is determining ownership of the federal registration through a corporation records search.  For example, what happens if a corporation has been administratively dissolved at the time they file for a trademark or go to renew an existing registration?  It is quite possible the trademark registration is invalid.  Searching corporations is also useful when investigating ownership interests in patents and copyrights.  Clicking on the state below will launch a new window with the search interface for the state’s division of corporations.
