A few years ago, Re/Max, the real estate brokerage company, sued a competitor in the real estate market. The conflict focused on the alleged similarity of M.L. Jones & Associates’ yard signs and Re/Max’s famous red, white, and blue logo. Re/Max has been using the logo in at least one format since 1974, and has several longstanding US trademark registrations. Assuming the marks are similar, this is an open-and-shut case for Re/Max, right? A U.S. District Court judge in North Carolina came to a different, possibly logical but certainly vexillogical, conclusion.
