Buried in the third-to-last paragraph of this otherwise inconsequential New York Sun story about Current TV (Al Gore’s user-driven cable network, discussed back here) is this little tidbit: “Current TV is facing a trademark lawsuit brought by Minnesota Public Radio, which uses the phrase ‘The Current’ to describe some of its programming. Mr. Gore’s venture has yet to file a formal response to the suit, which is in its preliminary stages in federal court in St. Paul.” Yowza, anyone heard anything more about this? Update via the comments: a pdf of the complaint.
