http://www.pwinsider.com/article/70198/ecw-trademarked-for-wrestlingand-not-by-wwe.htmlAn LLC based in New York named 'Mocker' registered to trademark "ECW" for wrestling use back in March. WWE apparently let the trademark slip.
It was just 'assigned to an examiner' a few days ago, so I guess they just started working on it now.
That's pretty damn stupid on WWE's part. They'll probably fight to get it back though.
