I have a name which I bought in good faith in 2004 to possibly develop into a music site. However I am being threatened by the lawyers of a well known US company that I should just hadn over the name because they have the Trademark and the community trade mark. However I registered the name checking the UK TM search and this was fineas they TM's after my registration. They name seek to claim ownership in retrospect. Any advice gratefully recieved.
