Hi Chris,
Heard about this horrible thing. I don’t know if it helps, but I found this via Dug’s friend Jose Antonio’s blog
It’s a decision about a dispute over the domain name www.dada.com. Jose Antonio’s brother, Juan Carlos, was sued by a sportswear company called dada and he won. I’m not sure I totally get it, but it seems that some of the relevant things are “legitimate interest”, whether there is a “confusing similarity” with the names, whether you have a “sufficient interest” in the name.
Anyway, maybe Juan-Carlos or his lawyers could help you.
Hope you get it all sorted. What a bloody annoying bore,
Billy
