One way to do something about it is to trademark the business name, that may force the new company to chose a different name for its business.
I'm more interested (if anyone knows) whether I should be sending these guys an email pointing out that I already operate a website in the same space with the same name and whether prior use (without a trademark) counts for anything. They haven't launched yet, and I don't want to find in two years time that I cannot use my domain.
