I would have asked this in the Startups SE site but it's closed now and the topic of this site seems the best for for my question.
I'm working on a startup, and I've chosen a name. The .com is already registered by a domain parker. I understand that it's illegal to register a domain using someone else's trademark name and that the domain can be retrieved via legal action, but is it possible to force a domain parker to hand over a domain when he or she registered the domain before I register my company name?
