I’m sometimes asked if you can do something about a domain that uses your name, your company or product name or something similar. The answer is usually no, but there are exceptions.
Here’s the basic rules – with a classic violation (source: Google Goes After YouTube Domain Typo Squatter):
the three primary criterion are “identical or confusingly similar to a trademark” (check), “owner has no rights or legitimate interests in respect of the domain name” (check), and “domain name has been registered and is being used in bad faith”
This by the way, is not handled in court, but through the procedures of ICANN, the international organization that controls domain name registrations.
