Not really – you may recieve a cease and desist order, and if their really serious than it will be taken to the WIPO for arbitration. NOTE: the complainant is required to pay all fees to the panel unless the respondent(you) requests a three person panel.
The factors that the WIPO panel uses:
i) whether the domain name is identical or confusingly similar to a trademark or service mark in which the complainant has rights;
ii) whether the respondent has any rights or legitimate interests in the domain name (for example, the legitimate offering of goods and services under the same name);
iii) whether the domain name was registered and is being used in bad faith.
If you ever respond to a WIPO panel, keep your response civil and professional. If you are arrogant and cocky, YOU WILL LOSE.
