Ren retslig har du næsten ingen chance, foruden at din domæne er et registreret worldwide varemærke (TM = Trademark). MEN selvom det er en trademark så skal du bevise at din tradmark tilmelding gik igennem FØR domænet blev registreret et andet sted. OSV osv..
Her står lidt om hvad du skal gøre

Someone else has registered my company's name as a domain name. What is the process for resolving my complaint?
All ICANN-accredited registrars follow a uniform dispute resolution policy. Under that policy, disputes over entitlement to a domain-name registration are ordinarily resolved by court litigation between the parties claiming rights to the registration. Once the court rules who is entitled to the registration, the registrar will implement that ruling. In disputes arising from registrations allegedly made abusively (such as "cybersquatting" and cyberpiracy"), the uniform policy provides an expedited administrative procedure to allow the dispute to be resolved without the cost and delays often encountered in court litigation. In these cases, you can invoke the administrative procedure by filing a complaint with one of the dispute-resolution service providers listed at <
