I've got a sticky question.
About 5 years ago while working for a vendor (lets called them noisewindow...). I was setting up a personal lab (at home), and needed to do some testing with genuine certs and thus a genuine domain. I found that noisewindow.co.nz was not registered, so decided to grab it. At this time I notified the marketing team I was doing this and nobody was really interested.
One year ago I was made redundant as noisewindow shut down most of their APJ operations. So I decided to use noisewindow.co.nz more often doing some business of mine own (consulting). I have a proper website, email server, SPF records, DKIM setup, and DMARC even. All on both Ipv4 and Ipv6.
Today I got a call from someone at noisewindow in Aussie saying they are cleaning up all the global domains, and want me to hand over noisewindow.co.nz
I'm not adverse to giving it to them, however I will need to register a new domain, redo all my mail domains, websites, records, not to mention redo my mailserver (exchange). And of course let all my customers know my email has changed.
What are my rights here, they dropped a 'we'll go legal on you' hint. All I am really wanting is compensation for the above.
At the time of registration the company name was not trademarked, however I believe it is now.
