As the realization of my online game is becoming apparent,
I need to totally lock down its name and domain as mine.
I got a domain stolen from me by some guy in New Zealand for another project. - I think some legal issue gave him clout over me. I got a note that it was being disputed with a legal branding, but I decided not to pursue it, as I felt it wasn't my best idea. This one is. This is my life's work, I think.
I own its domain. and don't want another one stolen. I didn't secure the legal stuff in time.
What are the legal steps to completely secure its name and domain globally, trademark etc. like this person in New Zealand did?
