Hi, I want to start a website and I heard that older domains tend to help site to rank better. I found & registered a domain name which was registered more than 10 years ago and it was expiring (it's a .com). The problem is that the .net & .org of this domain has been registered by a US LLC. company and the plural of the second word of the domain is also registered by another US LLC company(it's a 2 word domain). If I base a well-stablished website on this domain, can they later sue me and take this domain from me or not until they register the domain name as trademark? Thank you for your time
A trademark does not need to be registered - but it would be impossible to even speculate without knowing the exact domain name and the usage of these other sites. The fact that the domain you have used to be registered gives you no rights - you did not purchase the goodwill from the former owners so your date of usage begins whenever you start to use the site for a particular type of usage. A good trademark search will run a few hundred dollars and up. It's possible someone holds rights to the mark and don't even have a domain name - TM searches are complex and not as easy as simple match search.
Why cant you open up the domain name instead of telling all those stuffs? Like plural was rgistered,second work is that crap like that?? Just tell us the domain name and we would tell you if you can carry peacefully without legalissues or not
