Today I purchased a few new domain names, which are composed of very general words. When I attempted to purchase a different domain, adventure.app, I received warning of a trademark claim.
I chose to not purchase the domain (adventure.app), in fear of losing it through the trademark claim. However, the other domains I purchased are somewhat similar, though different topics. They are still composed of one general word.
For the domains I bought, I didn't receive a trademark warning. However, I am still afraid of losing them in the future, since if "adventure" is trademarked, I assume nearly every other similar sort of name will be trademarked.
Do I have any safety in now owning these domains before there was a trademark claim? Is there a place I can check for existing trademarks?
What about future trademarks? Should I try to buy the trademarks for these domains? I assume acquiring trademarks is a difficult process. I don't care about having the trademarks, as long as the domains aren't taken away.
One last addition - if somebody wanted to claim the domains through a trademark after I bought and own them, what would be the process? Would they be required to pay me for their value? Do I have any power to claim the domains as my own, since they are extremely general words? It seems like there should be a point where names are too general to be trademarked.
Note I don't have much experience with trademarks, which is why I'm here :)
