Miscellaneous Forums/General Discussion/Trademarked / copyrighted names

How can you find out if the (potential) name for your game is copyrighted / trademarked or someone has some sort of rights on it?

Say for example "Thrust" - I'm assuming you can't use that, but what if I wanted to call my game "Thrust Super Turbo Edition" or "Super Thrust"?
