If its not there and you don't protect it then you can use it as can anyone else at the same time.
Worth doing a quick Google to see what comes up with any name that you choose and also do a webcheck to check out any incorporated version of it. Although quite different you don't want to go picking a name that is damaged goods.
i.e. I'm going to call my new business Enron. lol. bit of an extreme example there.
HTH Sam,
kind regards,
Shaun.
