How Do New Metal Bands Protect Their Names?

I have noticed that many underground metal bands put a lot of effort into creating a unique identity with their names, logos, and artwork. As bands start releasing albums or selling merchandise, I wonder how they usually handle protecting their name from being copied or used by another group. Has anyone here dealt with trademark registration before? I recently came across IPDAS Trademark Solutions while looking into brand protection options and was curious about other musicians' experiences.
