Here is the problem:

I want to register a one word domain though I have found a German company that uses the exact word for one of their products with the trademark symbol. I checked all databases that I Googled up and found no registered TMs in EU, USA or Germany. Not even a similiar name. Zero results.

So.. I assume their claim the TM but don't have it registered.. But what to do to be 100% sure? I don't want to get in trouble.

Another question is, can I use the name if it is claimed but not registered??

EDIT: Googled it all up and seems I should avoid using the name to be safe.
