Thx for reply.
Sorry I got confused with Copyright and Trademark, english is not my mothertongue.
In fact I did read alot, and I know google...but its seems this is a much more complicated field I thought. I have read walls of Text but at the End I still had no clue. Isnt there a "Law for Dummys" out there ^^ ?
How to be sure to not get sued later on. I cant just type the Name in google, and if there are no results then everything is fine I think..
