that is such a horrible broken system, it makes me mad every time I hear about it. Also, technically, they could also give a one-off license the copyright under specific ("your game is nothing like mine") circumstances.A lot of these types of copyright notices are never expected to win, but are done to protect the IP. For instance, the whole issue with KING trying to shutdown the use of "Saga" (by suing the Banner Saga peeps) was to give their upcoming copyright claim more weight. Now KING lost that claim but their hands were tied if they wanted to have the best case possible. You have to protect your claims in every instance you are made aware of or someone can go to a judge and say "See how this company isn't defending their copyright, despite our clear use of it? They've abandoned it and it belongs in the public domain." That'll lead to a long, expensive lawsuit.
