Yes.. Atari is going after everyone who is using their trademark name and logo.
They HAVE too, otherwise they lose their trademark.

"1. Failure to prosecute infringers. ?I can not tell you how important it is to
prosecute (prevent) trademark infringers from unlawfully using your trademark. ?If you do
not, your trademark is considered weak. ? Furthermore, if you take no action to prevent
infringers and their use of your trademark is overwhelming, you can lose your
trademark rights. ?Essentially, your trademark will lose its uniqueness
to your product or service."
Here is the case of Shelby losing the trademark of his Cobra because he didn't defend
it in the first place.

If you have a trademark and everyone copies it and you don't defend it, you will lose
it.
