Legend
Was that actual case law or statute at the time?TSR (and Gary) were zealously guarding the IP, because at the time it was perceived that any infringement not addressed automatically made it public domain.
A trademark has to be defended, if it's being used in trade by someone else. . .a copyright doesn't.
Also, to lose a trademark it generally has to be used either generically and they don't take efforts to fight the genericization, or it has to be used in trade by someone else.
Is a fan website with someone posting a text-file netbook of their homebrew campaign setting really using it "in trade", if the file isn't being sold?
Either interpretations of IP law have changed a LOT in the last quarter century, or the TSR legal dept. was absurdly over-cautious. They wouldn't be the only one like that though, for a while, Paramount had much the same attitude about Star Trek fan sites.
