I don't think that's how copyrights work either. As far as
I know, whether something is deemed a derivative work is
judged on the basis of how similar it is to another work,
not whether its author had knowledge of the other work.
As long as you express an idea in an original way, it
shouldn't matter where you got the idea from.
