Trade Mark issue

Hi All,

I submitted a module recently to CPAN (April 2, 2006) with the namespace 
Gtk2::Ex::MindMapView.

I've recently learned that the words "mind map" are are trademarked by 
the Buzan Organisation, Ltd. So now I'm thinking that I ought to rename 
my module before a legal eagle in the Buzan Organisation notifies me 
that I've violated their trade mark.

So, what is the best way to go about this? Can I remove a module from 
CPAN and later replace it with another renamed module?
