If you did this, then sued the author of a derivative work
I think your case that the author of the derivative work violated
your patent would be completely invalidated since you granted them
permission to do so under GPL. You can hold rights under
law but then subsequently relinquish them by announcing that you do so
(by releasing it under open source/GPL etc.)

My amateur understanding of software legalities.
