The "rights" in question are copyright.  Authors retain copyright in
derived works whether or not they know about them.  You get your own
copyright on your modifications when they are sufficiently novel to qualify
as an original work of their own.  There are few hard and fast rules for
determining this; it's typically determined by agreement between the
parties, or a court case.

The GPL, however, does not compel you to distribute your modifications back
to the author specifically.  If you distribute source with your binaries,
you do not have to give your modifications to anyone in particular.  If you
do not distribute source with your binaries, then you must give the source
to any third party who requests them within a period of 3 years after your
distribution of the binaries.

See the GPL more info.
