The PSF owns the Python language trademark:

   http://tess2.uspto.gov/bin/showfield?f=doc&state=4007:oc64of.5.1

Its trademark policy is given in detail here:

   http://www.python.org/psf/trademarks/

It also controls the license of the Python interpreter and its surrounding code. 
Contributors license their code to the PSF. Contributors keep the copyright to 
their code, but they agree to give the PSF the right to distribute it under a 
different license if the PSF decides to change licenses. See the Contributor 
Agreement:

   http://www.python.org/psf/contrib/contrib-form/

I believe they also outright own the copyright to most of the code that was in 
the Python 2.1 release and up until this Contributor Agreement was set up. I 
could be wrong about that, though.
