the Python Foundation

[Mark Tarver]

From the website

The Python Software Foundation (PSF) is a 501(c)(3) non-profit
corporation that
holds the intellectual property rights behind the Python programming
language. We manage the open source licensing for Python version 2.1
and later and own and protect the trademarks associated with Python.

Could somebody explain 'what holding the intellectual property rights'
means in this context and in what sense PSF manages the licensing and
protects the trademarks associated with Python? This is for my
education.

thanks

Mark

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.

[Steve Holden, Chairman, PSF]

The PSF requires that contributors sign an agreement licensing their
code to us, and allowing us to distribute it under the license of our
choosing (this does not in any way preclude the contributor licensing
the same code to any other party under different terms).

In this way people who use Python can be relatively sure that the code
is untrammeled by claims of copyright or patent by anyone other than the
PSF, and can therefore use it without fear of losing their rights to do
so because of legal action by third parties.

We have also registered the trademark "Python" for use in reference to
computer programming languages, thereby ensuring that we can take action
should some ill-advised individual or organization decide to produce
another language with "Python" in its name which we did not feel
conformed sufficiently strictly to the language definition, for instance.

The PSF has an established policy with regard to the use of its
trademarks, which you can read at

Steve

There has been a Lisp compiler called "Python" for many years:

[Rami Chowdhury]

The FAQ disclaims any connection and claims that Python the Lisp
compiler has been around longer than Python the language...

http://www.cons.org/cmucl/FAQ.html

I was awfully confused the first time I came across SBCL giving me warnings
about Python, though -- proves how well the PSF has safeguarded the name!

Thankyou to all on this thread for this clarification. I may return
and ask some questions if I need further clarification.
