Copyright Holders
The text of the GPL is itself copyrighted, and the copyright is held by the Free Software Foundation. However, the FSF does not hold the copyright for a work released under the GPL, unless an author explicitly assigns copyrights to the FSF (which seldom happens except for programs that are part of the GNU project). Only the individual copyright holders have the authority to sue when a license violation takes place.
The FSF permits people to create new licenses based on the GPL, as long as the derived licenses do not use the GPL preamble without permission. This is discouraged, however, since such a license might be incompatible with the GPL. and causes a perceived license proliferation.
Other licenses created by the GNU project include the GNU Lesser General Public License and the GNU Free Documentation License.

Famous quotes containing the word holders:
“The doctrine of those who have denied that certainty could be attained at all, has some agreement with my way of proceeding at the first setting out; but they end in being infinitely separated and opposed. For the holders of that doctrine assert simply that nothing can be known; I also assert that not much can be known in nature by the way which is now in use. But then they go on to destroy the authority of the senses and understanding; whereas I proceed to devise helps for the same.”
—Francis Bacon (1560–1626)
