FSF Licensing & Complaince
The Compliance Lab has been an informal activity of the FSF since 1992 and was formalized in December 2001. We handle all licensing-related issues for FSF. We serve the free software community by providing the public with a "knowledge infrastructure" surrounding the GNU GPL and free software licensing, and enforcing the license on FSF-copyrighted software.
What We Do
Our biggest task is educating users and developers working with free software about our licenses and related issues. We offer a number of resources to provide this information, from essays and FAQs to speeches and seminars. If none of that helps, we'll be happy to answer your question via e-mail. Learn more about free software licensing.
In order to stay effective, a license must be enforced. The FSF holds the copyrights for many popular free software programs, such as GCC and glibc, and we enforce those licenses. We investigate all reports we receive about free software license violations, and negotiate with violators to bring them into full compliance. Learn more about our compliance work.
While license education and enforcement are the focus of our efforts, we deal with all issues related to free software licensing. We help coordinate the license revision process, evaluate requests for license exceptions, and more.
GPLv3 Action
Have you seen news reports that mischaracterize GPLv3? Or forum posts that spread incorrect information? Help us fight it! We can't address all of these ourselves, but with the community's help, we can do a lot to help people talk about GPLv3 accurately. Let us know what you find, too—we may try to address it ourselves one way or another, or perhaps use it to improve our GPL FAQ.
Would you like to have someone speak to your organization about GPLv3 or other GNU licensing issues? FSF Licensing Compliance Engineer Brett Smith is happy to talk to groups about a wide variety issues. Please contact us for details.
Who We Are
The Compliance Lab relies upon the efforts of many people, from volunteers pitching in a few hours a week to full-time attorneys. If you're interested, we'd love to have your help. Learn more about the Compliance Lab team.
