Trust Legal Provisions (TLP)

The IETF Trust was formed on December 15, 2005, for, among other things, the purpose of acquiring, holding, maintaining and licensing certain existing and future intellectual property used in connection with the Internet standards process and its administration, for the advancement of science and technology associated with the Internet and related technology.

Accordingly, pursuant to RFC 5378, Contributors to the IETF Standards Process grant the IETF Trust certain
licenses with respect to their IETF Contributions. In RFC 5377, the IETF Community has provided the IETF
Trust with guidance regarding licenses that the IETF Trust should grant to others with respect to such IETF
Contributions and IETF Documents.

These Legal Provisions describe the rights and licenses that the IETF Trust grants to others with respect to
such IETF Contributions and IETF Documents; as well as certain restrictions, limitations and notices relating
to IETF Documents.

The Trustees request that discussion of this topic be on the tlp-interest list, tlp-interest@ietf.org, with cc to
