As you may be aware, RFC 3667 (BCP 78), "IETF Rights in Contributions," has been obsoleted by RFC 3978 (BCP 78), which was published in March 2005, and which bears the same title. The major difference between the two RFCs is that the IPR-related notices and disclaimers that the IETF requires in all Internet-Drafts have been updated to correct anomalies. The updated versions of the required notices and disclaimers are specified in Section 5, "Notices Required in IETF Documents," of RFC 3978, and in Section 3, "IPR-Related Notices Required in Internet-Drafts," of the recently revised "Guidelines to Authors of Internet-Drafts" (http://www.ietf.org/ietf/1id-guidelines.html). The "Guidelines" document also provides additional guidance regarding the placement of these notices. Currently, the IETF Secretariat accepts and posts Internet-Drafts that include *either* the RFC 3667 or the RFC 3978 version of these notices. However, as of 17:00 ET on Friday May 6, 2005, the Secretariat will accept *only* those Internet-Drafts that comply with the requirements of RFC 3978, and with the most recent version of the "Guidelines" document. Please note that the required notices and disclaimers must be reproduced verbatim since they have been legally reviewed and formally adopted as part of the IETF process. The Secretariat will not accept deviations from the specified text, nor will it correct the text. Any documents that do not comply with the requirements will be returned to the submitter.
