Both RFC 3667 and RFC 3668 contain an Intellectual Property disclaimer near the end of the document as defined in Section 5 of RFC 3668. But, this appears to only be required as stated in Section 5 for specific requirements: --------------------------------------------------------------------- 5. Notice to be included in RFCs The RFC Editor will ensure that the following notice is present in all IETF RFCs and all other RFCs for which an IPR disclosure or assertion has been received prior to publication. --------------------------------------------------------------------- Is it the intention to always include the IPR statement and the RFC Editor will only "ensure" it when an IPR disclosure has been made? Thanks again for your guidance, Sal Salvatore Mangiapane _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
