Paul Vixie said: "in <http://www.theregister.co.uk/2007/09/21/802_11n_patent_threat/>, we see: Letters of Assurance are requested from all parties holding patents which may be applicable to any IEEE standard. Basically they state that the patent owner won't sue anyone for implementing the standard. ... i was thinking, what a great policy. why doesn't IETF have one like it?" Actually, this is a mistatement of what is in an IEEE letter of assurance. Check out the text here; it looks quite similar to an IETF IPR declaration form (e.g. no promise not to litigate): http://standards.ieee.org/board/pat/loa.pdf _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
