If you replace IBM with 'A Patent Troll', do you think the same holds? I think not. If the IETF is going to have a policy on this, I believe it is important for the policy to treat everyone the same. I think that BOCU is a relevant example to show that promises to give a patent license is not good enough. (That is assuming my understanding of the BOCU example is correct; I haven't implemented or tried to get a license myself, I have only read about others who have done so.) If even IBM cannot do it properly, we have reason to not assume that others will be able to do it. Especially those less supportive of the free software community. > If we didn't know about the patent we would be happy to go use the > technology.

That makes no sense to > me. Agreed, it doesn't make sense. However, if somebody other than IBM proposes a technology and gives a patent license promise, I don't think we have a strong reason to suspect we will never be bothered by their patent. /Simon _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
