The operative word here is uncertainty. A patent-holder creates uncertainty. How should an SDO respond? I'm not sure. I'm only sure that I don't like getting DoSed, either into dropping a standard or into not implementing it for fear of infringing. That's the nature of software patents: each one denies people the freedom to write and run certain kinds of software. This is why we must abolish software patents. Until we succeed in doing that, we can resist in certain ways. One of them is to refuse to establish standards that encourage their use. Generally speaking, standards are useful, because they enable people to converge what they are doing. But that ceases to be true when the use of the standard is patented. It is better to have no standard than have a standard that invites people into danger. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
