In some cases it makes perfect sense to charter a group that will be using encumbered technology. In other cases the entire purpose of the group requires that any technology be open and unencumbered. We've been round that argument enough times that it's become a tradition. A priori rules like that make no sense for the IETF. 1. They inhibit innovative thinking within the WG process, because they mean that the major technical options must basically be decided before you start, so that you can decide which IPR regime is going to work. And if you decide a priori to be RF, the available solutions are dramatically constrained. Or to say it more emotively: all the good ideas have been patented anyway. 2. They would assist the patent trolls, who could make sure to quietly acquire patents that encumber the 'royalty free' solution just in time for the standard to be widely adopted. Leaving the choice until later in the process isn't perfect, but it reduces these two risks and matches the reality of IPR laws and practices, which are heavily based on RAND and reciprocity, like it or not. IMHO, as always. Brian _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
