I don't think you understand the relationship between the specification
and IP. Specifically, whether OCB is in the main spec or a secondard
spec does not affect any IP/patent "problems". Put another way,
IP/patent "problems" occur for anyone who wants to implement OCB,
regardless of where it is specified. However having it in the main
draft makes it easier to implement and audit, as Werner suggested. The
more places you have to reference, the more likely you'll make a
Note that just because OCB is in the spec does not mean you must
implement it -- it's not going in as a MUST. If you don't implement it,
then there is no IP/patent worry on your part.
