I don't know whether it answers your question, but ECMA does not approve 
"recommendations of Standards which are covered by patents when such 
patents will not be licensed by their owners on a reasonable and 
non-discriminatory basis". Also ECMA has a policy in regard to patents 
that were not known during the approval of the standard. See points 
1.3.x on the page http://www.ecma.ch/ecma1/MEMENTO/Code.htm

Best,
Jaak
