Closed Standard
Definition
By the FFII:
"A specification normalized and licensed in any non free form indeed not public and not common for all the licensees (you have to negotiate with the owner of the IPRs). Specification itself could cost money but should be public (if not, it wouldn't be a standard). ECMA should be included in that category, since during its specification process doesn't warranty enough that Technical Committee members reveal its IPRs (patents mainly) covering the standard."
