Take for example a technical standard, that covers some communication protocol or any arbitrary mathematical algorithm. It is an idea of some kind. Could this technical standard be patented? Licensed? What is the legal status of such a standard? Could fixing this standard in any tangible form change anything in its patent-ability?
As far as I understand, should somebody implement the aforementioned communication protocol or algorithm in software or hardware, then this implementation becomes a separate entity and could in turn be patented and licensed. Am I correct? Could initial standard somehow prohibit creating such implementations? Could it require a license of some sorts for this?
