Yes, my article on this states: "t's important to note the difference between MPEG, the standardization body, and MPEG LA, the licensing agency. MPEG defines standards, and those can be royalty-free or royalty-bearing, depending on what the owners of the essential patents agree upon in each case. MPEG LA manages patent pools related to royalty-bearing standards, serving right holders and licensees as a one-stop solution by way of aggregation."
