The web page is here: http://concolato.wp.institut-telecom.fr/misc/mpeg-4-systems-patent-pool-analysis/ Of course, I'm no lawyer and this page carries only my interpretation. It’s worth no more than that, but still might be helpful for some discussions. If you think it's missing information or has incorrect information let me know and I'll fix it asap.
