Talk:List of United States MPEG-2 patents

32nd of the month?
As I mentioned using the template, there are three dates which cannot possibly be correct because they claim to be the 32nd of some month. I don't remember the rules for US patent expiration off the top of my head, which is why I am asking for help here. --SoledadKabocha (talk) 03:15, 25 July 2017 (UTC)
