The patents on substantial technologies of MPEG-2 will soon expire.
More precisely, 50% of the MPEG-2 patent pool (134 US patents, including the 27 original 1996 MPEG-2 IPR Working Group’s patents) will expire by October 16, 2012. The remainder dribble out for several years through various patent life-extension techniques (continuations, divisions, and patent term adjustments).
I prepared these materials to assist MPEG’s consideration of a royalty-free MPEG standard. Presentation MPEG-2 Patents, spreadsheet MPEG-2 Patents List (also in MPEG-2-Patents-List xls format). Also a presentation on MPEG-2 Systems Patents.
