Not sure why you are downvoted, ( may be because of the tone and languages used ). But people from the academics, and companies do spend a lot of money on R&D in video encoding. These patents are not those silly one click web purchase patents, there are lots of thoughts, experiment into it. I would have thought anyone who has been to Uni / College would know this, after all it is part of how University gets funding these days.

The problem is price. What should these patents cost.
