A bunch of folks have been sending in the news that Microsoft has received a patent (7,813,570) on a method of GPU-accelerated video encoding. As some are pointing out, this broad patent appears to cover what many other companies are already doing. Once again, this should raise two key questions: if so many companies were already doing this, doesn't it suggest this was the obvious progression of the technology, and thus making it unpatentable? And, second, if so many companies were already in this space, doesn't it suggest that the incentives to build this kind of technology were already provided by the market, absent of the additional, market-limiting, incentives of the patent system?
