He certainly recognized that patents is a potential problem, x264 is a implementation of patented technology, however that problem is not tied to the licence no matter what jwr is trying to spin. And patents had nothing to do with them offering a dual-licence model, it was in order to be able to make money from their work when companies wanted to use x264 in a proprietary fashion (GPL is not compatible with proprietary), and from what I understand they have been doing great business this way.
