They have definitely left a lot of wiggle room and you'd be crazy to build stuff based on their patents without a licensing agreement, but I think this signals that they are very open to licensing their technology, and are not trying to "build a moat". This would be a lot more interesting if they were willing to state the terms on which they are willing to license the patents, but there are probably complex legal issues with saying so explicitly.
