We've talked about making a GPLv3 release to at least open up the patents we control to all copyleft software. But there are important details to work through, and like most FLOSS projects we have more things to do than people to do them, so it hasn't happened yet. If someone needed it to happen it should be a pretty easy conversation to have.

Keep in mind also, our goal is generally to stay out of court. See above about having too much to do.
