Obviously I am not a lawyer but the way I read it many people other than Red Hat are protected, but not quite all. If you develop your own project completely from scratch and you are violating this patent (which may or may not be dubious, RH never admitted to violating it or that it was legit) you are on your own. The licence of your wholely new and unrelated project is irrelevant. If you go and get your project accepted into Fedora (pretty easy task) you are then covered since Fedora is a RH brand. Now your upstream code from the Fedora project (and any predecessor code created before you got accepted into Fedora) is now covered by this licence so other distros or projects can take your work use, modify, and distribute it just like any GPL code and are legal. It seems from my reading of all the press over the last 2 days and the RH FAQs like the only condition that needs to be met is that code which makes use of this 'patent' exist in a Red Hat brand. If it exists, existed, or will exist, in Fedora everybody is covered. This is a great thing for RH to do to support all of us who use a RH supported distro or some other distro.
