Are you saying this is not the case with rtlinux? Seems to me that modified rtlinux can be distributed under the same terms as rtlinux. More generally, patents are an intractable problem for free software. Many patents have dubious viability (for example: often prior art exists). Note that in the U.S., a patent examiner's chances for advancement are based on how many patents they've approved. Prior art isn't even an issue in that context (except that denying a patent based on the existence of prior art would tend to reduce the number of patents which are approved). Also, it is impossible to guarantee that any piece of software is completely free of any patent. So, we basically ignore patent issues unless the patent holder becomes troublesome. Then we decide what to do on a case by case basis. -- Raul
