Wasn't there a patent on the message passing part of the QnX kernel?
- jacquesm 11y agoI don't know. Frankly I don't give a rats ass if there is or isn't but if there is such a patent it would now be the property of RIM (or whoever gets it after RIM folds). Message passing pre-dated QnX by a considerable time, they just did a really nice and clean implementation of it. I'd absolutely support their copyright claims on their code, at the time their implementation was unique but I'd totally object against any patent claims, message passing systems had been used widely by that time, also at the kernel level. QnX may have been the first microkernel on that principle that received wide adoption because of the strength of the implementation.
