If the non-profit's constitution said it could not sell the intellectual assets created from its activity, that might prevent a new for-profit from acquiring them (even a subsidiary of the non-profit), except on licensed terms. I don't know of any non-profit which has a condition like that in their constitution. However, they do often have an "asset lock", which would require assets are sold at fair market value, not given away, profits are not distributed etc. Seems to me, an "intellectual property asset lock" could be constructed along similar lines, if people really wanted to. It might be a bad idea, though, if the non-profit folds, or would benefit from being restructured. Something allowing contribution to Open Invention Network or similar might be better for the long term.
