Earlier quoted context omitted.
The problem with research is that you are supposed to be creating novel works, not derivatives. This means you are creating IP, not modifying.
All research builds upon previous ideas. E.g. you can patent a novel idea that would require licensing another patent to use.
sure to build a new system, you might need other patents. but a pateent it's self should be unique enough to defend. Which means its copyrightable as its own thing
