As long as the tits aren’t used for commercial purposes you don’t need a license. Anyway, I doubt that in Europe you could patent any naturally occuring molecules in any kind of milk.
Matlab is ugly because it’s so backwards compatible. And it only is backwards compatible until someone decides to use it to interface with external hardware that you need a specific version of some library for.
Maybe some countries’ patent offices don’t take their job serious, but in general there are loads of things you can patent. For example basically anything naturally occuring is not generally patentable, but you can patent methods for synthesising or extracting naturally occuring things.
