What I don’t understand is, _how_ it doesn’t depend on a patent right. How do you license something that doesn’t depend on a licensable right?

If it isn’t a patent right, exactly _what_ is he purchasing a license to? If it’s purely an agreement of exclusivity to Giumarra, it can’t be called a “sub license” and the consequence is just a breach of contract (which is what it sounds like). But in that case I’m sure there are mutual termination agreements in the exclusivity contract.

Also, if it’s _not_ a patent, what exactly does the company bring to the table? For what consideration does the farmer give them an exclusive access to his trees?
