If you read Wall Streets reports, they dont talk of soya bean as originating in China. They dont talk of soya bean as soya bean. They talk of Monsanto soya. Monsanto soya is protected by a patent. It has a patent number. It is therefore treated as a creation of Monsanto, a product of Monsantos intelligence and innovation.
I have called this phenomenon of stealing common knowledge and indigenous science "biopiracy" and "intellectual piracy." According to patent systems we shouldn't be able to patent what exists as "prior art." But the United States patent system is somewhat perverted. First of all, it does not treat the prior art of other societies as "prior art." Therefore anyone from the United States can travel to another country, find out about the use of a medicinal plant, or find a seed that farmers use, come back here, claim it as an invention or an innovation.
It's a phenomenon that started in the United States in which corporations make claims on the life forms, biodiversity and innovations of other cultures by applying for patents on them.
