In all seriousness, I'm sympathetic to the idea that we should be careful about exactly what sorts of advances in biotech should be patentable. There is a legitimate debate to be had about how big the change should have to be to gain protection because obviously all new work is based on the past work of others (and mother nature herself).
But I don't think that admitting that we should be careful about where we draw the line means that we should have no line at all. There is legitimate biotech work that people are doing. Hard work. Expensive work. Good work. If we want this work to happen, then it makes sense to put in some sort of legal protection for it.
In the Monsato case, the patent covers every instance of those genes, whether they came from Monsanto or not.
Here's an article on the differences between copyright, patents and trademarks:
There's plenty of other entities that would be interested even without patents. Large agribusiness would be interested in increasing yields (your 'bigger banana'). Health organisations would be interested in dietary components (your 'vitamin A deficiency'), and it's not like research universities are forbidden from doing agricultural research.
Perhaps the facilitation of some research should be a function of the government vs. a for-profit endeavor.
So... you're saying that crossbreeding of plants and animals did not exist before corporations and patent law? That's just utter, utter, utter nonsense.
To be honest the whole thing was ill-conceived on every level anyway, but corporations and patent law alone were enough to doom it.
So now that you're saying that patents should only be for difficult things that takes years of education to do, why did you bother to talk about copyright above? You can write trash and it's covered by copyright. Plenty of trash is covered by copyright, stuff that didn't require education, discipline, or talent.
Copyright and patents are meant to protect novel things; how difficult they are to achieve is not really relevant, so sneering at 'that's just a bigger banana' is just elitism.
There is a balance to reach, and I think e.g. Monsanto has reached out quite nicely. For instance, both by law and contract, subsistence farmers may use even licensed breeds. You don't have to pay licenses to grow your own food. You only have to pay if you are utilizing the IPR commercially.
Same is with medicine: new medicines help curing people of diseases.
Your argument resembles a requirement for farmers to work for free because everyone needs food so it's wrong to charge money for it.
Why? Developing new biological technology is no different than developing other kinds of technology. It's difficult, expensive, and if you don't give the people that put in the effort and money to do it then it will never get done in the first place.
