Re: Submissions to regulators must be public domain
Forgotten is that most of the research underlying development takes place in universities and other public institutions; it is funded by the state, by philanthropic institutions, and charitable donations; in so far as the concept of 'intellectual property' has any meaning ownership rests with the public. Much of what is written off as development is, particularly in the USA, aggressive marketing.
Many, but not all targets are found by public institutions; but the molecules that target them are usually invented by pharma/biotech (Academic labs do license molecules and then receive royalties eg Abiraterone). The real work is finding if the said molecules work in the test tube, then animals and finally in humans. The vast bulk of cost is incurred later in the process and I can't see many government wanting to pay a billion or so for developing a drug that the laws of probability say will fail...
