All that suggests is that patents produced by academia have a really crappy ROI. Not surprised at all, given how little incentive academia has to produce marketable products.

Also, you directly contradict yourself when you state that (1) patents unfairly enrich their holders and (2) patents provide a poor ROI. Which way is it?

Example of what you said earlier -- you keep commenting under two different accounts.

>> [ME] Do patent protections provide them an incentive to do that research?

> [YOU] The main incentive is money, patents are seen as a moat to that
