Incorrect. Patents quite literally to provide the developer of a new technology a legal monopoly for some time so they can (maybe) recoup their costs as an incentivisation mechanism to encourage innovation.
When I'm looking to spend money to solve a problem, I search for a product or service to buy.
I never, ever, ever search for a patent to license, because that's stepping into a legal minefield.
Show me a field where people looking to spend money to solve a problem search the patent database for solutions, and I'll believe there's a field where patents are a good thing.
