Two Nobel Prize winners want to cancel their own CRISPR patents in Europe

"But they make innovation thrive by providing an incentive to blah blah blah".

Not anymore in this day and age. Money comes mostly from the government, anyway, and plenty of really smart researchers would just be happy to put out their stuff out for the public benefit (and already do, btw). Even if they didn't the current patent system ends up giving them like 1% of profits, lol.

The business case for "but I want to protect the market I created" can be sufficiently solved with trade secrets and trademarks. Patents sound nice in theory, but in practice they only hinder innovation, the opposite of what they're supposed to do.

If I don't build it myself and can exploit myself, I get nothing and somebody else gets everything, so why shouldn't I just shut up completely? If I contribute something to the design of nuclear power plants, that the nuclear plant people would never come up with because people from my field, whatever that is, don't look at their stuff, then I obviously can't build my own nuclear power plant to compete with them.

The only way to ensure that people have an incentive to invest their time into things outside of the stuff they do to get money is by giving them patents.

Another reason patents are nice is that it's that you get something for your actual contribution. This means that it offers particularly skilled people who aren't rich a chance to actually build a company and have something real.
