Interesting views of Christian Nagel, even though I don’t share his „don’t bother with IP“ attitude.
It is, of course, true that a startup doesn’t have the funds for a patent law suit, if its patent is infringed. However, an infringed patent is exactly what Christian Nagel is looking for: proof of concept and relevance!
With that kind of strong proof, a startup can approach a competitor (there is always at least one) of the infringing company and partner up to sue the infringer.
This option might not be optimal, but it’s at least an option to defend the startup’s IP. Without a patent, there wouldn’t be an option at all.
