I find it repulsive that his first recommendation to “inventors” is to file for a patent. Really, the most valuable piece of advice you have is “make sure you secure legal protection in case other people rip you off”? By all means, that's probably a thing you have to think about at some point, but surely there is more important advice for creatives than “lawyer up”.

One of Dyson’s well-known paths might be wielding patent laws against competitors.
