why aren't patents considered a major cause of the Industrial Revolution? Doesn't it provide the incentive for the inventors to invent because it protects their invention? I mean, why do inventors all get patents? Why do they fight so hard to get it? And why do they try so hard to enforce what their patents are supposedly granting them, like why do they try so hard to collect on royalties?
Which one? There is the first one and second one, which the Bessemer process is usually credited with as the staring point, and then there are mini-industrial revolutions like the one during the Song dynasty.
