No granted monopoly ever that I know of, spawned innovation.

Knowledge of innovation was spread by several means. Workers who were trained in the technique might move to another employer or might be poached. A common method was for someone to make a study tour, gathering information where he could. During the whole of the Industrial Revolution and for the century before, all European countries and America engaged in study-touring; some nations, like Sweden and France, even trained civil servants or technicians to undertake it as a matter of state policy. In other countries, notably Britain and America, this practice was carried out by individual manufacturers anxious to improve their own methods. Study tours were common then, as now, as was the keeping of travel diaries. Records made by industrialists and technicians of the period are an incomparable source of information about their methods.

The thing that enable the Industrial Revolution was by far the free flow of ideas and the easy of deployment meaning there was no legal threats that could stop others from implementing anything, they learned and implemented what they needed and further developed and build upon what they gathered, that is what enabled the revolution not IP law which is a problem for the free flow and use of ideas.

No granted monopoly ever that I know of, spawned innovation.

What we see today is the total paralyzes of the industrial park in America because of it, a few big players are getting bigger and bigger at the cost of the little ones that are increasingly being squeezed out of the market and that will end the same way it ended every other time, with people breaking the law getting punished and eventually violence will breakout again, because the small players too need to find a way to make some money and they will get tired of being deprived of knowledge that could make that happen.
