It can be said that it is not! First of all, you got the patent right. You must be monopolized within the protection scope of this patent, but if you say that the market can be monopolized, it depends on the nature of your patent! If your patented technology belongs to the basic patent, it is very likely to monopolize a large number of markets! However, if we only improve on a certain point, or add some new technologies, the flexibility may not be as great as ideal!
You can probably understand it this way. If you don't understand anything, just ask! If you are satisfied, please adopt it.
