They made the patent, that means Sony is interested in blocking used games. Maybe not now, maybe in the future, maybe is for 3rd parties alone, maybe for themselves. Nobody really knows, but it gives us a lot of room to speculate, especially since MS is doing it.

Sony has been filing patents like this for years. It doesnt mean it will be implemented. It really doesnt give us room to speculate. Sony already shot down online requirements and the purpose of blocking used games is to increase revenue which this patent wont do. 

To my knowledge Sony has only made 2 patents in relation of used games: this one and one early in the PS3 life. One could very well argue that the first patent became what we know now as online passes. 

Everything is PR talk, we have evidence (in the OP) that Sony first party games won't be blocked, BUT there's nothing stopping 3rd parties for doing it, they are doing it with the Xbone, they are going to do it for the PS4 as well. 

Not every 3rd party publishers will implement pay walls, but if we see an increase in profits coming from EA and Activision (the ones that are most likely going to block used games) then other publishers will follow suit, no question asked. Will that happen? nobody knows, we just have to wait a couple of years and see.
