Soon no one will be able to do stuff on their own, as they will be sued into oblivion just for thinking about something.
I believe that's the point.
By the time these large companies patent everything and claim ownership of 'innovations' which had been around for years or were widespread knowledge already, the goal is to more or less ensure there's not a damned thing you can do with technology for which you won't be beholden to them.
It's rent-seeking on a large scale, and the governments are just handing it over to them.
At a certain point, it will be impossible for new companies to create anything at all, because the web of patents and the like will be so extensive we'll have only a few large players.
Welcome to the oligarchy of the future. It will only keep getting worse.
