If I remember correctly the entire home 3D printing industry was held back by patents for decades. It was technically possible and feasible for much longer than we have commercially available 3D printers, but one or two businesses held all the patents and made it impossible to sell them cheap.
I’m starting to learn that patent trolling is a much bigger problem than we give it attention for.
The worst example I’ve heard so far is a US patent on fungi or mycelium as a plastic and styrofoam alternative. Think biking helmets or packaging material. That’s almost like granting a patent for wood as a construction material. It’s outrageous and seriously damaging progress across the globe because no one gets funding for something you can’t sell in the US.
The government has done nothing but spreading hatred against all sorts of foreigners since it’s infancy. They make no real effort to manage these issues, it’s the exact opposite. I mean the government clearly does not tolerate criticism against itself but they know people need to vent so racism became their channel of choice here. Even if you don’t know what the Chinese media landscape looks like, this is not difficult to figure out with an ongoing genocide and all.
