All 3 are design patents, which are patents on non-functional ornamental design of functional items. They aren't patenting side doors, they are patenting the way the side doors look.
Pure patent troll rubbish.
I had thought that maybe design patents were a new thing, but a little research shows they aren't. The first was in 1842, and the Coke bottle in 1915 is a notable example. https://en.wikipedia.org/wiki/Design_patent
The only ray of light is that a design patent is invalid if the design has a functional benefit.
The patent applications were filed on Dec. 30, 2015.
Patent applications aren't granted overnight.
