In my opinion, it should be obvious to anyone skilled in the art that this patent should not have been issued and those who filed it and approved it have participated in a fraud against the US legal system.
Sadly, that's not how the patent system is setup in the US. It rewards companies who try to file as many patents as possible and see if they can get those patents granted. It falls on the USPTO to validate and grant those patents.
As the USPTO is underfunded and understaffed, a lot of possibly invalid patents are granted.
