I think this patent has been mistakenly granted this year:

https://patents.google.com/patent/US20160021148A1 (see the "grant" status line)

I think it should not have been granted there being prior art, but for it to be turned over, I think it would have to be challenged in court. That's my limited understanding as a non-US person without any experience with patents whatsoever.

Oh wow, I am shocked to see the patent was granted and I'm very interested in understanding the repercussions. These might be big.
