How revolting. Nothing in what was described in your updated link below looks even remotely novel even years before the 2016 filing date.

I say this as someone who was deeply involved in the industry in the late 2000s. I also contributed to Anki in that time frame.

This patent is just for the business owners vanity. It's clearly not defensible in courts. Even if it was, they probably don't have the money required to pursue court enforcement of the patent. More so when any reasonable lawyer will tell them they'll get their case dismissed anyway.

Yeah I don't understand how this can be a patent.

For example Skinner's Learning Machine as well as any automatic implementation of Pimsleur's method, both described in the SIXTIES, would fall under this (according to my reading, I'm not a patent lawyer, hamdulillah).

Absurd.
