As with any patent, read the claims before making statements about what the patent covers. Patent titles are useless. With that said, at a quick glance it doesn't appear that it claims a novel electronic flashcard method, but there could be something I missed.
I mean, there is no such thing. It isn't possible to create something like that. Computers only perform a specific set of actions, and it doesn't matter how you put them together to do the flashcard thing. Or anything. There's nothing novel to be found. It's just math.
We should not grant artificial exclusivity over categories of functionality that computers were designed to provide.
Destroy all software patents.
