What is the recourse here? Would it be reasonable to contact the person that approved the patent with information showing that plenty flashcard systems precede this patent? I imagine there is some more formal system.
If you want to make a flashcard program, pray to gods Google will take pity on you and not enforce their patent. Otherwise, you better had set aside a couple of million dollars for the patent fight with Google. I mean, the patent will eventually get invalidated, but not before a decade in courts and millions of dollars in costs.
EDIT: Ignore everything I said. I got confused. I apologize. I am not going to change the original comment so the context of the replies would be preserved.
