This, at an initial glance, almost looks like a patent troll move. You know, where those companies go out, patent a bunch of random stupid ideas with almost nothing to back it up or plans to use it in anything, then sue a ton of companies for violating their patents after they make it big.
They happen real often, and they don't ever plan on taking the thing to court or else they'd get creamed - they just do it for a few thousand dollars, and that's it. "I patented my idea for a sort of interface where you can control something with eye movement, but have no physical product to demonstrate it - just the idea!" Then someone makes it, it sells well, several people develop things for it, then the company goes out and sues all of them for violating their patent. Assume $50k a pop per settlement, and they sue maybe ten to twenty companies at a time, and that's a lot of cash for doing nothing.
Any time you see a lawsuit that claims a bunch of stuff like Disney, Microsoft, Sony, and Mattel - all in the same lawsuit - it's one of those things.
