What would that argument be? You have to find evidence that, years ago, before the patent was applied for, people knew about the same idea. And you'd have to find things today that demonstrate that they knew about it publicly at that time. So the dice were cast years ago, and if they came up favorably for you, and if you can prove that fact today, then you have an argument to use to try to invalidate the patent. And it might work.
